Triangular shelves are the reason this set works where rectangular caddies do not: each unit tucks into the corner of a shower and uses space that was already wasted. You get two of them, each 10 by 17.5 by 26.5 inches with three shelves and raised baffles so bottles do not slide off when knocked. Each shelf carries 18 lbs and drainage holes stop water pooling around the bases. Polypropylene throughout means nothing rusts, and the pair weighs 4.5 lbs in total. Every stand can also be split into a single shelf and a 2-tier shelf, so one part sits on a countertop while the other stays under the sink. Assembly needs no tools. In white the stands blend into a tiled shower wall rather than standing out as extra clutter.
