Bathroom remodeling in Highland, CA typically runs $18,000 – $42,000 for a full gut renovation of a standard 5×8 or 6×9 bathroom, with ADU bathrooms landing between $14,000 and $28,000 depending on finish level and whether we’re working inside a new unit or a converted garage.

If you’re planning a bathroom remodel anywhere in the 92346 zip code, call us at (866) 538-0916 for a free estimate and a written line-item quote. We know the permit process here, we know the older housing stock, and we know what it takes to get a bathroom signed off in Highland without surprise change orders.
What separates a Highland bathroom remodel from one in a flat valley city is simple: this is alluvial fan terrain at the base of the San Bernardino Mountains. Drainage slopes, Santa Ana wind exposure, and older unpermitted work all collide here. We plan for that from the first site visit.
Why Harvest ADU Builders Is Highland’s Preferred Bathroom Remodeling Company
Harvest ADU Builders approaches Bathroom Remodeling from an ADU-first perspective, which matters more in Highland than most homeowners realize. Many remodels here happen inside detached ADUs, garage conversions, or additions built decades ago when Highland was unincorporated San Bernardino County land. That history surfaces in plan review. Our team, led by Alan Pritchard, has walked enough Highland properties to know what the county will flag before we open a single wall.
We’re not a generalist remodeler who occasionally touches ADUs. We build detached units, convert garages, and finish interiors including bathrooms and kitchens under one scope. That means when a bathroom remodel inside a Highland ADU triggers a records review on the main house, we already know how to document it, legalize it, or write the disclosure so the permit doesn’t stall. Homeowners on the east side near Baseline Road, Weaver Street, and Victoria Avenue call us because we’ve already navigated their exact situation on neighboring lots.
Alan Pritchard has structured Harvest so every bathroom quote includes the paperwork burden that Highland specifically imposes. A cheap quote that skips the records review or the wind-load inspection will cost you more when the permit gets held up. Our fixed pricing means the scope we quote is the scope we build, including drainage corrections for alluvial-fan slopes and James Hardie backer board where moisture control is non-negotiable.
Our Bathroom Remodeling Services in Highland
Full Bathroom Gut Renovations
We strip to the studs and rebuild. For Highland’s 1960s and 1970s ranch homes, that often means replacing cast iron drain lines that have corroded after fifty years in alkaline alluvial soil. We spec shower pans with correct slope, install Hardie backer board behind tile, and terminate exhaust ventilation with wind-load-rated hoods that hold up to Santa Ana gusts. All work gets documented for your permit file, which matters later for insurance.
ADU Bathroom Construction and Finishing
Because Harvest builds the ADU shell and the interior, a bathroom inside a new Highland detached unit doesn’t require coordinating a second contractor. We rough in plumbing, set fixtures, tile, and handle the wind-load exhaust inspection as part of one permit package. For prefab ADUs from Dvele or Mighty Buildings, we complete the bathroom to spec so the unit is move-in ready without you managing trades.
Garage Conversion Bathrooms
Highland has a lot of older garages converted into living space, many from the 1980s without permits. When we add or remodel a bathroom inside one of these conversions, we first check what the assessor record shows versus what’s actually built. That discrepancy is the number one reason Highland garage conversion permits stall. We produce as-built drawings and work with the county to legalize or disclose the unpermitted work before bathroom rough-in begins.
Bathroom Plumbing and Drainage Correction
East Highland lots sit on alluvial fan slopes that don’t drain like flat valley floor parcels. We routinely find existing floor drains and shower pans that pool water because the original contractor ignored the site’s natural grade. We re-route drain lines, re-set pans with correct fall, and add cleanouts where mountain-storm debris flows could back up the system. This is a Highland-specific problem we’ve corrected on dozens of properties between Highland Avenue and the foothills.

Trusted Brands We Service in Highland
For Highland bathroom remodels, we specify products that hold up to inland heat, hard water, and wind-driven rain. We regularly work with Dvele and Mighty Buildings for prefab ADU interior finishing, and we install James Hardie backer board and exterior cladding because this climate demands moisture resistance that standard drywall can’t provide. We keep the common fittings, valves, and backer stock in rotation for Highland jobs, which shortens lead times when a supply house in San Bernardino or Redlands is backordered. The point is fast turnaround without substituting a lesser product.
Common Bathroom Remodeling Problems We See in Highland Homes
- Unpermitted 1980s garage conversions surfacing during plan review. A bathroom permit triggers a records check, and the assessor record often shows a two-car garage where living space now sits. We document and legalize before the bathroom scope moves forward, so your permit doesn’t die in review.
- Exhaust vents that fail Santa Ana wind-driven rain tests. Standard hoods let wind push moisture back into the wall assembly. We specify wind-load-rated terminations that pass inspection and prevent mold behind the tile.
- Drain lines sloped wrong on alluvial fan terrain. East Highland lots slope toward the mountains, and a shower pan or floor drain set level will pool water. We correct fall and add cleanouts where debris flows after mountain storms could clog the line.
- Moisture damage behind tile in older single-story tract homes. Homes built in the 1960s and 1970s often have no vapor barrier behind bathroom walls. We strip to studs and rebuild with cement board so Highland’s intense summer heat and wet winter storms don’t rot the framing.

FAQs – Bathroom Remodeling in Highland
Yes. Highland sits in a wind exposure zone at the base of the San Bernardino Mountains, and Santa Ana events push rain sideways through standard exhaust terminations. A compliant Highland bathroom permit requires a wind-load-rated exhaust hood tested for driven rain, typically rated at 110 mph or higher. We include these terminations in every ADU bathroom quote. Call (866) 538-0916 if you want to know whether your existing vent meets the standard.
Because the permit for the bathroom triggers a review of the entire property record. Many east Highland lots were subdivided from unincorporated county land, and unpermitted garage conversions or room additions from the 1980s show up on the assessor record only when a new permit is pulled. The bathroom scope can’t close until that existing work is documented and either legalized or disclosed. We handle that documentation as part of the remodel.
The slope at the foot of the mountains means drain lines need more careful fall than flat valley lots. We’ve seen shower pans set level that pool water after every use, and floor drains that back up after mountain-storm debris flows. We rough in plumbing to match the site’s actual grade, not a generic standard. If your ADU bathroom has recurring pooling, the drainage correction is a separate line item worth budgeting for.
A compliant quote includes the records review for unpermitted work on the main house, wind-load-rated exhaust termination, cement backer board behind all wet walls, drainage correction for alluvial-fan slope, and as-built drawings if the assessor record doesn’t match what’s built. A cheap quote skips several of these and you find out when the inspector red-tags the rough-in. Get the quote in writing and compare line items.
Documented compliance with wind-load and moisture standards gives your insurer proof that the bathroom was built to current code, which can reduce underwriting risk on a Highland property exposed to Santa Ana wind events. It also protects you if a storm damages the wall assembly, because the paperwork shows the vent and backer board were installed correctly. We provide the documentation at every inspection milestone. Call (866) 538-0916 for a quote that includes it.
