Fast, Reliable Bathroom Remodeling Across San Dimas
A full bathroom remodel in San Dimas typically runs between $9,000 and $28,000, with smaller projects like a tub-to-shower conversion landing closer to $3,500-$10,000. We know those aren’t small numbers, which is why every dollar gets accounted for in writing before we pick up a hammer. Barrett & Sons Construction has been remodeling homes in the San Gabriel foothills long enough to know that a San Dimas bathroom isn’t the same job as one twenty miles south. If you’re ready to talk real numbers and real timelines, call (877) 610-1318. Tom Barrett answers his own phone, and he’ll give you a straight answer.
Why Barrett & Sons Construction Is San Dimas’s Preferred Bathroom Remodeling Company
Tom Barrett founded this company in 1998 and never sold it to a franchise group. His sons run the crews here in San Dimas, and Tom is on-site most days, not sitting in a regional office. That’s the difference between a name on a truck and a face you’ll run into at the hardware store on Bonita Avenue. Our reputation in San Dimas is built on written change orders, permits pulled on every eligible job, and the 90-Day Done Right Promise printed right on the contract, not hidden in a drawer.
We’ve worked on ranch-style tract homes from the 1960s near San Dimas Avenue and custom-graded hillside properties up in the northern foothills. That matters because a bathroom in a flatland rancher behaves differently than one in a cut-and-fill hillside home where slab settling and moisture intrusion follow different rules. Our Bathroom Remodeling team knows which questions to ask before we open a single wall. When customers call from the 91773 ZIP code, they get a live person, 24/7. Not a voicemail box, not an out-of-state call center. Free estimates, no trip charge inside the county, and if you’ve got a written estimate from another contractor, we’ll give you a free second opinion on it. Look up our license number yourself. Tom publishes it, along with his name and address. Ask anyone on your street, or look up the license number yourself.
Our Bathroom Remodeling Services in San Dimas
Full Bathroom Remodeling
A full bathroom remodel in San Dimas means tearing down to the studs where needed, moving plumbing if the layout fights you, and rebuilding with materials that make sense for a foothill climate. We handle permits, inspections, and every trade in-house. In older San Dimas homes, we regularly find supply lines and drain stacks that haven’t been touched since the Eisenhower administration. That’s where the written change order matters. You’ll know before we know what’s behind the tile, because the allowance isn’t on paper before we start, it’s a surprise waiting for a date.

Walk-In Showers & Shower Remodeling
Walk-in showers are the most requested feature we build in San Dimas, especially for homeowners in their 50s and 60s who plan to stay in their homes. We build curbless entries, bench seating, grab-bar blocking behind the tile, and shower systems you can actually service without tearing out a wall. A walk-in shower installation in San Dimas typically runs $4,500-$12,000 depending on size, tile selection, and whether we’re moving the drain. We install glass enclosures, from framed to true frameless, and we measure on-site before ordering anything.

Tub-to-Shower Conversion
If you’ve got a 1980s tub that nobody uses, a tub-to-shower conversion in San Dimas runs $3,500-$10,000 and can usually be completed in under two weeks. We demo the tub, reframe as needed, waterproof properly, and set a shower pan or tile floor that drains the way it should. In hillside homes where the slab has settled over the years, we level the pan before tiling. That’s the difference between a shower that holds water and one that pools it against the wall. San Dimas homes up in the foothill parcels deal with more slab movement than the flatland tract homes down by the 210, and we plan for it.

Vanities, Tile & Fixtures
We set vanities, tile, and fixtures that don’t need to be babied. That means solid cabinet boxes, tile laid on a properly floated surface, and valves you can get parts for at a supply house, not a mystery brand off a van. A bathroom vanity installation in San Dimas runs $800-$3,000, and we’ll tie into existing plumbing or move it if the new layout calls for it. We carry premium brands across the scope so you can look up every material before you sign the contract.

Trusted Brands We Service in San Dimas
We don’t stock a warehouse full of off-brand fixtures and hope you won’t ask. For San Dimas bathrooms, we build with brands like KraftMaid and Cambria, materials you can research before we order. When it comes to tile and shower systems, we use manufacturers with real distribution in the San Gabriel Valley, so if a part fails three years from now, you aren’t waiting on a shipment from overseas. We also work with Belgard and Techo-Bloc on hardscape projects around San Dimas homes, so if your bathroom remodel turns into a patio refresh, we can handle that too.
Common Bathroom Remodeling Problems We See in San Dimas Homes
- Cast-iron and galvanized drain lines that have lived past their warranty. Most San Dimas homes built before 1980 have original drain stacks, and they fail from the inside out. We scope the line before we build, so you don’t finish a $20,000 bathroom and lose it to a drain backup six months later.
- Slab settling in hillside properties. Homes in the northern foothill parcels often sit on cut-and-fill grading, and the slab moves. That movement shows up in cracked shower pans, leaking flange seals, and grout that won’t stay put. We address the subfloor before tile goes down.
- Ventilation that wasn’t designed for a modern bathroom. Older San Dimas ranchers have single small exhaust fans that can’t move the moisture from a walk-in shower. We size and route new venting, and we vent to the exterior, not into the attic. That’s a code item and a mold item both.
- Dual-jurisdiction permit confusion. Parcels on the same street in northern San Dimas can fall under either the City of San Dimas or unincorporated LA County, and each has its own plan-check process. We identify jurisdiction before submittal so your project doesn’t stall mid-permit. The permit inspector works for you, not for me. That’s why I like him.

FAQs - Bathroom Remodeling in San Dimas
We can usually start a San Dimas bathroom remodel within two to four weeks after the contract is signed and permits are in hand. The permit timeline depends on whether your parcel falls under the City of San Dimas or unincorporated LA County, which can change plan-check duration. Call (877) 610-1318 for a straight answer on current scheduling.
Yes. We work from the flatland ranch homes off San Dimas Avenue up through the northern foothill parcels that sit in the Very High Fire Hazard Severity Zone. We don’t charge a trip fee inside the county, and we don’t turn down a job because the driveway is steep. The hillside homes take more planning for slab movement and drainage, but we’ve been doing that since 1998.
Slightly, and for a real reason. Many San Dimas parcels, especially north of the 210, sit in a fire severity zone that adds Chapter 7A compliance requirements when the project triggers those codes. That can add material costs for ignition-resistant assemblies. On a typical bathroom remodel in the flatland areas, pricing tracks closely with Pomona and La Verne. Call (877) 610-1318 for an exact quote, and we’ll break out every line item in writing.
A full bathroom remodel in San Dimas typically takes three to six weeks from demo to final inspection, depending on scope, tile work, and whether the project involves any slab-leveling or plumbing relocation. Small bathtub replacements can finish in under a week. We’ll give you a written schedule before work starts and update you every day the crew is on-site.
Yes. The 90-Day Done Right Promise is printed on every contract, including San Dimas bathroom remodels. If something isn’t right, one call brings Tom Barrett back to make it right. No argument, no gatekeeper. That’s the promise. Call (877) 610-1318 for your free estimate, and if you already have a written bid from another contractor, bring it in and we’ll give you a free second opinion.
