Nate Calloway leads our bathroom remodeling work in Perris. He’s spent enough time in Riverside County tract homes to know what’s behind these walls before the first hammer swings. That matters when the difference between a clean remodel and a blown schedule is a concrete slab nobody planned to cut.
Why Costa Mesa ADU Builders Is Perris’s Preferred Bathroom Remodeling Company
Perris homeowners call us because we understand what a stucco-on-slab tract home actually requires. Most of the city’s housing stock was built between the 1980s and early 2000s: concrete slabs, attached garages, deep backyards. That construction type changes how you move drain lines, where you run venting, and how you waterproof a shower pan. We’ve remodeled bathrooms in detached casitas off D Street, in primary homes near Perris High, and in ADUs backing onto open valley land west of the 215. The scope changes every time, but the approach doesn’t: figure out the slab first, plan the plumbing second, and build the finishes to last through Perris summers.
We’re not a bathroom franchise running a playbook written for coastal condos. We do full-scope interior work, which means the same crew that remodels a Bathroom Remodeling project in your primary house can also handle the bath inside a new detached ADU on the same lot. One contract, one point of accountability, no trade handoffs. Perris customers routinely tell us that’s the difference between their project finishing on schedule and stalling for weeks waiting on a sub.
Our reputation in Perris is built on showing up when we say we will and keeping the site clean on tight lots where staging space barely exists. We know which streets near downtown have narrow driveways. We know the wind patterns that kick up dust on the west side of town. We plan around those realities instead of pretending they don’t exist.
Our Bathroom Remodeling Services in Perris
As our Perris remodeling team, we handle the full range of bathroom work, from a simple tub-to-shower conversion in a 1990s tract home to a complete slab-cut remodel in a detached backyard ADU. Here’s what we do most often in this city.
Full Bathroom Gut and Replace
A gut remodel in a Perris tract home means pulling everything to the studs and slab, relocating plumbing if the layout changes, and rebuilding with materials suited to a hot, dusty inland valley. We typically install fiber-cement wet walls behind tile where moisture and temperature swing are constant. In detached ADUs, that often includes cutting the slab to move a drain line. We plan for that from the first quote, not as a mid-project surprise.
ADU Bathroom Remodel and Slab-Cut Plumbing
This is the work that separates experienced Perris contractors from everyone else. Remodeling a bathroom in a detached casita usually means relocating a shower drain through a concrete slab, which requires a saw cut, trenching, and re-pour with a sloped pan. We’ve done this on deep lots off D Street and on west-side parcels backing onto open dairy land. The slab itself is often the biggest single line item in an ADU bath remodel, and we’ll show you exactly where that money goes.
Tub-to-Shower Conversions
Perris homeowners aging in place or setting up an ADU for a parent frequently convert a tub to a curbless or low-curb shower. These conversions reduce fall risk and open up floor space in smaller bathrooms. On a slab, we build the shower pan with a properly sloped mud bed and waterproofing membrane rather than relying on a prefab fiberglass pan that rarely sits level on a 30-year-old concrete floor.
Ventilation and Moisture Control Upgrades
Perris bathrooms fail early when ventilation can’t keep up. Wind-driven dust off adjacent fields clogs standard exhaust fans within months, leading to trapped moisture and mildew. We spec higher-CFM fans with backdraft dampers for west Perris and any lot backing onto open land, and we size the vent run to the actual distance to the exterior wall. It’s a detail most crews skip, and it’s the reason so many Perris ADU bathrooms smell musty two years in.

