Fast, Reliable Bathroom Remodeling Across Mentone
Bathroom remodeling in Mentone means working with older homes where surprises live behind the walls: cloth-wrapped wiring, failed waterproofing, and drain lines tied into aging septic systems. We scope those problems before we swing a hammer, not after. The result is a quote that holds and a timeline you can actually plan around. If you’re weighing a hall bath refresh or a full primary suite overhaul in 92359, call (877) 801-4497 for a free estimate from a team that knows this corner of San Bernardino County.
Fullerton ADU Builders brings a specialist’s discipline to every Bathroom Remodeling project we take on in Mentone. We’re not a general contractor dabbling in tile work between roofing jobs. We open walls, find what’s actually there, and write change orders you approve in writing before we touch anything. That’s how you avoid the mid-tile stall that turns a three-week project into three months.
Why Fullerton ADU Builders Is Mentone’s Preferred Bathroom Remodeling Company
Mentone homeowners call us because we understand what lives inside the walls of mid-century ranch houses and the older crafton-area properties that dominate 92359. These homes were built in an era when galvanized drain lines, ungrounded circuits, and mortar-bed shower pans were standard. Remodeling them properly takes a contractor who has seen those exact conditions dozens of times, not a crew that only knows tract-home framing.
Led by Glen Pacheco, our team treats every bathroom remodel in Mentone as a discovery project with a disciplined process: inspect first, document what we find, price it in writing, and get your signature before the framer returns. That is why Mentone customers refer us to neighbors on Greenspot Road, along Crafton Avenue, and up in the foothill parcels near the bluffs. We do not guess. We open, we assess, we quote, we build.
We are also one of the few contractors serving Mentone that can bundle a bathroom remodel with an ADU build on the same property. If you have a large rural parcel and you’re already planning a detached unit, we can sequence the plumbing rough-in so both projects share one permit cycle and one contractor relationship. That is a real efficiency for Mentone lots where septic capacity and well output already complicate any new plumbing.
Our Bathroom Remodeling Services in Mentone
Full Bathroom Remodels
A full bathroom remodel in Mentone typically runs $18,000 to $38,000 depending on whether we are moving plumbing, replacing a tub with a walk-in shower, or bringing an original 1960s bath up to current code. On older ranch homes, this almost always includes rewiring, new drain runs, and sistering floor joists under the wet area. We write those allowances into the contract up front so the quote you approve is the project you get.

Shower and Tub Replacement
Replacing a failing shower pan or a cast-iron tub in Mentone runs $7,000 to $14,000 on average. On hill-adjacent lots where settlement has shifted the framing, we often find dry rot behind the tile that requires sistering before backer board goes in. We scope the drain and vent layout before demo so we are not cutting into a slab or a crawlspace blind. That pre-demo scoping is what keeps a simple swap from becoming a septic-system headache.

Walk-In Tub and Accessibility Conversions
Accessibility conversions in Mentone typically run $9,000 to $19,000. These projects usually involve widening door openings, reinforcing blocking for grab bars, and bringing the electrical up to a dedicated GFCI circuit. For homeowners planning to age in place on a large lot, we can also tie the conversion into a broader ADU plan so the primary bath and the future unit share water-heating or drain strategy.
Bathroom Flooring and Waterproofing
Flooring and waterproofing work in a Mentone bathroom runs $4,000 to $9,000. The original mortar-bed tile in many mid-century builds looks fine until the walls come open and the pan is gone, then the water damage underneath tells the real story. We install modern waterproofing systems designed for the East Valley’s heat, which means materials that can handle decades of intense summer temperatures without cracking or wicking.

