AfterFast, Reliable Bathroom Remodeling Across Ontario
A full bathroom remodel in Ontario, CA typically runs $9,000 to $28,000, with smaller bathrooms landing between $5,000 and $12,000. We’re Barrett & Sons Construction, and we’ve been remodeling bathrooms across Ontario since Tom Barrett founded the company in 1998. When you call (877) 610-1318, Tom or one of his sons answers. Not a call center. Not a voicemail box. You’ll talk to someone who knows Ontario from the 91762 ZIP down to Ontario Ranch, and who will show up when he says he will.
Our Bathroom Remodeling crews serve the entire city, from older craftsman bungalows near Euclid Avenue to brand-new tract homes in the southern growth zone. We pull permits, we schedule inspections, and we put every price change in writing before a single nail moves.
Why Barrett & Sons Construction Is Ontario’s Preferred Bathroom Remodeling Company
We’re the owner-operated alternative to the national outfits that quote one price on the phone and show up with another. Tom Barrett lives twenty minutes from Ontario. His sons run the crews. When you hire us, the name on the truck is the name on the contract, and the people standing in your bathroom are the same people you’ll see at the hardware store on Saturday. Ask anyone around Ontario. Or look up Tom’s name, address, and license number yourself. They’re published and verifiable, because Tom wants you to check before you sign anything.
We don’t dispatch strangers. Our crew members are background-checked, uniformed, and they carry the Barrett & Sons name on every visit. We’ve been at this for over 29 years, and our 90-Day Done Right Promise is written on every contract. If it’s not done right, one call brings Tom back to make it right. That’s not a marketing line.

Our Bathroom Remodeling Services in Ontario
Full Bathroom Remodeling
We gut and rebuild bathrooms throughout Ontario, from the 1920s bungalows near Chaffey High School to the newer builds off Archibald Avenue. A typical full remodel in Ontario runs $9,000 to $28,000. What actually happens once the walls come down in an older Ontario home is what separates a competent contractor from a disaster. We open up your bathroom, inspect what’s behind the tile and under the floor, and put any required upgrades in writing before we proceed. No surprise invoices at the end.
Walk-In Showers & Shower Remodeling
Walk-in shower installation in Ontario runs $4,500 to $12,000, and it’s one of the most common projects we do for homeowners planning to age in place. We frame the shower for zero-threshold entry where the subfloor allows, waterproof the pan correctly, and use brands like Schluter for the waterproofing system. Because if the pan fails, you’re not fixing a caulk line. You’re tearing out tile and subfloor. We’d rather do it right the first time and stand behind it.
Tub-to-Shower Conversion
Converting a bathtub to a walk-in shower in Ontario costs $3,500 to $10,000. Older Ontario homes, particularly in the 91762 and 91764 ZIPs, often have cast-iron tubs sitting on original subfloor with galvanized supply lines. When we pull the tub, we frequently find pipes that are rusting from the inside. That’s exactly the kind of thing a written allowance in your contract covers, so the conversation about replacing those supply lines happens before the work begins, not after.
Vanities, Tile & Fixtures
Bathroom vanity installation in Ontario is $800 to $3,000. We install vanities, tile, and fixtures from brands you can look up: Grohe faucets, Sterling tubs and sinks, Schluter waterproofing. We don’t stock mystery brands off a van. Every material that goes into your Ontario bathroom has a name behind it, and you’ll see those names on your written scope before we order anything.

