AfterKohler Construction in San Antonio, CA | Rowan Construction Group
We service, install, and remodel with Kohler fixtures across San Antonio as an independent contractor - not a manufacturer-authorized shop, which means we answer to you and to the building science, not to a parts quota. What makes our Kohler work here different is that we plan every fixture installation around the Balcones Escarpment: expansive clay on one side of town, solid limestone two feet down on the other, and aquifer-driven water chemistry that calcifies cartridges faster than anywhere we’ve worked. If you’re in San Antonio and need a Kohler bathroom built right against these conditions, call (470) 298-9650 for a free estimate.
Why San Antonio Residents Choose Us for Kohler Service
Grant Rowan founded this company in 2007 after training in construction technology at Los Angeles Trade-Technical College, where the coursework covered framing, concrete, and estimating before he ever swung a hammer on a paying job. That sequence stuck: we estimate first, document everything, and write the price before tools come off the truck. When it comes to Kohler, our crews know the Purist and Artifacts collections down to the ceramic disc cartridge, we stock genuine Kohler seals and trim locally, and we’ve spent years learning which models hold up to San Antonio‘s hard Edwards Aquifer water and which need rough-in modifications before they’ll sit right on your slab. We’re licensed, insured, and background-checked, and every visit ends with a photo record of what we found and what we did - not a summary, the actual evidence.
Common Kohler Construction Problems We Solve in San Antonio
Here’s what we see repeatedly across San Antonio, tied directly to local conditions rather than generic wear:
- Purist and Artifacts wall-mount faucets leaking at the cartridge. San Antonio water is hard - rich in calcium and magnesium from the Edwards Aquifer - and those minerals calcify the inlet seals on the ceramic disc cartridge. The faucet drips even after you crank the handle tight. We replace the cartridge with a genuine Kohler part, not an aftermarket one that rarely holds tolerance in our water.
- Highline toilets rocking and leaking at the flange on post-tension slabs. Drought cycles shrink expansive Vertisol clay, the slab shifts, and the toilet develops a subtle rock. The wax seal breaks, and you get a sewer-gas smell or a slow flange leak. On northside and east side San Antonio homes sitting on 1970s-90s slabs, this is one of the most common Kohler issues we see.
- Acrylic shower bases flexing and cracking over uneven limestone. Kohler’s lower-tier shower bases are well-molded, but they need a dead-flat substrate. On northside remodels where the subfloor sits over shallow Edwards limestone, minor variation translates into flex, then a stress crack at the corner of the drain.
- Push-button flush actuators binding with mineral buildup. The flush buttons on newer Kohler toilets like the Highline and newer Wellworth models use a spring-loaded mechanism that’s prone to binding when hard-water scale accumulates. It starts as a stiff flush, then the button refuses to return.
- Freestanding tubs that rock because the floor is no longer level. This is the San Antonio-specific one. On pre-1970 pier-and-beam homes, decades of Vertisol expansion and contraction leave bathroom floors out of plane by an inch or more. A Kohler freestanding tub installed on that floor will rock - the tub isn’t defective, the floor is.
BeforeAfterKohler Service in San Antonio: What Local Conditions Mean for Your Equipment
San Antonio sits on a geological split that most out-of-town Kohler installers never account for. South and east of downtown, the soil is deep Vertisol clay - highly expansive. It shrinks during drought, swells with rain, and moves post-tension slabs enough to break toilet flanges and shift rough-ins. North and northwest - Stone Oak, Helotes, the IH-10 corridor - you hit Edwards limestone two to four feet below grade. That’s a brutal trenching condition for anyone running new plumbing for a Kohler shower or freestanding tub, and it means a one-day utility run can become a three-day rock-cutting job. On a 1960s home off West Avenue near San Antonio College, we recently pulled an old cast iron tub to install a Kohler Artifacts freestanding model. The joists had sagged one and a quarter inches over a pier that had settled into dry clay. We sistered the joists, set a concrete block pier on undisturbed soil, poured a self-leveling bed, then set the tub. Two months later the owners confirmed it still doesn’t rock. That’s the difference between installing Kohler and installing Kohler for a ten-year service life in San Antonio. Any construction within the Edwards Aquifer Recharge Zone also carries strict SAWS drainage requirements that affect bathroom remodeling when it changes the building footprint or drainage pattern - we factor that into your quote before anyone breaks ground.
Kohler Models & Products We Service in San Antonio
We work on the full Kohler bathroom line: Purist and Artifacts faucets, showers, and tub-fillers; Highline and Wellworth toilets; Tresham vanities; and the full range of shower bases, bathtubs, and wall-hung fixtures. Our parts policy is simple: genuine Kohler cartridges, seals, trim, and flush mechanisms for anything inside the valve body. Aftermarket internals don’t hold tolerance with San Antonio’s hard water, and we won’t put one in. We stock common Kohler service parts locally so turnaround is measured in days, not weeks. For full bathroom remodels in San Antonio, we also plan around rough-in depth, slab condition, and drainage slope before fixtures ever arrive. When you need broader Kohler context, review our Kohler sales & service page.

FAQs - Kohler Construction in San Antonio
Yes. On post-tension slabs, we anchor Kohler tubs and shower bases to the slab using mechanical anchors sized for the fixture’s weight and the slab’s known movement history. We also check the rough-in elevation before setting the fixture, because slab settlement can leave a drain stub too high for a proper gravity flow. Call (470) 298-9650 for an exact inspection of your slab condition before you buy the fixture.
Usually, yes. Kohler Highline toilets sit on a 12-inch standard rough-in, which matches most 1990s production homes in San Antonio. The issue isn’t the rough-in measurement; it’s the flange condition and slab flatness beneath it. We inspect the flange, test for rocking, and if the slab has shifted, we shim and seal before mounting. It’s a quick check that prevents a recurring toilet rock on a shifted slab.
Yes, and this is where northside San Antonio homes actually help. Limestone subfloor is stable, which means we can set a Kohler shower base or a custom-sloped mortar bed with confidence it won’t move. The main constraint is slope: we need a minimum quarter-inch per foot toward the drain, and sometimes the existing drain elevation dictates whether you can go curbless without raising the floor. We’ll lay it out for you before any demo begins.
Hard water from the Edwards Aquifer deposits calcium carbonate on the cartridge and the handle stem, so the mechanism binds. We disassemble the valve, soak or replace the affected internal parts, and use genuine Kohler replacement cartridges - aftermarket cartridges seal with softer rubber that hard water degrades even faster. If the problem is chronic, we can recommend a Kohler model with a different cartridge design that tolerates our water better. For a specific quote on a cartridge rebuild, call (470) 298-9650.
Repairing is worth it if the cast iron body is intact and the problem is surface enamel wear, a failing drain assembly, or a worn shoe gasket. Cast iron holds up extremely well. If the tub is rocking, sitting on a settled floor, or the enamel has worn through to bare metal in multiple spots, replacement is usually the better number over time. We’ll tell you which one applies to your tub, not which one profits us more.
