Fast, Reliable Bathroom Remodeling Across Claremont
A bathroom remodel in Claremont typically costs between $18,000 and $45,000 for a full gut-and-replace, with smaller refreshes starting around $8,000 and larger primary-suite additions reaching $65,000 or more. We’re Home Base ADU Builders, and while our name says ADU, our Bathroom Remodeling team has been opening walls in Claremont’s older homes long enough to know exactly what’s behind them. That matters more than most homeowners realize. Call (866) 403-9834 for a free estimate, and we’ll walk your Claremont home with you before a single tile comes up.
Claremont isn’t like the rest of Southern California. The housing stock near the Colleges and the Village dates to the 1910s and 1920s, and that means every remodel starts with questions most contractors in newer developments never have to ask. What’s the framing actually doing behind that original tile? Is that wiring knob-and-tube? Did someone notch a stud for a drain line fifty years ago? We know these homes because we’ve worked in them, from the Craftsman bungalows off Indian Hill Boulevard to the Spanish Colonials tucked near Memorial Park. When you call us, you’re not explaining Claremont to someone who’s never driven Foothill Boulevard.
Our crew reaches every Claremont neighborhood, from the tree-lined streets near the Claremont Colleges to the ranch homes off Base Line Road, within a day or two for an estimate. We park in tight driveways, we respect heritage trees, and we know the city’s permit desk by first name.
Why Home Base ADU Builders Is Claremont’s Preferred Bathroom Remodeling Company
Claremont homeowners keep calling us back because we’ve learned to write contracts that anticipate what older construction hides. A lot of remodelers quote a low fixed number, disappear when a surprise shows up, and return with a change order that doubles the job. We don’t work that way. Neil Bradshaw founded this company on the idea that a written allowance for hidden conditions isn’t a loophole; it’s honesty on paper. We inspect before demolition, price the likely unknowns, and get your written approval on any discovery before we touch it. That’s why our Claremont reviews consistently mention the same thing: no surprises they weren’t told about first.
We’re also not a fly-by-night operation from another county. Our crews work the Pomona Valley regularly, and we’ve handled remodels within blocks of the Village, up in the foothill-adjacent streets like Indian Hill and Mills Avenue, and throughout the 91711 zip code. Claremont’s tree canopy and historic character make every site visit different, and we’ve learned to plan for protected oaks and citrus trees that sit exactly where a homeowner pictures a bump-out. We don’t fight the lot. We design around it.
When a Claremont homeowner calls with a backed-up drain or a cracked cast-iron flange at 7 a.m., we answer. You get a real person who knows the difference between a 1920s lath-and-plaster wall and a 1970s ranch drywall job. That local knowledge is what makes a one-hour estimate useful rather than vague. Call (866) 403-9834 and find out.
Our Bathroom Remodeling Services in Claremont
Full Bathroom Gut & Replace in Claremont
For homeowners in Claremont’s older bungalows, a full gut is often the smartest path. We strip to the studs, assess what’s behind the original tile, and rebuild the room as a system rather than a surface patch. That means new waterproofing, new venting, corrected framing, and fixtures that will outlast the next owner’s taste. Homes near the Claremont Colleges often have bathrooms that were last touched in the 1950s, and what looked like a simple refresh becomes a structural repair job the moment the wall opens. We budget for that from day one.
Shower & Tub Replacement
Replacing a shower or tub in Claremont usually runs $7,000 to $18,000 depending on whether we’re swapping a fiberglass insert or building a tile shower with a custom pan. In pre-war homes, the bigger cost driver is what we find under the old pan: failed lead-pan waterproofing is common, and the subfloor beneath it is often soft. We replace the pan, repair the framing, and rebuild the shower to current code. It’s not a one-day cosmetic job. It’s a proper installation that won’t leak into the room below.
Tile & Flooring Installation
Claremont homes lean warm and traditional, and we’ve laid more than our share of hex tile, subway tile, and Spanish-style floor tile in bathrooms near the Village. But before the tile goes down, the floor has to be right. Many 1920s and 1930s bathrooms have 1×6 diagonal subflooring that has sagged over ninety years, and laying tile over a bouncing floor means cracked grout within a season. We fix the structure first, then set the tile. Homeowners who’ve lived through a cheap flip know the difference.
Accessibility & Aging-in-Place Bathroom Updates
Claremont has a strong population of long-time homeowners who plan to stay in their homes, and we see more curbless showers, comfort-height toilets, and blocking for future grab bars than most contractors expect. These changes can be invisible when done early, and they cost far less than retrofitting later. For a 1950s ranch near the Claraboya area or a bungalow near the Village, we quietly integrate accessibility into every remodel so the bathroom serves the next thirty years, not just the next open house.

