Which Shower Curtain Liner Actually Stops Mildew in 2026?#

What is the best mildew-resistant shower curtain liner?

The best mildew-resistant shower curtain liner in 2026 is the LiBa Shower Curtain PEVA 8G at $16.99, because its heavy 8-gauge PEVA construction, three bottom magnets, and 12 rust-proof metal grommets outperform thinner liners in both mildew prevention and long-term durability. For fabric-liner buyers, the Zenna Home Soft Microfiber Liner at $9.39 is the top machine-washable choice. The Epica Waterproof Shower Curtain Liner at $22.49 leads the premium tier with stain- and odor-resistant treatment built into its PEVA compound. Avoid any liner thinner than 6-gauge - Bob Vila testing found 8-gauge PEVA outlasts 4-gauge versions by 4–6 months before showing visible mildew in humid bathroom conditions ^[4].

Mildew on a shower curtain liner is not just an aesthetic problem - it signals an active fungal colony releasing spores into the air you breathe every time you shower. The material, gauge thickness, and bottom-weight design of a liner all determine how quickly mildew takes hold. PEVA and EVA liners release significantly fewer volatile organic compounds than traditional PVC liners, making them safer for enclosed bathroom spaces ^[2]. In 2026, the market has matured enough that you can find genuinely mildew-resistant liners at every price point from $7.92 to $22.49 - but the differences in construction quality are substantial and directly affect how long your liner stays clean.

We evaluated seven shower curtain liners across material type, gauge thickness, weighted-magnet performance, grommet rust resistance, and long-term mildew resistance, drawing on expert lab testing from The Spruce, Good Housekeeping, Wirecutter, Bob Vila, and Forbes Home ^[1]^[2]^[3]. Whether you need a durable daily driver for a family bathroom or a low-cost liner for a guest bath, the ranked options below cover every scenario.

LiBa PEVA 8G - Is This the Best All-Around Liner Under $20?#

Best for: Renters and homeowners who want a reliable, set-and-forget 8G liner with proven mildew resistance at a mid-range price - the best single purchase for most primary bathrooms.

№ 1Best overall

LiBa Shower Curtain PEVA 8G

4.6$9.98$16.99Save 41%

The LiBa PEVA 8G is the best all-around shower curtain liner for most households at $16.99 - heavy 8-gauge construction, rust-proof grommets, and three weighted magnets deliver mildew resistance that rivals liners costing twice as much.

Check price at Amazon

What we like

Heavy 8-gauge PEVA resists mildew and discoloration significantly longer than 4G or 6G liners
12 rust-proof metal grommets with reinforced header prevents tearing over repeated use
Three bottom magnets keep the liner flat against the tub, eliminating moisture pooling
PVC-free and chlorine-free - fewer VOCs than traditional vinyl liners from day one

What we don’t

Clear finish offers no privacy if used without a fabric outer curtain
New liner has a mild plastic odor that dissipates within 24–48 hours of hanging

value10.0

durability9.0

mildew_resistance9.0

The Pitch

LiBa markets this liner as a heavy-duty alternative to the thin 4G and 6G liners that dominate the under-$12 tier. The 8-gauge PEVA compound is noticeably thicker to the touch - it drapes flat rather than billowing, which is the first line of defense against moisture accumulation at the tub edge. The ultra-smooth surface is engineered to promote water bead formation so water rolls off rather than spreading into standing film.

The Experience

The three bottom magnets are strong enough to hold the liner against standard enameled and acrylic tub surfaces even during high-pressure showers. Good Housekeeping's Cleaning Lab consistently ranks PEVA liners above PVC for water repellency and ease of cleaning ^[2]. The reinforced header prevents grommet tearing even after repeated hook insertions - a failure point on cheaper liners that becomes frustrating within weeks.

The Catch

At 72x72 inches, this liner fits standard tub/shower combos but not stall showers or walk-in configurations. Buyers with non-standard tub heights should measure before ordering. The clear finish also means this liner works best paired with a fabric outer curtain for a finished, polished look in a main bathroom.

Before you buy

If your bathroom has poor ventilation, pair this liner with the habit of spreading it fully open after each shower so it air-dries completely - that single step prevents most mildew growth regardless of liner quality {REF:3}.

GORILLA GRIP Waffle Fabric Curtain - Best Premium Fabric for a Spa Bathroom?#

Best for: Homeowners upgrading a main bathroom who want a premium waffle-weave decorative curtain and are prepared to pair it with a separate $8–$17 PEVA liner for water protection.

