Kohler Construction in San Francisco, CA | Mason Remodeling
We provide independent Kohler construction service across San Francisco, from fixture installation to full Bathroom Remodeling in San Francisco. We are not a Kohler-authorized dealer or manufacturer affiliate, and we are fine saying that plainly. What makes our Kohler work different in San Francisco is that we understand the city’s pre-1900 housing stock and how it affects every Kohler fixture that goes into it. Call (803) 680-2547 for a free estimate.
Why San Francisco Residents Choose Us for Kohler Service

We have installed and serviced Kohler fixtures in San Francisco’s Victorian and Edwardian homes for years. That matters, because working on a Kohler Cast Iron Tea-for-Two tub in a 1908 Marina flat is not the same as dropping one into a 1990s suburban bathroom. We know Kohler’s rough-in specs, finish-matching quirks, and where the plumbing will fight the framing before we open the wall.
Isaac Pruett, our owner, grew up watching his dad finish trim to a standard most people would not notice, then started doing his own remodeling work across Los Angeles after studying construction technology at LATTC, before becoming a General Contractor in San Francisco. His habit of checking trim work first on every project carries over to how we handle Kohler installs here. Every technician who walks through your door is background-checked, identity-verified, and arrives in a clean marked uniform with a photo ID badge. We send you their name and photo before the visit. That is the Threshold Standard, and it is how we have operated since Mason Remodeling started in 2004 as part of the Threshold Group.
Our Kohler sales & service work spans the full range of what San Francisco homeowners need, from swapping a failing cartridge to gutting a bathroom down to studs. We deliver a written price before any work starts, every time. No verbal estimates that grow later.

Common Kohler Construction Problems We Solve in San Francisco
- Cast iron tub enamel chipping and rust weep at the drain flange. In pre-1920 Victorian bathrooms, many Kohler cast iron tubs have been refinished over old rust instead of having it ground out. The enamel fails within a year, and you get that brown weep line at the drain. We grind out the rust properly or tell you honestly when a replacement is the better spend.
- Kohler ceramic cartridge failures in widespread lavatory faucets. San Francisco’s water chemistry is slightly aggressive, and main breaks dump sediment into the lines. That combination wears Kohler cartridges faster than the manufacturer’s average lifespan suggests. We replace them with genuine Kohler OEM cartridges so the faucet stops dripping and stays stopped.
- DTV+ digital shower valve control board corrosion. Damp, poorly ventilated interior bathrooms are common in San Francisco’s tight row-house layouts. Moisture gets into the DTV+ control board, the solenoids fail, and the shower refuses to turn on or cycles temperatures unpredictably. We replace the board and address the ventilation issue so it does not return in six months.
- NUMI toilet pump and bidet seat faults from hard-water scale. Years of scale buildup in tankless and tank-type units, especially where the toilet sits on a slab with no pan underneath, will kill the pump and the seat electronics. We can usually repair the unit by descaling and replacing the failed component, rather than pulling the toilet.
- Subfloor sag under cast iron Kohler tubs. Original post-and-pier framing in San Francisco Victorians has often sagged or been sistered poorly. A cast iron tub set on that floor will pull the drain away from the trap. We level and shim the subfloor before setting the tub, which is the difference between a drain that seals and one that leaks for years.
Kohler Service in San Francisco: What Local Conditions Mean for Your Equipment

Because San Francisco’s pre-1900 Victorian and Edwardian bathrooms were built for clawfoot tubs, Kohler Cast Iron Tea-for-Two and Iron Works tubs often sit on original post-and-pier framing that has sagged or been sistered. When we set a cast iron tub in these homes, we shim and level the subfloor first. If we do not, the drain will pull away from the trap and the tub will leak, usually into the ceiling below. We see this in neighborhoods like Noe Valley, the Mission, and Pacific Heights, where the housing stock dates to the same era and the framing carries the same hundred-year-old loads. A generic Kohler page will tell you the tub weighs three hundred pounds. It will not tell you what happens when that weight meets a sagging double-joist from 1906.
In a Noe Valley Victorian, we replaced a failing Kohler Cast Iron Tea-for-Two tub with deep enamel chipping at the drain. We swapped in a Kohler Archer shower base with a frameless glass enclosure, ground out the old rust, sistered two joists, and reset the drain to stop a slow leak that had stained the ceiling below. The owner also had us install a Kohler Memoirs vanity and a DTV+ shower, and the DTV+ control board was replaced under a service call for moisture corrosion before we closed the wall. That job is what we mean when we say we know Kohler in San Francisco, not just Kohler on a spec sheet.
Kohler Models & Products We Service in San Francisco

FAQs – Kohler Construction in San Francisco
In most San Francisco cases, we repair it. A NUMI that runs constantly usually has a failed fill valve or a scale-clogged pump, and a no-flush condition is often the bidet seat electronics or a failed solenoid. Both are replaceable parts, and we stock the common ones. Replacement is only the right call when the unit has multiple simultaneous failures and the cost to repair exceeds sixty percent of a new fixture. Call (803) 680-2547 and we will give you an honest repair-versus-replace answer.
Yes, and we do it correctly. We inspect the framing under the bathroom, sister or replace any sagging joists, and shim and level the subfloor before setting the tub. Skipping that step is why some cast iron tub drains pull loose in older San Francisco homes within a year or two of installation. Our work is covered by a written guarantee for 365 days from completion, and if a repair fails within that year, we return at no charge.
We replace the failed control board and solenoids, then we fix the moisture problem. That usually means a properly vented exhaust fan or a dehumidifier solution for windowless interior bathrooms. If we only swap the board and leave the damp air the same as before, you will be calling us again in a year. We would rather do it once. Call (803) 680-2547 for a free estimate on the repair.
Sometimes. Genuine Kohler OEM trim in discontinued finishes is limited to whatever remains in supply channels, and we can source it when it exists. When it does not, we present aftermarket options that match closely, after full disclosure of what you are getting. For a full remodel, we often recommend switching the visible trim to a current Kohler finish and keeping the discontinued finish only where the fixture is hidden. The pricing depends on what is available.
In San Francisco, expect $4,130 to $11,800, with the variance driven by the shower system you choose, whether we are relocating plumbing, and the condition of the subfloor and framing. A standard conversion with a Kohler Archer shower base, a wall kit, and a single-function valve is on the lower end. A DTV+ digital shower with body sprays, custom tile, and structural work runs higher. Call (803) 680-2547 for an exact quote, estimates are free.
