The waterproofing you never see
Sheet or liquid membranes, pre-sloped pans, seam banding, and proper curb detailing are where a bathroom either lasts twenty years or rots the subfloor. We do not shortcut this layer.

Bathroom remodeling
Waterproofed properly, finished beautifully
Primary suites, hall baths, and powder rooms: curbless and tiled showers, floating vanities, heated floors, new plumbing fixtures, and ventilation done right.
What's included
- Full waterproofing assemblies and pan slopes
- Large-format tile and niche detailing
- Heated floor systems
- Correctly sized and ducted exhaust fans
Ventilation is part of the remodel
An undersized or unducted fan puts moisture back into your framing. Every Trinity bath gets a correctly sized, correctly vented fan on a timer or humidity sensor.