№ 2Best fabric curtain

GORILLA GRIP Gray Waffle Style Textured Fabric Shower Curtain

4.4$18.35$23.94Save 23%

The GORILLA GRIP fabric curtain at $23.94 delivers hotel-quality aesthetics and long-term durability, but it is a decorative outer curtain - not a waterproof liner - and requires a separate PEVA liner for full water containment.

Check price at Amazon

What we like

230 GSM thick fabric is wrinkle-resistant and fade-resistant for long-lasting appearance
12 rust-resistant grommets allow easy installation with any standard hook set
Waffle-weave texture adds luxury spa aesthetics to any bathroom
72x78 inch sizing fits taller shower configurations that standard 72x72 liners miss

What we don’t

Not a standalone liner - requires a separate waterproof liner for water containment
Higher maintenance than plastic: fabric curtains need regular machine washing to prevent mildew
At $23.94 for a decorative curtain, total setup cost rises to $31–$41 when paired with a liner

value7.0

durability9.0

mildew_resistance7.0

The Pitch

Gorilla Grip positions this as a hotel-style decorative curtain with superior fabric weight. The 230 GSM weave is significantly heavier than standard polyester shower curtains, which translates to better drape, reduced billowing, and a noticeably more upscale appearance than the thin fabric curtains that ship with budget sets.

The Experience

The weighted hem keeps the curtain hanging straight outside the tub in its correct position as a decorative layer. The Spruce identifies weighted fabric curtains as a top mildew-prevention pairing when combined with a PEVA liner, because the outer curtain stays dry while the liner handles direct water contact ^[1]. Superior quality stitching ensures the curtain holds its shape through repeated machine washing.

The Catch

This is explicitly not a waterproof liner - buyers expecting standalone water barrier performance will be disappointed. For a complete bathroom setup, budget $23.94 for this curtain plus $7.92–$16.99 for one of the PEVA liners reviewed below. The liner is not included and is not optional.

Before you buy

The Gorilla Grip brand is well-known for heavy-gauge PEVA liners, but this specific product is a fabric curtain. Budget accordingly - a complete setup requires this curtain plus a liner like the LiBa 8G or Amazon Basics.

Zenna Home Microfiber Liner - The Best Soft Fabric Liner Under $10?#

Best for: Allergy-sensitive households and anyone who finds the feel of a plastic liner against their skin uncomfortable during showering - provided the bathroom has adequate ventilation.

№ 3Best budget fabric

Zenna Home Water Repellent Shower Curtain Liner

4.3$9.39

The Zenna Home microfiber liner at $9.39 is the best fabric liner at this price - machine-washable, water-repellent, and noticeably softer than any plastic liner, though it requires more active maintenance to prevent mildew than an 8G PEVA alternative.

Check price at AmazonOnly 1 left in stock - order soon.

What we like

Ultra-soft microfiber fabric is comfortable against skin in a way no plastic liner can match
Machine washable - a monthly warm cycle removes mildew before it becomes visible
Water-repellent coating causes water to bead and run off rather than soaking in
Weighted hem at the bottom keeps water inside the tub without adhesive magnets

What we don’t

Fabric holds moisture longer than plastic - requires monthly washing to stay mildew-free
Water-repellent coating degrades over time, especially with high-heat dryer cycles
70x72 size is slightly narrower than standard 72x72 liners - verify tub dimensions first

value10.0

durability8.0

mildew_resistance7.0

The Pitch

Zenna Home's microfiber liner targets buyers who dislike the look, feel, and chemical smell of plastic liners. The water-repellent finish performs similarly to a light DWR (durable water repellent) coating - water sheets off the surface rather than soaking through, keeping the outer face dry during normal shower use.

The Experience

In well-ventilated bathrooms, this liner performs admirably with a monthly machine wash. Good Housekeeping's Cleaning Lab notes that machine-washable fabric liners last 2–3 years with proper care - two to three times longer than budget plastic liners replaced every 6–12 months - making them better long-term value despite higher active maintenance ^[2].

The Catch

The water-repellent coating is the weak link. High-heat dryer cycles degrade it faster than air drying. Wash in warm water, tumble dry on low or hang to air dry, and never use a hot setting - doing so accelerates coating failure and sharply reduces the liner's effective mildew-resistant lifespan.

