Waterproofing a Shower Niche
Every niche is a hole cut into a waterproof wall, which is where walk in shower installation lakewood ca nexusphiladelphia spends the most detailing time, since one recess adds five internal corners and a horizontal shelf to a Lakewood shower wall that previously had neither.
Position It Before the Board Goes Up
A niche lives between studs, so its width is fixed at fourteen and a half inches unless a stud is cut and headed off at framing. Keep it out of the wet wall carrying the valve and the supply line, and out of an exterior wall where it eats insulation. Height is at eye level for shampoo, lower if it also has to hold a foot.
Slope the Shelf
The bottom of the niche falls forward into the shower by a small amount, the same principle as the top of a curb. A flat shelf holds a puddle behind every bottle and the grout there stays permanently dark. On a tall niche with a divider, every shelf gets the same treatment rather than only the lowest one.
Preformed or Built
A preformed foam niche is bonded in, is part of the waterproofing system, and removes most of the ways this detail goes wrong. A site built one from cement board costs less and needs every internal corner reinforced by hand. On a job where the tile module has to be matched exactly, the site built version is often the only option.
Tile It Without a Cut in the Corner
Set out the niche so its interior takes full tiles or a deliberate mosaic, and so its outer edge lines up with a grout joint on the surrounding wall. A niche that floats between courses looks like an afterthought regardless of how well it is waterproofed. This is a setting out decision made before the first tile is fixed.
Finish the Edges
A mitred tile edge is the cleanest and the most fragile. A metal profile is robust and reads as trim. Either way the outer edge takes flexible caulk rather than grout, because it is a change of plane, and the same applies to the internal corners inside the recess where two tiled faces meet.
