Fast, Reliable Bathroom Remodeling Across Highland
Bathroom remodeling in Highland typically costs $14,000 – $38,000 depending on whether you’re updating a guest bath inside a 1960s ranch home or adding a full bathroom to a detached ADU on an acreage lot. Most projects in the 92346 zip code take two to five weeks once permits clear. We know Highland’s building department, its wildfire zone rules, and its older housing stock well enough to quote accurately the first time. Call (844) 934-0236 and we’ll walk your property and give you a written estimate.
Our Bathroom Remodeling team has worked on homes from Base Line Road to the East Highlands, and we understand what a half-acre lot with a 1950s septic system demands. That’s not theoretical. If you’re planning a bath remodel in Highland, we’ll help you avoid the mistakes we’ve seen cost homeowners months of delay.
Why Newport Beach ADU Builders Is Highland’s Preferred Bathroom Remodeling Company
Highland has a particular kind of housing stock: post-war single-story ranch homes on big lots, with detached garages and sheds that have been converted or half-converted over the decades. Many of those conversions happened without permits. That matters because a bathroom remodel that touches one of those structures can either legalize it or trigger an order to tear it down. We’ve handled enough Highland projects to know which path you’re on before you spend a dollar.
We also know the CAL FIRE defensible-space rules that govern any remodel that alters a building envelope in Highland. If your project adds square footage or changes exterior walls, you’ll need ember-resistant vents and roofing. In San Bernardino or Redlands, those same rules don’t apply to the same degree. We scope this into every Highland quote so the inspection doesn’t surprise you.
One contractor from permit to punch-list. That’s how we work in Highland, and it’s why homeowners here hire us for bathrooms when they could call a generalist closer to home. The estimate we give you accounts for the city’s actual requirements, not a generic California template.
Our Bathroom Remodeling Services in Highland
Full Bathroom Replacement
Gutting and rebuilding a bathroom inside a Highland ranch home usually runs $18,000 – $32,000. That includes new tile, a tub or shower pan, vanity, lighting, and plumbing fixtures. Homes built here in the 1950s and 1960s often have cast-iron drain lines that have corroded at the joints, so we include a camera inspection of the waste line before we quote. Replacing a section of rusted cast iron under a slab can add $2,500 – $6,000, and you want to know that before demolition starts, not after.
Bathroom Additions for ADUs and Detached Structures
Adding a bathroom to a detached ADU on a Highland acreage lot runs $22,000 – $45,000 depending on how far the sewer or septic line has to run and whether the existing structure was permitted. If the building is an unpermitted converted garage, the first step is a meeting with the city building department to confirm legal nonconforming status. We do this before you commit to a design, because it changes the scope entirely. On one half-acre lot off Base Line Road, we converted an unpermitted detached garage into an ADU with a full bathroom. We verified the legal nonconforming status first, replaced the old electrical panel, and installed a James Hardie exterior wall system with ember-resistant vents. The bathroom passed inspection without triggering a demolition order, and the owner got a fully legal second dwelling.
Walk-In Shower Conversions and Tub-to-Shower Retrofits
For older Highland residents who want to stay in their homes, a tub-to-shower conversion costs $9,000 – $16,000 and typically takes about a week. We install low-threshold pans, grab bars, and slip-resistant tile. On 1970s slab-on-grade homes, the drain relocation can be the tricky part, and we’ll tell you in advance whether your slab will require a chip-and-patch drain move or whether the existing tub drain can be reused.
Small Bath and Powder Room Updates
For a guest bath or powder room in a Highland home, expect to spend $8,000 – $14,000. That covers a new vanity, toilet, flooring, paint, and a mirror or light fixture upgrade. If your home still has the original 1960s galvanized supply lines, we’ll recommend repiping that section before the walls close, and we’ll show you the actual cost on the estimate rather than burying it in allowances.

Trusted Brands We Service in Highland
We’re not tied to a single product line, which means the fixtures and materials in your Highland bathroom can come from brands that fit your goals, not what one vendor is trying to move this quarter. We work with James Hardie fiber-cement for exterior wall systems when a remodel touches an ADU envelope, and we source plumbing fixtures and surfaces from a range of manufacturers suited to both budget and design goals. Boxabl and Plant Prefab are part of our larger ADU work, but in the bathroom itself, what matters more is that we stock and source locally so a fixture order doesn’t hold up your Highland inspection for three weeks.
Common Bathroom Remodeling Problems We See in Highland Homes
- Unpermitted outbuildings. Many Highland properties have detached garages or sheds converted without permits, and adding a bathroom to one of these without verifying legal nonconforming status can trigger a demolition order. The right first step is confirming the building’s status with the city before you design anything.
- CAL FIRE ember-resistant requirements. If a bathroom addition or remodel changes the exterior envelope of a building in a wildfire zone, you’ll need ember-resistant vents and possibly roofing upgrades. These requirements don’t appear on generic bathroom quotes, but they’re routine in Highland, and failing them means a red-tagged inspection.
- Septic and well setbacks on acreage lots. Adding a bathroom to a structure on a Highland lot with a septic system means meeting minimum clearances from the septic tank, leach field, and well. If the bathroom drains are planned too close, the health department will force a redesign. We measure setbacks before quoting.
- Corroded cast-iron and old galvanized pipe. Highland’s 1950s-1970s housing stock is full of cast-iron waste lines and galvanized supply pipes that have reached the end of their life. A bathroom remodel is the right time to replace them, but that work needs to be in the estimate up front, not discovered after the walls come down.

FAQs – Bathroom Remodeling in Highland
Yes, often you can, but only if the city confirms the structure has legal nonconforming status. The first step is a review with the Highland building department, and we handle that for you. If the building has that status, a bathroom remodel can proceed without a demolition trigger. If it doesn’t, the city may require the whole structure to come down, and you want to know that before any design money is spent. Call (844) 934-0236 and we’ll check the status as part of the estimate.
In Highland, any bathroom remodel that changes the exterior envelope of a building requires ember-resistant vents and, in many cases, upgraded roofing materials to meet CAL FIRE defensible-space rules. In San Bernardino, the same project might not face those requirements. We scope the wildfire-zone work into every Highland quote so your inspection passes the first time. Estimates are free.
On a septic system, the bathroom drains and any new structure footprint have to maintain specific distances from the septic tank, leach field, and well. If the addition encroaches, the county health department won’t approve the permit, and the whole design has to move. We measure setbacks before we draw the plan, which keeps the price honest and the permit moving. Call us for a property-specific answer.
Yes, many Highland sheds can be converted into an ADU with a full bathroom, provided the structure is sound and the city confirms its status. We’ve done this on half-acre lots off Base Line Road, and the bathroom itself typically runs $22,000 – $38,000 depending on sewer distance, electrical upgrades, and exterior wall work. The first step is checking the structure’s legal status with the building department. We’ll do that for you.
Flat lots in Highland drain slowly in winter, and a bathroom remodel that ties into existing plumbing can expose standing-water issues near the foundation. If your lot pools during December and January rains, we’ll account for drainage when we scope the project, because it affects where vent lines and exterior wall penetrations can go. This is routine for us in Highland. Call (844) 934-0236 and we’ll inspect the lot before we quote.
