Fast, Reliable Bathroom Remodeling Across Fontana
Most bathroom remodels in Fontana run between $9,000 and $28,000 depending on scope, materials, and what we find when the walls come open. We’re Mason Remodeling, and we’ve been handling full bathroom remodels, tub-to-shower conversions, and walk-in shower installations across Fontana’s tract-home neighborhoods long enough to know exactly where the surprises hide. A slab-on-grade foundation changes how we route drains. A 1990s builder-grade tub often sits on a rotted subfloor nobody knew about. That’s why we put a written price in front of you before any work starts, not after we’ve already torn into your wall. Call (803) 680-2547 to schedule a free estimate and get a real number, not a guess.
Why Mason Remodeling Is Fontana’s Preferred Bathroom Remodeling Company

We earned our reputation in Fontana by doing the unglamorous things right: pulling permits, scheduling inspections, and showing up with a crew you already know by name and photo. Every technician who steps onto your property is background-checked and identity-verified under The Threshold Standard, a named process we don’t waive for any job, in any neighborhood. You get the technician’s name and photo before the visit, and they arrive in a clean uniform with a photo ID badge at your door. That matters when you’re home alone during a two-week remodel, or when your kids are doing homework in the next room while strangers work in the hall bath.
We’ve remodeled bathrooms near Sierra Avenue, in neighborhoods off Beech Avenue north of the 210, and throughout the newer tracts south of Summit Avenue. Fontana homeowners hire us because our pricing stays fixed once we hand you the written scope of work. No verbal estimate that grows into a final bill you never agreed to. Isaac Pruett leads our crew, and he’s the one who walks your project line by line before you sign anything. You’ll know what the permit fee costs, what the inspection schedule looks like, and what happens if we find damage behind the tile. That’s how a builder earns trust in Fontana, one bathroom at a time.

Bathroom Remodeling Companies in Fontana
Bathroom Remodeling Companies in Fontana range from solo operators working out of a pickup to full-service firms like ours. What separates them is what happens after the quote: who pulls the permit, who shows up on day one, and whether the price on paper matches the invoice at the end. Our Bathroom Remodeling team handles the full scope, from demolition and rough-in plumbing to tile, glass, fixtures, and final inspection sign-off. A complete bathroom remodel in Fontana runs $9,000 to $28,000 depending on footprint, materials, and what’s hiding under the original tub.
Full Remodel Scope and Sequence
A full bathroom remodel in Fontana starts with demo, then we address the rough-in: drain lines, supply lines, and any slab work the new layout requires. From there we waterproof, set tile, install the vanity and fixtures, and close out with the final inspection. In most 1980s and 1990s tract homes here, the original tub was installed before the walls were closed, which means getting it out cleanly is where the real work happens.
When a Full Remodel Makes Sense
You’re past cosmetic updates when the shower pan is failing, the drain layout won’t support a walk-in, or the original polybutylene supply lines need replacing. Fontana homeowners with single-bath houses often schedule a full remodel around a second bathroom being available, or plan for a two-week window when family can shower elsewhere.
Bathroom Renovation in Fontana

