Why Accurate Shower Niche Size Matters

Shower niches built to tile dimensions avoid cuts and look professional. Standard stud spacing (16" O.C.) accommodates most layouts. Proper sizing prevents water accumulation and difficult installations.

Common Mistakes to Avoid

Building niche before choosing tile, not waterproofing properly, insufficient slope for drainage, placing too low (water spray issues), and forgetting stud spacing constraints.