Before you buy

Wirecutter recommends plastic liners over fabric for bathrooms with poor ventilation - plastic drip-dries in under two hours while damp fabric can harbor mildew overnight in stagnant air {REF:3}. If your bathroom lacks a window or exhaust fan, choose the LiBa 8G PEVA instead.

Barossa Design PEVA Liner - Best Budget Plastic Liner at $9.99?#

Best for: Budget shoppers who want a clean white, PVC-free liner they can replace inexpensively every 6–12 months rather than investing in a premium liner they'll need to maintain actively.

№ 4Best budget plastic

Barossa Design White Shower Curtain Liner Standard Size

4.2$9.99

The Barossa Design PEVA liner at $9.99 delivers solid PVC-free construction with 3 bottom magnets and 12 metal grommets - priced low enough that replacing it every 6–12 months costs less than premium cleaning products used to maintain a higher-tier liner.

Check price at Amazon

What we like

100% PEVA material - no chemical odor, PVC-free, and BPA-free from the moment it ships
Three bottom magnets and 12 metal grommets keep the liner stable and correctly positioned
White finish pairs cleanly with virtually any decorative shower curtain color
Reinforced header prevents top holes from tearing during installation

What we don’t

Gauge weight not specified - likely lighter than the LiBa or Amazon Basics 8G liners
No antimicrobial treatment in the PEVA compound - relies entirely on material quality
White color shows soap scum buildup more visibly than clear liner options

value9.0

durability7.0

mildew_resistance7.0

The Pitch

Barossa Design focuses on PVC-free safety and a clean white aesthetic. The no-odor claim is genuine - PEVA off-gases at a fraction of the rate of PVC, so new-liner chemical smell is minimal and dissipates quickly in any ventilated bathroom.

The Experience

The three magnets hold well against standard acrylic and enameled tub surfaces. The reinforced header prevents grommet tearing during initial hanging - a failure mode that makes cheaper liners frustrating to install without immediately damaging the top edge through which hooks must pass.

The Catch

The gauge is likely lighter than the LiBa and Amazon Basics 8G liners based on price positioning. In Bob Vila's comparisons, lighter-gauge liners typically show visible mildew 4–6 months earlier than 8G equivalents under identical bathroom conditions ^[4]. Build a liner replacement into your routine every 6 months rather than waiting for visible mildew.

Before you buy

Forbes Home notes that antimicrobial additives built into the PEVA compound - absent in this liner - are what distinguish premium liners from economy options in high-humidity bathrooms {REF:5}. In a moderately humid bathroom with good ventilation, this liner performs adequately; in a damp, poorly ventilated space, step up to the LiBa 8G.

Amazon Basics 8G PEVA Liner - The Cheapest Liner Worth Buying in 2026?#

Best for: Guest bathrooms, short-term vacation rentals, and anyone who wants genuine 8G mildew-resistant construction at the absolute lowest available cost.

№ 5Lowest price

Amazon Basics Water Resistant 8-Gauge PEVA Shower Curtain Liner

4.3$7.92

The Amazon Basics 8G PEVA liner at $7.92 - the lowest price on this list - delivers genuine 8-gauge PEVA construction with rust-proof grommets and includes plastic hooks, making it the single best value for guest bathrooms and rental properties.

Check price at Amazon

What we like

Genuine 8-gauge PEVA at the market's absolute lowest price point of $7.92
Includes plastic hooks - eliminates a separate $5–$8 accessory purchase
Rust-proof metal grommets prevent staining on both the liner and any decorative curtain behind it
PVC-free formulation reduces VOC off-gassing compared to traditional vinyl liners

What we don’t

No bottom magnets - the liner can billow inward during high-pressure showers
Clear-only finish; no frosted option available for buyers who want privacy
Basic construction - no antimicrobial additives or premium reinforced header stitching

value10.0

durability8.0

mildew_resistance8.0

The Pitch

Amazon Basics positions this as the no-nonsense utilitarian liner: 8-gauge PEVA, rust-proof grommets, and included hooks with nothing extra charged. The inclusion of hooks is a genuine value-add that most competitors at this price omit, requiring a separate purchase before you can even hang the liner.

The Experience

The 8G construction is the real story here. For $7.92, you get the same gauge thickness that Bob Vila identified as the key differentiator for long-term mildew resistance ^[4]. In a guest bathroom that sees infrequent use, this liner will outlast its price point by a significant margin and likely needs replacement once annually at most.

