Fast, Reliable Bathroom Remodeling Across Highland
Bathroom remodeling in Highland, CA typically runs $9,000 – $28,000 depending on the age of the home, the condition of what’s behind the walls, and whether you’re doing a full gut or a surface refresh. We plan every job on the assumption that a 1950s – 80s slab-on-grade house has surprises waiting behind the tile, so we price with allowances and write the change-order process into the contract before demo day. That’s how you get a remodel without the number moving on you mid-job. Call (936) 259-2607 for a free estimate from Penhallow Remodeling.
We work in Highland every week, from the tracts along Base Line Road up through the foothill neighborhoods north of 5th Street. Our crews know what East Highlands homes look like when the walls come open. Trevor Nash leads every Highland project personally, and every estimate is written, not verbal.
Why Penhallow Remodeling Is Highland’s Preferred Bathroom Remodeling Company
Highland homeowners have been burned before, and usually by the same two things: a price that ballooned after demo, and a contractor who stopped answering the phone. We handle both problems with a written price before any work starts and a 365-Day Done Right Promise in writing on every project. If the work fails inside the guarantee period, we come back and fix it at no charge. That promise is printed on every contract, not implied.
Our technicians are background-checked and arrive in uniform. You know who’s walking into your home. A live person answers our phone 24/7, not a voicemail maze and not a call center. When a Highland homeowner calls at 7 a.m. on a Saturday with a question about a permit sign-off, a real person picks up.
We’re part of the Kingswell family of companies, operating under The Kingswell Way since 2004. Each location is independently owned and operated. The standard that matters for Bathroom Remodeling in Highland is simple: say the price before the work, show up in the window we gave, leave the place cleaner than we found it.
Tub to Shower Conversion in Highland
Tub to Shower Conversion in Highland is the single most common project we do in the 1960s and 70s tract homes along Highland Avenue and Base Line Road. A tub-to-shower conversion in Highland runs $3,500 – $10,000 depending on the condition of the wet-wall framing, the shower valve rough-in, and whether the home needs a new drain location cut into the slab.
Here’s what that job actually involves in a Highland slab-on-grade home. We pull the tub, open the wet wall, and look at what’s behind it. In too many of these houses, the original framing has rotted at the base plate where decades of slow tub-surround leaks wicked into the wood. If the framing is bad, we write the repair as a change order with an allowance credit. You approve it in writing before we cut anything.
Slab Conditions and Drain Relocation
Moving a drain in a slab floor is where Highland’s geology shows up. The alluvial soils under the northern tracts heave with moisture cycles, and we regularly see slabs that have moved a half-inch under an old tub pan. We core the slab, check the subgrade, and set the new drain to a corrected level before the shower pan goes in.
Shower Valve and Rough-In Upgrades
Opening the wall trips current California code for GFCI protection, exhaust ventilation, and rough-in venting. We plan for that in the allowance, and we pull the permit so the inspection sign-off is on the record. You don’t want a shower valve that doesn’t meet code and a home sale that hits a snag later.
One Day Bath Remodel in Highland
One Day Bath Remodel in Highland is a real option when the scope is contained: a shower surround replacement, a vanity swap, a new toilet and fixtures, or a tub-to-shower conversion where the framing is still sound and the slab doesn’t need drain relocation. A contained one-day bath remodel in Highland typically lands in the $4,500 – $12,000 range for a walk-in shower package and $3,500 – $10,000 for the tub-to-shower conversion.
The word “one day” means one install day after demolition and prep are done. We don’t rush through waterproofing to hit a clock. The dry time on the waterproofing membrane matters more than the install speed. But for a Highland homeowner who has one bathroom and can’t be down for a week, the sequencing matters.
What Fits in a Single Day
A one-day job works when the wet-wall framing is intact and the existing shower footprint doesn’t change. We show up with the materials pre-cut, the waterproofing system staged, and the permit already pulled. The crew gets the demo, the new shower base, the walls, the valve trim, and the cleanup done in one long day.
What Doesn’t Fit
If we open the wall and the framing is rotted, the one-day plan becomes a two-day plan. That’s not a bait-and-switch. It’s what the house decides. And it’s exactly why we write the allowance line and the change-order process into the contract before we start. You know what happens if the house has a problem.
Trusted Brands We Service in Highland
We install fixtures and materials from brands that carry their own warranties alongside ours. Kohler and Moen valves, Delta and Grohe rough-ins, Cambria and Silestone quartz for vanity tops, KraftMaid and Wellborn cabinetry where the vanity is built-in. We also work around existing systems from Abodu and Cover where Highland homeowners have accessory structure plumbing that ties into a bathroom group. Sourcing is coordinated from our Inland Empire office, so parts turnaround for Highland jobs is measured in days, not weeks.
Common Bathroom Remodeling Problems We See in Highland Homes
- Rotted wet-wall framing at the base plate: Decades of slow tub-surround leaks wick into the 2x4s. By the time we open the wall, the bottom plate is soft and the wall has to be rebuilt before tile goes on.
- Slab heave under the old shower pan: Expansive alluvial soils under Highland’s slab-on-grade tracts push and settle with moisture cycles. We see pans cracked at the corners and floors that slope the wrong way.
- Failed 1970s waterproofing behind tile: Older Highland bathrooms often have tile set on drywall with no moisture barrier behind it. The grout fails, water gets in, and the studs rot from the inside out.
- Code triggers once walls are open: Opening a wall in Highland means the bathroom now has to meet current California code for GFCI, exhaust, and venting. The permit and inspection sign-off add scope that a no-permit quote never accounts for.

What moves the number is what’s behind the walls. A 1968 ranch with rotted framing, slab heave, and a bathroom that hasn’t been touched since Nixon will land at the higher end. A 1990s home with dry framing and a contained footprint lands lower. Every estimate comes with an allowance line for framing and waterproofing, and every change order gets your written approval before we cut. Call (936) 259-2607 for a free written estimate.

FAQs About Bathroom Remodeling in Highland
Because we know what’s behind the walls of a 1950s – 80s slab-on-grade Highland home before we open them, and we want you to know too. The allowance line is a pre-approved dollar amount set aside for framing repair and waterproofing correction if the house needs it. If we don’t touch the allowance, that money comes off the invoice. Call (936) 259-2607 and we’ll walk you through a sample contract line by line.
Yes. Any remodel that moves a drain, opens a wall, or touches electrical in Highland requires a permit from the city, and the rough-in inspection happens before we close the wall. We pull the permit, schedule the inspection, and the sign-off is on the record. A contractor telling you no permit is saving their own schedule, not your home sale.
Yes, and we do them routinely. The slab-on-grade construction means the drain stays where it is or gets cored and reset to a corrected level if the slab has heaved. The bigger question is the wet-wall framing. If it’s rotted, we write the repair as a change order with an allowance credit and you approve it in writing before we cut. For an exact number on your Highland home, call (936) 259-2607 for a free estimate.
A contained one-day bath remodel in Highland is one install day after demo and prep. That’s realistic for a shower surround replacement, a vanity swap, or a tub-to-shower conversion with sound framing and no drain relocation. If the wall opens up and the framing is bad, the job becomes two days. We price both scenarios in the contract so the schedule doesn’t surprise you.
An allowance is money pre-approved in the contract for a specific category of work, like framing or waterproofing. A change order is a written document that identifies work outside the original scope, states the cost, and requires your signature before we proceed. In Highland, where slab heave and rotted wet walls are common, we use both so the final number is never a surprise. Call (936) 259-2607 for a written estimate that includes both lines.
