Fast, Reliable Bathroom Remodeling Across Claremont
A full bathroom remodel in Claremont typically runs $9,000 to $28,000, depending on the size of the room, the age of the plumbing, and whether you’re keeping the existing footprint or moving walls. Homes near the Claremont Village and the Colleges tend to sit on the older side, which means we’re often working around plaster walls, cast-iron drain lines, and framing that hasn’t seen daylight in ninety years. Those jobs take longer than a gut-and-replace in a 1970s ranch off Foothill Boulevard, and we price them accordingly, in writing, before we start. Tom Barrett and his sons have been running crews across Claremont long enough to know which blocks have the troublesome clay soil and which bathrooms hide surprises behind the tile. Call (877) 610-1318 for a free estimate, and we’ll walk the room with you before we put a single number on paper.
Why Barrett & Sons Construction Is Claremont’s Preferred Bathroom Remodeling Company
We’re not a franchise outfit that sends a different crew every week. Barrett & Sons Construction has been owner-operated since 1998, and Tom’s name is on the truck, on the contract, and on the permit. When you call, a live person answers, day or night. When we quote a bathroom remodel in Claremont, the scope arrives in writing, the allowances arrive in writing, and every price change gets a written change order before work proceeds. You won’t get a surprise invoice at the end, because the allowance that isn’t on paper is a surprise waiting for a date. Ask anyone on your street, or look up Tom’s license number yourself. It’s published, along with his address. That’s how a local contractor should operate.
Claremont homeowners keep calling us because we understand the city’s building department, not just its neighborhoods. The plan-check staff north of Baseline Road cross-references Cal Fire’s hazard maps and enforces Chapter 7A of the California Building Code on major remodels. That’s a regulatory reality that doesn’t exist in Pomona or Ontario, and a contractor who doesn’t know it will get a correction notice before the first nail is driven. We pull permits and get inspections signed on every eligible job, and we treat the inspector like he works for you, not for us. That’s one reason we’re comfortable putting our Bathroom Remodeling team’s reputation on the line in Claremont, block by block.
Our Bathroom Remodeling Services in Claremont
Full Bathroom Remodeling
Complete tear-outs and rebuilds, from waterproofing the studs to setting the final fixture. In Claremont’s older Craftsman bungalows near Indian Hill Boulevard, we frequently sister new framing alongside original balloon-framed walls, and we always check for galvanized supply lines that have narrowed to the diameter of a pencil after eighty years of hard water from the Pomona Valley aquifer.

Walk-In Showers & Shower Remodeling
We build walk-in showers with proper curbless entries where possible, which matters more than most people realize on the expansive clay soils common to the Pomona Valley floor. A slab that’s shifted a quarter inch can crack a poorly set shower pan in a year. We prep the substrate and waterproof the pan before we set a single tile, and we document it with photos.

Tub-to-Shower Conversion
For aging-in-place homeowners in Claremont’s 1950s-1970s ranch tracts, a tub-to-shower conversion is often the smartest bathroom investment they can make. We remove the tub, address the drain line if it’s original cast iron, and install a low-threshold shower with grab blocking in the walls. These jobs usually run $3,500 to $10,000 in Claremont, and we schedule them so you’re not living with a dead bathroom for more than a few days.

Vanities, Tile & Fixtures
From vanities built to fit the odd corners of a Spanish Colonial Revival bath off College Avenue to our Driveway & Pavers in Claremont and tile work that holds up through summers that routinely push past 105°F, we handle the details. Claremont’s extreme heat means cheap adhesives and thin grout fail faster here than they would at the beach. We set tile with polymer-modified thinset rated for high temperature swings, and we use Schluter waterproofing systems on wet walls as a standard, not an upgrade.

Trusted Brands We Service in Claremont
We carry materials you can look up. On the window and door side, we install Ply Gem and Simonton products, which matter in Claremont because the same Chapter 7A requirements that govern roofs also push for tighter fenestration on hillside remodels. We keep common parts accessible for our Claremont jobs so a broken hinge or a mismatched trim piece doesn’t stall your bathroom while you wait for a shipment. When we order a vanity, a shower valve, or a sheet of glass, we tell you the brand and the wait time before you spend a cent.
Common Bathroom Remodeling Problems We See in Claremont Homes
- Original cast-iron drain lines. In the 1910s-1940s homes around the Claremont Village, the original drain stacks are often pitted from eighty years of use. We inspect them during demo, and if a section needs replacement, you get a written change order before we touch it.
- Slab-on-grade foundation movement. The expansive clay under Claremont’s 1950s-1970s ranch tracts expands and contracts with the heat. That movement shows up as hairline cracks in slab floors, which we address before setting tile or building a shower pan.
- Water damage from failed caulk and old shower pans. Claremont’s extreme summer heat dries out caulk and accelerates the failure of old rubber shower pan liners. By the time a homeowner sees water staining on a ceiling below a bathroom, the pan has usually been leaking for months.
- Undersized bathrooms with no storage. Many of Claremont’s original bungalows have bathrooms that were added decades ago without much thought to storage or ventilation. We rework these spaces with built-in niches, better lighting, and fans that actually move enough air to keep the room dry.
Pricing for Bathroom Remodeling in Claremont, CA
A typical full bathroom remodel in Claremont falls between $9,000 and $28,000. Small bathroom remodels, where you keep the existing layout and refresh fixtures, tile, and the vanity, run $5,000 to $12,000. A walk-in shower installation runs $4,500 to $12,000, and a vanity install alone is $800 to $3,000. What shifts the final number most is the condition of the plumbing and framing behind the walls, and whether you’re in an older wood-frame home near the Village or a more predictable ranch on a slab. You’ll get a written, itemized estimate before we start, and if the scope changes for any reason, the price changes on paper first. Call (877) 610-1318 for exact numbers for your bathroom. Estimates are free.

FAQs - Bathroom Remodeling in Claremont
We can usually schedule a visit to your Claremont home within a few days, and we never charge a trip fee inside the county. Call (877) 610-1318 and a live person will set up a time, not a voicemail box.

Expect $9,000 to $28,000 for a full bathroom remodel in Claremont, which is slightly higher than what you’d pay in flatland cities like Pomona because Claremont’s older housing stock and hillside code requirements add labor hours. You’ll see the exact difference in your written estimate.
Only if the scope changes, and only after you sign a written change order. Hidden rot or a failed drain line isn’t a surprise on the final bill. We show you what we found, show you the number, and get your signature before we proceed.
Yes. We pull permits and get inspections signed on every eligible job. The inspector works for you, not for us, and we’re happy to have him check our work. If a contractor tells you permits are optional, call someone else.
