simplehuman Adjustable Shower Caddy, Stainless Steel and Anodized Aluminum

Why it's worth it

The simplehuman uses stainless steel and anodized aluminum, so there's no plating to chip and start a rust spot. Its shelves move up, down and sideways, which is what finally makes room for the oversized shampoo bottles that defeat most hook caddies.

It's built from materials that don't need a coating to survive. Stainless steel and anodized aluminum both form a hard oxide skin that water can't get through, and that skin repairs itself when it's scratched. That's a real difference from a chrome-plated caddy, where the protection is a thin layer over ordinary steel. Chip it once and rust starts underneath. Nothing about this caddy depends on a finish staying perfect.

The shelves actually move, and that's the whole reason it works. You turn a dial and slide a shelf up, down or sideways. If you buy the giant Costco conditioner, you widen one compartment and it sits flat instead of leaning against the bar. Owners who use salon-size and warehouse-size bottles consistently call this out as the thing that sold them. Fixed-shelf caddies force you to shop around the caddy instead.
