AfterFast, Reliable Bathroom Remodeling Across Bonita
Bathroom remodeling in Bonita, CA typically costs $9,000-$28,000 for a full remodel, with walk-in shower installations running $4,500-$12,000 and tub-to-shower conversions at $3,500-$10,000. Most projects take 3-6 weeks from permit approval to final county inspection, though canyon-rim properties in the High Fire Hazard Severity Zone add a Chapter 7A materials coordination step that many contractors miss.
We’re Rowan Construction Group, and our crews work Bonita regularly - from the ranch-style homes off Bonita Road to the hillside properties near the Sweetwater River valley. We also offer our Kitchen Remodeling in Bonita for homeowners looking to update more than just their bathrooms. Dispatch and scheduling run through our San Diego office, but the trucks that show up at your door are the same ones that have been pulling county permits for Bonita’s unincorporated lots since 2007. Call (619) 536-0571 to schedule your free estimate, or bring us a competitor’s written quote for a line-by-line second opinion at no charge.
Why Rowan Construction Group Chula Vista Is Bonita’s Preferred Bathroom Remodeling Company
We’ve delivered more than 4,000 projects since 2007, and a growing share of them are in Bonita’s 1960s-1980s ranch neighborhoods. These homes sit on large lots - often half an acre or more - with original slab foundations that show settlement cracking in the clay-heavy hillside soils. That substrate condition is not a surprise to us; it’s a line item in our written scope, with a photo record of what we find before demolition and what we install after.
Our Bathroom Remodeling team knows the county DPS permit path cold. Bonita has no city building department. Contractors who build across the line in Chula Vista and assume the same process apply here routinely stall mid-project. We don’t.
Reviews from Bonita customers mention the same things: the written price arrived before anyone picked up a tool, the crew was uniformed and background-checked, and the documented photo record showed every stage. Our 365-Day Done Right Promise is printed on every page, backed by a terms page - not an asterisk.
A live person answers our phones 24/7. Not a voicemail tree. A person who can confirm your appointment, note your gate code for the horse property, and flag the county Agriculture review if your barn sits within setback distance of the bathroom addition.
Our Bathroom Remodeling Services in Bonita
Full Bathroom Remodeling
A full bathroom remodel in Bonita starts with understanding what’s under the floor. The 1970s ranch homes that dominate this market often have original slab foundations with settlement cracks that telegraph through to tile. We open with a moisture-meter and substrate inspection, document what we find with photos you receive, and write the repair into the scope before demolition starts. On canyon-rim lots, we also specify Chapter 7A ember-resistant vent assemblies and exterior penetration materials at rough-in - a county requirement that adds cost but protects your insurance position later.
Walk-In Showers & Shower Remodeling
Walk-in shower installation is our most requested Bonita service, especially among homeowners replacing original tubs in the area’s aging ranch stock. We source Kohler and Toto fixtures through our fifty-plus vetted brand network, which keeps the written quote honest rather than inflated. The membrane system - the waterproof layer beneath your tile - gets a flood test before walls close. In Bonita’s High Fire Hazard Severity Zone properties, we coordinate the county fire-overlay submittal with the plumbing inspection so neither step blocks the other.
Tub-to-Shower Conversion
Tub-to-shower conversion in Bonita runs $3,500-$10,000 depending on whether the slab needs leveling and whether the drain line requires relocation. The original tubs in these 1960s-1980s homes are often cast iron on a bed of mortar that adds significant demo weight. We haul, we don’t subcontract that out. And we check the county grading ordinance before breaking ground on hillside properties where the bathroom sits on a cut or fill slope.
Vanities, Tile & Fixtures
Vanity installation in Bonita homes sometimes reveals wall framing that isn’t plumb - common in the post-and-beam construction of the area’s older ranches. We shim and document, never hide it behind caulk. For tile, we specify crack-isolation membrane on any slab with visible settlement history. Cambria and Caesarstone countertops are quoted from our direct supplier relationships; KraftMaid and Wellborn cabinets are measured to your space, not pulled from a big-box inventory.
