Fast, Reliable Bathroom Remodeling Across Highland
Bathroom remodeling in Highland typically runs $18,000 to $42,000 for a full gut-and-replace, and most projects take 3 to 6 weeks once permits clear. We work throughout the 92346 ZIP code, from the ranch neighborhoods off Base Line up to the foothill lots near Greenspot, and we know what these homes hide behind their walls. If you own a 1950s to 1980s Highland home, your bathroom remodel will almost certainly turn up something the previous owner never pulled a permit for. Call us at (866) 730-4828 and we’ll walk the site before you commit to anything.
Why Bungalow ADU Builders Is Highland’s Preferred Bathroom Remodeling Company
We’re not a general contractor that takes bathroom remodels as filler between bigger jobs. Bathroom Remodeling is a core line of work for us, handled by the same team that builds finished, rentable ADUs with real kitchens and baths. That matters in Highland specifically because so many homes here have aged plumbing, unpermitted additions, and wiring that hasn’t been touched since Eisenhower was in office. We know what a 1960s ranch off Highland Avenue is likely to show us once the tile comes up, and we price for it honestly from the first conversation.
Led by Nate Calloway, our crew has opened enough Highland bathroom walls to know that surprises are the norm, not the exception. Homeowners tell us the same thing over and over: they got a quote from someone who never mentioned what a code inspection would require, and then the price moved mid-job. We don’t work that way. We inspect first, document what we find, and get written approval before any change order adds cost.
For Bathroom Remodeling in Highland, response time matters. We schedule site walkthroughs within a week of your first call in most cases, and we’ll give you a line-by-line written estimate that separates known work from anticipated allowances.
Our Bathroom Remodeling Services in Highland
Inspection-First Bathroom Remodels
We don’t write a final quote for a Highland bathroom until we’ve opened the access panel, checked the subfloor from below if possible, and looked at the electrical panel. Homes built between the 1950s and 1980s in this city frequently have original 60-amp or 100-amp panels, ungrounded wiring, and framing that was never designed for the weight of modern tile systems. This is why we build an inspection step into every estimate. It keeps the number on paper honest, and it keeps you from finding out about a $4,000 rewire after demolition is already done.
Written Change-Order Process
Anyone who has remodeled an older home knows the pain of verbal “by the way” add-ons that show up on the final invoice. Here’s how we handle it: every unexpected condition gets photographed, documented, and priced as a written change order. You see the number, you approve it in writing, and then we proceed. No “we figured you’d want us to just fix it.” That discipline is especially important in Highland, where unpermitted additions and original systems routinely create conditions no contractor can see before walls are open.
Code-Upgrade Compliance for Older Homes
When we open a wall and find ungrounded wiring, undersized circuits, or framing that doesn’t meet current shear requirements, the city of Highland will require upgrades before we can close the wall and pass inspection. We handle that work in-house where it falls within the remodel scope, and we coordinate directly with city inspectors. What this means for you: the remodel doesn’t stall for weeks while you hunt down an electrician or a structural engineer. Nate Calloway and the team keep the job moving.
Waterproofing and Subfloor Repair
Failed waterproofing is the most common hidden condition in Highland bathrooms. Original lead pans under 1970s slab-on-grade floors corrode, and water seeps into the subfloor for years before anyone notices. We remove the old pan, replace damaged framing or slab sections, and install modern waterproofing systems that meet current California code. This is not a spot-fix job. If the pan failed, the area around the drain usually failed too.

Common Bathroom Remodeling Problems We See in Highland Homes
- Ungrounded or knob-and-tube wiring behind tile: Many homes in Highland have never been fully rewired. When tile comes off, we routinely find cloth-wrapped wire with no ground. A full circuit upgrade for the bathroom is often required by the city before we can pass inspection.
- Failed cast-iron drains and lead pans under slab: Original plumbing from the 1960s and 1970s is at the end of its service life. Leaks have usually already begun, which means concrete demolition and re-piping. We price this as an allowance in every slab-on-grade remodel.
- Unpermitted additions sharing a bathroom wall: If a previous owner added a room without permits, the shared wall may not meet current fire and egress separation standards. Opening the bathroom triggers compliance for that wall assembly.
- Drainage issues on sloping lots off Base Line and Greenspot: Some Highland foothill lots slope gently but lack proper site drainage. When a bathroom remodel moves plumbing, the city may require a drainage review. We coordinate with the city so this doesn’t become a project-killer.
