Freeze-thaw cycling is the governing condition. Water that gets into masonry, grout or a roof detail expands when it freezes and widens the gap it entered through.
Waterproofing is the whole job. Tile is a wear surface, not a water barrier - what keeps water out of the framing is the membrane behind it, and a shower built without a proper pan and bonded membrane will rot the subfloor whatever it looks like.
Tub-to-shower conversions are the most requested change and the most commonly botched, usually at the curb and the drain: the pan has to slope to the drain evenly or water sits against the curb and finds the gap.

What the job includes
- Tub-to-shower conversion
- Waterproof pan and membrane systems
- Tile shower and wet-room builds
- Vanity, toilet and fixture replacement
- Exhaust ventilation sized and ducted
- Grab bars and accessible layouts
