Are adhesive shower caddies or tension-pole caddies better?

It depends on your wall surface and how much you store. Adhesive shelf sets install without drilling and suit smooth tile, and the most-reviewed options here have tens of thousands of ratings. Tension-pole corner units hold far more and don't rely on adhesive bonding, but they require a floor-to-ceiling fit and reviewers occasionally note slipping over time. Neither is universally superior.
