What we find in Berkeley bathrooms
Many Berkeley homes are brown-shingle and Craftsman houses with small, character-filled bathrooms: original hex or subway tile, pedestal sinks, clawfoot tubs and redwood framing. Owners usually want the bathroom to work like a new one without losing what makes the house feel like itself.
We bring the plumbing, waterproofing and ventilation fully up to date behind the walls and choose finishes that suit the age of the house. Older raised foundations make it practical to reroute drains from the crawlspace.
Drag to See the Difference
One bathroom in Sacramento, CA — our own photographs, not a supplier's catalogue. Drag the handle, or use the arrow keys.



The part you never see again
Stripped to the studs, re-plumbed, waterproofed, then tiled in large-format porcelain with a hex mosaic floor, a recessed niche and a bench.
The middle photograph is the one that matters. Once tile goes on, nobody can check whether the framing was sound, the pipes were replaced or the waterproofing was done properly — which is exactly why a bathroom that was tiled over bad work starts failing in a couple of years.
One contract for the whole bathroom
Demolition & prep
Protection for the rest of the house, removal of the old room, and repair of any rot or damaged subfloor we find.
Plumbing & valves
New supply and drain lines where needed, a pressure-balanced shower valve and water-efficient fixtures.
Waterproofing
A continuous waterproof membrane behind and under every tiled shower — the part you never see and the reason it lasts.
Tile & finishes
Floor and wall tile, niches and benches, vanity and counter, mirror, glass and accessories.
Electrical & fan
GFCI-protected outlets, layered lighting and an exhaust fan ducted to the outside with humidity control.
Powder rooms
Half baths and powder rooms too — a quick, high-impact project in its own right.
Permits and inspections, handled
Bathroom permits in Berkeley are issued by Berkeley’s Building & Safety Division. We prepare the application (filed through the Permits Online portal), schedule the inspections and meet the inspector on site.
When a permitted remodel touches them, California also requires a few upgrades that we build in from the start:
- Water-conserving toilets, showerheads and faucets
- GFCI protection for bathroom outlets
- An exhaust fan ducted outside, with humidity control
- Working smoke and carbon-monoxide alarms, which the inspector checks

Bathroom Remodeling in Berkeley: FAQ
Do I need a permit to remodel a bathroom in Berkeley?
Usually, yes. In California a permit is normally required when a remodel moves or replaces plumbing, changes electrical circuits or alters walls; purely cosmetic work often is not. In Berkeley permits are issued by Berkeley’s Building & Safety Division. We confirm what your project needs at the site visit, prepare the application and handle the inspections.
How long does a bathroom remodel take in Berkeley?
It depends on the scope and on permit timing. Permit review usually takes a few weeks; once materials are on site, the construction itself typically takes a few weeks for a full bathroom. You get a written schedule with your proposal, and one project manager keeps you updated throughout.
Do you remodel powder rooms and half baths too?
Yes. Powder rooms and half baths are some of our favorite projects — new vanity, toilet, lighting, tile and paint can transform a small room quickly. If you want to turn a half bath into a three-quarter bath with a shower, we check whether the plumbing route makes that practical.
How much does a bathroom remodel cost in Berkeley?
Every bathroom is priced from what we see on site: the size of the room, whether plumbing moves, the finishes you choose and what we find behind the walls. We give you a written, fixed price after a free visit — or often from photos you send with the form above — rather than a ballpark range.
Which parts of Berkeley do you work in?
All of Berkeley, including Elmwood, Rockridge, North Berkeley, Claremont. If you are not sure whether we cover your street, send your address with the form and we will confirm.
