Fast, Reliable Bathroom Remodeling Across Redlands
Bathroom remodeling in Redlands costs between $18,000 and $45,000 for a full gut and rebuild, with most homeowners in the 92373 and 92374 zip codes landing around $26,000 to $34,000 once hidden conditions are addressed. That range exists because older Redlands homes, especially the pre-war bungalows near downtown, routinely hide things behind the plaster that change the scope once walls come down. We’re Sapphire ADU Builders, led by Nelson Avery, and we’ve remodeled enough bathrooms in Redlands to know exactly what those hidden conditions look like and how to price them honestly. Call (855) 594-0655 for a free estimate, and we’ll walk your floor plan with you before any numbers get committed.
Why Sapphire ADU Builders Is Redlands’s Preferred Bathroom Remodeling Company
We’re not a general contractor who happens to do bathrooms. Our Bathroom Remodeling team specializes in full interior scope work, which means we own framing, plumbing, electrical, waterproofing, and tile from the first inspection to the final fixture. Redlands homeowners call us because we speak the language of their houses: Craftsman framing, galvanized supply lines, failed pans from the 1960s, and the permit triggers that come with each one.
Nelson Avery built this company around a simple idea: tell the homeowner what’s behind the wall before you quote it. In Redlands, that matters more than in most cities. A 1920s bungalow in the Smiley Park area has different bones than a 1970s ranch off San Bernardino Avenue, and we price accordingly. Our customers across Redlands regularly tell us the inspection-first approach is why they trusted us over lower bidders. We serve every neighborhood from the downtown historic core to the citrus-grove flatlands, and we’re reachable at (855) 594-0655.
Our Bathroom Remodeling Services in Redlands
Full Bathroom Gut and Rebuild
When a Redlands bathroom gets gutted, we’re not just swapping tile and fixtures. We’re dealing with whatever the original builder left behind: undersized joists, cracked cast iron, and sometimes no subfloor to speak of. We strip to the studs, assess what still works, and rebuild with pressure-treated plates, properly spaced framing, and modern waterproofing systems that will outlast the next owner.

Waterproofing and Shower Pan Installation
The single most common failure in Redlands bathrooms is water finding its way into places it was never supposed to go. Pre-war homes often have tile set directly on mortar with no pan liner or vapor barrier behind it. By the time we see it, the framing below is usually stained or soft. We install full waterproofing systems: cement board, liquid membrane or sheet membrane, pre-sloped pans, and proper drain assemblies that pass inspection the first time.

Permit-Driven Electrical and Plumbing Upgrades
Once a wall is open in Redlands, the building department requires work to be brought up to current code. That means GFCI protection, proper venting, and supply lines that aren’t held together by rust and hope. We pull permits on every project where walls come down, and we handle the inspection calendar so you’re not chasing the city. It’s not optional; it’s how the job gets signed off in this city.

Historic and Character-Home Bathroom Work
Remodeling a bathroom in the Redlands Historic District means working within a planning culture that cares about what changes. We’ve done enough of these to know how to preserve original tile details when you want them, and how to replace them with period-appropriate materials when you don’t. The important part is that the work still meets code, and we don’t cut corners to make a facade look old.

Trusted Brands We Service in Redlands
Our broader work with prefab ADU manufacturers like Cover, Dvele, and Boxabl means we’re fluent in modern building systems that translate directly to bathroom work. When we specify a waterproofing assembly or a ventilation solution for a Redlands remodel, it’s the same standard we’d use in a factory-built unit from a brand like Mighty Buildings. We also keep relationships with local Redlands suppliers, which helps on lead times for specialty fixtures and trim. You get the benefit of brand-agnostic advice and a single team responsible for the finished room.
Common Bathroom Remodeling Problems We See in Redlands Homes
- Cloth-wrapped wiring and ungrounded circuits. Homes built in the 1890s through the early 1920s around downtown Redlands often still have original two-wire electrical. Once a wall opens, the inspector will flag it, and a rewire becomes part of the job, not an option. We budget for it up front.
- Failed waterproofing behind old tile. The original owners of a 1920s Redlands bungalow didn’t think about vapor barriers. A cosmetic retile over a compromised substrate will leak into the framing again. We strip to studs and start the waterproofing from zero.
- Rotten or undersized framing around tubs and showers. Pre-war footprints in the 92373 core often have joists spaced wider than modern standards. Cement board and tile are heavier than what those joists were built to carry, so we sister framing before we set any backer board.
- Shallow or rusted tub drains with no slope. Cast iron from the 1950s and 1960s in east-side Redlands ranch homes tends to look fine from above but be nearly closed inside. When the drain can’t carry water at code slope, we re-route it while the floor is open.
Pricing for Bathroom Remodeling in Redlands, CA
A cosmetic refresh on a small Redlands bath starts around $12,000 to $18,000, but that’s surface-level work: new vanity, fixtures, paint, maybe a tub-to-shower conversion. A full gut on a 5×8 hall bath in a pre-war home typically lands between $22,000 and $32,000 once you account for electrical upgrades, waterproofing, and rough plumbing. Larger primary baths in the big ranch homes east of town run $35,000 to $55,000 or more, especially when you add heated flooring, custom tile, or structural work. The wild card in Redlands is always the hidden wall condition, which is why we write allowances into every contract for electrical, rough plumbing, and framing repair.

FAQs – Bathroom Remodeling in Redlands
Because Redlands pre-war homes routinely hide cloth-wrapped wiring, galvanized supply lines, and rotted framing behind the plaster, and none of that is visible during a walkthrough. A fixed-price quote that doesn’t include an allowance for these conditions is a guess. We do a structured inspection first and write allowances into the contract, so when we open a wall and find something unexpected, it’s already priced and approved. Call (855) 594-0655 for a real quote.
Yes, in most cases. When a building inspector sees original ungrounded wiring or a missing GFCI, code requires correction before the project can pass. In the 92373 downtown core especially, that often means a full or partial rewire of the bathroom circuit, not just swapping a receptacle. We plan for it from day one.
We strip to the studs and start over. No patching, no sealing over failed tile. A proper waterproofing assembly in a Redlands remodel means cement board, a membrane system, a pre-sloped pan, and a flood test before tile goes up. Anything less just postpones the leak.
Yes. The work has to respect the district’s character, but interior bathroom changes are generally approved as long as the structure meets current code. We’ve handled projects near the Smiley Park area where the exterior couldn’t change but the interior was completely rebuilt. We coordinate with the city on what’s allowed.
A rear garage conversion in the citrus-grove flatlands needs the same standard as any living space: proper waterproofing, code-compliant electrical, and ventilation. For ADU bathrooms specifically, we recommend compact three-quarter layouts with curbless shower pans and wall-hung fixtures to keep the footprint efficient. Our ADU experience means we know how to make a small bathroom feel functional, not cramped. Call (855) 594-0655 and we’ll share what’s worked on past conversions.