Small Bathroom Remodels
Bonita’s guest baths and pool baths - often added in the 1970s and 1980s - run 5′ x 8′ or smaller. A small bathroom remodel at $5,000-$12,000 can still include a walk-in shower, new vanity, and tile surround if the substrate is sound. We flag the condition of the original vent fan and ductwork, which in Bonita’s climate can harbor moisture and mold behind the ceiling.

AfterTrusted Brands We Service in Bonita
We maintain supplier relationships across fifty-plus vetted brands, which means the fixtures and materials in your Bonita bathroom remodel are sourced at trade pricing we pass through - not marked up to cover a showroom lease. For showers and wet areas, we regularly specify Kohler valves and Toto fixtures, with tile setting materials from manufacturers whose membranes carry ICC-ESR evaluation reports the county inspector recognizes. On roofing-adjacent bathroom vents and penetrations, we use GAF and Owens Corning assemblies rated for the wind and fire exposure this area requires. We stock common replacement parts locally, so a failed valve cartridge or cracked soap dish doesn’t turn into a two-week order delay.
Common Bathroom Remodeling Problems We See in Bonita Homes
- Slab settlement cracking under original tile. The clay-heavy soils on Bonita’s hillsides shift seasonally. We find cracked mud beds and failed membranes in roughly half the 1970s-era bathrooms we open. The fix is a crack-isolation system and, in some cases, self-leveling underlayment - both written into the scope before we start, not discovered as a change order mid-job.
- Original galvanized supply lines behind tub surrounds. These pipes reach end-of-life around 50 years, which means most Bonita ranch homes are due. We replace with PEX-A or copper and pressure-test before closing walls. The photo record shows every joint.
- Non-compliant vent terminations in High Fire Hazard Severity Zone properties. Bathroom exhaust vents that terminate through the roof or soffit with standard plastic hoods fail Chapter 7A. We specify ember-resistant metal terminations with integral mesh screens, documented in the compliance package for your insurer.
- County permit delays from contractors unfamiliar with unincorporated DPS. Bonita is not Chula Vista. The permit application, fire-overlay submittal, and inspection scheduling all route through the county’s Department of Planning & Development Services. Contractors who submit city-style plans get rejected. We submit county-style the first time.

FAQs - Bathroom Remodeling in Bonita
The San Diego County Department of Planning & Development Services issues all bathroom remodel permits in Bonita, because Bonita is unincorporated county land - not a city. There is no Bonita city building department. The county requires a separate fire-overlay submittal for properties in the High Fire Hazard Severity Zone, and the grading ordinance applies to hillside construction. Call (619) 536-0571 and we’ll confirm which county path your property requires before we write the quote.
Yes. Chapter 7A of the California Building Code mandates ember-resistant construction materials at exterior wall penetrations, including bathroom exhaust vent terminations and any plumbing or electrical penetrations through exterior walls. Standard plastic vent hoods fail inspection. We specify metal terminations with integral mesh screens and document the assembly for your insurance file. Call (619) 536-0571 for a quote that includes compliant materials from the start.
A written scope of work with line-item allowances; a draw schedule tied to inspection milestones; explicit slab repair and leveling allowances; Chapter 7A material specifications if your property is in the fire zone; and a signed change-order protocol. Cheap quotes often omit these, then discover “unforeseen conditions” mid-demo. Under The Haven Standard, we document what we find before demolition and write the repair into the original scope whenever possible. Call (619) 536-0571 for a written quote you can compare line by line.
Because unpermitted work in unincorporated San Diego County triggers title issues on resale, insurance claim denials, and county code enforcement with fines that start at double the permit fee. More critically, a permitted project with documented Chapter 7A compliance supports your wildfire-mitigation insurance credit. The permit is not red tape; it is a record that protects your investment. Call (619) 536-0571 and we’ll handle the county submittal as part of our scope.
Yes. If your bathroom project touches or sits within setback distance of an existing barn, arena, or hay storage structure, the county Department of Agriculture reviews alongside county Planning. This dual-agency coordination can add weeks to the timeline. We identify this risk during our initial site visit and build the buffer into the schedule. Contractors who treat Bonita horse properties as standard residential jobs get surprised mid-process. Call (619) 536-0571 to schedule a site visit that flags these issues before the quote is written.
