Why Barrett & Sons Construction Is Bonita’s Preferred Bathroom Remodeling Company
Tom Barrett started Barrett & Sons in 1998, and he’s still the guy who shows up at your door to walk the job. That’s the difference Bonita homeowners tell us they remember. You’re not getting a rotating cast of subcontractors from two counties away. You’re getting Tom, his sons, and the same background-checked crew members who carry the Barrett & Sons name on their shirts.
We’ve remodeled bathrooms all over Bonita, including the larger ranch lots along Sweetwater Road, older homes off Central Avenue, and homes tucked into the hills near the 805. Homeowners in Bonita keep our number because we answer the phone with a live person, 24 hours a day. Not a voicemail box. Not a call center in another state. A person who knows where Bonita is and can talk through your project without reading a script.
Every quote we give is a written scope of work with written allowances. If the price changes, you get a written change order before any work happens. That’s the way we operate. It’s why you’ll find our name in conversations at the Bonita post office and why we’re not afraid to tell you to look up our license number before you sign anything.
Our Bathroom Remodeling Services in Bonita
Most Bonita bathrooms were built when shag carpet was still a design choice. We help you bring them forward without losing the character of a 1960s or 1970s custom home. Here’s what we do best in Bonita.
Full Bathroom Remodeling
A full bathroom remodel in Bonita typically means gutting an original 1960s bathroom down to the studs and rebuilding it to handle modern plumbing, ventilation, and waterproofing. In Bonita, we also check for old slab and post-and-pier foundation quirks before we set anything. Older ranch homes here were built on expansive valley clay, and after 50 years, a floor that looks flat can be hiding a subtle slope. We address that before tile goes down, not after.

Walk-In Showers & Shower Remodeling
Walk-in showers are the most requested upgrade in Bonita right now, especially for homeowners planning to stay in their homes into their 70s and beyond. We install curbless entries, built-in benches, and grab-bar blocking behind the walls even if you don’t need the bars yet. The blocking is cheap when the wall is open; retrofitting it later is expensive. This is the kind of thing we build into every Bonita shower remodel by default.

Tub-to-Shower Conversion
If your original cast-iron tub is chipped, stained, or you’re done stepping over the side, a tub-to-shower conversion in Bonita runs $3,500-$10,000 depending on layout and finishes. We do this frequently in Bonita’s older homes because the original tubs are often 300 pounds of porcelain-coated iron set on wood framing that’s decompressing after six decades. Getting rid of the tub often reveals subfloor work that needs addressing, and we scope that in writing before we start, not as an afterthought.

Vanities, Tile & Fixtures
From a custom vanity to full tile surrounds, we handle the pieces as well as the whole job. We carry premium brands you can look up, and we install them correctly. In Bonita’s ranch homes, vanity placement often competes with original window openings and wall sconce wiring from the Truman administration. We solve those layout problems instead of pretending they don’t exist. Tile, fixture, and vanity work starts around $800-$3,000 for a vanity replacement and scales from there.

