Fast, Reliable Bathroom Remodeling Across Banning
A bathroom remodel in Banning rarely stays a simple swap of tile and vanity once our crew opens the walls. Most homes in the 92220 zip code were built between the 1950s and 1980s, and they carry the wiring, plumbing, and waterproofing decisions of that era into every remodel. We scope every job inspection-first, write allowances into the contract, and price any surprise in writing before we touch it. That’s how a Bathroom Remodeling project in Banning finishes on budget instead of spiraling. Call (866) 808-7312 to schedule a walkthrough of your Banning home.
Why Cottage ADU Builders Is Banning’s Preferred Bathroom Remodeling Company
We work across the San Gorgonio Pass, and Banning’s housing stock is its own animal. Homes off Sunset Avenue, around the 22nd Street corridor, and up toward the foothills were framed and wired before modern code existed, and the local inspectors know exactly what they’re going to flag once a permit gets pulled. We know it too, because we’ve been through it on dozens of Banning jobs. That familiarity means our quotes account for the common issues before demo starts, not after.
Homeowners in Banning call us because we don’t flinch when a 1960s bathroom turns out to have galvanized supply lines or a shower pan that’s been leaking into the subfloor for a decade. Neil Stratton, our owner, has built the company around a simple rule: document everything, price changes in writing, and get your signature before we proceed. That’s the standard on every Banning job. Our local reputation is built on jobs that finished close to the original number because we planned for what these homes actually contain. Call (866) 808-7312 and we’ll walk your Banning bathroom with that same discipline.
Our Bathroom Remodeling Services in Banning
Full Bathroom Remodel with Inspection-First Scope
We start every full bathroom remodel in Banning by opening the walls with a clear scope agreement in hand. Before we quote, we look at the panel, the supply lines, the vent stack, and the subfloor. Then we write allowances for the issues these 1950s through 1980s homes typically hide. A hall bath on a Banning ranch house isn’t the same job as a master bath in a newer Calimesa build, and our pricing reflects that difference honestly.

Waterproofing and Shower-Pan Rebuild
The single most common failure we find in Banning bathrooms is a rotted subfloor under an old shower pan. Decades of hot summers and dry conditions don’t dry out a leaking pan; they just hide the damage until the tiles start moving. We rebuild pans on a proper sloped membrane, replace any compromised framing, and run the waterproofing up the walls to code. That work gets documented and inspected before we close anything up.

Electrical and Vent Upgrades Uncovered During Demo
Banning’s heat makes a properly sized exhaust fan essential, but many older 92220 homes have 60 to 100 amp panels with no spare breakers. When walls open and a GFCI circuit and ventilation are required by permit, the panel upgrade becomes part of the job. We price that as a written change order with photos and a clear scope before any electrical work begins. No one in Banning should get a bathroom remodel that can’t pass inspection on its own wiring.

Permit Coordination for 92220 Homes
We pull permits on every Banning bathroom remodel that requires one. That means the draftstopping, vent sizing, and electrical requirements that come with a Riverside County inspection are ours to manage, not yours to chase. We schedule the inspections, walk the job with the inspector when needed, and deliver a signed-off final on your bathroom.

Trusted Brands We Service in Banning
We’re known in Banning for our Bathroom Remodeling work on older homes, and the materials we specify hold up to the Pass. We use James Hardie fiber-cement on applicable exterior surfaces because wind and sun in this corridor chew through lesser siding. Inside, we install plumbing fixtures and ventilation systems from manufacturers we trust to perform in Banning’s extreme heat. We keep standard parts stocked locally so a remodel on a 92220 home doesn’t stall waiting on a specialty valve or trim kit. If you’ve been researching finish brands, we’re happy to spec them and tell you honestly what will and won’t hold up at 2,300 feet in the wind corridor.
Common Bathroom Remodeling Problems We See in Banning Homes
- Galvanized and aluminum branch wiring. Homes built in Banning’s boom decades often have wire that won’t safely carry a modern GFCI circuit and exhaust fan. The fix is either a panel upgrade or selective re-wiring, and it’s a code requirement once walls open, not an upsell.
- Failed shower-pan and tub-surround waterproofing. We regularly find subfloors that have been quietly rotting for years under old pans in homes near Central Avenue and up around Wilson Street. The damage hides until demo starts, but it’s repairable once the framing is exposed.
- Permit-triggered ventilation requirements. Banning’s 100°F+ summer days mean the exhaust fan has to work. Older homes often lack a proper vent run or the circuit to power it, so the permit triggers an upgrade that changes the job’s electrical scope.
- Septic-system drain constraints. Many Banning properties are on septic, and changing a bathroom’s drain or vent layout can pull the existing system into the permit review. We assess that before we quote, not after the rough-in is done.
Pricing for Bathroom Remodeling in Banning, CA

FAQs – Bathroom Remodeling in Banning
Because 1950s through 1980s homes in Banning hide wiring, plumbing, and waterproofing that a permit compels us to fix once walls are exposed. Galvanized supply lines, rotted subfloors, and overloaded panels aren’t optional discoveries. We handle this with inspection-first scoping and written allowances, so the “blow up” becomes a documented change order you approve before we proceed. Call (866) 808-7312 and we’ll show you exactly how that works on your home.
Often, yes, if your panel is 60 to 100 amps and has no spare breaker. Banning’s code requires GFCI protection and a working exhaust fan, and that fan has to run in 100°F heat. If the panel can’t support that, the inspector will flag it. We identify this in the walkthrough, so you know before the permit is pulled whether a panel upgrade is in your scope.
Yes, if you’re moving a drain or changing the vent layout. The county may pull the septic system into the permit review. We assess the existing drain lines during the walkthrough and flag any septic implications before we finalize a quote. That’s part of the local knowledge we bring to every 92220 job.
We rebuild shower pans and surrounds with a sloped, code-compliant membrane, and we replace any framing that’s been damaged by years of slow leaks. Banning’s dry heat doesn’t stop a failed pan from rotting the subfloor; it just keeps the damage invisible until demo. Our waterproofing gets inspected before it’s covered, so you’re not relying on a promise.
The permit forces code compliance on everything we expose. Ventilation, GFCI circuits, drain sizing, and waterproofing all get checked by the city. If your home predates current code, that means upgrades. We manage the permit, the inspections, and any change orders that arise, and we price each one in writing before the work starts. Call (866) 808-7312 for an exact quote, and we’ll tell you what your Banning bathroom will likely require.