Bathroom Renovation in Fontana usually means keeping the existing footprint but replacing everything inside it: fixtures, tile, vanity, lighting, and often the subfloor. A renovation in Fontana runs $9,000 to $28,000 for a standard hall or primary bath, with the final number driven by what we find once the original tile comes up. In the slab-on-grade tracts that dominate Fontana, a renovation often turns into a partial rough-in replacement because the 30-year-old pan liner under the original tub has been leaking into the slab for years.
Slab and Subfloor Restoration
Before any new tile goes down, we assess the subfloor from above. Fontana has zero basement stock, so when a 1980s tract bath has rot, it’s in the plywood or the mortar bed directly over concrete. We cut out the damaged section, treat the area, and rebuild to the new shower base or tub specification before waterproofing begins.
Fixture and Material Upgrades
Most Fontana renovations start with a Kohler or Moen fixture package and a Cambria, Silestone, or Caesarstone vanity top. We spec these materials at the start so the allowance actually matches what you pick, not some builder-grade placeholder that balloons five figures later. That’s the most common way Fontana homeowners get burned on a renovation, and we won’t let it happen to you.
Trusted Brands We Service in Fontana
We install and service specification-grade product lines that are actually available to Fontana homeowners through our supplier network: Kohler and Moen fixtures, Cambria and Silestone surfaces, KraftMaid and Wellborn cabinetry. When a shower valve fails or a vanity top arrives with a chip, we can source the replacement locally and keep your Fontana project moving instead of stalling for a week. We also work with and around newer prefabricated and panelized building systems from manufacturers like Dvele and Mighty Buildings when a Fontana homeowner is planning a whole-home addition alongside a bathroom remodel and wants a coordinated material package. You get vetted, professional-grade materials in one scope of work, priced in writing before we order anything.

AfterCommon Bathroom Remodeling Problems We See in Fontana Homes
- Failed pan liners under original tubs. In 1980s and 1990s tract homes across north and central Fontana, the original shower pan often started failing ten years ago. The water goes straight into the slab, and nobody sees it until demo day.
- Polybutylene supply lines from the pre-2000 builds. That gray plastic piping was common in Fontana tract construction and it gets brittle with age. If we’re opening the wall anyway, replacing it at rough-in is the right call, and it’s cheaper than doing it later.
- Permit-skipping contractors leaving unflagged work behind. In Fontana, any change to the rough-in or drain requires a permit and inspection sign-off before the walls close. Unflagged work gets caught at resale or when a neighbor’s permit triggers a review.
- Unrealistic allowances set at signing. A Fontana homeowner picks Cambria and Kohler, then finds out the original scope only allowed for builder-grade tile and a box-store vanity. The difference comes as a change order worth thousands, not a pleasant surprise.

FAQs About Bathroom Remodeling in Fontana
Yes, if the scope touches rough-in plumbing, drain lines, or any structural change to the bathroom, the City of Fontana requires a permit and a rough-in inspection sign-off before the walls close. Swapping a faucet or painting doesn’t trigger one, but moving a drain or converting a tub to a shower does. We handle the permit application, schedule the inspection, and don’t close a single wall until the inspector signs off. Call (803) 680-2547 if you’re not sure whether your project needs one.
A full bathroom remodel in Fontana takes roughly two to three weeks from demo to final inspection, assuming no major slab surprises. Smaller scopes like a tub-to-shower conversion can finish in seven to ten days. The schedule depends on inspection timing with the city and how quickly you finalize fixture and tile selections. We build the calendar into your written scope so you know which days we’re there and which days we wait on the inspector.
A bathroom remodel in Fontana runs $9,000 to $28,000, with smaller baths falling between $5,000 and $12,000. The price moves on three things: what we find under the original tub, whether we replace aging supply lines, and the grade of tile, vanity, and fixtures you choose. Slab work is the biggest unknown in Fontana’s tract homes because damage isn’t visible until demo day. Our written price includes a realistic allowance so you’re comparing real scopes, not one lowball number designed to win the job.
A change order is a written addendum to the original scope that documents a price change before the work happens. Fontana remodels get them most often when a contractor lowballs the initial bid and then discovers slab damage or fails to include permit fees. We write change orders only for conditions we can’t see before demo, like a failed pan liner or rotted subfloor under a 1990s tub. You approve every change in writing before any additional work starts. Call us at (803) 680-2547 for a written quote that accounts for Fontana’s housing realities upfront.
Yes, we convert tubs to walk-in showers in Fontana all the time, including the oversized garden tubs common in 1980s and 1990s tract homes. A conversion runs $3,500 to $10,000 depending on the shower base, wall surround, glass, and whether we move the drain location. Most Fontana conversions also need a new pan liner and waterproofing system since the original tub wasn’t designed to be a shower. We handle the permit and inspection as part of the scope, never as an afterthought.
