Fast, Reliable Bathroom Remodeling Across Upland
Bathroom remodeling in Upland typically costs between $14,000 and $38,000 depending on scope, and most projects take three to six weeks from demo to final walkthrough. That’s the honest range we quote homeowners across 91784, 91785, and 91786. Call (866) 251-7857 for a free estimate and we’ll scope your Upland project within days, not weeks.
We know Upland’s homes because we work here constantly. Ranch houses off 16th Street, bungalows near Memorial Park, foothill properties above Euclid Avenue. Every neighborhood has its own quirks, its own plumbing realities, its own set of surprises behind the walls. Rob Cafferty, who leads Foundry ADU Builders, has built his reputation on showing up prepared and quoting honestly. You’ll get that from your first call.
Why Foundry ADU Builders Is Upland’s Preferred Bathroom Remodeling Company
Our Bathroom Remodeling team has handled projects throughout Upland long enough to know what’s behind your tile before we open the wall. That matters in a city where the housing stock ranges from early-1900s citrus-era bungalows to 1970s ranches, each with different framing, different plumbing layouts, and different ways of failing.
We’re not a general contractor that happens to do bathrooms. Foundry is an ADU-first builder, which means we think about bathrooms as part of a larger system: water lines, drain stacks, ventilation, moisture. That systems perspective pays off when we remodel a bath inside an old Upland home or inside a garage conversion out back. One contractor, one accountable relationship, from framing to finishes.
Upland homeowners tell us the same thing: they want a bathroom that handles the heat, vents properly, and doesn’t leak. We deliver that with materials that stand up to Inland Empire conditions. We use James Hardie backer board, Schluter waterproofing systems, and properly sized exhaust fans matched to each bathroom’s cubic footage. That’s not an upgrade. It’s baseline.
Our Bathroom Remodeling Services in Upland
Full Bathroom Remodeling
We gut and rebuild full bathrooms in Upland homes, from compact hall baths in 1940s ranches near the foothills to larger master baths in newer builds south of Foothill Boulevard. A typical full remodel includes new shower or tub, vanity, toilet, flooring, lighting, and exhaust fan. We handle every trade in-house or through our direct subs, so you’re not coordinating three different crews.
What changes the price in Upland is often what’s behind the walls. Galvanized pipes in older homes near Euclid Avenue may need replacement. Cast iron drain stacks in 1920s houses can be corroded. We identify these during the estimate, not after demo starts.

Tile and Waterproofing
Tile work in Upland bathrooms has to survive real thermal cycling. Summer heat pushes surface temperatures past 100 degrees, then Santa Ana wind events drop humidity to single digits. That expansion and contraction is brutal on grout and thinset. We use Schluter membrane systems and modified thinset rated for our climate, then install tile with proper expansion joints where needed.
We also see a lot of failed tile jobs from previous remodels: cracked grout lines, hollow-sounding tiles, water staining at the shower pan. Fixing those right means tearing out to the studs. We quote the real fix, not a cosmetic patch.

Ventilation and Moisture Control
This is the service Upland homeowners underrate most. A bathroom fan that’s too small or vented into the attic creates mold that lives behind your tile for years before you notice. In Upland’s climate, with intense heat and Santa Ana-driven pressure changes, moisture lingers longer than it does in coastal cities. We size fans by CFM per square foot, duct them properly to the exterior, and seal every penetration.
On north-side Upland homes with citrus-era masonry walls, venting gets complicated. You can’t just punch a hole through a 12-inch estate wall. We route vents through the roof or gable ends, which costs more but preserves the wall and keeps the remodel legal.

ADA and Aging-in-Place Bathrooms
Many Upland homeowners are adding curbless showers, grab bars, and comfort-height toilets so parents can live in a converted garage or ADU on the property. We plan these bathrooms around actual mobility needs, not just code minimums. Wider door openings, non-slip tile, wall-mount sinks. These details matter when a family member moves in for decades, not just weekends.

Trusted Brands We Service in Upland
We’re not locked into one manufacturer. Foundry works across the full spectrum of construction methods, and the same applies to bathroom products and materials. We install James Hardie backer and cement board systems, Schluter waterproofing membranes, and fixtures from brands we know hold up under Inland Empire conditions. For ADU bathrooms attached to prefab units from Abodu, Plant Prefab, or Tuff Shed conversions, we match materials and finishes to the unit’s existing spec so the interior looks continuous, not bolted-on.
Common Bathroom Remodeling Problems We See in Upland Homes
- Cutting into historic masonry walls. On Upland’s north side, original citrus-era estate walls can’t be moved or pierced without triggering preservation issues. We see homeowners who hired out-of-town contractors get stuck mid-project because a wall was opened without checking the masonry first. We check wall composition before we ever quote.
- Undersized exhaust fans. The Inland Empire heat and Santa Ana wind events create moisture conditions that standard 50 CFM fans can’t handle. We regularly replace fans that were installed by previous contractors and sized for a coastal climate. The mold behind the tile is proof.
- Septic and well setbacks on larger lots. Upland’s deeper lots, especially moving toward the foothills, sometimes have septic systems. A bathroom addition or garage-conversion bath has to respect those setbacks. We verify septic locations and setbacks before we lock a floor plan.
- Galvanized supply lines and aging cast iron. Homes built from the 1920s through the 1950s in Upland’s core often still carry original plumbing. When we open a wall and find galvanized, we replace it. When the drain stack is cast iron and compromised, we schedule replacement in the same scope. Ignoring it means leaks inside a brand-new wall.

Upland’s permitting fees for bathroom remodels are modest compared to kitchen work, but north-side properties with historic walls may trigger additional review time.

FAQs – Bathroom Remodeling in Upland
Historic citrus-era masonry walls on Upland’s north side cannot be cut into or structurally altered for vents, windows, or plumbing penetrations without triggering preservation review. We work within those fixed lines by routing vents through the roof or gable ends, relocating plumbing inside the existing footprint, and designing window placement that leaves the estate wall untouched. This adds roughly $500 – $1,500 to a typical project but keeps you legal. Call (866) 251-7857 and we’ll check your wall composition first.
Most bathroom remodels within Upland city limits require city permits from the Upland Building Division, not San Bernardino County, when you’re moving plumbing, altering the footprint, or changing structural framing. If your property sits on county land or has an ADU that the county permitted, county review may also apply. We pull every permit for you and schedule inspections as part of the project. For an exact read on your lot, call (866) 251-7857.
Upland’s Inland Empire heat and Santa Ana wind cycles trap moisture in bathrooms longer than in coastal cities, which leads to mold behind tile and drywall failure if fans are undersized. We size exhaust fans to the room’s actual cubic footage and route ducting to the exterior, not into the attic. If you’re seeing mildew on ceilings or grout that stays damp, call (866) 251-7857 for an assessment.
Yes. We remodel bathrooms inside detached garage conversions, citrus-era outbuildings, and ADUs across Upland’s 91784, 91785, and 91786 zip codes. The main constraints are septic and well setbacks on deeper lots, plus the same masonry wall issues on north-side properties. We scope the plumbing route, vent path, and waterproofing before quoting. For a free estimate on your outbuilding, call (866) 251-7857.
We use James Hardie backer board and Schluter waterproofing membranes that hold up under repeated thermal cycling, and we size ventilation to handle 100-degree-plus summer conditions. For mountain-adjacent properties, we also consider fire-resistant materials on exterior-facing bathroom walls. These choices add life to your remodel in Upland’s climate. Call (866) 251-7857 and we’ll explain exactly what we’d spec on your house.