Trusted Brands We Service in Perris
When a prefab ADU from Mighty Buildings, Boxabl, or Plant Prefab needs a bathroom remodel during or after the main build, we handle it. Prefab units arrive with rough plumbing in place, but the interior work still has to be done on-site, and Perris conditions don’t change just because the shell was built in a factory. We’re familiar with the wall assemblies and plumbing layouts these manufacturers use, which means we can quote bathroom work inside a prefab ADU accurately instead of guessing at what’s behind the paneling. We also work with Dvele units where higher-end finishes come standard and the remodel is more about layout and fixture replacement than full gut work.
Common Bathroom Remodeling Problems We See in Perris Homes
- Slab-on-grade surprises: Most Perris bathrooms sit on concrete, not wood subfloor. Moving a drain means cutting the slab, which adds $2,500 to $6,000 to the job depending on trench length and re-pour depth. Contractors who quote on wood-framed assumptions underbid, then hit you with change orders once the saw comes out. We price the slab work up front.
- Wind-driven dust wrecking ventilation: West Perris and lots backing onto open valley land get constant wind and fine dust. Standard 50-CFM exhaust fans clog within a season, and that trapped moisture eats grout and sheetrock. We spec fans with backdraft dampers and higher static pressure ratings for these lots.
- Tight staging on small-lot homes near D Street: Older Perris homes close to the historic downtown have narrow driveways and minimal side access. Material drops and demolition debris removal need planning ahead of time. We coordinate dumpster placement and protect neighboring property lines so you don’t inherit a complaint or a stop-work order.
- Permissive ADU ordinance, complicated plumbing runs: The city encourages detached units, which is great. But trenching a new drain line from a backyard casita to the main sewer lateral can mean cutting across 60 feet of concrete backyard pathway. We bring that reality into the estimate before you commit, not after demo starts.
Pricing for Bathroom Remodeling in Perris, CA
Here’s what we see in the Perris market right now:
- Full bathroom gut and replace: $18,000 to $42,000. A 1990s tract-home master bath with mid-range tile, new vanity, new shower, and updated ventilation runs $22,000 to $30,000 typically.
- Detached ADU bathroom remodel with slab-cut plumbing: $15,000 to $28,000. Moving a shower or toilet drain through a slab adds $2,500 to $6,000 on top of the standard scope.
- Tub-to-shower conversion: $9,000 to $16,000. Curbless shower pans on a slab run higher than low-curb options because of the re-pour work.

What moves the number most in Perris is slab work. A bathroom that keeps its original footprint can be remodeled without cutting concrete, and that’s where the savings come from. Moving fixtures is where the cost grows. We give you a written line-item quote before work starts, and the price we quote is the price you pay unless you change the scope.

FAQs – Bathroom Remodeling in Perris
Yes. Perris requires permits for any bathroom remodel that moves plumbing, cuts into the slab, changes the electrical layout, or alters the building envelope. A simple fixture-for-fixture swap with no plumbing movement may qualify as a repair, but if you’re relocating a drain in a detached ADU, you need a building permit and likely a plumbing and electrical permit. We pull all permits on your behalf and schedule the inspections. Call (833) 589-8273 and we’ll tell you exactly what your project triggers.
It adds $2,500 to $6,000 to a bathroom remodel that moves plumbing. In Perris tract homes and detached ADUs, drain lines are buried in concrete, so relocating a shower or toilet means saw-cutting the slab, trenching, and re-pouring with a sloped pan. A wood-framed floor would allow a plumber to reroute drains in a few hours. On a Perris slab, that same change takes two to four days and requires concrete work. We include slab cutting as a line item in our quote, never as a surprise change order. Call (833) 589-8273 for an exact number on your project.
Perris enforces a standard noise ordinance that restricts heavy work, including saw-cutting and demolition, to daytime hours, typically 7 a.m. to 7 p.m. on weekdays with tighter limits on weekends. If your lot is close to your neighbor’s house, especially in the small-lot area near downtown along D Street, we coordinate the loudest phases during mid-morning hours when complaint risk is lowest. On lots backing onto active dairy or agricultural land, we also schedule around neighboring work patterns so our demolition doesn’t collide with someone else’s early-morning schedule. We handle this coordination as part of the job.
We upgrade the ventilation to handle it. Standard exhaust fans in a Perris ADU bathroom on a lot backing onto open valley land or dairy acreage clog fast, and the dust destroys fan motors within two years. We install higher-CFM fans rated for continuous or long-cycle operation, add backdraft dampers to the exterior vents, and route duct runs with as few turns as possible. During the remodel itself, we seal off the work area with zip walls and run an air scrubber when we’re cutting inside the ADU, so the dust from our own work doesn’t settle into the house. Call (833) 589-8273 to talk through what your specific lot needs.
Yes. We remodel bathrooms in prefab ADUs from Mighty Buildings, Boxabl, Plant Prefab, and Dvele. The process differs from a traditional slab-cut remodel because the wall assemblies and plumbing chases are built to factory tolerances. The plumbing rough-in is usually accessible through a dedicated chase, which means less slab cutting. We understand those layouts, so our quotes for prefab unit bathroom work are based on what’s actually inside the wall, not generic assumptions. Call (833) 589-8273 for a free estimate on your prefab ADU bathroom remodel.
