Fast, Reliable Bathroom Remodeling Across San Bernardino
A full bathroom remodel in San Bernardino typically runs $18,000 – $38,000 for a hall bath and $32,000 – $65,000 for a primary bath, depending on what’s behind your walls. Homes built between 1950 and 1975 tend to land at the higher end once we open things up, because galvanized plumbing and undersized framing are common. Call (877) 265-9846 to schedule a free San Bernardino Dvele service in-home estimate. We work throughout San Bernardino, from Del Rosa to North Park to the areas around Cal State, and we’ve been inside enough of these tract homes to know exactly what to expect when the tile comes off.
Why Colonial ADU Builders Is San Bernardino’s Preferred Bathroom Remodeling Company
We cut our teeth on San Bernardino tract homes, and that matters. A 1962 stucco rambler near Del Rosa Avenue hides different problems than a 2005 build up by Cal State. We know which neighborhoods tend to have galvanized supply lines, which ones have early copper with pinhole leaks, and which floorplans make a primary bath addition harder than it looks.
Our team is led by Noel Carrasco, who has spent years remodeling kitchens and baths in San Bernardino and across the Inland Empire. Noel’s approach is simple: inspect before we quote, write allowances into the contract for what we can’t see, and never touch a change order without your written sign-off. That discipline is why our San Bernardino customers keep referring us to neighbors in Del Rosa, North Park, and the Westside.
Every bathroom remodel in San Bernardino gets a dedicated project lead who coordinates the plumber, electrician, and tile crew. We pull permits with the City of San Bernardino ourselves, schedule inspections, and handle the paperwork. You call one number. You get one contract. No chasing subs.
Our Bathroom Remodeling Services in San Bernardino
Full Bathroom Gut & Rebuild
We strip the room to the studs and rebuild it so it passes current San Bernardino code. That means new supply lines, new drains, new waterproofing, new subfloor if the old one has been wicking moisture for 40 years. We finish with tile or solid-surface surrounds, updated vanities, and proper ventilation. For older San Bernardino homes with original 2×4 framing, we sister or replace studs as needed before the inspector ever shows up.
Tub-to-Shower & Shower-to-Shower Conversions
This is the most common request we get in San Bernardino. Homeowners want the tub gone and a curbless, low-threshold shower in its place. In 1950s – 70s tract homes, the original tub was often set over a mortar bed that trapped moisture for decades. We remove it entirely, inspect the subfloor, and rebuild with a sloped, waterproofed pan. In some San Bernardino homes, this conversion is the difference between staying in the house and moving.
Walk-In & Low-Threshold Shower Builds
For older San Bernardino homeowners staying in their 1950s – 70s homes, a walk-in shower with a bench and grab-rail blocking is a practical, life-changing update. We can do a true curbless entry where the floor framing allows it; where it doesn’t, we use an ultra-low threshold. This is one place where hiring a local team matters, because we know which San Bernardino floorplans give us room to slope the floor without turning the project into a structural job.
Primary Bath Additions & Expansions
Some San Bernardino homes, especially the 3-bedroom tract homes, have a cramped hall bath and no primary suite. We can convert a bedroom closet into a compact en-suite or add a modest primary bath off the back of the house. On the 6,000 – 8,000 sq ft lots common in San Bernardino, there’s often room to bump out. We handle the structural, the plumbing, and the finish work under one contract, which keeps the project moving.
Trusted Brands We Service in San Bernardino
We install and service bathroom fixtures and finishes from the brands homeowners actually ask for: Delta, Kohler, Moen, and American Standard faucets and valves, along with Schluter waterproofing systems and James Hardie backer board where moisture resistance matters. We keep common trim kits, valves, and repair parts in our Apple Valley shop and can get San Bernardino jobs back on track fast when a manufacturer delivers a wrong or damaged piece. Our relationship with these manufacturers means warranty claims get processed without you having to chase down a distributor.
Common Bathroom Remodeling Problems We See in San Bernardino Homes
Homes in San Bernardino share a profile, and that means we see the same problems over and over. Here’s what we deal with most often:
- Galvanized supply lines behind the walls. Homes built from the 1950s through the mid-70s often have galvanized steel pipe that’s rusted shut from the inside. You won’t know it until we open the wall behind the vanity or tub, and when we do, the city requires us to bring the affected plumbing to current code.
- Undersized or notched framing around tubs and showers. The original framers weren’t thinking about 2026 building codes. When we open a 1960s San Bernardino shower wall, it’s common to find 2×4 studs notched past allowable depth for the old drain. That framing has to be sistered or replaced before we can close the wall back up.
