Niches combine several board edges and inside corners in a small area. Water can sit on the bottom shelf, so the waterproof backer board layout should be reviewed before tile.<\/p>\n\n\n\n
When should niche size be confirmed?<\/h3>\n\n\n\n
Confirm niche size before the wall closes. Changing the opening later can create awkward cuts, weak edges, or rushed waterproofing details.<\/p>\n\n\n\n
What should installers photograph?<\/h3>\n\n\n\n
Photograph the back panel, side returns, bottom shelf, inside corners, and nearby valve wall before tile begins. These photos make hidden work easier to review.<\/p>\n\n\n\n
Can a niche be added late?<\/h3>\n\n\n\n
Late additions are risky because framing, board support, and tile layout may already be fixed. If possible, plan the niche before board installation.<\/p>\n\n\n\n
What should buyers ask the supplier?<\/h3>\n\n\n\n
Ask which board and auxiliary materials are appropriate for niche corners, seams, and transitions in the selected shower wall system.<\/p>\n\n\n\n
Shower Niche Takeaway<\/h2>\n\n\n\n
A niche looks small, but it concentrates many wet-wall decisions. Board support, inside corners, ledges, and tile layout should all be checked while the opening is still visible.<\/p>\n\n\n\n
For this use case, waterproof backer board is most valuable when it helps the installer create a clean, inspectable niche before the finish layer hides the details.<\/p>","protected":false},"excerpt":{"rendered":"
