Kohler Construction in San Martin, CA | Seaside Contractors
We provide independent Kohler construction service across San Martin, California. That means full bathroom remodels, walk-in shower installations, vanity work, and fixture replacement using genuine Kohler parts. The reason our Kohler work here is different comes down to one thing: we know how Kohler fixtures perform on well water and inside ranch-era homes that were never built for modern plumbing retrofits. Call (833) 589-8103 for a free estimate, and we’ll tell you straight what the job actually needs.
Seaside Contractors handles Kohler projects from rough-in to trim. We’re the team that can pull a rusted Villager tub, re-run supply lines for your property’s mineral load, and install a Choreograph shower system that holds up through San Martin’s hot, dry summers. And because we’re a full-scope general contractor, we’re not limited to the fixture swap. We’ll manage the county permit, the wall repair, the waterproofing, and the finished tile. One contractor, every trade. For broader context on the work we do, see our Kohler sales & service page.
Why San Martin Residents Choose Us for Kohler Service
Most San Martin homes are mid-century ranches, farmhouses, or custom rural properties on multi-acre parcels. They run on wells. They sit on pier-and-beam subfloors or slabs poured decades ago. And their bathrooms were often plumbed when a single Kohler sink and a cast-iron tub were the whole show. Adding a second bath, converting a tub to a walk-in shower, or repairing a failing fixture here requires more than a parts catalog. It requires knowing how the house was put together and what the local conditions will do to the materials.
We’ve worked on homes off Llagas Road and throughout the 95046 zip code, and we understand what it takes to keep Kohler fixtures performing in this valley. Glen Sorrento grew up around construction along the Peninsula and spent the years since studying the framing, materials, and sequencing that make or break a remodel. He’s the one clients talk to when they want a straight answer on whether to repair a 30-year-old Kohler tub or replace it entirely. We use OEM Kohler cartridges and valves where fit and finish matter, and we’re upfront when a part is backordered or when a discontinued trim set should be replaced instead of patched together. Our service area extends through San Martin service area and covers the surrounding communities.

Common Kohler Construction Problems We Solve in San Martin
- Scale-clogged Forté and Simplice faucets. San Martin’s hard well water pushes calcium and magnesium into ceramic-disc cartridges fast. Faucets that should last 15 years start stiffening up or dripping in 5 to 7. We replace the cartridge with genuine Kohler OEM parts and can spec a whole-house sediment filter ahead of the fixtures so it doesn’t happen again in three years.
- Rusted-through Villager and Bellwether cast-iron tubs. Older ranch bathrooms in San Martin often have a tub sitting on a wood subfloor with seasonal moisture moving through it. The enamel crazes at the drain and overflow, then rust works through. We’ll inspect the tub, check the subfloor underneath, and tell you honestly if it can be re-enameled or if you’re better off with a Choreograph shower in the same rough-in.
- Loosening Choreograph shower panels and mildewed joints. When a shower is set against an exterior wall in a poorly ventilated rural bath, the temperature swing between the wall cavity and the shower surface stresses the sealant joints. We see this pattern in San Martin additions more than anywhere else. We re-seat the panels, replace the sealant, and address the ventilation so the problem actually stays fixed.
- Running Kohler flush valves on private wells. Sediment that gets past a worn whole-house filter clogs the fill and flush valves inside older Kohler one-piece toilets. The toilet runs constantly or needs a second flush. We replace the valve assembly and check the pre-existing filtration, because fixing the valve without fixing the sediment source just delays the next service call.
- Hard water damage on Kohler trim and showerheads. Mineral scale builds up inside the spray channels, reducing pressure and eventually seizing the fixture. We clean what’s serviceable and replace what’s not, using OEM trim when the wall rough-in still matches Kohler’s current lineup.
