Fast, Reliable Bathroom Remodeling Across Fontana
A full bathroom remodel in Fontana typically runs $9,000 to $28,000, and the single biggest factor in that spread is what the house gives you once the walls are open. Older Fontana homes, especially the 1950s and 60s tract houses built for Kaiser Steel families, hide framing surprises that newer subdivisions never do. We inspect before we quote, price before we demo, and put the number in writing before a single tile comes up. Call (936) 259-2607 to schedule a walkthrough.
We’re part of the Kingswell family of companies, operating to The Kingswell Way since 2004. That means a written price before work starts, a defined arrival window, a clean job site, and a written guarantee on every project. Our crew shows up in uniform, background-checked, and ready to explain exactly what your Fontana bathroom needs before we touch it.
Why Penhallow Remodeling Is Fontana’s Preferred Bathroom Remodeling Company
Fontana homeowners keep calling us back for one reason: we tell them the truth about what their house is going to cost before demo day, not after. Trevor Nash leads every project with a simple rule – say the price before the work, show up in the window we gave, and leave the place cleaner than we found it. That rule holds whether we’re converting a tub in a 1958 post-war tract home near Sierra Avenue or fitting a walk-in shower in a newer master plan off Summit Avenue.
Our Bathroom Remodeling team works across every Fontana neighborhood, from the older streets around the former Kaiser mill district to the 80s and 90s stucco builds north of the 210. Scheduling and dispatch are coordinated from our Inland Empire office, and crews serve Fontana locally. A live person answers the phone 24/7. No voicemail maze, no callback window. You call, a real human picks up, and we get you on the books.
Every project carries the 365-Day Done Right Promise in writing. If the work fails inside the guarantee period, we come back and fix it at no charge. Not a pro-rated deal, not a service fee. A free second visit if the repair fails, covered on paper before we start. That’s the Kingswell standard, and it applies to every tub-to-shower conversion, vanity install, and full bathroom remodel we do in Fontana.
Tub to Shower Conversion in Fontana
A tub to shower conversion in Fontana typically runs $3,500 to $10,000 depending on what the demo uncovers and whether the existing wet wall needs reframing or electrical upgrades. It’s one of the most common requests we get from homeowners in older Fontana homes where the tub has become a hazard – a high step-over for aging knees or a tired 1970s acrylic that never drains right. The job means removing the tub, reframing the footprint as a walk-in shower, waterproofing to current code, and then setting your new valve, tile, and glass.
Here’s the thing Fontana homeowners don’t expect: in a 1950s slab-on-grade tract home, the original wet wall often hides rust-through galvanized supply lines and cloth-wrapped wiring. We price for what’s behind the tile, not what we hope is there.
Waterproofing and the Open-Wall Surprise
Most of the 1950s and 60s slab-on-grade tract homes in Fontana’s older core were built with 2×4 walls on a 2×6 sole plate tucked behind single-wall stucco. When bathroom demo reaches the original wet wall, there is almost never a true stud cavity to fur out a new valve or GFCI outlet. The whole wall comes down to structure before a carton of Kohler can go in.
We budget for that before we start, not after we’re standing in your shower pan. That’s the difference between a clean conversion and a change order nobody explained.
Shower Base, Valve, and Finish Choices
You’ll pick the shower base, the valve trim, and the finished wall material. We install Kohler and Moen fixtures, and we write the valve trim allowance into the contract so a mid-project upgrade doesn’t blow the number. Cambria and Silestone surfaces carry their own warranties alongside ours, which gives you two layers of protection on the finished product.
One Day Bath Remodel in Fontana
A one day bath remodel in Fontana is a focused replacement – a tub or shower swap, a new surround, a vanity, or a fixture refresh – completed in a single working day, typically in the $5,000 to $12,000 range when we’re working inside an existing footprint. It’s the right call when your bathroom works but looks worn, and you don’t want to live through a two-week gut. The key is that the walls stay closed, so there’s no rough-in inspection trigger and no surprise wall framing.
For most Fontana homes built after about 1985, a one-day remodel is very doable. For older tract homes, we’ll tell you honestly whether your wall cavity can handle a same-day surround or whether you’re better off with a full open-wall conversion done right.
What We Can and Cannot Do in One Day
We can pull a dated tub surround, set a new acrylic or tile surround, hang a new vanity, swap the toilet, and replace the trim on your fixtures. We cannot re-route plumbing, replace a failing subfloor, or move a drain in one day – those jobs need open walls, and open walls need a permit and an inspection. We’ll tell you which job yours is before you commit.
The Written Price Still Applies
Even a one-day remodel gets a written price before we start, a defined arrival window, and the 365-Day Done Right Promise in writing. A fast job should never mean a loose number. You’ll know exactly what the day costs, what’s included, and who’s walking through your door.
