Bathroom remodeling that holds up behind the tile
Most bathroom failures start with what you cannot see. We rebuild the substrate, waterproofing, and drainage properly, then finish it well.
Overview
Rebuild a bathroom so the waterproofing, ventilation, and drainage are right — not just the tile that sits on top of them.
What sits behind a bathroom renovation
The finishes are the part you see. The part that determines whether the room lasts is underneath: substrate, waterproof membrane, fall to the drain, and ventilation sized for the space.

What you get
Waterproofing done as a system
Substrate, membrane, slope, and drain treated as one assembly rather than separate steps, because that is how water finds a way through.
Ventilation sized for the room
Extraction matched to the room volume and ducted outside — not into a roof space where the moisture simply relocates.