Kohler Service in San Martin: What Local Conditions Mean for Your Equipment
San Martin is unincorporated. Every Kohler bathroom or kitchen project here is permitted through Santa Clara County’s building department, not a city counter. That’s a quirk that doesn’t exist in Morgan Hill or Gilroy. You’d think swapping a toilet or converting a tub on a private home would be straightforward, but on a rural parcel with well and septic, the county wants to see the plumbing fixture changes on the plan set before they sign off. That adds weeks to a timeline. A contractor who only works city jobs will quote you city-speed and then watch the schedule stretch. We’ve learned to build that county review time into our San Martin estimates from day one, so the project doesn’t stall halfway through.
And the well water isn’t just a fixture problem. It’s a specification problem. When Glen walks a San Martin bathroom remodel, he’s looking at the mineral load coming out of the tap and thinking about what Kohler cartridge is going to survive it. Let’s figure out what the job actually needs, then we’ll talk materials. On a mid-century ranch off Llagas Road near Corralitos Kohler service territory, a homeowner wanted the original hall bath rebuilt around a Kohler Memoirs comfort-height toilet and a Forté widespread lav faucet. Our crew found the cast-iron tub rusted through at the overflow, so we pulled it in favor of a Choreograph walk-in shower with frameless glass, re-ran the supply lines to handle the property’s hard water, and added a whole-house sediment filter ahead of the new fixtures. The county permit on the septic-connected drain work meant the job ran longer than a city remodel, but the finished bath has held up cleanly through two summers.
Kohler Models & Products We Service in San Martin
We work across the Kohler lines most common in San Martin’s ranch homes and rural additions. That includes the Forté and Simplice faucet collections, Memoirs and Archer bath suites, Choreograph shower wall systems, and Bellwether and Villager cast-iron tubs. If you’ve got an older Kohler one-piece toilet with a sticky flush, we service that too. For parts, we use genuine Kohler OEM cartridges, valves, and trim where fit and finish matter. When a discontinued part is overpriced or gone from the market, we’ll recommend a proven aftermarket equivalent for consumables. On fixtures 25-plus years old with rust-through or cracked vitreous china, we’ll tell you straight when replacement beats repair. Kohler’s current lines install cleanly into the same rough-in, which saves you a wall tear-out.

FAQs – Kohler Construction in San Martin
Yes, in most cases San Martin plumbing fixture changes go through Santa Clara County because the community is unincorporated. A straight swap of a toilet or faucet on an existing rough-in might not need a full plan review, but any work that touches the drain, the supply lines, or a septic-connected waste line will. We pull the permits, submit the drawings, and handle the inspections. Call (833) 589-8103 and we’ll tell you what your specific job requires before we touch a wrench.
San Martin’s well water is hard, so calcium and magnesium deposit inside the cartridge and spray channels quickly. The fix has two parts: replace the cartridge or showerhead with a fresh OEM part, and install or upgrade a whole-house sediment filter ahead of the fixtures. Without the filter, you’ll be back in the same position in a few years. We’ll quote both pieces together so you’re not paying for the same repair twice.
Sometimes, if the rust is surface-level and the enamel damage is minor. But once the metal has rusted through at the drain or overflow, the tub is done. We see this on Villager and Bellwether tubs in San Martin’s pier-and-beam ranches where seasonal moisture attacks the underside. Re-enameling a rusted-through tub is a band-aid that fails. We’ll inspect it and give you an honest answer, because a Choreograph shower in the same footprint usually makes more sense.
Yes, it’s one of the better choices for this area. Choreograph panels install over a properly waterproofed substrate, they’re easy to clean, and they don’t have tile grout that mildews in humid rural baths. The catch is the sealant joints at the panel seams. If the wall behind them flexes, or if the bathroom lacks ventilation, those joints can fail. We install Choreograph with proper ventilation and wall prep so it doesn’t become a maintenance problem. For an exact quote on a walk-in shower conversion, call (833) 589-8103.
Hot, dry summers slow exterior work, but inside a bathroom or kitchen the bigger factors are humidity control and air quality. Concrete work, drywall compound, and paint cure differently when the air is dry or when smoke clogs a jobsite. We schedule the work around those seasonal conditions and protect open walls and fixtures from fine ash. It’s part of why our San Martin timelines are realistic from the start.
