Fast, Reliable Bathroom Remodeling Across Loma Linda

Bathroom remodeling in Loma Linda typically runs $14,000 – $38,000 for a full gut-and-replace, while a bathroom tied to a garage conversion or rear-yard infill ADU lands between $22,000 and $55,000 depending on slab work, panel upgrades, and drain relocation. We’re Cottage ADU Builders, led by Neil Stratton, and we work throughout the 92350, 92354, and 92357 ZIP codes. The phone number is (866) 808-7312 when you want a straight answer about your project. We’ve spent enough time in Loma Linda’s 1950s – 1970s ranch neighborhoods to know what hides behind those original tile walls before we ever open one up.

Why Cottage ADU Builders Is Loma Linda’s Preferred Bathroom Remodeling Company

Most of the bathrooms we remodel in Loma Linda are not standalone remodels. They’re attached to something bigger: a garage being converted into a rental unit for a medical resident, a rear-yard infill for aging parents, or a primary bath in an older ranch that finally needs its 1960s cast iron and galvanized lines replaced. That changes how we quote and how we build. Neil Stratton built this company around the idea that a second unit shouldn’t mean a second contractor, and in Loma Linda that philosophy matters because the bathroom and the ADU are usually the same project, not two separate bids.

We know the plan-check rhythm at the city. Loma Linda’s planning department scrutinizes occupancy and parking because street parking near the university and medical center is already tight. What that means for your bathroom remodel is simple: if your project triggers an ADU designation, expect questions about how the unit will be used, how many people will sleep there, and where the cars will go. We’ve been through enough of these reviews in Loma Linda to prepare submittal packages that answer those questions before the plan checker asks them.

Our Bathroom Remodeling Services in Loma Linda

Garage Conversion Bathroom Rough-In and Drain Relocation

Loma Linda’s buildable footprint is hemmed in by the 215/10, the San Bernardino hills, and the university campus, so nearly every ADU here is a garage conversion or rear-yard infill. That means your new bathroom needs plumbing that was never there. We cut and trench garage slabs, run new drain lines, and patch with thickened concrete so the floor can actually hold a shower pan and toilet flange without cracking. In Loma Linda’s 1950s-1970s garages, slab depth varies wildly, sometimes 3 inches, sometimes 5, and we verify that before we quote, not after we open the floor.

Electrical Panel and Water Heater Capacity Upgrades for ADU Baths

An original 1960s panel in a Loma Linda ranch cannot carry a tankless water heater, a bath exhaust fan, and a heat lamp on top of the existing house load. We scope panel upgrades into the bid up front when we know the project is an ADU bath. If the city plan check will flag occupancy, it will also flag a panel that’s maxed out. We’d rather tell you in the estimate that you need a 200-amp service upgrade than surprise you with it after drywall is up.

Bath Ventilation and Cooling Sized for Inland Empire Heat

Loma Linda hits triple digits in the summer, and a bath fan that meets minimum Title 24 CFM feels like nothing in a converted garage at 3 p.m. in August. We size ventilation beyond the code minimum and spec exhaust routing that actually moves hot air out rather than recirculating it. For detached ADU baths, we also look at window placement and insulation details that Title 24 doesn’t care about but your comfort does. Heat is not an abstract concern here; it’s the thing that makes a garage-conversion bathroom unusable in July.

Full Bathroom Remodeling in Existing Homes

Not every Loma Linda bathroom is tied to an ADU. We also do full remodels in the primary homes: waterproofing, shower pan replacement, vanity installation, tile work, lighting, and fixture upgrades. What changes in Loma Linda is the age of the plumbing we find. Galvanized supply lines and cast-iron drain lines from the 1960s and 1970s are common, and we often recommend replacing accessible sections while the walls are open rather than closing everything back up around 60-year-old pipe.

Trusted Brands We Service in Loma Linda

We work with the brands you’ve already been researching. For Loma Linda projects, that often means Mighty Buildings and Boxabl for prefab ADU shells where the bathroom is a pre-designed wet wall rather than a custom rough-in. On the interior side, we bring our own tile, waterproofing, and fixture selections, but we’re comfortable working within the tolerances and rough-in locations specified by the factory. Your lot, your budget, the right system. If you’ve already talked to a prefab rep or downloaded floor plans, bring them to the estimate. We’ll tell you honestly whether that system’s bathroom layout works on a Loma Linda slab or whether it fights the existing drain locations. Tuff Shed shells can work for rear-yard units, but their standard framing often needs additional blocking and waterproofing before a full bath goes in. We know what that takes.

Common Bathroom Remodeling Problems We See in Loma Linda Homes

• Slab depth surprises in garage conversions. The flat, low-pitch 1950s-1970s garages around Loma Linda commonly have slabs too thin for a standard shower drain. We confirm depth before quoting and include any thickened slab patch work in the bid.
• Undersized bath fans in converted garages. Triple-digit summer heat and Santa Ana wind events punish a fan that only meets code minimums. We size for actual heat, not just square footage.
• Panels that cannot carry a tankless heater plus bath vent. Most original Loma Linda ranch homes have 100-amp or smaller panels. Adding an ADU bath often triggers a service upgrade, and we scope that in before work starts.
• Plan check scrutiny on occupancy and parking. Because Loma Linda is built around the university and medical center, city planners look closely at ADU occupancy and where residents will park. A bathroom that reads as a full living unit changes the review, so we prepare drawings that anticipate those questions.
