Bathroom Remodelers in East Bay, CA

This is every bathroom remodeler in our East Bay directory, from Oakland and Berkeley out through Fremont and the inland valleys.

The rest are sorted by profile completeness.

What a bathroom remodel costs in the East Bay

East Bay bathrooms come with East Bay houses, and a lot of those houses are old. A 1920s bungalow in Berkeley or Oakland can hide galvanized supply lines and a cast iron drain stack that crumbles the moment someone touches it. Good remodelers here budget for surprises behind the wall, and you should too.

Rough guardrails: a refresh with new vanity, fixtures, and paint often runs $10,000 to $18,000. A full remodel with new tile and a rebuilt shower typically lands between $28,000 and $55,000. Gut renovations that move plumbing or rework the layout can pass $70,000, and hillside homes with tricky access add their own tax. These are calibration numbers, not quotes.

Questions worth asking a bathroom remodeler

Ask what happens when they open the wall and find plumbing that needs replacing, because in older East Bay housing stock they probably will. Get the change-order process in writing before anyone swings a hammer. Ask who does the waterproofing and what system goes behind the tile. And ask for a bathroom they finished at least two years ago. Anyone’s work looks good the month it’s done.

Common questions

What license should a bathroom remodeler have in California?

Either a B General Building license or the B-2 Residential Remodeling license that CSLB added for exactly this kind of work. Both appear on our listings, and you can verify any number directly with the CSLB.

Do I need a permit?

Almost always, once plumbing or electrical moves. Each East Bay city runs its own permit desk and some are slower than others, so ask your contractor how they handle the wait. A contractor who handles permits without being asked is the kind you want.

How long does a bathroom remodel take?

A straightforward one runs two to four weeks once work starts. Custom tile, glass lead times, and permit inspections stretch it. If it’s your only bathroom, ask for the no-shower days up front and plan around them.
