Fast, Reliable Bathroom Remodeling Across Saranap
A full bathroom remodel in Saranap typically runs $9,000 to $28,000, depending on the scope of the job, the age of your framing, and whether you’re keeping the existing footprint or moving walls. Most Saranap homes we work on were built between 1945 and 1965, which almost always means we’re opening up more than expected once the old tile comes down. That’s not a problem if it’s priced into the plan before demo day. Call (936) 259-2607 and we’ll give you a written number before any work starts, not after.
We know this area’s quirks. Saranap sits unincorporated, which changes who reviews your permits, how long the inspections take, and which contractor is actually set up to handle it correctly. We have been through the Contra Costa County process enough times that it doesn’t slow us down. You shouldn’t have to learn county permitting on your own bathroom project.
Why Penhallow Remodeling Is Saranap’s Preferred Bathroom Remodeling Company
Trevor Nash leads our team, and he’s the person who makes sure the written price and the written guarantee both mean something. That’s the Kingswell Way, the operating standard behind every Penhallow job since 2004. We put the number on paper before a single cabinet is pulled or tile is set. If the work fails inside the 365-Day Done Right Promise window, we come back and fix it at no charge. That’s in writing, on every project.
Saranap homeowners call us because they’ve been burned before. A verbal estimate that changed at the door. A crew that never showed. A shower pan that cracked six weeks after the final check cleared. We answer the phone with a live person 24/7, we send background-checked, uniformed technicians, and we don’t leave a job until county inspection signs off. Your address isn’t in Lafayette or Walnut Creek, and we never pretend otherwise.
Shower Remodel in Saranap
Shower Remodel work in Saranap usually starts because the original 1950s or early 1960s tile has finally failed at the grout lines, or because water has been seeping into the subfloor for years and the pan won’t hold. In a Saranap house, that often means post-and-pier construction underneath, which changes how we slope the drain and support the pan. A shower replacement here typically runs $3,000 to $8,500. A full walk-in shower installation, with new waterproofing, valve, and tile, lands between $4,500 and $12,000.
Waterproofing and framing correction
Before any tile goes up, we check what’s behind it. On mid-century homes, that’s often original drywall or mortar bed, not cement board substrate (the moisture-resistant layer behind your tile). We strip to the studs, sister or brace anything that’s sagging, and rebuild the wet area so the new tile actually stays put.
Valve and trim selection
We carry and install Kohler, Moen, and Delta valves and trim. You pick the finish, we rough in the valve to spec, and the trim lands after tile. No mismatched handle sets. No surprise valve swap mid-job that changes the finish you already paid for.
Tub to Shower Conversion in Saranap
Tub to Shower Conversion in Saranap is one of the most common requests we get, especially in the ranch and cottage floor plans built between 1945 and 1965. Homeowners want a walk-in shower without a curb, a bench, or a handheld slide bar, and the old cast-iron tub is usually too far gone to refinish. This conversion typically runs $3,500 to $10,000 in Saranap, depending on drain relocation and whether we find rot in the subfloor under the tub.
Drain relocation and subfloor repair
The tub drain rarely lines up with the new shower drain. On a post-and-pier foundation, that means carefully notching joists, re-running the trap, and checking slope before we close anything up. If the subfloor has water damage, we sister the joists and lay new plywood before the pan goes in.
Low-threshold and curbless options
Many Saranap homeowners want a low-threshold shower for aging in place. That decision affects the floor height of the whole bathroom. We scope that before quoting, not after the curb is already poured, so the written price reflects the actual job.
Trusted Brands We Service in Saranap
We install materials from recognized trade brands, not whatever was on sale at the supplier. You’ll see Cambria, Silestone, and Caesarstone countertops in our vanities. Kohler and Moen valves and trim in our showers. KraftMaid and Wellborn cabinetry when you want a new vanity that matches the rest of the house. Products like ADU and Cover are worth knowing about if your Saranap remodel includes an attached addition, but for a bathroom, the brands behind the water and the stone matter most. We stock common Saranap-sized parts locally so we’re not waiting on a three-week ship for a standard valve cartridge.
Common Bathroom Remodeling Problems We See in Saranap Homes
- County permit confusion: A contractor who assumes Saranap is Lafayette or Walnut Creek pulls the wrong permit and the job gets red-tagged. We file through Contra Costa County’s Department of Conservation and Development from the start, so demo doesn’t stall waiting on the right inspector.
- Post-and-pier framing surprises: Under the old tile, we often find sagging joists or dry-rotted subfloor. On a post-and-pier foundation, that subfloor carries more load than it would on slab. We write the change order before touching framing, not after.
- Undersized electrical panels: A 1950s panel often can’t handle a modern bathroom’s GFCI circuits, heated floor, or vent fan. We plan for the panel work up front so the bathroom doesn’t trip the breaker the first week you use it.
- Stock shower kits that don’t fit: Mid-century bathrooms have irregular framing. A stock shower kit specified without checking the rough opening usually ends up sitting crooked with gaps the tile can’t hide. We measure the actual opening and order the pan and glass to fit.

FAQs About Bathroom Remodeling in Saranap
Neither. Saranap is unincorporated Contra Costa County, so your bathroom remodel permit goes through the County’s Department of Conservation and Development, not any city building department. That means a different portal, a different inspector pool, and different processing timelines than your neighbors in Lafayette or Walnut Creek. We handle that filing for you as part of the project, so the permit is in the right system from day one. If you want to talk through what that looks like for your address, call (936) 259-2607.
It means there’s a real chance we open the walls and find the original subfloor, undersized electrical, or post-and-pier framing that needs reinforcement. On a ranch or cottage from that era, a bathroom remodel often includes sistering joists, replacing the subfloor under the tub or shower, and pulling a new circuit for the vent fan and GFCI outlets. That’s not a surprise if it’s scoped before demo. We write the change order before touching framing, so you know the number before we swing a hammer. Call (936) 259-2607 and we’ll walk your specific house.
We install Kohler, Moen, and Delta valves and trim, and we work with tile from local suppliers who stock what Saranap homes actually use. Cambria, Silestone, and Caesarstone are the main countertop lines for vanity tops. You pick the finish and the stone. We handle the rough-in and the waterproofing so the brands we install are backed by the same written guarantee as the labor. Call (936) 259-2607 to talk through what you want.
Parts of Saranap fall within State Responsibility Area fire hazard severity zones, which triggers California’s Chapter 7A ignition-resistant construction standards for new builds and substantial additions. A bathroom remodel inside the existing footprint rarely triggers Chapter 7A on its own. But if your project expands the home’s exterior footprint, it can. We check the overlay before we quote, so you’re not surprised by an ignition-resistant vent or assembly requirement mid-job. Call (936) 259-2607 and we’ll check your parcel.
It mostly affects custom-order items: a special vanity, a non-stock tile, a glass enclosure cut after the tile is set. Saranap is inland from the major showrooms, so deliveries get scheduled around what’s already in the supply chain. We stage materials before demo day whenever possible, and we stock common valve cartridges and trim parts locally so a mid-job swap doesn’t stall the rough-in. If timing matters to you, call (936) 259-2607 and we’ll lay out the schedule in writing.
