Fast, Reliable Bathroom Remodeling Across Upland
High-end bathroom remodeling in Upland typically runs $38,000 – $75,000 for a full gut and rebuild, with custom vanity and architectural-glass work pushing toward $90,000 on larger master baths in 91784. The calendar is driven by long-lead items, not labor. Custom cabinetry, imported slab, and specialty glass run eight to fourteen weeks from order to delivery, which means the right sequence is everything. We plan Upland remodels around those lead times so your vanity is ordered only after the walls are open and the plumbing is confirmed. Call us at (855) 341-3461 to schedule a free estimate.
Why Sentinel ADU Builders Is Upland’s Preferred Bathroom Remodeling Company
We work across Upland’s three distinct housing eras, from mid-century ranches in 91786 to larger custom homes off Euclid Avenue in 91784. That span means we have seen the plumbing behind the walls in this city more times than most contractors see in a career. Noel Ibarra runs every Upland project personally, reviewing the rough-in before drywall and walking the finish list with the homeowner. The result is a written, fixed price on long-lead items before anything is ordered, so a change is a conversation, not a surprise invoice.
The Sentinel name is not decoration. It describes how we run the schedule. We stay on the job from permit to punch-list, which matters in Upland because city plan check on a hillside-adjacent bathroom with window changes can take two to three weeks longer than a flat-land remodel in Montclair or Claremont. We manage that front-loading so the inspection schedule does not stall the finish date.
Our Bathroom Remodeling Services in Upland
Most Upland homeowners come to us because someone has told them their bathroom cannot be done the way they want it, or because they have already been burned by a contractor who opened a wall and discovered plumbing that was never in the bid. Our Bathroom Remodeling team addresses that from day one with a sequenced order plan. Here are the sub-services that matter most on Upland’s high-end work.
Custom Millwork and Cabinetry
A custom white-oak or walnut vanity set into a 1960s Upland ranch is not a stock item you order from a catalog. We build and install vanities, linen towers, and medicine cabinetry to the exact width of the wall, accounting for the fact that many Upland homes have non-standard stud bays and wonky corners after sixty years of settling. If you want a furniture-style vanity with a stone top and integrated sconce millwork, that is a twelve-to-fourteen-week lead item. We measure, order, and lock the price before the order goes to the shop.
Architectural Glass and Specialty Finishes
Frameless glass shower enclosures, fluted-glass privacy panels, and full-height architectural mirrors are standard on higher-end Upland baths. These are not glass-shop commodity items; they are cut to the opening after the tile is set, and the hardware is spec’d for the weight of 3/8-inch or 1/2-inch glass. In Upland’s hillside homes, we also specify glazing that meets the fire-severity window requirements north of Foothill Boulevard, which changes the frame and glass spec compared to a flat-land swap.
Designer and Architect Coordination
Many Upland remodels start with a designer’s drawing and a material schedule from a showroom. We coordinate with that designer or architect directly: we review the plumbing rough-in against their elevations, flag any wall-depth or drain-location changes before the vanity order is placed, and manage the submittal process with Upland’s building department. That coordination prevents the most expensive mistake in this city, which is a $9,000 custom vanity ordered to a rough-in that does not exist.
Full-Scope Rough-In and Re-Pipe
Before any finish goes on the wall, the plumbing has to be right. In Upland’s pre-1980s housing stock, that often means replacing cast-iron drains and 1.5-inch galvanized supply lines. We handle that scope directly, with our own plumbing crew, not a sub we call twice a week. A 2-inch PVC drain and 3/4-inch PEX supply lines are the standard we run before any custom slab or cabinetry is set.

Trusted Brands We Service in Upland
Because Sentinel is brand-agnostic, we recommend the right product for your bathroom, not the one we are locked into. On Upland remodels we regularly work with fixtures and systems from Dvele and Mighty Buildings when the project includes an attached or adjacent ADU bath, and we spec James Hardie fiber-cement backer and exterior materials on any hillside wall that interfaces with the bathroom. We do not stock parts in the sense of keeping imported tile on a shelf, but we do maintain fast ordering relationships with the regional suppliers who serve Upland and the Inland Empire, which shortens the delay when a special-order valve or glass hinge shows up wrong.
