A bathroom that's waterproofed right — not just tiled prettily.

The finishes are what you see; the waterproofing, slope, and ventilation are what decide whether it lasts. We build the part behind the tile to code, then make the part you see look the way you want.

Is this you?

Your bathroom is dated, cramped, or quietly failing behind the tile. You want a walk-in shower, a better layout, or a primary suite that feels like one — done by someone who treats the waterproofing and ventilation as seriously as the finishes.

This fits if you want to:

What’s included — and what’s not

IncludedNot included
Layout, waterproofing, and finish designMoving the bathroom to a new part of the house (priced separately)
Tile, vanity, fixtures, glass, lightingHigh-end fixtures above an agreed allowance
Plumbing and electrical changes to codeWhole-home plumbing replacement
Exhaust ventilation sized and vented outStructural work beyond the agreed scope

How it works

  1. Consultation — we look at the existing bath, the moisture history, and what you want it to become.
  2. Design + selections — layout, tile, fixtures, and glass settled before demo.
  3. Permits — pulled where plumbing or electrical moves.
  4. Build — demo, waterproofing, rough-in, tile, fixtures, and glass, inspected at each stage.
  5. Walkthrough — punch list, final inspection, clean hand-back.
Behind the tile is the whole job. Most bathroom failures are water and ventilation failures — a missed pan slope, an unsealed niche, a fan that vents into the attic. We build the waterproofing and ventilation correctly first; the tile is the easy part.

Seattle & King County notes

Bathroom remodels that move plumbing or electrical pull a permit in Seattle (SDCI) and across King County (DPER) and the Eastside cities. Inspections at rough-in and final are part of the process — we schedule and pass them so you're not left chasing the city.

Common questions

If you're moving plumbing or electrical, yes — in Seattle and across King County. A like-for-like finish swap may not, but we confirm before starting.
