Did we do this walk-in shower right? Look at what happens BEFORE the tile.

1) Sloped mud base + cement board + full red waterproofing membrane — moisture can’t get into the wall, so mold has nowhere to start.

2) Niche and bench built INTO the wall, sealed with the waterproofing — not dropped in later.

3) Only after waterproofing passes do the big stone-look slabs go up — fewer grout lines, easier to clean.

4) The finished result: frameless walk-in, rainfall plus handheld on a thermostatic valve, a blue-gray marble bench, and a pebble floor.

5) A 72-inch double-sink white shaker vanity, arched backlit mirrors, a smart toilet, and a pocket door to save space.

This bathroom in Waltham, MA was taken down to the studs and rebuilt — the part that decides how long it lasts is the part you never see.
