Fast, Reliable Bathroom Remodeling Across Bloomington
A bathroom remodel in Bloomington typically runs $18,000 to $42,000 for a full gut-and-replace, with detached ADU bathrooms inside garage conversions ranging $14,000 to $28,000 depending on septic capacity and rough-in work. Most Bloomington projects take three to six weeks from demo to final inspection, and county plan review can add two to four weeks before we even break ground. If you’re planning a bathroom inside a detached ADU or garage conversion off the 92316 corridor, call us at (855) 676-6807 before you buy tile. The septic question comes first.
We’re Sunburst ADU Builders, led by Noel Carrasco, and we’ve done enough work across unincorporated San Bernardino County to know that Bloomington is not Fontana. The permitting path is different. The lots are bigger and older. And a bathroom remodel here can live or die on a septic leach field that nobody thought about when they drew up the Pinterest board. That’s the work we do every week, and we scope it before we quote it.
Why Sunburst ADU Builders Is Bloomington’s Preferred Bathroom Remodeling Company
Bloomington homeowners call us because we understand the county layer most contractors skip. A bathroom inside a detached ADU, a garage conversion, or even a back-house addition on an older agricultural-legacy parcel runs through Bloomington county jurisdiction, not a city counter. That means County of San Bernardino Land Use Services reviews the plans, and on septic-dependent lots, the bathroom scope can hinge on leach field capacity before a single fixture gets ordered. We plan for that on day one.
Our Bathroom Remodeling team has scoped and built bathrooms across the 92316 corridor, from parcels near Cedar Avenue to the older ranch-home streets south of Slover. Homeowners around Valley Boulevard and the unincorporated pockets near the 10 freeway tell us the same thing: they assumed the city would handle permits and a different contractor quoted them tile before anyone checked the septic. That’s not how we work.
Noel Carrasco built this company around a simple rule: scope the real constraints first, then quote honestly. That’s why we walk every Bloomington parcel, check what was actually permitted, size the bathroom to the septic or sewer reality, and give you a written line-item quote that doesn’t change once we open the walls.
Our Bathroom Remodeling Services in Bloomington
Detached Garage-to-ADU Bathroom Conversions
Bloomington has a lot of detached garages, and a fair number of them were never permitted as living space. We convert those garages into legal ADUs with full bathrooms, which means county plan review, proper wet-wall rough-in, and a bathroom layout sized to the septic system’s actual capacity. We handle all of it, from foundation and slab work to tile, shower, vanity, and final inspection.
Septic-Feasibility Scoping for ADU Bathrooms
This is the Bloomington-specific step that every other page skips. Before we quote a bathroom in a detached unit, we check what the county will require. If the parcel runs on septic, the bathroom may need to be sized to the leach field, or the septic may need an upgrade. We scope that first so your quote reflects reality, not a guess. Homeowners who skip this step find out the hard way when county review stops the permit.
County-Permitted Wet-Wall and Rough-In Work
We pull permits through County of San Bernardino Land Use Services and schedule inspections on the county’s timeline, not a municipal counter’s. That matters on every Bloomington ADU bathroom. Our crews trench drain lines, set venting, and run supply lines to code, then schedule the county inspection before any drywall goes up. Noel Carrasco’s team has done enough of these to know exactly what the county inspector will look at.
Interior Finish and Aging-in-Place Bathrooms
Much of Bloomington’s housing stock is mid-century single-story tract and ranch homes, which means 60-year-old bathrooms with failing cast-iron drains, water-damaged subfloor, and layouts that don’t work for homeowners who plan to stay. We rebuild them as curbless showers, wider door openings, and grab-bar-ready wet zones when you want them, and we tie the work into a full Bathroom Remodeling scope so the new room actually matches the rest of the house.

Trusted Brands We Service in Bloomington
We’re not tied to a single product line, and that matters for Bloomington homeowners comparing options. For ADU bathroom packages we work with Cover and Dvele when you want a factory-built unit with the bathroom already engineered in, and we’ve used Mighty Buildings panels on projects where a 3D-printed shell made sense for a tight lot or a fast timeline. For interior finishes we specify products we’d put in our own homes: solid-brass shower valves, name-brand tile, and moisture-rated exhaust fans that actually move air in a summer like Bloomington’s. We stock common parts locally so lead times don’t stall your remodel.
