Kohler Construction in Highgrove, CA | Polaris Contractors
We provide independent Kohler service across Highgrove, from faucet cartridge swaps to full walk-in shower system installs. The thing that makes our Kohler work different here is simple: we build and renovate on Highgrove’s expansive clay soil every week, so we know what happens to a cast-iron tub base when the ground under a 1963 slab decides to move. Call (855) 473-6535 for a free estimate. We’re Kohler sales & service specialists, and we’ve been setting Kohler fixtures in Inland Empire homes long enough to know which job needs a cartridge and which one needs a new subfloor.
Why Highgrove Residents Choose Us for Kohler Service
Most contractors can swap a faucet. What we do differently is understand how Kohler products actually behave after a decade of Highgrove’s hard water and 105°F August afternoons. Rick Sondermann, our owner, grew up around finish carpentry and has spent the better part of three decades on job sites where a poorly set shower pan meant ripping out tile two years later. That’s why we check the subfloor before we set a Kohler base, and why we stock genuine Kohler cartridges and flush valves instead of gambling on aftermarket copies. For homeowners across the Highgrove service area, that means one call gets you a crew that knows both the fixture and the ground it sits on.
We’re a full-scope general contractor, not a Kohler dealer. That matters in Highgrove because so many Kohler repairs are actually foundation-and-tile problems wearing a plumbing costume. When your cast-iron tub rim is chipped and the tile bed around it is cracked, you need someone who can level the slab, set the pan, plumb the valve, and tile the surround, all under one contract. That’s the job we do.

Common Kohler Construction Problems We Solve in Highgrove
- Ceramic disc cartridges seizing or dripping. Highgrove’s water carries a heavy mineral load, and after a few years that scale works its way into the cartridge seats on Kohler Purist and Simplice faucets, especially on laundry sinks and garage-adjacent hose bibs. We replace with genuine Kohler OEM cartridges because aftermarket versions fail fast in this water chemistry.
- AquaPiston and Class Five flush valves running constantly. Sediment and hard-water scale build on the flush valve gasket in Kohler Memoirs and Devonshire toilets until the seal no longer holds. The toilet runs, the water bill climbs, and the fix is a gasket and seal clean-out, not a new toilet.
- Cast-iron tub and shower bases rusting at the drain and rim. Highgrove’s older homes, mostly built from the 1950s through the 1970s, often sit on slabs that shift with the expansive clay underneath. When the slab moves, the tile bed around a Kohler Villager or Cape Cod base cracks, water seeps through, and the cast iron starts rusting at the drain flange and rim.
- Finish pitting and flaking on polished chrome and brushed nickel. Highgrove summers routinely exceed 100°F, and bathrooms with weak ventilation cycle between hot and humid and bone dry. That cycling degrades the plating on Kohler trim over time, especially on shower valves and tub spouts. We can replace trim kits in matching finishes without tearing out the wall.
- Cracked shower pans from slab movement. This is the one we see most often on unincorporated Highgrove parcels. The clay soil dries out, the slab settles unevenly, and a Kohler shower pan that was set directly on a moving slab cracks at the drain. The repair is a level-and-set job, not a caulk line.
Kohler Service in Highgrove: What Local Conditions Mean for Your Equipment
Here’s the thing about Highgrove that doesn’t show up on a generic Kohler service page: much of this community sits on unincorporated Riverside County land where the soil is expansive clay. During the dry season, that clay shrinks. Slabs settle, hairline cracks appear, and anything rigid, like a cast-iron Kohler tub base or a mortared shower pan, takes the stress. We’ve pulled Kohler Villager tubs out of 1960s ranch homes off Center Street where the base had cracked the surrounding tile bed as the ground moved underneath it—similar to what we see with Kohler service in Rubidoux. If you just tile over that moving slab, you’ll get the same cracks again next dry season. So before we set any Kohler fixture in Highgrove, we check and level the subfloor. Sometimes that means a mud bed. Sometimes it means a moisture-controlled pan. It always means the fixture drains clean and doesn’t rock when the clay shifts again. That’s the difference between a patch and a repair, and it’s what our Kohler work in Highgrove is built around.
Kohler Models & Products We Service in Highgrove
We service and install the Kohler lines most common in Highgrove homes—just as we do with Colton Kohler service: Memoirs and Devonshire toilets with Class Five and AquaPiston flush platforms, Purist and Simplice faucet lines, Choreograph and LuxStone shower wall systems, and Villager and Cape Cod cast-iron bath and shower bases. Our parts approach is straightforward. For anything that touches water or finish, we use genuine Kohler OEM cartridges, flush valves, and trim kits. Aftermarket copies fail quickly in Highgrove’s mineral-heavy water, and a failed cartridge means a callback neither of us wants. For discontinued trim where OEM is truly unavailable, we source quality aftermarket parts and tell you exactly what you’re getting before we install it.

