Every bathroom job runs through the same waterproofing and plumbing questions — the difference is how much of the room changes around them.
Get an EstimateNew vanity, fixtures, tile, and paint within the existing layout. Plumbing stays where it is, so the work moves fast.
Moving the toilet, shower, or vanity means relocating drain and supply lines — and re-waterproofing the shower pan and walls from scratch.
Older SF buildings often hide subfloor rot or outdated drain lines under the tile. A full gut means addressing that before anything new goes in.
Disclosed timeline. Sign-off at every milestone. No surprises.
We check what's under the existing tile and fixtures before committing to a scope.
A written estimate and scope of work, including any plumbing relocation.
Plumbing and any structural changes are submitted before demo starts.
Demo, rough-in, waterproofing, then tile and finishes — in that order, no shortcuts.
"Saw this construction company office in my neighborhood and decided to talk with them about remodeling my bathroom. They were amazing, were up front about timelines, costs, and what to expect overall. They delivered on every one. I would highly recommend!"

A bathroom remodel typically runs $35,000–$120,000 depending on scope — a refresh at the lower end, a full gut with waterproofing and plumbing relocation at the higher end.
A cosmetic refresh often doesn't require a permit. Moving plumbing, fixtures, or walls does — we handle the SF DBI submission as part of the project.
A refresh can take 2–4 weeks. A reconfiguration or full gut with waterproofing and permitting typically runs 2–4 months from design through completion.
