Fast, Reliable Bathroom Remodeling Across San Bernardino
Bathroom remodeling in San Bernardino usually costs between $18,000 and $45,000 depending on whether you’re doing a tub-to-shower conversion, a full gut, or legalizing an unpermitted space. Most projects on the city’s mid-century tract homes run two to five weeks once permits clear. What changes the price isn’t the tile you pick. It’s what’s hiding inside the walls. We’ve opened enough 1950s and 60s bathrooms across San Bernardino to know exactly what’s in there before we give you a number, and that’s what keeps our quotes honest.

Why Sunburst ADU Builders Is San Bernardino’s Preferred Bathroom Remodeling Company
We’re based just down the road in Highland, so San Bernardino isn’t a satellite market for us. It’s our backyard. The homes off Del Rosa Avenue, the older core near Baseline, the north-end subdivisions pushing toward the foothills: these are the houses our crews work on every week.
Noel Carrasco leads our team, and the approach is simple. We quote what the house actually needs, not what makes the number look small on paper. That means a permit-ready plan from day one, an electrician and plumber who already know San Bernardino’s inspection routine, and a written change-order process for anything we find after demo. San Bernardino homeowners have told us more than once that another contractor gave them a lower first number and then hit them with five add-ons mid-job. We’d rather be the contractor whose first number holds.
Being tied into our Bathroom Remodeling team also means we’re not a solo remodeler juggling three jobs in three cities. When your project starts, the crew is on your San Bernardino job until it’s done.
Our Bathroom Remodeling Services in San Bernardino
Full Bathroom Remodeling
Full gut remodels are our most common job in San Bernardino, especially on the 1940s-1970s tract stock where original finishes are long past saving. We handle everything from layout changes to moving the shower to adding a second sink. Because much of San Bernardino’s housing is single-story on generous lots, we can often reorganize a cramped bath into a more open footprint without touching the exterior walls. Every project includes a pre-demo scope review so you know what the permit will trigger before we swing the hammer.
Tub-to-Shower Conversions
Older San Bernardino homes almost always have a tub-shower combo in the hall bath, and most homeowners want a walk-in shower with a bench and grab-bar blocking instead. We do these conversions frequently on homes in the 92418 and 92424 zip codes, where the original cast-iron tubs sit framed in by 2×4 walls that predate any modern water resistance standard. That’s why we always include pan replacement and backer board in the quote, not as a surprise line item.
Permit and Inspection Support
We pull permits on every bathroom remodel in San Bernardino. We don’t offer a “no permit” discount, because opening walls on a pre-1980 home without one means you’re inheriting every code violation we find, and we can’t leave ungrounded cloth wiring in the wall and call it done. Our team handles the plan-check process, schedules inspections, and walks the inspector through the job while you’re at work. If the city flags something, we’re the ones who fix it.
Panel and Service Upgrade Coordination
Here’s the San Bernardino reality: open up a 1950s or 60s bathroom and you’re looking at 2-wire ungrounded branch circuits and a 60-amp panel that’s been maxed out for decades. The permit forces the upgrade. We coordinate the electrical panel and service work as part of the bathroom remodel instead of you having to find a separate electrician mid-project. It’s one contract, one schedule, one set of inspections. We also bring the plumber in for galvanized supply replacement when we know it’s coming, not after the wall is open.

Trusted Brands We Service in San Bernardino
We don’t stick you with one product line and call it a day. Depending on the project, we spec James Hardie backer board because San Bernardino bathrooms need materials that handle real moisture in a dry, hot climate where the house moves. For shower systems and waterproofing we use membranes and pans that carry manufacturer warranties, not the cheapest roll at the supply house. And because we work with manufacturers like Boxabl and Plant Prefab on our ADU side, the same material discipline carries over to any bathroom we build inside a new accessory dwelling unit in San Bernardino.
Common Bathroom Remodeling Problems We See in San Bernardino Homes
- Failed hot-mop shower pans under original tile. The 1950s and 60s pans crack, the tile looks fine, and water has been seeping into the subfloor for a decade. We find this constantly on homes near Del Rosa Avenue and north toward the 210. You can’t tile over it. The pan comes out, the framing gets inspected, and we rebuild from the subfloor up.
- Ungrounded cloth wiring that triggers a panel upgrade. San Bernardino’s mid-century stock runs on 2-wire branch circuits with no ground. Once the wall is open for a bathroom permit, the inspector requires grounding and GFCI protection. We budget for this before demo so it’s not a shock later.
- Unpermitted garage or stealth bath conversions in the older core. A lot of San Bernardino homeowners bought houses with a bathroom someone added without permits years ago. When you remodel it, the city wants it legalized, which means plan check on pre-1980 stock and possibly a service upgrade. We handle the legalization as part of the remodel.
- No ventilation, and a bath that turns into a mold factory by August. In a climate with regular 100°F+ summers, a bathroom without a properly sized exhaust fan traps moisture from every shower and feeds mold behind the drywall within one season. We spec ventilation for the actual cubic footage, not just whatever fan fits the old housing.
Pricing for Bathroom Remodeling in San Bernardino, CA
A tub-to-shower conversion in San Bernardino typically runs $12,000 to $20,000. A full hall bath gut with new fixtures, tile, vanity, lighting, and ventilation lands between $18,000 and $30,000. A primary bath with a larger footprint, custom tile, and a relocated drain line starts around $28,000 and can reach $45,000. Add $3,500 to $8,000 if we know from the start that the panel upgrade is required, which is common on the pre-1980 homes across 92418 and 92424. Our quotes are line-itemed and we write allowances for unknowns like framing rot or failed plumbing, so the conversation about cost happens before we open the wall, not after.

FAQs – Bathroom Remodeling in San Bernardino
Because contractors who quote San Bernardino’s pre-1980 homes without opening the wall are guessing. A quote that “moves” usually means the contractor found galvanized supply lines, ungrounded cloth wiring, or rotted framing that they failed to include. Our process is inspection-first: we look at the house, we know the stock, and we write allowances for the likely findings into the contract before we start. When we do find something beyond scope, you get a signed change order with a price before we touch it. Call (855) 676-6807 and we’ll show you how an honest quote is built.
Not every bathroom permit does, but most of the 1940s-1970s tract homes in San Bernardino run on 60-amp panels with 2-wire ungrounded branch circuits. Once the wall is open, the inspector will require GFCI and grounded circuits in the bathroom, which usually means either a subpanel or a full service upgrade. We coordinate the electrical side as part of the remodel so it’s one permit, one schedule, and no surprise electrician bill after demolition.
Yes, and it’s a big part of what we do in San Bernardino’s older core. The city processes a high volume of ADU and remodel permits, and plan check on pre-1980 lots has specific requirements. We pull the proper permits, bring the unpermitted bath up to current code, and then remodel it to the finish you actually want. It adds time to the schedule, but it protects your property value and resale. Estimates for legalization work are free; call (855) 676-6807.
We use bonded membrane systems on every shower pan and James Hardie backer on walls, which is the minimum we’d accept on a job in this climate. For ventilation, we calculate fan CFM off the room’s actual cubic volume, and in San Bernardino’s hot Inland Empire summers, that means a properly sized exhaust with a timer is standard, not an upsell. A bath with no real fan grows mold within one season here. We won’t build that for you.
We write allowances into the contract for the specific problems this housing stock actually produces: failed hot-mop pans, galvanized supply stubs, and rot at the bottom plates of exterior-facing bath walls. The allowance tells you the maximum additional cost if we find it. If we don’t find it, you don’t pay it. If we do find it, you approve a signed change order with an exact number before we do the work. No open-ended plus-10% surprises after the walls come down.