AfterKohler Service Pricing in Highgrove
What you’ll pay depends on the scope, not on guesswork. A tub-to-shower conversion runs less than a full walk-in shower build because the drain location stays put and the plumbing rough-in is already there. Here are the ranges we work within for Kohler-related bathroom work in Highgrove:
| Service | Price Range |
|---|---|
| Walk-In Shower Installation | $4,500 – $12,000 |
| Tub-to-Shower Conversion | $3,500 – $10,000 |
| Bathroom Vanity Installation | $800 – $3,000 |
| Small Bathroom Remodel | $5,000 – $12,000 |
| Shower Replacement | $3,000 – $8,500 |
The variables are tile choice, glass enclosure, and whether the subfloor needs leveling, which in Highgrove it often does. Every estimate includes a written line-item breakdown so you know exactly what you’re paying for before we start. Call (855) 473-6535 to schedule yours.

FAQs – Kohler Construction in Highgrove
On Kohler Memoirs and Devonshire models, a constantly running toilet is almost always the flush valve gasket losing its seal, not the fill valve. Highgrove’s hard water leaves scale on the AquaPiston or Class Five gasket until it can’t hold water anymore. We replace the gasket and clean the seal surfaces, which fixes the run without replacing the toilet. Call (855) 473-6535 if it’s been running for more than a week, because that’s real money going down the drain.
Yes, but not directly on the slab. We level the subfloor first, usually with a mud bed or a moisture-controlled pan, so the Kohler base sits on a stable surface that won’t telegraph the slab’s movement into the fiberglass or cast iron. Setting a base directly on a moving Highgrove slab is how you get a cracked pan and a tile bed that fails next dry season.
If the cast iron is sound and the finish is intact, a Kohler Villager or Cape Cod tub is worth refinishing and keeping. But if the drain area is rusted through or the surrounding tile bed is cracked from slab movement, a tub-to-shower conversion using a Kohler Choreograph or LuxStone system usually makes more sense. You get a walk-in shower that drains clean and won’t shift when the clay soil moves. Call (855) 473-6535 and we’ll tell you straight which way to go.
It might fit, but fit isn’t the problem. The problem is that many online cartridges are aftermarket copies that fail within a year in Highgrove’s hard water. We use genuine Kohler OEM cartridges because they’re built for the ceramic disc tolerances that keep a Purist or Simplice faucet drip-free. If you already bought a part, we’ll inspect it and install it if it’s genuine. If it’s not, we’ll show you the difference before we proceed.
Yes, and that’s actually where we do our best work, including Kohler in Grand Terrace. We’re a full-scope general contractor, so a Kohler tub-to-shower conversion, a new vanity, and a kitchen faucet swap can all be handled under one contract with one crew. You’re not calling a plumber for the fixture, a tile guy for the surround, and a carpenter for the vanity. One team, full scope, start to finish. Estimates are free at (855) 473-6535.