Trusted Brands We Source for Highland Projects
Because our core business is ADU construction, we work with a defined roster of product systems that the industry actually respects. For bathroom remodels in Highland, that means we source plumbing fixtures and finishes with the same discipline: brands we know hold up under hard water and heavy use. On the ADU side, we’re brand-agnostic across providers like Boxabl, Plant Prefab, and Tuff Shed, so if your remodel is part of a larger ADU build, we can compare systems rather than pushing one option. For exterior work tied to an ADU, we specify James Hardie fiber-cement siding, which handles Highland’s hot dry summers and Santa Ana winds better than cheap cladding. For the bathroom itself, we don’t lock you into a single fixture line. We match the product to your budget and the home’s age.
Pricing for Bathroom Remodeling in Highland, CA
Here are the numbers we actually see in Highland, not national averages. A cosmetic update that keeps the existing floor plan, a guest bath with new tile, vanity, and toilet: $12,000 to $18,000. A full hall bathroom remodel with new waterproofing, shower or tub replacement, new fixtures, and code upgrades: $22,000 to $35,000. A primary bathroom with expanded shower, custom glass, moving plumbing, and structural work: $35,000 to $55,000. The biggest cost driver in Highland is not the tile or the vanity. It’s what we find when the walls come open. Our written allowances for rewiring, subfloor repair, and drain replacement are based on what we’ve documented in comparable Highland homes, not a national square-footage formula. Call (866) 730-4828 for a site-specific estimate. Estimates are free, and the allowance structure means the first number you see includes the likely surprises.
Highland’s Older Homes: What a Bathroom Wall Actually Turns Up
Because many Highland homes were built between the 1950s and 1980s with original electrical panels and unpermitted additions, opening bathroom walls often reveals undersized wiring and framing that must be brought up to current code before the remodel can proceed. This is the single biggest reason a remodel quote moves. On a ranch home off Base Line, our crew opened a hall bathroom wall and found original 1950s wiring with no ground and a slab that had been poured over an old floor drain, causing failed waterproofing. We documented the issues with photos, priced the rewiring and slab repair as a written change order, and got approval before proceeding. The homeowner later told us the change order process was the reason they slept at night during the project.
This is not rare in Highland. It’s typical. Homes in the 92346 ZIP code, especially the single-story ranches south of Greenspot and the lots along Highland Avenue, were built when 60-amp service and ungrounded circuits were code-compliant. Today, the city requires GFCI protection for all bathroom outlets, dedicated circuits for certain fixtures, and modern bonding. When we open a wall and the wiring is original, the code path is non-negotiable. We handle it with an allowance written into the contract, priced from the first estimate, not hidden until the middle of the job.
Unpermitted additions complicate this further. If someone in the 1980s added a bedroom without a permit and that room shares a wall with your bathroom, the shared wall assembly must be brought up to current fire separation standards once we open it. That can mean adding a layer of drywall, re-framing, or upgrading the egress window in some cases. We flag this in the inspection phase whenever we can identify it from the outside or from attic access. If we can’t see it until the wall is open, the change-order process applies: photos, written price, your signature, then work proceeds.

FAQs – Bathroom Remodeling in Highland
Expect that opening bathroom walls will reveal ungrounded wiring or cloth-wrapped cable, and expect the city to require a circuit upgrade before we close the wall. We price this as a written allowance in your initial estimate, so it’s visible from day one. Call (866) 730-4828 if you want us to check your panel before you plan the project.
When we identify an unpermitted addition sharing a wall with your bathroom, we document it, determine what current code requires for that shared wall assembly, and price the upgrade as a written change order before we proceed. We don’t start the affected work until you’ve approved the number in writing.
Many homes in the foothill neighborhoods off Base Line and Greenspot sit on gently sloping lots where drainage was never properly addressed. If your remodel moves plumbing or changes the footprint, the city may require a drainage review to ensure runoff doesn’t create problems for the structure or the neighbors. We coordinate that review directly with the city.
Unexpected repairs are priced as written change orders. We photograph the issue, explain what code requires, and give you a line-item price. You approve it in writing, and then we proceed. No verbal “we’ll figure it out later” and no end-of-job lump sum surprise.
Yes. Code upgrades are part of most Highland bathroom remodels, especially in 1950s to 1980s ranch homes. We handle rewiring, GFCI protection, framing corrections, and waterproofing upgrades within the remodel scope, and we coordinate inspections with the city of Highland.