Common Bathroom Remodeling Problems We See in Bloomington Homes
- Septic capacity stops the bathroom before it starts. On older agricultural-legacy parcels, the leach field may not support another full bathroom. County review can halt the permit, so we size the bathroom to the septic or plan the upgrade first. This is the single biggest surprise for Bloomington ADU owners.
- Unpermitted additions complicate everything. Plenty of Bloomington homes have a converted garage or added room that was never permitted. When we remodel a bathroom inside that space, the county may require us to legalize the addition before the bathroom permit moves forward. We check the county records before we quote.
- Summer heat and dust find their way in. Bloomington sits in the hot, dry western San Bernardino Valley. A bathroom with a weak exhaust fan turns into a mold chamber by August, and Santa Ana wind events push fine dust through every unsealed opening. We spec sealed envelopes, screened vents, and real cooling capacity.
- Long material hauls and tight garage access. Big open lots sound easy until a concrete truck can’t reach the detached garage and the dumpster sits a hundred feet from the slab. We plan access routes before demo so you don’t eat hand-carry labor on a simple wet-wall replacement.
Pricing for Bathroom Remodeling in Bloomington, CA
A full bathroom remodel in a Bloomington primary home runs $18,000 to $42,000. That includes demo, rough-in, permits, tile, fixtures, and finish. A bathroom inside a detached garage-to-ADU conversion runs $14,000 to $28,000, with the spread driven mostly by septic capacity and whether we need to trench a new drain line from the main house. If the leach field needs an upgrade, add $8,000 to $20,000 depending on what the county requires. We quote Bloomington work as a written line-item estimate, not a ballpark. Call (855) 676-6807 and Noel Carrasco or one of our project leads will walk the job with you and put real numbers on paper.
We Also Serve Cities Near Bloomington
Our crews work throughout the west end of San Bernardino County. If you’re in Fontana, Rialto, Glen Avon, or Pedley, we handle bathroom remodels there too, and the scoping questions are different. Incorporated cities like Fontana and Rialto run on municipal sewer, which simplifies the permit path. The septic-layer planning we do for Bloomington parcels isn’t the same job across the city line, and we scope each one to its actual jurisdiction. Call (855) 676-6807 and we’ll tell you what applies to your address.

FAQs – Bathroom Remodeling in Bloomington
County approval. Bloomington is unincorporated San Bernardino County, so a bathroom inside a detached ADU or garage conversion is reviewed by County of San Bernardino Land Use Services in San Bernardino, not a city building department. We pull the permits, schedule the county inspections, and keep the project moving on the county’s timeline. For Abodu repair in Bloomington, we can also check compatibility with your existing setup. Call (855) 676-6807 to have us check your parcel before you plan the layout.
Yes, and it happens regularly in Bloomington. If the parcel runs on a septic system, county review can require proof that the leach field has capacity for another bathroom. When it doesn’t, the bathroom scope has to shrink or the septic gets upgraded before the permit proceeds. We scope this first, not after you’ve ordered tile. Call (855) 676-6807 and we’ll tell you what your parcel can actually support.
Because Bloomington summers are brutally hot and dry, and a bathroom with poor ventilation becomes a moisture trap that breeds mold inside a year. We specify high-capacity exhaust fans, sealed and screened openings, and real insulation in the wet wall so the bathroom stays dry and the cooling load stays manageable. It’s a small cost up front that prevents a big problem later.
We check the county records before we quote. If the bathroom sits inside an unpermitted addition or converted garage, the county may require us to legalize the structure as part of the bathroom permit. We’ll tell you what that involves and what it costs before you commit to the remodel. Sometimes it’s straightforward; sometimes it changes the whole scope. Either way, you’ll know the truth up front. Call (855) 676-6807 for a free scoping walk.
Bloomington is unincorporated county jurisdiction with many septic-dependent lots, while Fontana is an incorporated city on municipal sewer. In Fontana, a bathroom in an ADU connects to the sewer and the permit path is simpler. In Bloomington, the county reviews the parcel, the septic may cap the bathroom’s size, and the timeline runs on the county’s schedule. We scope both, but they’re not the same job. If you’re deciding between two properties, call (855) 676-6807 and we’ll help you compare the real costs.