- Failed waterproofing behind original tile. Those 1950s – 70s showers were often built as mortar beds with minimal membrane, and after four or five decades, the grout is shot and the substrate behind the tile is wet. Sometimes the studs are fine. Sometimes they’re not. The only way to know is to open it up.
- Pinhole leaks in early copper supply lines. Post-1970 homes in San Bernardino often used thinner Type M copper. Pinholes develop, especially with the minerals in the city water. When we repipe for a remodel, we upgrade to Type L copper or PEX, whichever the job calls for.
Pricing for Bathroom Remodeling in San Bernardino, CA
Here’s what we’re seeing in San Bernardino as of 2026. A hall bath remodel that mostly updates finishes runs $18,000 – $26,000 when the framing and plumbing are clean. A hall bath with a tub-to-shower conversion and repiping runs $26,000 – $38,000. A primary bath with a walk-in shower, double vanity, and new lighting runs $32,000 – $65,000 depending on fixtures and square footage. Where older San Bernardino homes with galvanized plumbing and hidden framing damage are involved, we build a contingency allowance into the contract so you know the high end before we start.
Every bid is line-item. You’ll see the cost for demolition, plumbing, electrical, tile, fixture allowances, and our project management fee separately. If we open a wall and find something that changes scope, you get a written change order with photos and a fixed price before we do one more hour of work. That’s how Noel Carrasco runs every job, and it’s the reason our San Bernardino customers aren’t afraid to open their walls. Call (877) 265-9846 for a free estimate and we’ll walk your San Bernardino bathroom with you, wall by wall.
How We Handle Surprises in Older San Bernardino Homes
In San Bernardino’s 92404 and 92405 ZIPs, the original detached garages facing narrow alleys often trigger a parking replacement when converted. But bathroom remodels in these same homes hit a different snag: the 1950s – 70s stucco tract construction usually hides galvanized supply lines and undersized framing that only surface once walls are opened, and those code upgrades can add 20 – 30% to a bathroom budget. That’s the single biggest reason bathroom remodel quotes move on these homes, and it’s exactly why we structure our contracts the way we do.
We inspect first. Before we sign anything, we open the access panel behind the tub, check the water pressure, look at the crawlspace if there is one, and check the vent stack. We can’t see everything before demolition, but we can usually see enough to write a realistic allowance. Then, when work starts, anything we find gets priced and approved in writing before we touch it.
Our crew was remodeling a hall bath in a 1962 tract home near Del Rosa Avenue in the 92404 ZIP when we opened the wall behind the tub and found galvanized supply lines corroded shut and 2×4 studs notched past code for the old drain. We stopped work, wrote a change order with photos and a fixed price, and got the homeowner’s written approval before replacing the plumbing and sistering the framing. The finished bath passed inspection with upgraded copper and proper waterproofing. That’s the process every single time.

FAQs – Bathroom Remodeling in San Bernardino
Usually yes, at least for the portion of the system we’re accessing. Once the wall is open and the city inspector sees galvanized supply lines, San Bernardino code requires bringing the exposed plumbing up to current standards. We’ll repipe the affected runs in Type L copper or PEX as part of the remodel, and we can quote the whole-house repipe separately if you’d rather address it all at once. Call (877) 265-9846 and we’ll give you a straight answer on your specific home.
Not automatically. The city requires the circuits we touch in the bathroom to meet current code, which often means adding a dedicated 20-amp circuit for the vanity outlets. If your panel is decades old and we’re already adding circuits, the inspector may flag it, but that’s a case-by-case call. We’ll tell you before you commit.
We stop, document it, and price it before we repair anything. You’ll get photos, a written change order with the exact scope, and a fixed price. If you approve, we sister or replace the affected studs, get the rough framing inspection passed, and then keep going. If you don’t approve, we close up at the original scope. Nothing gets touched without your signature.
San Bernardino code requires a waterproof membrane behind the shower walls and a properly sloped pan. We use Schluter systems for most showers: a bonded membrane that doesn’t get brittle in the Inland Empire’s dry heat and handles the temperature swings between summer and Santa Ana season without cracking. It’s more reliable than the old mortar beds that failed in so many San Bernardino homes.
Bathroom remodels don’t trigger the parking replacement requirement. That applies when you convert a detached garage to an ADU. But if you’re doing both, plan for the parking replacement on the garage side of the project, which usually means restriping the driveway. We’ll flag it during the estimate so it doesn’t catch you off guard.