Trusted Brands We Service in Claremont
Claremont homeowners often ask whether they should buy fixtures from a big-box store or through us. The answer depends on what you want. We regularly install Delta, Kohler, Moen, and Toto fixtures in Claremont bathrooms, and we stock common repair parts for these brands in our local inventory, which means a leaking Kohler valve doesn’t wait a week for a shipped part. For prefab shower systems and wall surrounds, we work with manufacturers including Plant Prefab and Boxabl when a homeowner wants a modular approach, and we’ve handled Tuff Shed-to-bathroom conversions on Claremont lots where a detached unit made more sense than expanding the main house. We don’t push any single brand. We match the fixture to the home’s age, style, and your budget.
Common Bathroom Remodeling Problems We See in Claremont Homes
- Failed lead-pan waterproofing behind original tile. In pre-1950s Claremont bathrooms, the original waterproofing was a lead sheet folded into a shower pan. After 70 or 80 years, it corrodes and leaks, and the first sign is often a stain on the ceiling below. We replace the pan with a modern membrane and repair whatever framing the water weakened.
- Notched studs and cut joists from old plumbing work. Plumbers in the 1950s and 1960s didn’t think twice about notching a 2×4 stud or cutting a joist to squeeze in a waste line. We find these constantly in Claremont bungalows, and they need sistered repairs before any new tile goes up.
- Ungrounded knob-and-tube wiring hiding behind the medicine cabinet. A simple vanity swap turns into an electrical code correction when the wall opens and decades-old wiring appears. Claremont’s permit process requires bringing accessible wiring up to code before we close the wall, and we’ll tell you that before we start, not mid-project.
- Vent stacks buried in wall chases. Homes built before modern plumbing codes often have vent lines that dead-end in the attic or run horizontally too far. The inspector will flag it, and cutting it right means opening more wall than the tile area suggests. We plan for this contingency in our written allowances.

Here’s what we tell every Claremont homeowner before we write a contract. A cosmetic refresh, where we keep the existing layout and replace fixtures, tile, and vanity, typically runs $8,000 to $15,000 in Claremont.

Call (866) 403-9834 to schedule a free walk-through, and we’ll price your specific Claremont bathroom against what we’ve actually found in similar homes nearby.

FAQs – Bathroom Remodeling in Claremont
Yes, any remodel that moves plumbing, alters the drain, or changes the footprint of a bathroom requires a city permit in Claremont, and yes, a permit often triggers mandatory upgrades. The inspector can require you to bring accessible wiring to modern code, correct an undersized drain, or fix venting that was never compliant. We handle the permit application, coordinate inspections, and write the likely corrections into your contract before demo starts. If you want to avoid the permit conversation entirely, a cosmetic resurfacing with no plumbing changes may not require one, but we’ll tell you honestly either way. Call (866) 403-9834 to talk through your specific project.
We don’t start demolition until we’ve done a pre-demo inspection of the likely trouble spots, and we write a priced allowance into your contract for the most common findings: framing repairs, subfloor replacement, electrical corrections, and venting. If we open the wall and find something worse than expected, we stop, document the condition, price the repair in writing, and get your approval before we touch it. In Claremont’s older homes, dry rot behind original tile and notched studs are so common we’d be lying if we didn’t budget for them up front. You’ll never be told the job doubled after the fact. For an exact quote on your home, call (866) 403-9834.
The most common surprise is framing that was compromised decades ago. On a 1920s bungalow near the Colleges, our crew opened a bathroom wall to relocate a shower valve and found the original 2×4 studs had been notched for a 1950s waste line, leaving less than a third of the member intact. We wrote a framing repair allowance into the contract before demo, and after inspection the homeowner approved a priced, written change order for sistered studs and a new subfloor before we touched the waterproofing. That’s how it should work everywhere, and that’s how we work in Claremont. To find out what’s behind your tile, call (866) 403-9834.
Yes, we can source period-appropriate tile and fixtures for historic Claremont bathrooms, and we’ve matched replacement hex tile, subway tile, and chrome fixtures in Craftsman and Spanish Colonial homes near the Village. Matching original tile exactly in color and thickness sometimes means ordering from specialty suppliers with longer lead times, and we’ll tell you that before you commit. For fixtures, we can usually reuse restored originals or find reproductions that read correct to the period. If you’re unsure whether your bathroom is worth preserving, call (866) 403-9834 and we’ll give you an honest read.
Claremont’s building department is generally responsive, but plan review for a bathroom remodel with structural changes typically adds one to three weeks before we can start work, and inspections are scheduled during normal business hours. The timeline impact depends on what the permit scope uncovers. If the inspector requires electrical or plumbing corrections, that adds days of coordinated work, not months. We handle all scheduling and stand for every inspection, so you’re not waiting around for a city official. Most Claremont bathroom remodels with surprises run four to six weeks from start to final inspection. For a timeline specific to your home, call (866) 403-9834.