Trusted Brands We Service in Fontana
We install product from manufacturers with real warranties behind them – Kohler and Moen for fixtures, KraftMaid and Wellborn for cabinetry, and Cambria, Silestone, and Caesarstone for countertops. These brands matter because the products behind our guarantee are as solid as the promise itself. When a Fontana homeowner wants a vanity with a Cambria top, we stock and source it locally so turnaround stays tight. Abodu and Cover are two brands we’ve worked with on accessory dwelling and panelized bath projects, and we’re familiar with the spec sheets before we walk through your door. If a brand carries its own warranty, we’ll explain how that layers with our 365-day coverage – both in writing, both on paper, both yours.
Common Bathroom Remodeling Problems We See in Fontana Homes
- Rust-through galvanized supply lines. In 1950s and 60s tract homes, the galvanized pipes behind the wet wall have often been corroding for 60 years. We’ve opened walls to find pinhole leaks feeding the subfloor for years before anyone noticed.
- Failed waterproofing from the original build or a 70s remodel. Single-wall stucco and original tile surrounds were never waterproofed to modern code. Water gets behind the tile, rots the sole plate, and invites termites.
- Undersized electrical panels. Older Fontana homes often have 60-amp or 100-amp panels. Once you open a wall and a permit triggers code review, the GFCI requirement can force a subpanel upgrade you didn’t budget for.
- Termite-damaged sole plates. The 2×6 sole plate under the wet wall is a favorite termite entry point in slab-on-grade homes. If the plate is compromised, the wall loses its anchor and the repair has to happen before anything else goes back in.

FAQs About Bathroom Remodeling in Fontana
In most cases: rust-through galvanized supply lines, cloth-wrapped wiring, and a subfloor that’s been getting fed by a pinhole leak for years. The original single-wall stucco framing usually means no true stud cavity to work with, so the wall comes down to structure before a new valve or GFCI can go in. We price for that reality before demo starts, and anything beyond the allowance gets a written change order you approve first. Call (936) 259-2607 and we’ll explain what your specific wall is hiding, based on the age and tract of your street.
Yes, any remodel that opens a wall, moves plumbing, or changes electrical wiring requires a city of Fontana building permit. The permit triggers a rough-in inspection while the wall is still open, which means the work has to be done right before we close it back up. It can also trigger a code review that flags an undersized electrical panel – and that’s a real cost, not a scare tactic. We pull the permit, schedule the inspection, and handle the paperwork. You’ll know the permit is part of the job, not something to dodge.
A tub-to-shower conversion in Fontana typically takes 2 to 4 working days once demo starts. A full remodel with flooring, vanity, and glass runs 2 to 4 weeks. Timelines move when the open wall reveals something nobody could have seen before – a rotted sole plate, a corroded drain, an electrical panel that won’t pass inspection. We build those contingencies into the schedule and price them into the contract before you sign. If a surprise appears, you get a written change order with a new number and a new schedule, and nothing restarts until you approve both.
A written change order is the piece of paper that keeps the number on day one from becoming a different number on day ten. It documents what changed, why it changed, and what the new price is – before the work is done. On older Fontana homes, that’s not a formality. It’s the difference between a contractor who eats the surprise and a contractor who hands it to you at the end and says “that’s construction.” With Penhallow, every change is written, priced, and approved in writing before we touch it. The number on your invoice matches the number you approved. That’s the whole point.
Sometimes, but only if the existing wall cavity and plumbing can support a same-day surround. In a 1950s Kaiser-era tract home, the answer is frequently no – the original wall framing doesn’t have a cavity we can fur out, and the galvanized supply lines need to be replaced. We’ll tell you honestly before you book. If a one-day remodel is possible, you get the same written price, written guarantee, and 365-Day Done Right Promise as a full gut. If it’s not, we’ll quote you the open-wall conversion with the real structural work included so there’s nothing hiding behind the tile.
Call Penhallow Remodeling for Your Fontana Bathroom Remodel
We were tearing a tub surround out of a 1958 slab-on-grade home off San Bernardino Avenue just outside the old Kaiser mill district, and underneath the tile was rust-through galvanized supply, cloth-wrapped wiring, and a subfloor that had been getting fed by a pinhole leak for years. Our tech stopped at demo, wrote up the framing, rough-in and panel work as a priced change order, and only then did the tub-to-shower conversion go back in. No surprises in the wall, no surprises on the draw schedule.
That’s the standard every Fontana project gets. Trevor Nash and the team at Penhallow Remodeling will inspect before we quote, price before we demo, and put the number in writing before a single tile comes up. Call (936) 259-2607 now to schedule your free estimate. A live person answers, day or night.
