Fast, Reliable Bathroom Remodeling Across Highland
Bathroom remodeling in Highland, CA typically costs between $18,000 and $45,000 for a full tear-out, with wet-wall repairs and re-pipes adding $3,000 to $9,000 when old plumbing and framing show up behind the tile. Most jobs in the 92346 ZIP take three to six weeks, depending on what the tear-out uncovers. We’re Home Base ADU Builders, led by Neil Bradshaw, and we’ve remodeled enough 1960s – 1990s Highland tract bathrooms to know exactly what’s behind those walls before we write your contract. Call (866) 403-9834 for a free estimate, and we’ll walk your bathroom with you before quoting anything.
Why Home Base ADU Builders Is Highland’s Preferred Bathroom Remodeling Company
We work the full residential dwelling spectrum: ADUs, kitchens, and bathrooms. That’s the whole focus. We’re not a general contractor dabbling in remodels between commercial jobs. Neil Bradshaw built the company around one idea – match the homeowner to the right build, not the one we happen to stock. For bathrooms, that means the same brand-agnostic straight talk we bring to ADU construction. We’ll tell you when a full gut is overkill and when a surface refresh won’t survive Highland’s next wet season.
Highland homeowners call us because we’ve already solved the problems their house has. The tract homes between Base Line and the foothills, the ones built before 1990, share a DNA. Same undersized wet-wall framing, same missing pan liners, same galvanized stubs behind the shower valve. Our Bathroom Remodeling team has opened enough of these walls to quote them accurately before demo starts. That local pattern knowledge means fewer surprises on your change order, and when we do find something, the fix is already scoped from a dozen similar Highland jobs.
We carry James Hardie fiber-cement board on every project as standard backer for wet walls. It costs more than greenboard. We don’t care. Greenboard is what got a lot of Highland’s original bathrooms into trouble in the first place.
Our Bathroom Remodeling Services in Highland
The work below covers what actually comes up in Highland homes. Not every job needs all of it, but you should know what you’re looking at before the first tile comes off.
Full Bathroom Tear-Out and Permit-Driven Inspection
A full tear-out in Highland means opening walls to studs and floors to joists. That’s the only way to see what the 1970s left you. California code requires permits when you’re moving plumbing or altering framing, and the tear-out is what triggers the inspection. We pull the permit, schedule the inspection, and walk the inspector through. If the original shower has no pan liner – common in pre-1980s Highland tract baths – the inspector will flag it. You want that flag. We write the fix into the contract before demo day, so the inspection isn’t a surprise.
Wet-Wall Framing Repair and Re-Pipe
The wet wall is the wall behind your tub or shower valve. In a 1960s – 1980s Highland home, that wall is usually the one place water has been slowly winning for decades. Softened studs, galvanized supply lines nearly closed with scale, and copper stubs soldered where they shouldn’t be. We sister new framing next to compromised studs, replace galvanized runs with PEX from the wall out, and set blocking for grab bars and valve supports. If the framing doesn’t pass, nothing else matters. We fix it first, photograph it, and get your sign-off before closing the wall.
Shower Pan Liner and Cement-Board Waterproofing
Pre-1980s Highland baths rarely have a proper pan liner. The tile was set directly on greenboard or a mud bed with no membrane, and it held until it didn’t. When we rebuild a shower, we install a PVC pan liner over a pre-sloped mortar bed, run cement board to the ceiling on all wet walls, and tape and seal every seam. That’s not an upgrade; it’s the minimum. On homes near the foothill bench where drainage slopes toward the wash, we detail the pan with an extra weep-hole test before tile goes in. Water moves downhill in Highland. Your shower needs to let it.
Fixture and Valve Replacement with Scald-Guard Compliance
Older single-handle valves without pressure-balance or thermostatic mixing are common in Highland’s original baths. If you’ve ever been scalded when someone flushes a toilet, that’s the valve. Code requires anti-scald protection now. We replace valves with pressure-balance units, bring supply lines to current sizing, and check for the galvanized-to-copper transition hidden in the wall. That transition is where scale builds worst on Highland’s hard water. A new valve on a half-closed galvy stub won’t give you the pressure you paid for. We cut it back and re-pipe as far as needed to get decent flow.

