Bathroom remodeling in San Jose & the Bay Area

Thumbtack's 2026 San Jose cost guide lists a typical bathroom remodel range of about $8,254 to $25,671, with some projects reported as high as about $59,343. Those figures are general averages, not quotes. Your price depends on the size of the room, whether fixtures or walls move, the finishes you choose and what is found behind the walls and under the floor, so a written proposal from R&B Master Construction Inc. comes after reviewing the space and defining the scope.

It depends on the scope. The City of San Jose lists cosmetic work such as tile with no structural change, flooring, painting and cabinet or countertop replacement as exempt from a building permit, but plumbing, electrical, mechanical and structural work need permits. Replacing bathroom fixtures in their existing locations, without changing walls or windows, may qualify for the City's online minor-remodel permit; moving fixtures or changing walls is treated as a major remodel. Verify your specific scope with the City of San Jose (or your city) building department before work starts.

There's no honest fixed answer until the scope, selections and permit path are known. As a general reference, Angi's guide says a typical bathroom remodel takes about two to three months from planning through completion, and a minor update that doesn't move plumbing or wiring can be shorter. Permit inspections, product lead times and conditions found after demolition can all extend the schedule. R&B discusses a proposed schedule once those items are defined.

Often it can, but the floor structure, drain location, waterproofing and shower enclosure need to be reviewed first. The City of San Jose's minor-remodel guide lists shower requirements such as a minimum pan area of 1,024 square inches, at least 30 inches in any direction, and a door with a 22-inch minimum clear opening. Because a conversion involves plumbing work, verify the permit path with the City of San Jose (or your city) building department. Many homeowners combine the conversion with a new vanity, counters or flooring, so mention everything you're considering at the start.

It depends on the proposal, so read the scope line by line. Some proposals include finish materials such as tile, vanity, fixtures and flooring, while others cover labor and rough materials and expect the homeowner to buy the finish selections. California requires a written contract for home improvement work over $500 that describes the work and materials, and changes should also be in writing. Before signing, ask any contractor, including R&B, to list exactly what is included, excluded and supplied by you.

A soft or sinking area near a shower, tub or toilet can be a sign of water damage to the subfloor or framing, and the full extent often isn't visible until the finish floor is removed. Have it inspected before choosing new tile or flooring, because repairs underneath change the scope and cost. The City of San Jose exempts floor sheathing repairs up to 10 square feet from a building permit, but larger repairs or framing work may need one. Verify with the City of San Jose (or your city) building department.

Yes. The City defines relocating or adding fixtures as a major remodel, which needs plans and plan review rather than a minor-remodel online permit. R&B prepares the drawings and handles the submittal.

Yes. We schedule the inspections your permit requires, including the ones that happen before walls and the shower are closed in, and we're on site for them.

Yes. Storage, fixture proportions, lighting and door placement all matter in a smaller room. Share what feels cramped or inconvenient so the project can focus on those needs.

Keeping them can simplify part of the project, but existing connections and the condition behind the finishes still need review. Mention any fixtures you would also like to retain.

Raise this at the first conversation. The construction sequence and alternative bathroom arrangements need to be discussed before work begins; availability during each stage should not be assumed.

Discuss the specific needs of the people using the room. Entry width, circulation, shower access, reachable controls and future support locations can be considered together. The design must be checked against the available space and the relevant project requirements.

Finalize the fixture models, shower layout, niches or benches, tile pattern and transitions. Coordinate the underlying surfaces, water-management details and required reviews before covering them. Tile and grout choices should be considered with the full shower or bath assembly.