Trusted Brands We Service in Bonita
We stock and install name-brand materials for Bonita customers, including Simonton, Ply Gem, and PGT products where the job calls for impact-rated or high-efficiency glass. When a bathroom window needs replacing as part of your remodel, we bring the right product the first time, not a mystery brand off the back of a van. Our Windows & Doors in Bonita work dovetails with bathroom remodels, especially when an old aluminum window over the tub needs to go. We also carry the same standard across our Bathroom Remodeling division, so materials and approaches stay consistent from room to room.
Common Bathroom Remodeling Problems We See in Bonita Homes
- Original cast-iron plumbing at the end of its life. Bonita homes built in the 1960s and 1970s often still have original drain lines that have rusted from the inside out. We see it on nearly every full tear-out. It’s not a scare tactic; it’s the reality of 60-year-old pipe.
- Slab movement from expansive clay soil. Bonita’s valley floor sits on clay that swells with winter rain and shrinks in summer dry heat. That movement can crack slab foundations and leave bathroom floors slightly out of level, which shows up as cracked tile or gaps at the baseboards in homes that were remodeled without addressing it first.
- Water intrusion from Santa Ana wind-driven rain. When Santa Anas funnel through the Sweetwater River valley, horizontal rain can work its way around old window frames and worn flashing. In bathrooms with exterior walls or windows, we see water damage that homeowners mistake for a plumbing leak. We inspect both.
- County permit confusion and fire-zone requirements. Bonita is unincorporated, so permits run through San Diego County’s Planning & Development Services, not a city hall. Portions of Bonita also sit in CalFire Very High Fire Hazard Severity Zones, which means any significant remodel may bring Chapter 7A building code requirements into play, including ember-resistant vents and specific exterior material standards. Outside contractors who don’t know this often get red-tagged mid-project.
Pricing for Bathroom Remodeling in Bonita, CA
A full bathroom remodel in Bonita runs $9,000-$28,000. Small bathroom remodels fall between $5,000 and $12,000. A walk-in shower installation lands between $4,500 and $12,000, and tub-to-shower conversions run $3,500-$10,000. Shower replacements start around $3,000 and top out near $8,500. Vanities alone can be $800-$3,000, depending on size and material.
What moves the number in Bonita is usually the age of the house. Older ranch homes with original plumbing and compromised subfloors cost more to do right than a 1990s home with clean framing. Fire-zone compliance can also add a line item if your remodel triggers Chapter 7A requirements. What doesn’t change the number is mid-project surprises. We put scope in writing, allowances in writing, and change orders in writing before anything changes. Call (877) 610-1318 for a free, written estimate specific to your Bonita home. Senior and veteran customers get 10% off, permanently, no catch.

FAQs - Bathroom Remodeling in Bonita
Most full bathroom remodels in Bonita take 2 to 4 weeks from demo to final walkthrough, assuming no hidden structural work. Smaller jobs like vanity replacement or tub-to-shower conversion are often done in under a week. The timeline in Bonita can stretch if we uncover original slab movement or fire-zone code items that require county review, which is why we scope carefully upfront. Call (877) 610-1318 and we’ll give you a realistic timeline for your specific house.
Yes. Every eligible bathroom remodel in Bonita includes permits pulled and inspections signed. Because Bonita is unincorporated, the process runs through San Diego County’s Department of Planning & Development Services, not a city hall. We know that workflow and we build it into your schedule from day one. The permit inspector works for you, not for us, which is exactly why we like him. Call (877) 610-1318 with questions about what your job will require.
No. There is no trip charge inside the county, and that includes Bonita, 91902, 91908, and all surrounding areas we serve, where we also provide Bonita Driveway & Pavers services. Your estimate is free, and the price we give you is the price on the contract, with written change orders for anything that shifts later. Call (877) 610-1318 to set up a site visit at no cost to you.
It’s mostly the age and construction style of the houses. Bonita’s custom ranch homes from the 1950s through the 1980s often need subfloor repair, plumbing replacement, and foundation assessment before new tile goes down. Some neighborhoods also fall inside fire hazard severity zones, which can trigger Chapter 7A code requirements like ember-resistant venting on exterior walls. Those are real costs in Bonita that don’t exist in a 2005 tract home two exits north. That’s why our written allowances matter. You’ll know every line item before work starts. Call (877) 610-1318 for an exact number.
Every completed bathroom remodel in Bonita is backed by our written 90-Day Done Right Promise. If something isn’t right, one call brings Tom back to make it right. It’s written on your contract, not hidden in fine print. We also honor manufacturer warranties on every product we install. Call (877) 610-1318 to talk through your project and see how the warranty applies to your specific scope.
Yes. If your bathroom window is rotted, we replace it as part of the job. If water is getting in from above, we also handle Roofing in Bonita. We’re a full construction company, so you don’t have to coordinate three contractors and hope they show up in the right order. Tom and his sons are on-site most days, and every trade we touch carries the same written-scope standard. Call (877) 610-1318 and tell us what’s going on at your house.
