Fast, Reliable Bathroom Remodeling Across San Bruno
Bathroom remodeling in San Bruno typically runs $9,000 to $28,000 for a full renovation, with small bathroom remodels landing between $5,000 and $12,000. The range is wide for a reason: homes in Mills Park and Crestmoor were built in the 1940s and 1950s with cast-iron drains and 1×6 fir subfloors, while newer infill near the Transit Center sits on slab-on-grade with ¾-inch supply lines. Those two housing types demand very different scopes of work, and the first site visit usually tells us which side of the range your project will land on.
Our crews serve San Bruno neighborhoods from San Bruno Park to Rollingwood to Crestmoor every week. We know the permit sequence at the county counter, we know which inspectors want to see rough-in before the shower pan gets sealed, and we know exactly what a 70-year-old joist bay looks like when a wax ring has been seeping for decades. Call (803) 680-2547 and we’ll send someone who can scope your bathroom honestly against what San Bruno homes actually require, not a national average.
Why Mason Remodeling Is San Bruno’s Preferred Bathroom Remodeling Company
Every San Bruno homeowner who opens the door to a contractor makes a safety decision first and a remodeling decision second.

Their photo ID badge gets shown at the door, every time. Isaac Pruett oversees each project personally, and the person you meet at the estimate is the person accountable for the work.
Beyond who shows up, San Bruno customers keep calling us back because the price is in writing before any work begins.

And when the job is done, the 365-Day Done Right Promise covers your bathroom in plain terms: if the work is not right within a year of completion, we make it right at no cost to you. No dispute process, no conditions, no second-guessing.
Styles & brands we work with
Bathroom Renovation in San Bruno
Bathroom renovation in San Bruno means starting from the house you actually have, not a Pinterest board. A full renovation here involves gutting the room to the studs, addressing whatever the subfloor and drain lines reveal once the walls are open, and rebuilding with new tile, fixtures, vanity, lighting, and waterproofing. Homeowners in Mills Park, Rockspring, and Huntington typically need this when a tub surround has failed behind the tile, a floor has gone soft around the toilet, or the room simply no longer functions for a growing family or aging relatives.
Scoping a Full-Gut Renovation
A full-gut job in San Bruno runs $9,000 to $28,000. What separates the bottom of that range from the top mostly comes down to two things: whether you keep the original footprint and whether the subfloor survives the demo. Moving a toilet or shifting a drain line in a post-war raised-foundation home often means cutting into joists or rerouting 4-inch cast iron, and that’s where the price climbs fast.
What a Renovation Includes
A Mason Remodeling renovation includes demolition, haul-away, subfloor repair where needed, plumbing and electrical updates to current code, waterproofing, tile installation, fixture setting, vanity installation, and finish trim. We write every component into the scope of work with a fixed price, so you know before we start exactly what is included and what would cost extra.
Small Bathroom Remodel in San Bruno
A small bathroom remodel in San Bruno typically runs $5,000 to $12,000, which reflects the compact 5-foot-by-8-foot baths common in the post-war tracts of Mills Park and Crestmoor. These rooms were built tight intentionally – a 5-foot tub, a wall-hung lav, and a toilet all sharing one 4-inch cast-iron drain – and renovating them well means working within those dimensions rather than fighting them.
Working Within a 5×8 Footprint
Most small bathroom remodels in San Bruno keep the original footprint and focus on replacing what’s failing: swapping the tub for a walk-in shower, replacing a rotted subfloor, adding a vent where none existed, and updating the valve to a pressure-balanced Moen. Keeping the drain location saves thousands compared to moving plumbing across a joist bay.
The Subfloor Question
On a 1948 ranch in Mills Park, our crew pulled a Kohler cast-iron tub and discovered the subfloor had been sistered with 1×6 fir over a 4-inch cast drain line that no longer met current venting. We converted it to a walk-in shower with a Moen valve, brought the drain to 2-inch PVC, and ran new copper to the lav. The rough-in inspection passed on the first sign-off because we documented the joist repair in the scope of work before the tile went back. Total came in near the middle of our small bathroom band because the client kept the original footprint instead of moving the toilet.
Trusted Brands We Service in San Bruno
Mason Remodeling installs specification-grade fixtures and finishes from brands like Kohler, Moen, Toto, and Grohe, plus cabinetry from KraftMaid and surfaces from Cambria and Silestone. If you already have plumbing rough-ins from Abodu, Cover, or Dvele in a newer infill build near the Transit Center, we can carry the bathroom scope from window to finish and match the existing fixture language. We also maintain local parts access for San Bruno customers, so a replacement Moen cartridge or Kohler trim kit doesn’t leave your bathroom out of service for weeks.