Common Bathroom Remodeling Problems We See in Upland Homes
- Cast-iron drain failure in 1960s and 1970s ranches. The original cast-iron waste lines under slab and behind walls crack at the closet bend after 50 to 60 years. We find it on most gut remodels in 91786. The repair is a drain re-pipe, not a patch, and it has to happen before any finish goes in.
- Undersized 1.5-inch galvanized supply lines. Many Upland ranches were built with half-inch and 1.5-inch galvanized that has corroded from the inside, reducing flow pressure at the shower valve. A high-end shower with body sprays and a rain head will not perform on those lines. We re-pipe to 3/4-inch PEX during the rough-in.
- Heritage citrus tree setbacks. A surprising number of bathrooms in older Upland back up to a yard with a mature orange or lemon tree the owner wants kept. The city’s tree-protection and setback rules can force a window or vent relocation. We map that during the site plan phase, not after the tile is selected.
- Foothill fire-severity window and vent requirements. Bathrooms on the north side of Foothill Boulevard, especially in 91784 where lots climb toward the San Gabriels, fall into fire-severity zones that require tempered glass, specific frame ratings, and ember-resistant vents. A contractor who specs standard vinyl windows from a big-box supplier will fail final inspection.
Pricing for Bathroom Remodeling in Upland, CA
A hall bath in Upland generally runs $28,000 – $45,000 for a full gut, re-pipe, and rebuild with quality tile, custom cabinetry, and standard glass. A master bath in 91784 with architectural glass, custom white-oak vanities, and a freestanding tub typically lands between $55,000 and $85,000. If your ranch home’s cast-iron drain needs a re-pipe, add $3,500 – $7,000 depending on the length of the run and how much slab has to open. Custom cabinetry runs $9,000 – $18,000 on the vanity depending on wood species and size. Architectural-glass shower enclosures run $3,200 – $6,500 installed. Our price is fixed in writing before we order any long-lead item, so the number does not drift once the cabinet shop starts cutting. Call (855) 341-3461 for a free estimate.

FAQs – Bathroom Remodeling in Upland
Yes, in most 1960s and 1970s ranches in 91786, the original cast-iron drain under the bathroom is already cracked or severely corroded, and the supply lines are undersized galvanized. We open the wall and confirm the rough-in before we order any custom vanity or slab, because the drain location often shifts by two to four inches once the re-pipe is complete. That shift changes the cabinet depth or sink rough-in. Ordering the vanity first is how a $9,000 piece ends up in the wrong wall. Call (855) 341-3461 and we will map the plumbing before any order is placed.
Bathrooms north of Foothill Boulevard in 91784, where lots climb toward the San Gabriels, fall into high-fire-severity zones under Upland’s building code. Windows in those bathroom walls must meet specific frame and glazing standards, and vents must be ember-resistant. We spec those materials during the plan phase and submit them with the permit package, so final inspection does not stall over a window that a flat-land supplier said was fine. Call us at (855) 341-3461 for a free estimate that accounts for hillside requirements.
Custom cabinetry, imported slab, specialty plumbing fixtures, and architectural glass are the long-lead items. Custom vanities run eight to fourteen weeks from shop order to delivery. Imported tile and stone from European or specialty domestic suppliers runs six to ten weeks. Frameless glass is measured after tile, then cuts two to three weeks. We sequence the permit and rough-in work so those items are ordered at the right moment, and the price is fixed in writing before the order goes to the shop. Call (855) 341-3461 to schedule your free estimate.
Yes, with the right site plan. Upland’s tree-protection rules in 91786 mean a mature orange or lemon tree can force setbacks that shift an ADU bathroom footprint by a foot or more. We map the tree and its drip line before finalizing the layout, and we design the bathroom around the setback rather than asking the city for a removal. On several Upland jobs we have kept heritage citrus in place while completing the full bath. Call (855) 341-3461 and we will walk your yard with the tape.
We work directly with your designer or architect from the first site measure through final inspection. We review their elevations against the actual rough-in, flag any wall-depth or drain-location issues before the vanity order, and manage the plan check submittals with Upland’s building department. That keeps the designer’s intent intact while making sure the build actually works in a sixty-year-old wall. Call (855) 341-3461 to set up a walkthrough with your design team.
