This rustproof anodized aluminum pole caddy fits into a shower corner and extends from 5 to 9 feet. This caddy is sturdy and easy to install, with a single connection that locks it into place.
The four shelves hold a lot of gear, and are removable, which makes cleaning a lot easier. The shelves also have holes so you can store bottles upside down. This caddy does not come cheap, but it carries a lifetime guarantee against rust or breakage.
Reviewers say it is “an outstanding product in every way,” and “the installation requires no tools.”