Trusted Brands We Service in Mentone
On Mentone remodels, we specify James Hardie fiber cement for any siding-adjacent exterior work because it withstands the dry heat and wildfire ember exposure common to the 92359 foothills. For shower systems and waterproofing, we work with the brands that hold up under the valley’s temperature swings and hard water, and we keep the necessary parts on hand locally so we are not waiting on a supply-house shipment mid-project. When the scope includes an ADU alongside your bathroom, we also draw on our working knowledge of prefab manufacturers like Abodu, Cover, and Dvele to match the right unit to your lot. Whether you are remodeling the primary bath or adding a second dwelling, we stock and specify for Mentone’s conditions, not a generic California coastal climate.
Common Bathroom Remodeling Problems We See in Mentone Homes
- Cloth-wrapped or ungrounded wiring. Original mid-century ranch homes in Mentone frequently still carry two-wire circuits without a ground. The moment we open a wall for a new vanity light or exhaust fan, code requires us to address it. We budget for a dedicated GFCI circuit on every remodel where this is a possibility, which is most homes built before 1970.
- Failed waterproofing behind mortar-bed tile. Mentone’s mid-century builders set tile over a thick mortar bed with no modern waterproofing membrane. The tile looks fine for decades until the pan cracks and the framing behind it has been soaking for years. We always plan for pan replacement and wall re-waterproofing on original baths.
- Undersized or damaged framing around tubs and showers. Hill-adjacent parcels in the crafton area settle over time, and years of slow leaks from failing pans rot the floor joists under the wet area. Sistering those joists before backer board goes in is required to pass inspection and to keep the new tile from cracking within a year.
- Septic-driven drain constraints. On large rural Mentone parcels still on septic, the original drain and vent layout was sized for a different era of fixtures. Adding a second sink or a heavier-flow shower can overload a drain line that was marginal to begin with. We scope the drain/vent layout before demo so we know exactly what has to move and what can stay.
Pricing for Bathroom Remodeling in Mentone, CA
Here is what we are seeing in the Mentone market right now. A mid-range hall bath remodel on an older ranch home runs $16,000 to $26,000. A primary bath with a walk-in shower, new vanity, tile floor, and the code upgrades those 1950s and 1960s homes almost always trigger runs $24,000 to $42,000. Accessibility-focused conversions and tub-to-shower swaps land in the $9,000 to $19,000 range.
What moves the number in Mentone is usually not the tile. It is what we find once the walls are open: a panel upgrade, a rotted joist, a drain line that has to be rerouted for septic compliance. We include allowances for these known unknowns in every contract and every change order is priced, presented, and signed before work begins. You will never get a surprise bill for work you did not approve in writing. Call (877) 801-4497 for a free estimate on your Mentone bathroom remodel.

FAQs – Bathroom Remodeling in Mentone
You will most likely find one of three things: cloth-wrapped or ungrounded wiring, failed waterproofing behind original mortar-bed tile, or framing damage under the wet area from years of slow leaks. On mid-century Mentone builds, it is often all three in the same room. We plan for each one with written allowances in the contract so the discovery does not stall the project or balloon the price without your approval.
Yes. Mentone sits in San Bernardino County’s unincorporated sphere, so permits route through County Land Use Services rather than a city building department. When we open walls and alter plumbing or electrical, the County requires us to bring the affected systems up to current code. That frequently means a dedicated GFCI circuit, a modern drain and vent configuration, and in some cases a panel upgrade. We build those requirements into the estimate before the permit is filed. Call (877) 801-4497 and we will walk you through what applies to your specific home.
We scope the drain and vent layout before demo, not after. On large rural parcels in 92359, the original plumbing tie-ins vary widely, and adding a higher-flow shower or a second sink can overload a marginal drain line. We run a pre-demo camera inspection where needed, confirm the septic line capacity, and design the new plumbing around what the system can actually handle. Private-well homes also get a pressure and flow check before we commit to any fixture spec. Call (877) 801-4497 for a site walk and we will tell you exactly what your parcel needs.
The biggest reason a quote moves is what the walls reveal once they are open. On a mid-century ranch in the Crafton-area foothills, our crew opened a hall bath to find cloth-wrapped wiring and a drum trap buried under a cracked mortar bed. We wrote a change order for a new drain/vent run and a dedicated GFCI circuit, got it signed before the framer returned, and the homeowner avoided a mid-tile stall. That is the discipline we bring to every Mentone project: find the condition before the framing starts, price it in writing, get your signature, then build. The alternative is a stalled project and an angry homeowner.
Yes, in two ways. First, ventilation matters more in the East Valley’s heat: we specify exhaust fans with higher CFM ratings and humidity-sensing controls so a remodeled bathroom does not turn into a mold chamber by August. Second, when a bathroom remodel touches an exterior wall, we use materials rated for wildfire ember exposure, including James Hardie fiber cement where siding work is involved. Defensible-space thinking applies indoors too: the more we can keep moisture and heat from degrading the framing, the longer your investment holds up.
