Shower Niche: What Homeowners Need to Know Before Building One

A shower niche is a recessed shelf built into a shower wall that provides storage for shampoo, soap, razors, and other bathing products without requiring a separate freestanding caddy or protruding shelf. The niche is framed between studs during rough construction, waterproofed as part of the shower system, and tiled to match or complement the surrounding shower walls.

Shower niches are one of the most requested features in Phoenix bathroom remodels. They look clean, function well, and eliminate the visual clutter of wire racks hanging from showerheads. They also require more technical care to build correctly than they appear, because any niche in a shower wall is a potential waterproofing vulnerability if not executed properly.

At Phoenix Home Remodeling, niches are planned during the design phase so they land between existing studs without requiring structural modification, and waterproofed during the shower membrane phase before any tile is installed.

A niche creates an inside corner on five planes, the back wall, two side walls, the top, and the bottom, and each of those transitions must be fully waterproofed and reinforced. The niche is also a horizontal surface where water can pool if the floor of the niche does not have a slight slope toward the shower. Niches that are not waterproofed correctly, or where the bottom is flat rather than slightly sloped, become areas of chronic moisture accumulation that lead to grout failure, mold growth, and eventually structural damage behind the wall.

Location: Best placed on a non-exterior wall to avoid insulation and vapor barrier complications. Should be positioned at a convenient reach height, typically between 48 and 60 inches from the floor. Multiple niches or a full-height niche tower are available in larger showers.

Width: Standard niche width is determined by stud spacing. Between two studs at 16 inches on center, the rough opening is approximately 14 inches, yielding a finished niche of about 12 inches wide. Wider niches require structural header work.

Tile selection: Niches can be tiled in the same tile as the surrounding wall or accented with a different material such as a mosaic insert or contrasting stone. The inside corners require careful tile cutting and proper grout joint management.

Shelf vs. open niche: A single-level niche is the most common. Multiple shelves can be added, either tiled in place or with glass shelves added after tiling. Glass shelves in niches require pre-planned anchor points.

Waterproofing: All five planes of the niche interior must be waterproofed as part of the shower membrane system, with reinforcing tape at all inside corners. The niche floor should be sloped 1/8 inch per foot toward the shower to promote drainage.

Not without removing tile. A niche must be built into the shower framing before the waterproofing membrane is applied and tiled. There is no retrofit option that maintains the integrity of the waterproofing system. This is why niche location, size, and quantity need to be confirmed during the design phase, before construction begins.

Not always. Exterior walls present challenges because the niche cuts into the insulation cavity and may require vapor barrier modifications. Walls that contain plumbing or electrical runs may not have enough clear space between studs for a niche. Our feasibility assessment identifies any constraints on niche placement before design locks in a location that cannot be executed.

We plan niche location and size during the design phase. During construction, niches are framed, waterproofed with the rest of the shower system using reinforced transitions at all inside corners, and tiled by our tile specialists. The niche floor is always sloped to drain. We treat niche waterproofing with the same care as the shower floor, because failures in either location produce the same type of structural damage.

• Where is the niche located relative to stud layout and is the planned width achievable without a header?
• Is the niche on an interior or exterior wall?
• How will the niche be waterproofed and how will inside corners be handled?
• Will the niche floor be sloped and by how much?
• What tile are you recommending for the niche interior?
