Frequently Asked Questions

Are floating shelves waterproof enough for a shower?

Depends entirely on material — solid wood or MDF shelves swell, warp, or delaminate in constant humidity and direct spray, while non-porous materials like aluminum don't absorb water and are built for wet bathroom environments. DecoTeak's floating shelves are aluminum for this reason.

Does aluminum rust in the shower?

No — aluminum doesn't rust like steel or iron; it forms a thin, self-repairing oxide layer that blocks further oxidation on contact with water. It can pit under harsh chlorine-based cleaners, so mild soap and water is the safer cleaning choice.

How much weight can a floating shelf hold?

Rated capacity assumes the recommended mounting method — a shelf anchored into studs holds meaningfully more than the same shelf on drywall anchors or adhesive alone, so the listed weight limit isn't a worst-case-wall number. Check the individual product spec for the exact rating.

Can you install a floating shelf on tile without drilling?

Adhesive strips and suction mounts exist but carry real, low weight limits — fine for a dry loofah, not reliable for shampoo bottles. Drilling with a tile or masonry bit and anchors rated for the wall behind the tile is the standard method for anything that needs to hold real weight.

Do floating shelves need to hit a stud?

Not necessarily — anchors rated for drywall or tile-over-cement-board can carry a load, but studs, or wall-rated anchors, give more margin for heavier or repeatedly loaded items.

Will a metal shelf get moldy or hold soap scum?

A non-porous aluminum shelf doesn't absorb water or feed mold growth into the material itself — buildup stays surface-level soap scum or mineral deposits, removable by wiping — unlike a wood or MDF shelf, where trapped moisture can grow mold within the material.
