In stockHow much you need depends on the room, and what it costs to fit depends on what is behind the wall. Build the list here and send it for a quote — we check the amounts against the room and price the materials and the work together.
A prefabricated niche gives a square, waterproof-ready recess without building one from board and hoping the corners stay true.
Position matters more than size. A niche should align with a horizontal grout line and sit between studs, which usually means deciding its location during framing rather than during tiling.
Goes with it
The parts of the assembly this material depends on. Ordering them together avoids the mid-project discovery that the mortar is wrong for the format.
Seen in
Each room says which surface this material went on there, and lists everything that went in alongside it, so you can see it in the position you are considering and order the whole assembly rather than assembling it yourself.
