Kohler Construction in Cupertino, CA | Milpitas Construction
We’re Milpitas Construction, and we provide independent Kohler fixture installation, service, and repair across Cupertino, ZIP codes 95014 and 95015. Our Kohler work here is shaped by one local reality more than anything else: most of Cupertino’s Eichler and rancher homes hide radiant heating coils in the slab, which means swapping a tub or re-plumbing a shower drain is a structural puzzle, not a quick swap. That’s why our Kohler service in Cupertino starts with mapping what’s under the floor before we ever pick up a cutting tool. Call (877) 752-4194 to schedule a free estimate.
Why Cupertino Residents Choose Us for Kohler Service
Ken Stafford, our owner, grew up near the Milpitas BART corridor back when those lots were warehouse space and family shops, and he’s spent the two-plus decades since learning what holds up in Bay Area soil and seismic conditions. That background matters when you’re installing Kohler cast iron tubs and Purist shower valves in Cupertino’s mid-century shells, and it’s the same expertise we bring to Kohler repair in Los Altos. We don’t treat a Kohler fixture like a generic part. We spec OEM cartridges, flush towers, and trim where Kohler still produces them, and we’re honest when a 40-year-old Villager tub has failed beyond repair. For full bathroom remodels, walk-in shower conversions, and tub-to-shower work, Cupertino homeowners get one team that knows both the fixture and the floor it sits on.

Common Kohler Construction Problems We Solve in Cupertino
Here’s what we actually find when we open up Cupertino bathrooms built between 1950 and 1980:
- Cast iron tub enamel failure. Original Kohler Villager and Memoirs alcove tubs in Cupertino’s tract homes are now 50 to 70 years old. The porcelain enamel crazes, then rust blooms at the drain and overflow. The original lead-oak drain connections weep once the tub gets disturbed during even a minor remodel. On those, we usually recommend a current Kohler cast iron replacement rather than trying to patch old enamel.
- Rite-Temp valve cartridge seizure. Cupertino’s water runs hard and mineral-heavy. Kohler Rite-Temp and older pressure-balance cartridges stiffen and seize, so you get temperature swings or a shower that won’t hold hot water. We find this most often mid-remodel, once the wall is already open, which is the cheapest time to replace the cartridge with an OEM unit.
- Cimarron and Wellworth flush tower wear. The class-five flush towers in Kohler Cimarron and Wellworth Comfort Height toilets wear out and cause phantom running or weak flushing, especially in Cupertino homes remodeled ten to fifteen years ago. Sometimes the fix is a $30 OEM seal; sometimes the toilet’s done.
- Vitreous china cracking during tub removal. Undermount bathroom sinks and one-piece toilets can crack at the rim or trapway when a cast iron tub above them comes out and the original subfloor or slab gets cut. That’s a real risk on Cupertino’s radiant-slab floors, and it’s why we cut conservatively and support the surrounding floor before we pull a tub.
- Out-of-plumb rough-ins on slab foundations. Cupertino’s older homes have settled over the decades, which means tub and shower rough plumbing rarely lines up with new Kohler trim the way the spec sheet assumes. We correct the rough-in before the fixture goes in, or you’ll fight the alignment forever.
Kohler Service in Cupertino: What Local Conditions Mean for Your Equipment
Most of Cupertino’s Eichler-style and low-pitch ranchers have original radiant heating coils cast directly into the slab. Pull an old Kohler cast iron tub and re-plumb a shower drain, and you’re mapping in-slab tubing before any concrete gets cut. Off Voss Avenue, we opened a 1962 low-slope rancher’s hall bath with an original Kohler Villager, crazed enamel, and a Rite-Temp valve that wouldn’t hold temperature. We mapped the radiant slab first, removed the tub, set a Kohler cast iron shower base, replaced the valve cartridge with an OEM unit, and finished the stall with frameless glass. The homeowners got their walk-in shower without nicking a single heating loop. That slab complication is exactly why a straight tub-to-shower swap in Cupertino is rarely a one-day job, no matter what anyone tells you.
Kohler Models & Products We Service in Cupertino
We work on Kohler Villager and Memoirs cast iron alcove tubs, Purist and Loure shower trim with Rite-Temp pressure-balancing valves, Cimarron and Wellworth Comfort Height toilets, and Artifacts and Bellera widespread faucets. We stock OEM Rite-Temp cartridges, flush towers, and common trim in the truck for fast Cupertino turnaround, since those are the parts that fail most often in local water conditions. When a Kohler line is discontinued, we turn to quality aftermarket suppliers rather than gambling on knockoffs. Our Kohler sales & service knowledge covers both the product lines that are still in production and the ones original to Cupertino’s 1950s-70s housing stock.

FAQs – Kohler Construction in Cupertino
Yes, and we do it regularly. We map the in-slab radiant tubing before cutting, plan the new drain location around it, and then set the replacement Kohler base and valve. The tub comes out in pieces so we don’t put point loads on the slab. Call (877) 752-4194 for a quote on your specific Eichler layout.
Almost always the valve cartridge, not the water supply. Cupertino’s mineral-heavy water stiffens Rite-Temp and older pressure-balance cartridges, and once the internal balancing spool sticks, temperature control goes unstable. We replace the cartridge with a genuine Kohler OEM unit and the swing stops.
If the bowl and trapway are intact and the problem is a worn flush tower or fill valve, repair makes sense, usually under $150 in OEM parts. If the china has hairline cracks or the trapway is failing, we say replace it. Our pricing for full Cupertino bathroom remodels that include new Kohler toilets runs $9,000 to $28,000 while a targeted repair is far less. Call (877) 752-4194 and we’ll tell you which way to go.
Yes. Cupertino’s plan check and tree ordinance reviews are part of the job whether you’re doing a light remodel or a full gut. We pull permits, schedule inspections, and handle the paperwork while installing Kohler tubs, showers, valves, and toilets to code. City approvals don’t slow us down; they’re just part of the sequence.
No. We’re an independent contractor. We are not authorized, sponsored, or endorsed by Kohler. We source Kohler parts on the open market and spec OEM components where the part is still in production. Our independence means we call failures honestly, including when it’s time to replace rather than repair.
