Styles & brands we work with







Bathroom Remodeling Contractor in Walnut Creek
A Bathroom Remodeling Contractor in Walnut Creek does more than swap out tile and fixtures – the real work is what you can’t see. In this city’s housing stock, especially homes built from the 1960s through the 1980s, that means checking cast-iron drain lines, verifying vent fan CFM, and repairing subfloor rot before new finishes go down. We act as the general contractor on the job: we pull permits, coordinate plumbing and electrical rough-in, schedule inspections, and manage the finish trades.
Full Bathroom Remodeling
We tear out to the studs where needed, replace or re-route plumbing, update electrical to code, install new waterproofing and tile, and set vanities, fixtures, and glass. For Walnut Creek homes this often includes adding an appropriately sized exhaust fan – many original baths vent into the attic or not at all. A full remodel runs $9,000 – $28,000.
Small Bathroom Remodels
Guest baths and half baths in Walnut Creek condos and older ranchers can often be refreshed without moving plumbing. New vanity, lighting, toilet, tile, and trim. $5,000 – $12,000 depending on material grade.
Vanities, Tile, and Fixtures
We install vanities from $800 – $3,000, and tile work is quoted by the square foot after we’ve measured and verified the substrate. Glass shower enclosures are measured after tile is set to avoid gaps.
Walk In Shower in Walnut Creek

A Walk In Shower in Walnut Creek makes sense for homeowners who want to age in place, eliminate a bathtub they never use, or simply open up a small bathroom visually. We build curbless entries, low-threshold pans, and full-frameless glass enclosures. Walk-in shower installation runs $4,500 – $12,000. Tub-to-shower conversion runs $3,500 – $10,000. Shower replacement (new pan, valve, tile, and glass) runs $3,000 – $8,500.
Walk-In Shower Installation
We install proper sloped pans, waterproofing membrane up the walls, and either framed or frameless glass to suit the opening. In Walnut Creek’s older homes, we often find inadequate joist spacing once the old tub comes out. We address that during framing, not after tile is set.
Tub-to-Shower Conversion
For a homeowner who wants a seated shower or a low step-in entry, we remove the tub, re-route the drain to a 2-inch line (required by California plumbing code for showers), install a new valve and waterproofing, and finish with tile or a solid-surface surround. This is one of our most common projects in Walnut Creek.
Trusted Brands We Service in Walnut Creek
We work with specification-grade materials so Walnut Creek homeowners get professional products, not whatever’s left on a big-box shelf. We stock and install cabinetry from KraftMaid and Wellborn, surfaces from Cambria and Silestone, and fixtures from Kohler, Moen, and Toto. When you choose a specific finish, we verify availability and lock the pricing in writing as part of your allowance schedule. We also stay current on newer building performance brands like Abodu and Dvele for homeowners considering broader upgrades – we can speak to what those systems cost and whether they’re the right fit for a Walnut Creek home.
Common Bathroom Remodeling Problems We See in Walnut Creek Homes
Here’s what we keep finding behind the tile in Walnut Creek, and it’s rarely what the homeowner expected.
- Permit skips that backfire. We have seen homeowners waive a permit to “save time,” then fail a rough-in inspection when a buyer’s home inspector later flags unpermitted work. Then walls come back down to expose plumbing and wiring that should have been signed off before drywall. We pull permits on every job where the scope requires it.
- Failed cast-iron drains. Homes built in the 1970s and early 1980s across Walnut Creek – especially in neighborhoods like Rudgear Estates and Walnut Heights – often still have original cast-iron under the slab. We regularly find hairline cracks that only leak under load. A true remodel includes scoping and replacing those lines, not just covering them up.
- Rotted subfloor under shower pans. A failed shower pan on the second floor of an older home can rot the plywood before you ever see a water stain. By the time we open it up, the job is no longer just tile. It’s framing, subfloor, and waterproofing rebuilt in sequence.
- Allowance blowouts without signed change orders. A homeowner picks a Cambria slab or a frameless glass enclosure mid-project, and the final bill lands well past the original number. That’s avoidable. We lock allowances in writing at contract signing, and any change is a signed change order before work proceeds.