The Catch

Daily-use primary bathrooms will miss the bottom magnets. The liner billowing into your leg mid-shower is a minor but recurring annoyance - and a minor humidity issue, since the liner touching your body pushes it away from the tub edge where it should rest. Upgrade to the LiBa 8G for $9 more if this is your household's main shower.

Before you buy

The absence of bottom magnets is the key trade-off at this price. Without them, the Bernoulli effect during showering pulls the liner inward - an annoyance that the weighted LiBa 8G eliminates for only $9 more. For a primary daily-use bathroom, spend the extra $9 {REF:3}.

Epica Waterproof Liner - Worth the $22.49 Premium for Mildew Protection?#

Best for: Homeowners with chronic mildew problems or high-humidity bathrooms where standard PEVA liners show visible mildew growth within 2–3 months of installation.

№ 6Best premium

Epica Waterproof Shower Curtain Liner

4.5$22.49

The Epica Waterproof Shower Curtain Liner at $22.49 is the best choice for high-humidity bathrooms where mildew is a chronic problem - its stain- and odor-resistant PEVA compound and reinforced nylon mesh header with rust-proof metal grommets justify the premium over budget alternatives.

Check price at Amazon

What we like

PEVA compound specially treated to resist stains and odors - not just a surface coating that wears off
Reinforced nylon mesh header with rust-proof metal grommets resists tearing and long-term corrosion
Premium material selection means fresher-smelling showers between cleaning sessions
Clear finish maintains a bright, open feel in smaller bathrooms where light matters

What we don’t

At $22.49, it costs nearly three times the Amazon Basics option for incremental daily-use benefits
No weighted bottom magnets - a surprising omission at this price tier
Clear-only option limits decorative flexibility for buyers who want a frosted or colored liner

value7.0

durability9.0

mildew_resistance10.0

The Pitch

Epica's liner is built on the premise that mildew prevention starts in the material itself, not with cleaning products applied after the fact. The stain-resistant, odor-resistant PEVA compound is engineered to repel both soap scum and mildew spores at the surface level - unlike standard PEVA that relies entirely on the plastic's inherent smoothness.

The Experience

The reinforced nylon mesh header is a standout durability feature - it distributes stress across the fabric rather than concentrating it at each grommet hole, which is the first failure point on cheaper liners. Epica's construction quality is immediately apparent when holding the liner: the material feels premium and the grommets seat cleanly without rough edges.

The Catch

The omission of bottom magnets at this price is a notable gap. Buyers in humid climates who purchase the Epica liner should pair it with the habit of spreading it fully open after every shower - the single most effective free mildew prevention step - to compensate for the lack of magnetic bottom sealing ^[1].

Before you buy

Forbes Home highlights that antimicrobial additives built into the PEVA compound - as opposed to spray-on surface treatments - reduce visible mildew growth by resisting spore attachment from first use {REF:5}. This built-in compound treatment is Epica's core technical advantage over every other liner on this list.

value9.0

durability7.0

mildew_resistance8.0

The Pitch

iDesign (formerly InterDesign) has been a trusted home accessories brand for over four decades. The PEVA liner is marketed specifically on mold and mildew resistance, and the 2-pack format is designed for buyers who understand that rotation between liners is a proven mildew-prevention strategy that costs nothing but planning.

The Experience

The bottom magnets are functional and hold against standard tub surfaces. The reinforced grommets hold up to regular hook insertion and removal - important for buyers who genuinely rotate liners weekly. At $5.50 per liner, replacement economics are as favorable as the Amazon Basics single-liner option.

The Catch

The gauge weight is not specified, which is a transparency gap compared to brands like LiBa and Amazon Basics that prominently advertise 8G construction. Based on Bob Vila's testing ^[4], gauge directly correlates to how long a liner resists visible mildew - an unspecified gauge liner warrants closer monitoring and earlier proactive replacement.

Before you buy

Rotating between two liners - using one while the other air-dries completely - is one of the most effective mildew prevention strategies available. The 2-pack format makes this habit practical and affordable. If gauge transparency matters to you, the LiBa 8G is the safer guaranteed-gauge alternative.

What is the best mildew-resistant shower curtain liner under $10?

