Kohler Construction in San Martin, CA | Timberline Contractors
We install, repair, and rebuild Kohler plumbing and bath fixtures in San Martin, CA as a San Martin General Contractor. What makes our Kohler work different here is that we plan every sink, tub, and shower rough-in around Santa Clara County’s permit process and the hard well water that runs through most San Martin parcels. If you’re planning a kitchen or bath remodel, call (866) 253-5808 for a free estimate before you buy the first fixture.
Why San Martin Residents Choose Us for Kohler Service
We’ve pulled apart enough Kohler fixtures in San Martin to know exactly where they fail. Not where they fail in a showroom or a tract home in Morgan Hill, but where they fail on a well-fed ranch house with water that leaves scale on a shower cartridge in eighteen months. Nelson Fung, our owner and general contractor, grew up around material selection the way some kids grew up around baseball cards. That background in knowing what’s worth paying for and what isn’t shapes how we approach every Kohler job. We keep OEM Kohler cartridges, flush valves, and trim kits on hand for the models we see most in San Martin, which means a repair doesn’t turn into a two-week waiting game while a part ships from Wisconsin. Our team works under the Kohler sales & service umbrella we maintain across all our service areas, so when a client calls about a leaking Purist valve or a chipped Whitehaven sink, we’re already thinking in terms of what that fixture will do in five years, not just this week.

Common Kohler Construction Problems We Solve in San Martin
- Katalyst showerheads that clog and lose pressure. The silicone aerator screens and check valves inside Kohler Katalyst showerheads collect mineral deposits from San Martin well water years before a municipal-water home would notice a drop in pressure. We replace the aerator screens and rebuild the check valve with OEM parts when available, and we’ll tell you honestly when a sediment filter at the well head is the better long-term fix.
- Chips and cracks around cast-iron sink and tub drain collars. Water hammer from aging well pumps cycles through a house every time a valve closes. On Kohler cast-iron kitchen sinks and Bellwether tubs, that hammer vibration works the drain collar against the porcelain. We see chips at the drain collar on San Martin properties with older well systems, and we can often address the water hammer at the source while repairing the enamel damage.
- Toilets that weep and short-cycle. Kohler Memoirs and Highline toilets with Class Five or AquaPiston flush valves handle sediment poorly. When San Martin well water carries grit through the refill tube, the fill valve starts weeping and the toilet cycles on its own. It’s one of the most common service calls we get, and it’s almost always a valve replacement rather than a full toilet replacement.
- Kohler bath caulk and cartridge seals that shrink and leak. San Martin swings from hot, bone-dry summers to wet winters. The factory caulk on Kohler tub and shower surrounds expands and shrinks through that cycle until it separates. Ceramic cartridge seals inside the valve body do the same. We correct the caulk with a proper silicone and rebuild or replace the cartridge before water gets behind the wall.
- Rough-ins that need to clear the County, not a city hall. This one isn’t a fixture failure, but it bites homeowners just the same. San Martin has no municipal building department, so any Kohler shower valve or bathtub drain relocation in a remodel needs Santa Clara County permit sign-off. We handle that submittal as part of the construction scope, because a failed inspection is a far more expensive problem than a leaking cartridge.
Kohler Service in San Martin: What Local Conditions Mean for Your Equipment
Because San Martin is unincorporated Santa Clara County, any cabinetry, sink, or shower rough-in change inside a Kohler kitchen or bath remodel has to clear the County permit counter, not a San Martin city hall, because there isn’t one. That county sign-off folds plumbing rough-in, well and septic coordination, and sometimes drainage review into the same submittal in a way Morgan Hill or Gilroy across the line never requires. For a Kohler owner, that means a simple tub-to-shower swap can trigger a well flow test or a septic tank location review before a single wall is opened. We’ve walked enough of these through to know which questions the County reviewer will ask before we draw the plumbing plan. On the valley-floor custom homes off the Llagas Creek flood corridor, for example, we redid a bath where a Kohler Bellwether tub and Purist shower valve fed off the property’s well, and sediment had chewed the Katalyst shower cartridge and left water-hammer chips around the tub drain. We pulled the cast-iron tub for a curbless walk-in shower with Kohler Katalyst trim and a sediment-screened rough-in, then walked the county permit closeout on the plumbing change the same week. That’s the difference between a contractor who has done county work in San Martin and one who just adds the ZIP code to a service map.
Kohler Models & Products We Service in San Martin
We work on most Kohler fixture families that turn up in San Martin homes. That includes the cast-iron kitchen sink line, Cape Dory and the Whitehaven apron-front models included, the Purist and Katalyst shower systems, the Memoirs and Highline toilet lines, and the Bellwether and Archer bathtub families. Our parts approach is simple: we stock genuine Kohler OEM cartridges, flush valves, aerators, and trim wherever the fixture is worth preserving, and we use only vetted aftermarket parts on high-wear items like aerator screens when OEM lead times would stall a job. If the porcelain or enamel is sound, we repair rather than replace. Once a cast-iron tub or apron sink has cracked through the enamel, replacement is the honest call, and we’ll tell you so before you spend money on a repair that won’t hold.

