We’ve worked the 1980s-1990s stucco tracts off Sierra Avenue, the newer infill near Summit Avenue, and the renovation-heavy neighborhoods around the Auto Club Speedway footprint. Fontana’s housing stock has specific failure modes that out-of-market contractors miss. The builder-grade plastic exhaust vent terminations and undersized fasteners on those original tract baths crack under Cajon Pass wind gusts topping 60 mph. Driven rain and dust get into the wall cavity behind the shower. We’ve opened enough walls in north Fontana to know the pattern. That’s why our Bathroom Remodeling team specifies wind-rated, backdraft-damper terminations with hot-dip-galvanized or stainless hardware on every exterior-venting bath remodel here.

Why Rowan Construction Group Rancho Cucamonga Is Fontana’s Preferred Bathroom Remodeling Company

Rowan Construction Group has delivered 4,000-plus projects since 2007, every one with a written price before work started and a documented photo record when the crew left. Under The Haven Standard, Clause 1 requires that written price; no change proceeds without a signed change order. That discipline is why our projects finish within a few percent of the agreed number.

Fontana customers get the same documentation: flat written quote, written scope, written warranty, and a 365-Day Done Right Promise printed on every contract. If it’s not done right, we make it right. Not a handshake. Terms you can read.

Our crews are background-checked and uniformed. A live person answers calls 24/7. Every visit produces a documented photo record included as standard, not an upgrade. And we offer a Free Second Opinion on any written estimate - bring a competitor’s quote and we’ll review it line by line at no charge.

We know Fontana’s conditions because we work here regularly. The expansive clay soils causing slab heave, the 105-110°F summers that stress sealants and adhesives, the wind-driven rain that finds every gap in a plastic vent hood. That local knowledge changes what we specify and what your bathroom costs to maintain.

Our Bathroom Remodeling Services in Fontana

Full Bathroom Remodeling

A full bathroom remodel in Fontana runs $9,000-$28,000 depending on footprint, fixture grade, and what we find when we open the walls. In the 1988-1995 tracts near Citrus Avenue, we regularly discover soft framing around failed exhaust vents and subfloor deviation from slab heave. We quote for those conditions upfront when we can see them, and we document everything we find with photos so there’s evidence, not argument. Our flat price includes permits pulled and inspections passed.

Walk-In Showers & Shower Remodeling

Walk-in shower installation in Fontana costs $4,500-$12,000. We emphasize this service here because the original fiberglass tub-shower combos in Fontana’s 1980s-1990s tracts are reaching end of life, and the slab-on-grade construction makes tub removal and shower re-framing a specific skill. We specify waterproofing membranes rated for the thermal cycling that Fontana’s 40-degree winter lows to 110-degree summer highs produce. Frameless glass shower enclosures are available with marine-grade hardware and sealed bottom tracks that won’t collect wind-blown dust.

Tub-to-Shower Conversion

Tub-to-shower conversion in Fontana runs $3,500-$10,000. This is one of our most requested services in the older tracts off Foothill Boulevard and Merrill Avenue, where the original tubs are shallow, narrow, and surrounded by failing tile on greenboard (not cement board). We remove the tub, re-frame for a curbless or low-threshold walk-in shower, install proper cement-board substrate with liquid-applied membrane, and re-terminate the exhaust vent with a metal hood and damper rated for Cajon Pass wind loads. The price includes disposal, rough plumbing, and inspection-ready documentation.

Vanities, Tile & Fixtures

Bathroom vanity installation in Fontana costs $800-$3,000 for replacement; more if we’re relocating plumbing or reworking electrical for lighting. We source KraftMaid and Wellborn cabinets, Cambria and Caesarstone countertops, and Kohler and Toto fixtures across our fifty-plus vetted brand relationships. That sourcing depth means the written quote contains honest numbers rather than inflated allowances. For tile, we specify porcelain over ceramic in Fontana’s hard-water conditions, with epoxy grout in shower enclosures to resist the mineral buildup that etches standard grout lines within a few years.

Trusted Brands We Service in Fontana

We maintain relationships with fifty-plus vetted material brands, which lets us quote real numbers instead of placeholder allowances. For Fontana bathroom remodels, we regularly specify Kohler and Toto fixtures for their ceramic disc valves that resist hard-water mineralization, KraftMaid and Wellborn vanities with plywood-box construction (not particleboard) for stability through slab-heave cycles, and Cambria or Caesarstone countertops that won’t etch in the alkaline water common to Inland Empire municipal supplies. We stock common hardware and fastener sizes locally, so wind-rated vent terminations and stainless or hot-dip-galvanized brackets don’t add weeks to your schedule. When we quote a frameless glass shower enclosure, the hardware is marine-grade 316 stainless, not the 304 that shows rust bleed within two seasons of Fontana’s wind-and-heat cycling.

Common Bathroom Remodeling Problems We See in Fontana Homes

• Cracked plastic exhaust vent hoods letting wind-driven rain into wall cavities. The original builder-grade terminations on 1980s-1990s Fontana tracts crack at the hinge or blow off entirely in 60 mph Cajon Pass events. We find rotted 2×4 framing behind the shower, sometimes extending into the exterior wall sheathing. Our fix: metal hood with backdraft damper, sealed to stucco with polyurethane sealant, fastened with stainless screws.
• Undersized or ungalvanized fasteners corroding in the wall. Standard zinc-plated screws and staples on original construction rust through in Fontana’s heat-cycling, hard-water environment. We replace with hot-dip-galvanized or stainless fasteners on every re-termination and framing repair.
• Slab heave causing subfloor deviation and cracked tile. Expansive clay soils across the Inland Empire floor lift and drop slab foundations seasonally. In Fontana’s 1980s-1990s tracts, we’ve measured 3/4-inch deviation across a 5-foot bathroom run. We laser-level every subfloor before tile or LVP installation, and we quote self-leveling underlayment when the deviation exceeds 1/4 inch in 10 feet.
• Change orders from hidden water damage discovered mid-demo. Contractors who skip a documented scope and detailed allowances hit Fontana homeowners with surprises. Our written quote includes exploratory provisions with price caps, and no work proceeds on a change until the change order is signed. That’s Haven Standard discipline.
