Bathroom Remodeling in Miami

A bathroom rarely fails at the surface. It fails behind it — at a shower pan that was not sloped to the drain, at a corner where the waterproofing membrane stopped short, at a niche cut into a wall without the substrate being detailed first. Tile and grout are not waterproof and were never meant to be; they are a wearing surface over a system that is.

None of this is visible on the day it is finished. It shows up a year or three later as a soft spot in the floor outside the shower, or a stain on the ceiling below. By then the fix is the whole room again.

Wet areas get moisture-resistant substrate rather than standard board, a waterproofing membrane behind the tile, and a pan sloped properly to the drain. Niches and benches get detailed as part of the waterproofing rather than cut in afterwards. Changes of plane — floor to wall, wall to ceiling — get treated as the joints they are.

It is unglamorous work that nobody photographs, and it is the whole difference between a bathroom that lasts and one that looks finished.

A South Florida bathroom needs a working exhaust fan, and it needs to discharge outside the building. A fan that dumps into the attic is moving the moisture problem rather than solving it, and in this climate an attic is the worst place to put it.

Slab-on-grade construction shapes the plumbing too. There are no basements here, so drain lines run in or under the slab — which means moving a toilet or a shower drain is concrete work, not a morning with a saw. It is worth knowing that before the layout is settled.