The best shower curtain liner under $10 in 2026 is the Amazon Basics 8-Gauge PEVA Liner at $7.92, because it delivers genuine 8G PEVA construction - the gauge thickness Bob Vila identified as lasting 4–6 months longer than 4G liners before showing mildew ^[4] - along with rust-proof metal grommets and included hooks at the market's lowest price. If a white liner with bottom magnets is preferred, the Barossa Design PEVA Liner at $9.99 is the best under-$10 alternative. Both are PVC-free and appropriate for guest bathrooms or low-frequency-use showers where the absence of bottom magnets is an acceptable trade-off.

What Should You Look for in a Mildew-Resistant Shower Curtain Liner?#

The criteria below are the ones that actually determine mildew resistance in real-world bathroom conditions - not marketing claims. Matching these specifications to your specific bathroom environment (humidity level, ventilation quality, shower frequency) is the most reliable way to choose the right liner ^[4]^[5].

Material type: Choose PEVA or EVA over PVC - both are PVC-free, release fewer volatile organic compounds, and resist mildew without the chlorine-based compounds in traditional vinyl liners.
Gauge thickness: 8G is the minimum for meaningful long-term mildew resistance - Bob Vila testing shows 8G PEVA outlasts 4G liners by 4–6 months in humid bathrooms.
Bottom magnets: Three weighted magnets are nearly essential - they prevent the Bernoulli effect from drawing the liner inward and eliminate moisture pooling at the tub edge where mildew starts.
Rust-resistant grommets: Rust stains permanently damage both the liner and the decorative curtain behind it - metal grommets are worth the small premium over plastic rings.
Size fit: Standard tub/shower combos need 70x72 or 72x72 inches; stall showers need 54x78 inches; extra-tall configurations need 72x78 inches. Measure before ordering.
Machine washability: Fabric liners require monthly machine washing; most PEVA liners tolerate gentle cold-water machine washing as well - check before buying.
Antimicrobial treatment: Built-in mildewcide additives in the PEVA compound outperform spray-on surface treatments - look for this feature in premium liners like Epica.
Replacement economics: A $7.92 liner replaced every 6 months costs $15.84 per year; a $16.99 8G liner lasting 12+ months costs less and generates less plastic waste.

What is the most eco-friendly shower curtain liner?

The most eco-friendly shower curtain liner in 2026 is a machine-washable fabric option like the Zenna Home Microfiber Liner at $9.39, because it lasts 2–3 years with monthly washing and generates less plastic waste than annual plastic liner replacements. For plastic liners, EVA (ethylene vinyl acetate) produces fewer chemical emissions than PEVA during manufacturing and off-gassing and is BPA-free and PVC-free - the top choice for chemically sensitive households. Among the PEVA liners on this list, the LiBa PEVA 8G and Amazon Basics 8G are both PVC-free and chlorine-free - a significant improvement over traditional vinyl liners that release harmful VOCs in enclosed bathroom spaces ^[2].

Frequently Asked Questions About Shower Curtain Liners#

Frequently Asked Questions

How often should you replace a shower curtain liner?

Replace a plastic PEVA liner every 6–12 months depending on gauge thickness and shower frequency. 8-gauge liners (LiBa PEVA 8G, Amazon Basics 8G) last up to 12 months in typical daily-use bathrooms; lighter-gauge liners may show mildew or discoloration in as little as 3–6 months. Machine-washable fabric liners like the Zenna Home microfiber liner last 2–3 years with monthly washing, making them the better long-term value despite higher active maintenance requirements.

What is the best material for a mildew-resistant shower curtain liner?

PEVA (polyethylene vinyl acetate) is the best material for most households - it resists mildew, releases far fewer VOCs than PVC, and is available in gauges up to 8G. EVA (ethylene vinyl acetate) is the safest option for chemically sensitive households because it produces fewer emissions during manufacturing. Machine-washable microfiber fabric is best for buyers who prefer a soft, non-plastic feel and are willing to wash the liner monthly to prevent mildew accumulation.

What is PEVA and is it safe for shower curtain liners?

PEVA (polyethylene vinyl acetate) is a PVC-free plastic compound used in shower liners, food storage bags, and medical devices. It is significantly safer than traditional PVC because it does not require phthalate plasticizers and does not release chlorine-based VOCs. Good Housekeeping's Cleaning Lab consistently rates PEVA liners as the safest plastic liner option for enclosed bathroom spaces, and it is the material used in the majority of liners on this list.

Are fabric shower curtain liners better than plastic for preventing mildew?

