Niches, benches and shower storage that stay watertight
Last updated
Short answer
A niche and a bench are both holes cut in a waterproofed wall, so both live or die on detailing. Put the niche out of the direct spray, slope its sill so water runs out, align it with the tile layout, and waterproof every inside corner before tile. A bench needs a solid substrate, a slight slope, and full membrane coverage under the tile.
Key takeaways
- Place the niche on a dry wall or beside the valve, not directly under the head.
- Slope the niche sill toward the shower so water leaves rather than pools.
- Set niche size to whole tiles where possible; the layout looks intentional.
- A bench must slope about a quarter inch per foot and be fully waterproofed.
- Grab-bar blocking goes in at the same time, even if bars are added later.
Getting the niche right
- Height: around chest level for the main niche, lower for a foot ledge
- Position: between studs, out of the direct spray path
- Sill: sloped and tiled in one piece where possible to reduce joints
- Layout: sized to full tiles so grout lines run through cleanly
- Waterproofing: preformed niche or fully detailed corners, no exceptions
Benches and foot ledges
A full bench is roughly 17 to 19 inches high and 15 inches deep, which is comfortable to sit on and useful for anyone who needs to. A corner foot ledge is far smaller and solves shaving without eating the shower. Both need a rigid substrate, a slope so water runs off, and continuous membrane over the top and under the tile.
A bench built on unsupported board and waterproofed only at the surface is one of the most common leak points we open up.
Storage that actually gets used
Count the bottles in your current shower before deciding niche size. Two niches, or one wide niche with a shelf, is usually more useful than a single small square. And plan a place for a razor and a washcloth that is not the floor — a small ledge beside the valve solves it.
Frequently asked questions
- Can a niche go on an exterior wall?
- It can, but insulation depth has to be considered so the niche does not create a cold spot. We prefer an interior wall when the layout allows.
- Should the niche be tiled in an accent tile?
- It is a nice touch, but more small tile means more grout in a wet area. A single slab or large-format back is easier to keep clean.