Trusted Brands We Service in Ontario
We install and stand behind materials from Schluter, Sterling, and Grohe across Ontario. These aren’t brands we picked because they were cheap. We picked them because they hold up under the hard water and heat cycles that Inland Empire bathrooms deal with, and because we can get parts quickly when something needs attention. For Ontario homeowners who want a shower system that won’t look dated in five years, we also bring GAF’s experience to bear on any shower-wall and pan detailing that touches framing, because a leak in a bathroom can become a roofing problem faster than most people realize when the damage works its way into the structure above.
Common Bathroom Remodeling Problems We See in Ontario Homes
- Cloth-wrapped wiring in pre-1960 homes. We opened up a 1938 craftsman bungalow in Ontario’s 91762 ZIP to find original cloth-wrapped wiring running through the bathroom walls. Our crew rewired the circuit, replaced the cast-iron drain stack with ABS, and reframed the load-bearing wall around the new walk-in shower. The homeowner approved the change order in writing before we touched the rough-in, and the final inspection sign-off took one visit.
- Failed shower pans from original construction. In Ontario’s older homes, many shower pans were built without modern waterproofing membranes. By the time you see a stain on the ceiling below, the damage has usually been growing for years. We pull the pan, inspect the subfloor, and write up exactly what we find before we rebuild.
- Santa Ana wind debris during open-wall work. During fall Santa Ana events, the Cajon Pass funnels serious wind through Ontario. If a bathroom is opened up without weather protection planned, debris blows into the drywall and the punch list gets delayed. We plan for wind before we open a wall, not after the dust starts flying.
- Differential settlement in Ontario Ranch tract homes. Ontario Ranch’s rapid buildout on former vineyard and dairy land means many pads were cut and filled aggressively. Local crews see differential settlement within a few years of original construction. When we install a new shower base or tile floor in southern Ontario’s 91761 area, we check for slab movement that could crack grout lines a year after the job’s done.

What moves the number most on an Ontario bathroom remodel is what’s hiding behind the walls. In a pre-1960 home, that’s galvanized supply lines, cloth wiring, and framing that doesn’t meet current California Building Code. A permit inspection walls-open triggers those upgrades. In a newer Ontario Ranch home, the issues are usually slab movement and production-grade fixtures that were never meant to last. Either way, our contract includes written allowances for what we expect to find, and every change order is priced and approved in writing before work proceeds. Call (877) 610-1318 for a free estimate. We’ll walk your Ontario bathroom, open the walls where needed, and hand you numbers on paper.

FAQs - Bathroom Remodeling in Ontario
In Ontario, bathroom remodels in pre-1960 homes nearly always trigger electrical and plumbing upgrades to meet current California Building Code. A permit inspection walls-open reveals cloth-covered wiring, ungrounded circuits, and galvanized supply lines that don’t pass today’s standards. The inspector requires these upgrades before the walls close up, which is why a lowball bid without allowances for old pipes or wiring means a surprise change order mid-project. Our contracts include written allowances for exactly these upgrades. Call (877) 610-1318 and we’ll walk your bathroom and tell you what to expect.
We pull the permit and we schedule every inspection. The permit inspector works for you, not for us, and that’s why Tom likes him there. He’s an independent set of eyes verifying the framing, waterproofing, and electrical are right before the walls close. For an older Ontario home, that inspection is the thing that stops a previous contractor’s unapproved framing changes from getting hidden behind new tile and red-tagged later. We don’t skip permits. They’re pulled on every eligible job, and the inspection sign-off is part of the job, not an option.
Look for written allowances for old galvanized pipes, cloth wiring, and failed waterproofing. Look for a stated scope that names your materials by brand, not by phrase. Look for a change order clause that requires written approval before any price moves. And look for a contractor who will publish his name, address, and license number so you can verify him before you sign. Barrett & Sons puts the 90-Day Done Right Promise on every contract, and every price change arrives in writing before a single nail moves. Call (877) 610-1318 to schedule your free estimate.
Yes. Ontario Ranch homes are newer, but they sit on former agricultural flatland with expansive clay soils and compacted fill. Differential settlement shows up within a few years of original construction. When we install shower pans or tile floors in the 91761 area, we check for slab movement before we set tile, because a shifted slab will crack grout lines a year later no matter how well the tile was laid. The older core’s risks are aging wiring and failed plumbing. The newer core’s risk is the ground underneath.
When Santa Ana winds blow through the Cajon Pass in fall, they hit Ontario hard. If a bathroom is opened up for a remodel without weather protection, debris blows into the drywall and delays the punch list. We plan for wind before we open a wall. That means sealing off the work area, covering openings, and scheduling material deliveries so nothing sits unprotected. It’s a small thing that keeps a two-day tile job from becoming a two-week headache. Call (877) 610-1318 for a free estimate, and ask us what your wind plan will be.