It depends on your bathroom's ventilation. In well-ventilated bathrooms, machine-washable fabric liners last longer and prevent mildew effectively with monthly washing - and they last 2–3 years versus 6–12 months for plastic liners. In poorly ventilated bathrooms, Wirecutter recommends plastic PEVA liners specifically because they drip-dry in under two hours, while damp fabric can harbor mildew overnight in stagnant air. Assess your ventilation honestly before choosing.

Can you put a plastic shower curtain liner in the washing machine?

Most PEVA liners tolerate gentle machine washing on a cold or warm cycle - do not use hot water or a high-heat dryer cycle, which can warp or shrink the liner. Add a few towels to the load to cushion the liner during the spin cycle and prevent it from clumping. Wash monthly to remove soap scum and surface mildew before it becomes visible or penetrates the material.

What does gauge mean for shower curtain liners - does a higher gauge really matter?

Gauge (G) measures the thickness of a plastic liner. An 8-gauge liner is noticeably heavier and thicker than a 4-gauge liner. Bob Vila's testing found that 8G PEVA liners outlasted 4G versions by an average of 4–6 months before showing visible mildew or discoloration in humid bathroom conditions. Higher gauge also means the liner drapes more flatly against the tub, reducing the moisture pooling that feeds mildew growth along the bottom edge.

How do I remove mildew from a shower curtain liner without bleach?

Mix equal parts white vinegar and water, apply to mildewed areas, let sit 30 minutes, scrub with a soft brush, and rinse. For machine-washable liners, add 1/2 cup of white vinegar to the wash cycle with your regular detergent. Baking soda paste (baking soda mixed with a small amount of dish soap) also removes surface mildew without the material degradation that repeated bleach exposure causes on PEVA liners.

What size shower curtain liner do I need for a standard bathtub?

Standard bathtub/shower combos require a 70x72 or 72x72 inch liner. Stall showers (typically 36 inches wide) need a 54x78 inch liner. Walk-in showers and extra-tall configurations may need 72x78 inches or custom sizing. Always measure your shower opening before ordering - the majority of liner returns are due to incorrect sizing, and most retailers do not accept returns on opened bath products.

Do shower curtain liners with magnets actually work?

Yes - bottom magnets are one of the most practical and effective features in a shower curtain liner. During showering, the Bernoulli effect (water pressure differential between the inside and outside of the shower stream) pulls the liner inward. Weighted magnets counteract this by adhering to the metal or acrylic tub surface, keeping the liner flat against the tub edge and preventing water from escaping around the liner's bottom edge into the bathroom floor.

What is the difference between EVA and PEVA shower curtain liners?

Both EVA and PEVA are PVC-free plastic compounds safe for shower liner use. EVA (ethylene vinyl acetate) produces fewer chemical emissions during manufacturing and off-gassing - it is the preferred choice for chemically sensitive individuals and households with infants or toddlers. PEVA (polyethylene vinyl acetate) is more widely available, typically less expensive, and equally mildew-resistant in standard bathroom conditions. Both are far safer than traditional PVC liners.

Do I need a liner if my shower curtain is already waterproof fabric?

Most waterproof fabric shower curtains still benefit significantly from a separate liner. Fabric waterproofing coatings degrade over time and often do not prevent all water escape - particularly at the bottom edge where a liner's weighted magnets provide a physical seal against the tub. A $7.92 PEVA liner behind a waterproof fabric curtain protects the outer curtain from direct mildew exposure and water contact, extending the expensive curtain's life by years.

How do I prevent my shower curtain liner from getting moldy between washes?

Spread the liner fully open after every shower so it air-dries completely - this is the single most effective step regardless of liner material. Additional measures: run your bathroom exhaust fan for 20–30 minutes after showering, wipe the bottom magnets and tub edge dry weekly, wash the liner monthly in warm water with white vinegar, and consider rotating between two liners (like the iDesign 2-pack) so each dries completely before reuse.

Is EVA or PEVA better for the environment in shower curtain liners?

EVA is generally the more environmentally friendly choice - it produces fewer chemical emissions during manufacturing and emits lower VOC levels when new. Both EVA and PEVA are significantly more sustainable than PVC. For the lowest environmental impact overall, a machine-washable fabric liner that lasts 2–3 years generates less cumulative plastic waste than annual plastic liner replacement, regardless of whether the plastic is EVA or PEVA.