AfterKohler Service Pricing in San Martin
Kohler service pricing in San Martin reflects the scope of the work, not the brand name on the fixture. A cartridge rebuild on a Purist shower valve runs a few hundred dollars in labor and parts; a full bathroom remodel with a Kohler Bellwether tub and Katalyst shower conversion is a different conversation. We provide written line-item estimates so you can see exactly what a fixture or rough-in change costs before we start. Here’s what we typically see for Kohler-related construction work across San Martin:
| Service | Price Range |
|---|---|
| Full Bathroom Remodeling | $9,000 – $28,000 |
| Walk-In Shower Installation | $4,500 – $12,000 |
| Tub-to-Shower Conversion | $3,500 – $10,000 |
| Full Kitchen Remodeling | $14,000 – $45,000 |
| Countertop Installation | $2,000 – $6,500 |
What drives cost is the condition of the plumbing behind the wall, whether the County requires a well or septic review for the rough-in change, and which Kohler fixture you’re installing. A free estimate from us includes the inspection of the existing plumbing and a straight answer about what needs replacing. Call (866) 253-5808 to set one up.

FAQs – Kohler Construction in San Martin
No municipal inspection exists in San Martin because the area is unincorporated Santa Clara County, but a county permit is still required when the sink installation changes drain or supply plumbing. A simple drop-in replacement of the same sink footprint may not need a permit, but moving a drain line for a Kohler Whitehaven apron-front sink or changing the cabinet and countertop layout usually triggers a county rough-in review. We confirm permit requirements before we start. Call (866) 253-5808 and we’ll check your specific situation.
Hard well water on unincorporated San Martin parcels loads the silicone aerator screens and check valves in Katalyst showerheads with mineral deposits far faster than Corralitos Kohler service or Gilroy’s municipal water supply would. The fix is usually straightforward: replace the aerator screens, rebuild the check valve, and add a whole-house sediment filter if the well is pumping grit. That last step is what prevents the same repair from repeating in eighteen months. Call (866) 253-5808 for a free estimate on the repair and the filter option.
In most San Martin homes on a well, a Kohler Memoirs or Highline toilet that weeps or short-cycles is worth repairing if the porcelain bowl and tank are intact. The failure is almost always in the fill and flush valve assembly, which we replace with OEM Kohler parts. The decision to replace comes when the bowl has hairline cracks from hard water stress or the home is already in a remodel and wants a more water-efficient model. We’ll tell you honestly which path makes sense for your fixture. Call (866) 253-5808 for an exact assessment.
If your San Martin property sits in or near the Llagas Creek flood corridor, the County may require drainage and grading review as part of any remodel that changes the building footprint or affects site runoff. For a Kohler bath remodel, that usually means the bathroom stays inside the existing footprint and we coordinate the plumbing rough-in with whatever site drainage conditions are already on file. The goal is to avoid triggering a floodplain review for work that shouldn’t need one. We handle that coordination as part of the permit package. Call (866) 253-5808 to discuss your lot’s situation.
No. Older San Martin ranch houses built before standard setback and plumbing codes still fall under Santa Clara County jurisdiction today, and we always pull the permit for any Kohler vanity or shower install that changes water supply, drain location, or wall framing. The risk of skipping a permit isn’t just the fine. It’s the problem when you sell the house and an unpermitted shower rough-in surfaces in escrow. We do permit work first. Call (866) 253-5808 for a free estimate that includes the county permit cost up front.
