Fast, Reliable Bathroom Remodeling Across Highland
A full bathroom remodel in Highland typically runs $18,000 – $42,000 for a standard 5×8 hall bath, and $28,000 – $65,000 for a primary bath with a walk-in shower or soaking tub. Most projects take 3 – 6 weeks once demo starts, depending on what we find behind the walls. That last part matters more in Highland than almost anywhere else we work. If you’re planning a remodel in the 92346 ZIP, call (877) 658-7475 for a free estimate, and we’ll walk you through what your specific home is likely to need.
Why Casita ADU Builders Is Highland’s Preferred Bathroom Remodeling Company
We’re an ADU specialist first, which means we live in the world of compact, code-heavy, inspection-driven construction. A bathroom is the most permit-intensive room in a house, and our team treats every Highland remodel with the same rigor we apply to a new detached unit. Nolan Treffert leads our crews, and the standard is simple: if we wouldn’t put it in a new build, we don’t put it in your remodel.
Highland’s stock of mid-century stucco tract homes and newer east-side subdivisions is exactly what we see when we work on Bathroom Remodeling projects alongside ADU builds. Older hall baths hide galvanized supply lines and failing shower pans. Newer homes hide builder-grade fixtures that fail under Highland’s hard water. We know what to look for before we ever open a wall, and that’s why our estimates hold up better than a flat-rate quote from a generalist.
Our Bathroom Remodeling Services in Highland
Full Bathroom Remodels
We handle everything from gut-and-replace remodels of 1960s hall baths on Highland’s original tract lots to primary bath expansions in the newer subdivisions east of the 210. Each project starts with an inspection of what’s behind the tile and below the pan. On Baseline Road homes, that often means finding galvanized pipe that needs a PEX re-pipe, and we write that into the scope before demo begins, not after.
ADA-Compliant Conversions
Highland’s aging housing stock means many homeowners are planning for parents or for their own long-term mobility. We build curbless showers, grab-bar blocking, comfort-height vanities, and wider door openings to meet California ADA standards without making the room feel institutional. These conversions fit naturally with the multigenerational ADU projects we handle across the Inland Empire.
Water Treatment Integration
This is the piece most Highland remodels skip, and it’s the one that costs homeowners later. Mineral-heavy municipal and well water across the 92346 ZIP builds scale inside valves, cartridges, and supply lines faster than you’d expect. We plan for a softener loop and, where needed, whole-house filtration as part of the rough-in, not as an afterthought. If you’re already opening walls, the incremental cost is modest; retrofitting later is not.
Shower Pan and Waterproofing Replacement
If you’ve got a tiled shower over a failed pan, you may already have subfloor rot spreading under the bathroom floor. We demo to the joists, replace damaged framing, and rebuild with modern waterproofing systems. Highland’s older slab-on-grade homes need special attention here: without a crawlspace, trapped moisture has nowhere to go, and a leaking pan quietly undermines the slab over the years.

Trusted Brands We Service in Highland
Our remodels lean on materials that hold up to Highland’s heat and water chemistry. We specify fiber-cement backer board and James Hardie exterior materials on ADU builds, and that same standard carries inside: cement board, not green drywall, behind every tile surface. We work with fixture and finish partners that carry stock locally, so a Kohler or Delta valve replacement doesn’t stall a Highland project for a week waiting on a backordered part. When a project pairs with an ADU, we can pull from our prefab partner network including Plant Prefab and Abodu to align bathroom finishes with the new unit’s spec package.
Common Bathroom Remodeling Problems We See in Highland Homes
- Galvanized supply lines corroded shut. Homes built before the 1970s in Highland’s original tracts often still have original galvanized steel, and by now the interior diameter can be narrowed to a pencil. A re-pipe in PEX becomes the only responsible option once we test flow.
- Failed shower pans hidden by cosmetic fixes. Reglazing over a leaking pan makes a bathroom look fine for a few years while water eats the subfloor. We see this constantly on flipped homes in the east-side subdivisions.
- Hard water damage to valves and cartridges. Highland’s mineral-heavy supply means pressure-balance valves and thermostatic cartridges fail early. We spec fixtures with serviceable internals and plan treatment upstream.
- Unpermitted prior work with undersized framing or wiring. A previous owner’s handyman shower addition often hides undersized joists or buried junction boxes. Opening a wall triggers code review, and we handle the correction rather than hiding it back up.
Pricing for Bathroom Remodeling in Highland, CA
A gut-and-replace hall bath in Highland runs $18,000 – $30,000 depending on tile choice, fixture grade, and whether we find galvanized pipe that needs replacing. A primary bath with a custom walk-in shower, double vanity, and water treatment rough-in lands between $28,000 and $65,000. Here’s the breakdown for a typical Highland hall bath:
- Demolition and disposal: $1,500 – $2,800
- Rough plumbing (including PEX re-pipe when needed): $3,500 – $6,500
- Waterproofing and tile installation: $4,000 – $8,000
- Fixtures, vanity, and finishes: $4,000 – $10,000
- Electrical and exhaust fan upgrades: $1,200 – $2,500
- Water softener loop or treatment rough-in (when specified): $900 – $2,200
What moves the number most in Highland is what’s behind the tile. A 1960s bath with galvanized pipe and a rotted subfloor is a different project than a 2005 bath with clean PEX and a solid pan. We write allowances into every contract for the known unknowns, and any change order is priced and approved in writing before a single fixture gets touched. Call (877) 658-7475 for a line-item estimate.

FAQs – Bathroom Remodeling in Highland
Yes, a permit triggers review of everything we expose, and older Highland homes often need wiring and plumbing brought to current code once walls open. We pull permits on every remodel, schedule inspection close-out, and never bury unpermitted work.
Highland’s mid-century tract homes were built when galvanized supply lines and aluminum branch wiring were standard, and most have never been fully replaced. We anticipate this on pre-1980 homes and write a contingency into the contract rather than surprising you later.
Absolutely. Highland’s mineral-heavy water accelerates scale in valves, cartridges, and supply lines, so we recommend planning a water softener loop during rough-in. If you don’t, expect fixture failure years earlier than rated.
We price the change order before doing corrective work. If we find a rotted subfloor, failed pan, or corroded pipe, you’ll see photos, a line-item price, and a written approval request. No surprises, no verbal estimates.
Yes. We’re ADU specialists first, and we often package a house bathroom remodel with a new detached unit, converting a Tuff Shed or completing a prefab build alongside your primary-bath upgrade. One contract, one schedule, no handoffs between separate crews.
