Why Home Base ADU Builders Is Perris’s Preferred Bathroom Remodeling Company
Neil Bradshaw founded Home Base ADU Builders because he saw too many Riverside County homeowners get burned by contractors who quote low, then change-order the job to death once the walls are open. Perris is one of the more affordable entry points into Southern California real estate, and that means a lot of 30-to-40-year-old homes with original plumbing and tile work that’s past its service life. We’ve remodeled bathrooms in the 92570, 92571, and 92572 ZIP codes where the original shower pan had been leaking into the sill plate for years before anyone noticed. That’s local knowledge you can’t get from an out-of-town bid.
Our Bathroom Remodeling team works from Fountain Valley but schedules Perris jobs in full-week blocks so we’re not driving back and forth mid-project. When you call, you’ll speak with someone who knows the difference between a 1970s ranch on a half-acre off Ellis Avenue and a 1997 tract home near the Perris Auto Speedway, because the plumbing, slab condition, and permit path are different. Neil personally reviews every Perris estimate before it goes out. You won’t get a subcontractor roulette wheel. You’ll get our crew, our project manager, and a written scope at rough-in.
We’re not a generalist contractor dabbling in bathrooms. We focus exclusively on residential living space: ADUs, kitchens, and bathrooms. That focus matters in Perris, where a bathroom remodel often connects to a larger rear-yard ADU or garage conversion on the same lot. When the time comes, we can run both scopes under one contract, one schedule, and one point of accountability.
Our Bathroom Remodeling Services in Perris
Full Bathroom Gut Renovations
Most Perris homes we open up need full gut renos, not face-lifts. A gut renovation means we take the room to studs, replace the wet wall plumbing, re-frame rotted areas, and rebuild with proper waterproofing. For Perris tract homes from the 1980s and 1990s, this is almost always the right call once we confirm what’s behind the tile. You get a new subfloor, new drainage, new electrical, and a bathroom that meets current California code.

Walk-In Shower Conversions
Replacing a fiberglass tub-and-surround combo with a curbless or low-curb walk-in shower is one of the most requested upgrades in older Perris homes. The catch: many original installs used greenboard and mastic, not cement board and a waterproof membrane. If we’re pulling the tub, we’re inspecting the subfloor and framing underneath. In Perris’s hot, dry climate, poorly sealed showers fail fast: the summer heat bakes the mastic, the grout cracks, and water finds the framing. We build with a proper membrane system rated for the temperature swings these homes see.

Hall Bath and Guest Bath Updates
A hall bath remodel in a Perris 1980s tract home is a different animal than a master bath in a newer build. These rooms are small, often 5-by-8 or 5-by-9, and they sit over a concrete slab. Moving the toilet or shower drain means cutting the slab, which is doable but requires a permit and a structural inspection. We’ll tell you honestly if relocating the drain is worth the extra $2,500 to $4,000 or if we can improve the layout without moving wet walls.

Bathroom Remodels in Detached ADUs and Garage Conversions
Perris has seen a wave of ADU and garage conversions since California’s post-2020 ADU laws made detached units easier to permit. Many of those units include a compact bathroom that needs finishing or upgrading. Because we build ADUs in Perris as well as remodel the main house, we can handle a casita bathroom exactly the way we handle a primary bath: inspection first, written allowance for surprises, and a build that passes Perris inspection the first time. One contractor from foundation to finished bathroom, including the toilet, shower, vent, and water heater tie-in.

Trusted Brands We Service in Perris
We stock and install fixtures from Delta, Kohler, Moen, and American Standard for Perris customers, and we’ll pull parts the same week from our local supply lines so a missing cartridge or valve doesn’t stall your finish date. When you want a premium finish, we’ll order from the full catalogs without markup games, and we’ll tell you if a box-store vanity at $600 will hold up as well as a custom-framed one at $1,400. In a hot, dry house, the wrong vanity material will warp within two summers. We’ll steer you toward laminate, solid surface, or properly sealed wood for Perris conditions. Our team also works with the same prefab and custom building partners we use on ADU projects, so if your bathroom remodel connects to a larger Perris ADU build, the bathroom scope is already in-house. From Tuff Shed conversions to fully custom detached units, we’ve built across the spectrum, and the interior finish work is part of that single-contractor relationship.
Common Bathroom Remodeling Problems We See in Perris Homes
- Polybutylene supply lines: Homes built from roughly 1978 to 1995, which covers a large share of Perris’s housing stock, often used gray polybutylene pipe. It’s known to degrade and pinhole. We’ve opened walls off Nuevo Road and found active leaks that the homeowner never knew about. If we find it, the fix is a replumb of the wet wall in PEX, priced and approved before we proceed.
- Cracked cast-iron drains under the slab: Perris sits on expansive clay soil that moves with moisture changes. That movement cracks the original cast-iron closet bends and drain lines under bathroom floors. The crack often shows up as a persistent sewer smell or a slow leak that stains the slab. A PVC splice or full drain replacement is a common change order on older Perris homes.
- Greenboard waterproofing failures: Before the early 2000s, many builders used drywall or greenboard behind tile with mastic instead of cement board and a waterproof membrane. By now, most of those installations have failed. Rotted subfloor and sill plates around shower pans are the most common structural repair we make in Perris. The cosmetic refresh you planned becomes structural work the moment we pull the first tile.
- Code upgrades triggered by a permit: Perris building permits require GFCI protection, an exhaust fan vented to the exterior, and a pressure-balancing valve for any shower or tub. 1980s builds wired bathrooms with generic outlets and bare-bones fans. Once walls are open, the inspector will flag the wiring and vent. We write these upgrades into our initial estimate whenever we know a permit is being pulled, so the cost is on the table before we start, not a surprise after.

FAQs – Bathroom Remodeling in Perris
If your 1989 Perris home still has original polybutylene supply lines and you’re opening the wet wall, yes, we will strongly recommend replacing them with PEX during the remodel. Polybutylene is no longer code-compliant and is known for pinhole failures. We’ll confirm what’s there during our inspection and give you a written cost before we start. Call (866) 403-9834 to schedule a walk-through.
Not a full electrical upgrade, but it does trigger bathroom-specific upgrades: GFCI protection on all outlets, a dedicated 20-amp circuit for the bathroom, and an exhaust fan vented to the exterior. On a 1980s Perris tract home, the original wiring often doesn’t meet those requirements. Our initial estimate includes these upgrades whenever a permit is part of the job.
Because builders in the 1980s and 1990s often used greenboard or drywall behind tile with mastic, not cement board and a waterproof membrane. In Perris’s hot, dry climate, grout cracks in the summer heat, water seeps behind the tile, and the mastic fails. By the time a remodel starts, the subfloor and sill plate under the shower pan are often rotted. We include subfloor inspection and repair allowances in our Perris quotes up front.
Yes. We build and finish ADUs and garage conversions across Perris, including compact bathroom scopes inside those units. The plumbing, electrical, and ventilation requirements are the same as a house bathroom, and a permit applies if you’re adding or moving wet walls. We handle the full scope under one contract. Call (866) 403-9834 and ask for Neil Bradshaw’s team.
We start by removing the toe-kick or an access panel to look at the plumbing and subfloor before we quote structural work. We check the supply lines, the drain condition, the shower pan framing, and the electrical routing. Then we give you a written estimate with line items and allowances for what we find. If a surprise comes up during demo, we write a change order and wait for your written approval before we spend a dollar on it. No one gets a surprise invoice from us.
