Fast, Reliable Bathroom Remodeling Across Bonita
A full bathroom remodel in Bonita typically runs $9,000 to $28,000, with small bathroom remodels landing between $5,000 and $12,000. Most of the work our crews take on here involves 1960s and 1970s ranch-style homes that need real structural attention before the tile goes up, not just a cosmetic refresh. Call (877) 610-1318 and we’ll walk the space with you, put everything in writing, and tell you exactly what the county will require before we touch a wall.
Tom Barrett founded Barrett & Sons Construction in 1998, and the crews serving Bonita are his sons and their teams. We know that Bonita is unincorporated San Diego County, which means every permit runs through the County’s Department of Planning & Development Services, not a city hall. We know that much of Bonita sits inside CalFire Very High Fire Hazard Severity Zones. And we know what both of those facts mean for your bathroom remodel: more permit steps, more code requirements, and more contractors who get it wrong. We don’t. That’s the difference.
You want a bathroom that looks great and works for the next 25 years. You also want the county inspector to sign off the first time and your insurance company to stay quiet when the next Santa Ana blows through. Both of those things happen when the job is scoped right from the start. Call (877) 610-1318 for a free estimate, and we’ll explain exactly what your house needs before you spend a dollar.
Why Barrett & Sons Construction Is Bonita’s Preferred Bathroom Remodeling Company
We’re not the cheapest quote you’ll get in Bonita. We’re the one that holds up. Homeowners in 91902 and 91908 who have already been burned by a phone quote that changed at the door tell us they came to us because our name is verifiable. Tom Barrett publishes his name, his address, and his license number. Look it up. Ask anyone on your street. We live twenty minutes away; if something’s wrong, we want to know about it.
Our reputation in Bonita is built on one thing the national outfits can’t match: continuity. The same crew that demos your shower is the crew that sets the vanity and grouts the tile. No subcontractor roulette. No project manager you’ve never met. When a County PDS inspector flags something, we’re standing there with the plans, not scrambling from two cities away.
Every estimate includes a written scope of work. Every allowance is on paper. Every price change comes as a written change order before a single nail moves. And every job carries our 90-Day Done Right Promise: if it’s not done right, Tom comes back and makes it right, one call.
Our Bathroom Remodeling Services in Bonita
We offer the full range of Bathroom Remodeling services, but these are the four Bonita homeowners ask about most. Each one carries different permit implications in unincorporated county territory, and we’ll walk you through that before the quote is final.
Full Bathroom Remodeling
A full gut remodel in Bonita means pulling a permit through the County of San Diego, not City Hall, and that means the plan review cycle can stretch if the paperwork isn’t complete. We prepare permit submittals with the Chapter 7A details already spec’d, so your review doesn’t stall. Typical full bathroom remodels in Bonita run $9,000 to $28,000, with the higher end reflecting structural repairs, custom tile, and genuine plumbing relocation rather than a swap-in-place job.

Walk-In Showers & Shower Remodeling
Walk-in showers are the single most requested upgrade we see in Bonita’s older ranch homes. The original tub-shower combos are tight, and homeowners in their 50s and 60s want a zero-threshold entry they can use for decades. A walk-in shower installation in Bonita runs $4,500 to $12,000. When the shower sits against an exterior wall, which it almost always does in these floorplans, we spec ember-resistant vents and fire-rated sheathing at the permit stage, not after the inspector asks about them.

Tub-to-Shower Conversion
Converting a tub to a shower in Bonita costs $3,500 to $10,000. It sounds straightforward, but in this community it often isn’t. The original 1970s plumbing stacks in these custom and semi-custom builds were sometimes run in ways that don’t meet current County PDS code. We’ll camera the lines, tell you what’s actually behind the wall, and give you a written change order if the scope changes once we open it up. No surprise invoices at the end.

Vanities, Tile & Fixtures
Bathroom vanity installation in Bonita runs $800 to $3,000, and we carry premium lines you can look up: KraftMaid, Cambria, and Kohler. Tile is where we see the biggest quality gap between quotes. Cheap installers rush the waterproofing membrane. We don’t. In Bonita’s climate, where winter rains saturate the air and summer heat bakes the house, a failed shower pan membrane is a mold problem waiting behind the tile. We waterproof to code and beyond because we know what those valley-floor humidity swings do to a badly built enclosure.