Trusted Brands We Service in Highland
Our remodeling work on Highland bathrooms ties into the same material standards we use on ADU builds. James Hardie fiber-cement backer board is standard on every wet wall we open. For larger bathroom additions or conversions connected to an ADU, we work with Tuff Shed structures where the bathroom lives inside a converted or detached shell, and we’ve incorporated Mighty Buildings panels on bigger projects. We’re comfortable across the full budget range, from a 1970s hall bath re-pipe to a full primary suite addition. Same team, same permit discipline.
Common Bathroom Remodeling Problems We See in Highland Homes
- Original tile set directly on greenboard. The surface looks intact until the grout starts crumbling and the wall moves when you lean on it. There’s no vapor barrier behind most of these, which means the studs have been absorbing moisture for forty years.
- Galvanized-to-copper transitions in the wet wall. That transition point is where hard water scale closes the line down. We regularly cut out fittings that have shrunk from half-inch to pencil-width inside.
- Framing softened at the shower pan. Slow seep over decades leaves studs that flex under load, bottom plates that nail won’t bite into, and subfloor that needs sectioning out. This is where Highland’s sandy alluvial soil matters: slab foundations here settle, tubs move, and sealant cracks follow.
- No scald guard on original valves. Single-handle Moen or Delta valves from the 1970s and 1980s were built before pressure-balance code. They work fine until someone flushes, and then the temperature swings hard. A new valve is a code issue if you’re pulling the wall open.
One job on the foothill bench north of Base Line comes to mind, where lots back toward the wash. A homeowner called us after a bedroom closet floor sponged up water every time the hall bath was used. Pulling the tub surround, our tech found the original 1970s tile set directly on greenboard with no vapor barrier, a copper stub soldered to galvanized that had nearly closed off, and framing at the wet wall softened a half-inch from years of slow seep. We stopped, photographed everything, wrote the reframe and re-pipe as a signed change order before demolition continued, and the finished bath now has a proper pan liner, a pressure-balance valve, and cement board to the ceiling.
Pricing for Bathroom Remodeling in Highland, CA
For a full tear-out bathroom remodel in Highland, a standard 5×8 hall bath runs $18,000 to $28,000, including permits, new tub or walk-in shower, tile to ceiling, vanity, toilet, fixture replacement, and paint. A primary bath with a larger footprint, double vanity, custom tile, and a curbless shower runs $30,000 to $45,000. Wet-wall re-pipe and framing repair, when needed, typically adds $3,000 to $9,000 depending on how much galvanized we’re replacing and how many studs need sistering. These are Highland numbers – labor rates here are close to neighboring San Bernardino and Redlands, but Highland’s older tract stock means re-pipes come up more often than in newer Loma Linda builds. Call (866) 403-9834 for an exact quote. Estimates are free, and we write allowances into every contract so a surprise behind the wall never becomes an unreported cost.

FAQs – Bathroom Remodeling in Highland
Yes, if you’re moving plumbing, altering framing, or changing the shower pan, a permit is required by San Bernardino County and the City of Highland. A cosmetic refresh – new vanity, fixture swap, paint – typically doesn’t require one. Call (866) 403-9834 to talk through your specific scope, and we’ll tell you honestly whether a permit is in play.
The most common finds are missing shower pan liners, greenboard behind old tile with no vapor barrier, galvanized-to-copper transitions half-closed with scale, and framing softened from decades of slow seep. Homes built before the 1980s in Highland didn’t have the pan-liner and pressure-balance code we have now, so these are routine, not rare.
Every contract includes written allowances for the common unknowns: re-piping a wet wall, sistering framing, and installing a pan liner where one was missing. When we open the wall and find something outside the allowance, we stop, photograph it, and get a signed change order before work continues. Nothing gets done on a verbal “we’ll deal with it later.” Call (866) 403-9834 for a free estimate and we’ll show you exactly how the allowance structure reads.
Indirectly, yes. Highland sits in San Bernardino County’s hot, wildfire-prone foothill zone, so any exterior wall we open has to meet current fire-resistant construction standards. That usually means fire-rated sheathing and sealant details at exterior penetrations. Inside, the bigger issue is ventilation: Highland’s triple-digit summers mean a bathroom fan that can’t move enough air will grow mold fast. We spec fans at higher CFM and check attic venting on every job.
It can. Highland’s foothill-bench lots sit on sandy alluvial soil, and slab foundations settle over time. We’ve pulled tubs and found a slab crack running straight under the wet wall where water had been following it for years. Drain lines in 1960s – 1980s tract homes are cast iron and often scaled or bellied. If we find it, we scope the repair and get approval before moving on. That’s the point of a permit-driven tear-out: you find it now, not after tile goes down.
