Fast, Reliable Bathroom Remodeling Across Highland
A full bathroom remodel in Highland typically runs $18,000 to $45,000 depending on whether you’re refreshing a hall bath or gutting a primary suite, and most permits take two to four weeks before demo starts. We work throughout the 92346 zip code, from the older east-side tracts off Base Line to the newer subdivisions near Greenspot Road, and our crews know exactly what opening up a 1950s-1980s Highland home turns up. If you’re planning a bathroom remodel and want straight answers on pricing, code upgrades, and what the city will ask for before the walls go back up, call us at (877) 265-5812. Nelson Ybarra leads our team, and he’s walked enough Highland remodels to know the difference between what a quote says and what the work actually requires.
Why Orange ADU Builders Is Highland’s Preferred Bathroom Remodeling Company
We’re not a general contractor sporadically taking bath jobs. Our company focuses on ADUs and interior remodels, which means every bathroom we open in Highland gets the same rigor we’d apply to a permitted accessory dwelling unit. That matters here because Highland’s building department is particular about documentation, and a remodel that changes fixture loads or moves drains needs a permit that actually gets inspected, not waved through. Homeowners in the East Highlands and along Victoria Avenue have learned that a remodeler who doesn’t know local submittal quirks costs them weeks.
Our reputation in Highland is built on what happens after the estimate. When we price a bathroom on a 1960s tract home near Highland Avenue, we include written allowances for the wiring, framing, and waterproofing repairs that older walls hide. We don’t make the homeowner guess. That’s why much of our Highland work comes from referrals, neighbors who watched a project finish on the number we quoted rather than balloon at the end.
We also carry the broader construction knowledge most bath-only contractors lack. Orange ADU Builders works across leading prefab systems like Abodu, Cover, and Dvele, along with site-built ADUs, James Hardie exteriors, and Tuff Shed structures. When a Highland homeowner wants to remodel a bath now and add an ADU next year, we can plan the panel capacity, drain routing, and water-heater load with both projects in mind, so the bath remodel doesn’t box in the future unit.
Our Bathroom Remodeling Services in Highland
We handle the full range of bathroom work Highland homes need, from cosmetic updates to full gut-and-reframe jobs. Here’s what we do most often in this area.
Full Bathroom Remodel With Permit-Triggered Code Upgrades
A complete gut of a Highland bathroom means pulling a permit, and a permit means the inspector sees what’s behind the tile. On homes built before 1990, that usually triggers GFCI circuits, a vent fan upgrade, and sometimes a main-panel service increase if the existing panel is already near capacity. We write those allowances into the contract up front, so when the electrician confirms the panel needs work, the price doesn’t change mid-project. We also handle the septic abandonment step on east-side lots before we ever start the finish work.

Shower Waterproofing and Tile Rebuild
Highland’s older tract homes almost always show waterproofing failure once the original shower tile comes off. The 1950s-1980s mortar beds and green board behind that tile were never built to modern standards, and the result is mold, dry rot, and framing damage you can’t see until demo. We rebuild showers with modern waterproofing membranes, proper slope, and tile rated for Highland’s hard water, which runs through most homes in the 92346 area. It’s not a quick patch, it’s a waterproof assembly that lasts.

Vanity and Drain Relocation With Slab Work
Moving a vanity or tub drain on a Highland slab home means cutting concrete, and Highland’s sandy alluvial soils near the Santa Ana River make that cut more involved than it looks. The ground under many slabs is poorly consolidated and can be saturated, so a new drain penetration needs proper patching and sometimes a compacted fill rather than a quick bag of mix. We’ve done enough of these on Highland lots to plan for the soil condition before we cut, not after.

Accessibility and Aging-in-Place Updates
Plenty of Highland homeowners are keeping parents or grandparents in the house rather than moving them to assisted living. That means curbless showers, grab bars, wider door openings, and vanities at wheelchair height. We build these so they don’t look institutional, using tile and fixtures that feel like a designed bath, not a hospital room. Highlands’ stock of single-story ranch homes makes many of these conversions straightforward since there’s no stair case to work around.

Common Bathroom Remodeling Problems We See in Highland Homes
- Failed waterproofing behind original tile: Homes built from the 1950s through the 1980s in Highland almost always used cement board or green board that breaks down after 30-plus years. The damage only shows once the wall is open, which is why a quote built without opening anything will move when the tile comes off.
- Undersized main panels: Many Highland homes still run on 100-amp panels that were fine when the house had one bathroom and a window AC. Add a GFCI circuit, a heated floor, or an electric bidet seat, and the panel is over capacity, triggering a service upgrade after demo, not at estimate.
- Slab penetrations in sandy alluvial soil: Near the Santa Ana River corridor, Highland’s ground under the slab can be loose and wet. A relocated shower drain cut through that material needs engineered patching and proper compaction, not a bag of concrete from the hardware store.
- Un-abandoned septic systems on east-side lots: Some Highland homes on the east side were connected to city sewer years ago but the original septic tank was never documented as abandoned. The city requires that abandonment before final sign-off on permitted work that changes fixture loads, and it’s a step most out-of-area remodelers have never encountered.

FAQs – Bathroom Remodeling in Highland
Because on Highland’s 1950s-1980s tract homes, once the tile comes off, the walls almost always reveal something that has to be fixed before the permit will close. That might be cloth-wrapped wiring feeding the vanity, framing notched past half its depth for the old drain, or dry rot where water leaked behind the shower. The allowance is our way of telling you up front what those repairs will cost, so the job doesn’t surprise you mid-way. Call (877) 265-5812 and we’ll show you what a Highland-specific allowance looks like in writing.
Only if your lot is on Highland’s east side and was connected to city sewer without the original septic tank ever documented as abandoned. The city requires that abandonment before final inspection on permitted work that changes fixture loads. We check this early in the process so it doesn’t stall your project. Call (877) 265-5812 for an exact determination on your lot.
Cloth-wrapped wiring, framing compromised by old plumbing, and waterproofing that failed behind the original tile years before the current homeowner bought the place. On a 1962 tract home off Base Line, our crew opened a hall bath wall to move the tub drain and found all three, plus a panel already near capacity. We pulled a permit, wrote repair allowances into the contract, and got the homeowner’s written approval on every line before touching the framing. That’s the standard on Highland remodels, not the exception.
Yes, and it’s one area where planning ahead saves real money. If you’re adding a bathroom fixture or a heated floor, the panel load increases. If an ADU is coming later, the panel should be sized for both at the same time, not upgraded twice. We plan Highland bath remodels with the ADU’s electrical and drain needs in mind, since Orange ADU Builders handles both scopes. Call (877) 265-5812 to talk through your lot before you commit to either project.
We cut the slab, inspect the underlying ground, and if the soil is loose or saturated, we place proper compacted fill and an engineered patch rather than a quick pour. Highland’s alluvial soils near the Santa Ana River don’t behave like the clay you find in other parts of the Inland Empire, and a shower drain set in unstable ground will shift and leak over time. Call (877) 265-5812 for a site-specific evaluation of your slab.