Trusted Brands We Service in Bonita
When we install windows or ventilation in a Bonita bathroom that touches an exterior wall, we use products engineered for wildland-urban interface zones. Brands like Simonton and PGT carry impact and fire-rated lines that meet Chapter 7A requirements without looking like a fortress. We don’t install mystery brands off a van. These are products you can research, spec sheets the county inspector recognizes, and warranties that actually pay out. If your bathroom remodel includes an exterior window or a new exhaust vent, we’ll show you the product data before we order it, and the compliance documentation goes in your project file for your insurance carrier.
Common Bathroom Remodeling Problems We See in Bonita Homes
- County PDS permit stalls: Contractors who work mostly in incorporated cities assume there’s a city hall to file through. There isn’t. The County of San Diego Planning & Development Services handles Bonita permits, and incomplete submittals sit in review for weeks while your bathroom demo sits half-finished. We file complete packages the first time.
- CalFire Chapter 7A red-tags: A cheap quote skips the ember-resistant vent and fire-rated exterior sheathing. Then the inspector shows up just before drywall and red-tags the job. Now the wall comes back open, the schedule slips, and the “savings” evaporate in re-work. We spec Chapter 7A requirements in the original scope.
- Expansive clay soil stress: Older Bonita homes on post-and-pier or shallow slab foundations move as the valley’s expansive clay swells in winter and shrinks in summer. Original bathroom floors crack, shower pans flex, and tile grout pops. We assess the substrate before we set anything.
- Floodplain oversight: Parcels in lower Bonita near the Sweetwater River may fall inside FEMA flood zones. A bathroom remodel under the base flood elevation without an elevation certificate can mean an insurance denial after the next winter storm. We check FEMA designations before we break ground on any lower-valley property.
Pricing for Bathroom Remodeling in Bonita, CA
Here’s what you should expect to pay in Bonita, based on what we’ve bid and built in this community over the years. These aren’t national averages; they’re calibrated to local labor, county permit fees, and the cost of Code Chapter 7A-compliant materials.
| Service | Price Range in Bonita |
|---|---|
| Bathroom Remodel | $9,000 - $28,000 |
| Small Bathroom Remodel | $5,000 - $12,000 |

What moves you up or down on that range? Structural condition of the subfloor and joists, whether you’re moving plumbing or keeping it in place, the grade of tile and fixture you pick, and whether your exterior wall needs fire-rated upgrades to pass County PDS inspection. That last one isn’t optional in much of Bonita. It’s code. A cheap quote that leaves it out isn’t a better deal, it’s an unfinished permit and a wall that has to come back open.
Every estimate from us is free, written, and specific to your house. We’ll tell you which line items are driven by Bonita’s county permit process and fire code, and why. Call (877) 610-1318 to schedule a walkthrough.

FAQs - Bathroom Remodeling in Bonita
Yes. Bonita is unincorporated San Diego County, and bathroom remodels that touch plumbing, electrical, structural framing, or exterior walls require permits through the County’s Department of Planning & Development Services. A water-only fixture swap may slide, but moving a drain line or cutting an exterior vent absolutely needs a permit. We pull them on every eligible job, and the inspector signs off before we close the wall. Skipping permits in Bonita can complicate a future home sale and void the workmanship protection that written code compliance provides. Call (877) 610-1318 if you’re not sure what your scope triggers.
Because much of Bonita sits inside CalFire-designated Very High Fire Hazard Severity Zones, and San Diego County enforces Chapter 7A wildland-urban interface construction standards on remodels that touch exterior walls or roofs. That means ember-resistant vents, fire-rated sheathing, and enclosed eaves are code, not upgrades. We include them in the original scope because the county inspector will require them, and the alternative is a red-tag just before drywall. It’s a line item a national outfit might leave out to win the bid, and it’s exactly the line item the inspector will notice when he walks in. Call (877) 610-1318 for a quote that actually matches what Bonita’s code demands.
Possibly, and we’ll verify it before we write the scope. Lower Bonita parcels near the Sweetwater River can fall inside FEMA flood zones, and if your structure sits below the base flood elevation, any remodel that affects the floor or foundation may require an elevation certificate and flood-resistant construction details. We recently remodeled a 1970s ranch bathroom near the floodplain, and the county permit review flagged the original post-and-pier foundation for expansive clay soil movement before sign-off. Our crew replaced the rotted subfloor around the tub and installed an ember-resistant vent through the exterior wall, then framed a Kohler walk-in shower that met both Chapter 7A and FEMA elevation requirements. Call (877) 610-1318 and we’ll check your address before you plan the project.
The way they should: in writing, before any new work happens. When we open a wall in a Bonita home and find rotted framing, a cracked vent pipe, or foundation movement the permit drawings didn’t show, we stop and give you a written change order with the exact scope and cost. You approve it or you don’t, but you never get a surprise invoice at the end. That’s why we say the allowance that isn’t on paper is a surprise waiting for a date. We handle county inspection corrections the same way: the inspector’s finding gets documented, we quote the fix, and you sign off before we proceed. Call (877) 610-1318 to discuss your project and get everything scoped in writing from the start.
Often, yes, though we can’t promise a specific premium change from our side of the table. What we can promise is documentation. A county-inspected remodel with verified Chapter 7A compliance gives your insurer evidence that the work was built to the same standard they underwrite against. If you’re in a CalFire Very High Fire Hazard Severity Zone, upgrades like ember-resistant vents and fire-rated exterior sheathing are factors some carriers weigh when you renew. Lower Bonita homes built below the base flood elevation are the exception: an unpermitted remodel without an elevation certificate can get a claim denied outright after a storm. We’ll give you the compliance paperwork your agent will want to see. Call (877) 610-1318 and ask us about the documentation trail on your job.
Barrett & Sons Construction serves all of Bonita, including both 91902 and 91908.