AfterCommon Bathroom Remodeling Problems We See in San Bruno Homes
- Rotted subfloors beneath 1940s-1950s toilets. Decades of wax-ring seepage in Crestmoor and Mills Park homes have quietly rotted the plywood under the toilet flange. You don’t see it until the demo starts, and that’s why we do a subfloor check before finalizing any small bathroom scope, not after the tile is ordered.
- Cast-iron drain lines that don’t meet current venting codes. Homes built before the 1960s typically have 4-inch cast-iron drains with venting that predates modern plumbing code. When you open a wall to move a fixture, the inspector requires bringing the entire run up to current standard, which adds copper and PVC work to the plan.
- Slab-on-grade rough-in assumptions that don’t hold. Newer infill homes near the Transit Center have slab foundations, but plenty of San Bruno lots near San Bruno Park sit on raised foundations. If someone prices your job assuming slab-on-grade and you actually have a crawlspace, the drain routing changes, the plumbing allowance shifts, and a load-bearing wall might stand where the new drain needs to run.
- Missed rough-in inspection sequencing. San Bruno inspectors want to see the rough-in before the shower pan gets sealed. If the inspection sign-off is skipped and the tile goes up, the valve wall gets opened back up. We sequence inspections correctly from the start, and our scopes document every step the inspector needs to sign.

FAQs About Bathroom Remodeling in San Bruno
Does a bathroom remodel in San Bruno need a permit, and what does the inspection actually check?
Yes. Any San Bruno bathroom remodel that moves plumbing, modifies the drain line, adds a shower valve, or changes the electrical in a wet area requires a permit, and the inspection checks the rough-in – the drain slope, venting, water lines, and valve set – before the walls close. The inspector signs off on the rough-in, then the final inspection verifies fixture function and waterproofing. We pull the permits and schedule the inspections as part of the written scope, and every Mason Remodeling project includes passing inspections as a stated deliverable. Call (803) 680-2547 to get a scope that accounts for the full permit sequence.
What drives the price difference between a $5,000 small bathroom remodel and a $28,000 full one in San Bruno?
The gap comes down to square footage, whether you move plumbing, what the demo reveals, and finish level. A $5,000 – $12,000 small bathroom remodel in San Bruno keeps the footprint, replaces the shower or tub in place, and repairs the subfloor if needed. A $9,000 – $28,000 full remodel means gutting the room, possibly moving the toilet or a light fixture, upgrading cast-iron to PVC, and buying higher-grade tile, fixtures, and cabinetry. You should see the line items before you decide. Call (803) 680-2547 and we’ll show you both scopes.
How long does a San Bruno bathroom remodel take from demo to punch list?
A standard small bathroom remodel in San Bruno runs about 3 to 5 weeks, including demo, subfloor repair, rough-in, inspection, tile work, and fixture setting. A full renovation with moved plumbing and custom tile typically runs 6 to 10 weeks. The inspection calendar has a say too – we sequence the rough-in so the inspector signs off without holding your tile crew idle. Call (803) 680-2547 to get a schedule that reflects your actual scope.
Can you convert our existing tub to a walk-in shower without moving the drain?
Yes, in most San Bruno homes keeping the existing drain location is exactly how we keep a tub-to-shower conversion in the $3,500 – $10,000 range. The original tub drain often sits in a location that works for a walk-in shower, so we can install a shower base or a mud-bed pan, waterproof the walls, and set the new valve without cutting into joists to rerun drainage. If the subfloor has rotted around the drain, that changes the job, and we’ll show you exactly how before the tile goes in. Call (803) 680-2547 for a conversion quote.
What brands do you install, and how do allowances work if we want to pick our own fixtures?
We install Kohler, Moen, Toto, and Grohe fixtures as standard, with cabinetry from KraftMaid and surfaces from Cambria, Silestone, and Caesarstone. If you want to select your own fixtures from a showroom on the Peninsula, we build a fixture allowance into the written scope, and the allowance amount appears clearly in the price before we start. If you choose fixtures above the allowance, the overage is priced before the purchase, not after the work. Call (803) 680-2547 and we’ll walk the allowance line items with you.
