Why Westminster ADU Builders Is Highland’s Preferred Bathroom Remodeling Company
We’re an Abodu service in Highland and an ADU specialist first, which matters more than you’d think for bathroom work. The bathrooms inside a detached ADU run on the same systems as the main house, and when we remodel a bath in a Highland home, we’re already thinking about how the drain, vent, and electrical panel interact with everything else on the lot. That cross-project awareness is what keeps our remodels from turning into domino failures.
Nate Calloway leads our remodeling and ADU work across Highland, including the 92346 zip code. We’ve remodeled bathrooms in East Highlands Ranch, along Base Line, and in the older pockets off Greenspot Road where homes date to the 1950s and 1960s. Highland homeowners consistently tell us the same thing: the estimate was the most detailed they received, and the work matched it. That’s not an accident. We write allowances into the contract because we know what’s behind these walls.
We’re familiar with San Bernardino County’s permit process for Highland specifically, including the septic review step that trips up out-of-town contractors. And because we also build Bathroom Remodeling projects inside new ADUs, we’re equally comfortable with ground-up plumbing and retrofit work in a 1963 hall bath.
Our Bathroom Remodeling Services in Highland
Full Bathroom Remodel
A full remodel in Highland means taking the room to studs and rebuilding it. In the 1950s and 1960s homes that dominate this city, that almost always means replacing galvanized supply lines, adding a properly sized vent, and bringing the electrical up to current code. We handle the permit, the inspections, and the surprises that come with opening a 60-year-old wall. You get a written line-item quote, not a guess.
Shower and Tub Conversion
Converting a tub to a walk-in shower is one of the most practical upgrades for Highland homeowners who plan to stay in the home. But on raised foundations, swapping a 300-pound cast-iron tub for a tile shower changes the load on the framing. We sister joists and add blocking where needed, and if the drain moves, we flag it early because on properties with septic, a moved drain can trigger a county review. We’d rather tell you on day one than in week six.
Waterproofing and Tile
Highland’s hard water and dry heat punish poorly sealed showers. Failed pan liners are the single most common hidden problem we find in East Highland homes built before 1980. We use a full waterproof membrane system behind the tile, not just cement board and hope. That means a surface-applied or sheet membrane that ties the pan, walls, and curb into one continuous seal. It costs more than the shortcuts, and it’s the difference between a shower that lasts 20 years and one that rots the subfloor in six.
Bathroom Exhaust and Ventilation
Many original Highland bathrooms vent into the attic or into a dead-end soffit, which means moisture and mold never leave the house. When your remodel goes through permit, the county requires a compliant exhaust path to the exterior. We scope this during the estimate so the roof penetration and duct run are in the number before you sign. Not after the drywall is open.

Common Bathroom Remodeling Problems We See in Highland Homes
- Corroded cast-iron drains and galvanized supply lines. The slab homes and raised foundations built in Highland between 1955 and 1975 often have original plumbing that’s scaled shut or rusting from the inside. If a quote doesn’t include a camera inspection or a replacement allowance, the project stalls the moment the flooring comes up.
- Failed shower pan liners. We recently opened up a 1960s hall bath in the East Highlands area and found the cast-iron drain had scaled shut and the subfloor was rotted from a failed pan liner. Because the walls were open, the permit required bringing the circuit up to code, so we added a dedicated 20-amp GFCI line and upgraded the undersized framing before any tile went back. We priced the change order in writing and had it approved before the plumber touched the drain.
- Bathroom exhaust venting into the attic. Dead-end duct runs were standard practice in mid-century Highland construction. A permit-triggered remodel requires the vent to terminate outside, and the new roof penetration plus duct run can be a four-figure line item if it wasn’t scoped up front.
- Undersized floor framing under tubs. Hillside lots off Greenspot and along the base of the San Bernardino foothills often have raised foundations with joists that were never meant to carry a tile shower. Swapping a cast-iron tub for a walk-in shower changes the load, and framing allowances are the difference between a straight remodel and a surprise structural bill.
Pricing for Bathroom Remodeling in Highland, CA
A full bathroom remodel in Highland typically falls between $22,000 and $48,000. The spread isn’t about finish level as much as what’s behind the walls. A tub-to-shower conversion runs $14,000 to $26,000. Waterproofing and tile alone, when done correctly with a full membrane system, is $4,500 to $9,500 depending on shower size and tile choice. Exhaust re-routes through the roof add $800 to $2,200 when the original vent doesn’t terminate outside. Drain and supply line replacement on mid-century homes runs $2,500 to $6,500 if the plumbing has reached end of life. We write allowances into every contract based on what we see during the estimate walkthrough, and any surprise gets priced and approved in writing before we touch it.

FAQs – Bathroom Remodeling in Highland
Yes, any Highland bathroom remodel that alters plumbing, electrical, or structural elements requires a permit through San Bernardino County. Because many mid-century Highland homes still have original wiring and under-amperage circuits, a permit often triggers a requirement to bring the bathroom circuit up to current code, including GFCI protection and sometimes a 20-amp dedicated line. We handle this by scoping the likely upgrades during the estimate so they’re in the number before the permit is pulled. Call (833) 620-3521 and we’ll tell you exactly what your bathroom will likely trigger.
Because original cast-iron drains, galvanized supply lines, and failed waterproofing are common in Highland’s 1950s to 1970s housing stock, and a lowball quote simply omits them. We write inspection-based allowances into our contract for exactly these items, so the number you see is the number you approve. When we find something the estimate didn’t anticipate, we price it in writing and get your signature before any work begins. You’ll never get a surprise invoice from us.
If your Highland property is on septic and your remodel adds a fixture or alters the drain layout, the county typically requires a septic review as part of the permit process. This is one of the biggest differences between remodeling in Highland versus sewer-connected neighbors like Redlands or San Bernardino. We’ll identify whether your project triggers this review during the estimate and include any inspection or system upgrade costs in the written quote. Call (833) 620-3521 to find out where your property stands.
We use a full waterproof membrane system that ties the pan, walls, and curb into one continuous seal, not just cement board behind tile. Highland’s hard water and dry heat make failed pan liners one of the most common problems we see in homes from the 1960s and 1970s. A continuous membrane prevents the subfloor rot that a failed liner causes, and it’s the standard we won’t cut corners on. The cost is included in every shower remodel estimate we write for Highland homes.
We scope the exhaust path during the estimate, and if the original fan vents into the attic or a dead-end soffit, we include the roof penetration and duct run in the number before you sign. A permit-triggered remodel in Highland requires the exhaust to terminate outside, and retrofitting this on a mid-century home is a common, predictable cost. We’d rather tell you on day one than let it become a change order after the drywall is open.
