Why Westminster ADU Builders Is Rubidoux’s Preferred Bathroom Remodeling Company
Westminster ADU Builders specializes in accessory dwelling units, but our in-house bathroom remodeling team has spent years modernizing the exact housing stock Rubidoux is built on. Mid-century tract homes and ranch-style layouts from the 1950s through the 1970s dominate this unincorporated community, and we know what that means structurally: cast iron drain lines, cloth-wrapped branch wiring, undersized vent stacks, and tile set directly on drywall with no waterproofing behind it.
Nate Calloway, who leads our remodeling division, has walked hundreds of these homes across Riverside County. He’ll tell you the same thing on day one that he tells every Rubidoux homeowner: we quote what we can see, write allowances for what we can’t, and never close a wall until the county inspector has signed off on the rough-in. That counts for a lot when you’re spending five figures on a room you use every day.
We’re a short drive up Mission Boulevard from any point in Rubidoux, and our local reputation in the Inland Empire was built on permit-heavy projects done without drama. Few contractors in the area do both Bathroom Remodeling and ADU construction under the same license, which means we’re current on Riverside County’s residential code in a way a bathroom-only shop rarely is.
Our Bathroom Remodeling Services in Rubidoux
Every project starts the same way: an inspection of the existing conditions, an honest conversation about scope, and a written plan that accounts for what a county inspector will require once the permit is pulled. Here’s what we handle most often in Rubidoux.
Full Bathroom Remodel with Permit Coordination
We pull the permit, schedule the inspections, and manage the full build from demolition through final sign-off. In unincorporated Riverside County, that means working with the County building department’s checklist, not the city of Riverside’s, and we handle every step of that process on your behalf. A standard hall bath gut in Rubidoux typically runs 10 to 16 working days once demo starts, depending on what the inspection reveals.
Waterproofing and Tile Replacement
The single most common failure we see in Rubidoux bathrooms is tile failing because the original waterproofing was never there. Many of these homes were built when 4-inch ceramic over drywall was standard practice, and forty or fifty years later the substrate is mush behind the grout. We strip to the studs, replace damaged framing, and rebuild with a full Schluter membrane or cement board and liquid membrane system that meets current county code.
Electrical and Plumbing Upgrades for Older Homes
Opening a Rubidoux bathroom wall often reveals cloth-wrapped wiring or, occasionally, aluminum branch circuits that have no place behind a modern GFCI. We bring everything up to code: dedicated 20-amp circuits for outlets, proper ventilation fans on timers or humidity sensors, and new supply lines and drain rough-ins where the original galvanized or cast iron has failed. The county inspector will require these upgrades as part of a permitted remodel, so we plan for them from the first walkthrough, not as an afterthought.
Shower and Tub Surround Replacement
Whether you want a full Schluter-built tile shower or a solid-surface surround with a lower maintenance profile, we’ll spec it for the inland heat. Rubidoux summers push humidity against poorly ventilated bathroom walls, and the right surface plus the right exhaust fan makes the difference between a surround that lasts twenty years and one that peels in three.

Common Bathroom Remodeling Problems We See in Rubidoux Homes
After working on bathrooms throughout Rubidoux’s mid-century housing stock, certain failures show up repeatedly. Here’s what we expect before we open the walls, and what we’re prepared to find once we do.
- Cloth or aluminum branch wiring. Homes built in the 1950s and 60s along Rubidoux Boulevard and the surrounding tracts were often wired with cloth-sheathed cable or aluminum branch circuits. The county will not sign off on a bathroom permit until these are brought to current code, which means a partial rewire is common.
- Rotted framing behind original tile. Without a vapor barrier or waterproof membrane, decades of shower steam have been soaking into the wall cavity. We regularly find softened 2x4s around tub surrounds in these ranch-style homes, and those studs need sistering or replacement before any new tile goes up.
- Undersized or nonexistent vent fans. Many original Rubidoux bathrooms relied on a single operable window, which is not current code and not enough in the inland heat. We add proper ventilation with a roof or wall exhaust, sized to the square footage, when we do any permitted remodel.
- Cast iron drain lines at the end of their service life. The original plumbing in these homes has been in the ground for over five decades. If we’re already opening the floor to relocate a drain or move a toilet, we’ll inspect the cast iron and replace any section that’s showing its age, so you don’t pay for a second tear-out two years later.
Pricing for Bathroom Remodeling in Rubidoux, CA
In the Rubidoux market, a cosmetic refresh of a small hall bath (new vanity, toilet, fixture swap, paint) typically runs $7,000 to $12,000. A full gut-and-replace of a typical 5-by-8 hall bath with new tub, tile surround, waterproofing, subfloor repair, electrical upgrades, and mid-range finishes usually lands between $14,000 and $22,000. A larger primary bath with a walk-in shower, custom tile, new framing, and significant plumbing movement runs $22,000 to $32,000 or more depending on the extras.
What moves the number more than anything else in Rubidoux is what’s behind the walls. A home with recent electrical updates and sound framing is straightforward. A 1962 original with cloth wiring and rotted studs needs more work, and our quotes include written allowances for those discoveries so you’re never hit with an unapproved cost mid-project. Every estimate is free, and it’s a line-item breakdown you can take to another contractor if you want to compare.

FAQs – Bathroom Remodeling in Rubidoux
Yes, if you’re moving plumbing, replacing valves or drain lines, altering wiring, or changing the footprint, you need a permit from the Riverside County building department, not the city of Riverside, because Rubidoux is unincorporated. We handle the entire permit process for you. If you’re only swapping the vanity and painting, no permit is required. Call (833) 620-3521 and we’ll tell you in one conversation whether your project needs to go through the county.
Most commonly, cloth-wrapped wiring, tile set directly on drywall with no waterproofing, and studs that have been absorbing shower moisture for fifty years. We’ve also found original cast iron drains and undersized framing around tubs. None of this is a catastrophe, but it does mean the real cost of a remodel isn’t fully visible until the walls are open, which is why we write allowances into every quote.
We photograph the issue, write a change order with a fixed price, and get your approval in writing before we proceed. You always know what it costs and why it’s required. Nothing gets buried and nothing gets sprung on you at the final invoice. That process is standard on every Rubidoux project we do, and it’s the main reason homeowners tell us the remodel felt manageable instead of chaotic.
Not necessarily. The county requires the circuits serving the bathroom to be brought to current code, but the rest of the house can remain as-is. If we find cloth wiring in the bathroom walls, we’ll replace that portion and install GFCI protection, but we don’t force a whole-house rewire unless the existing panel or service can’t support the load. Call (833) 620-3521 for an exact scope assessment, and we’ll tell you what the inspector will actually require before you commit to anything.
Rubidoux summers regularly push over 100 degrees, which means a bathroom that lacks proper exhaust and insulation becomes a mold and mildew incubator. We spec ventilation fans sized to the room’s cubic footage, use waterproofing systems that handle rapid temperature swings, and consider thermal bridging on any exterior wall. If your bathroom has a west-facing wall, we’ll talk about insulation upgrades while the wall is open, because it’s the cheapest time to do it.
