Kohler Bathroom Remodeling: The San Antonio Owner’s Guide
A full Kohler bathroom remodel in San Antonio typically runs $9,000 to $28,000 installed, depending on scope, fixtures, and how much plumbing has to move. We keep Kohler-compatible trims, valves, and replacement parts on the truck for most common lines, so we can usually quote the job, order what’s not in stock, and start within a week. Most San Antonio homeowners don’t call us for a full remodel first though. They call because a Kohler valve started dripping, a cartridge seized up, or the tub spout diverter stopped sending water to the showerhead, and they want to know if they’re looking at a $300 fix or a $15,000 gut job.

Here’s what we tell them: if the tile is solid, the waterproofing is intact, and the plumbing layout still works, you’re often looking at a fixture-and-finish refresh in the $9,000 to $15,000 range. If we’re moving drains, replacing a tub with a walk-in shower, or fixing water damage behind the walls, the number climbs from there.
Key Takeaways
- Kohler bathroom remodeling in San Antonio: $9,000 – $28,000 installed, with small refreshes starting around $5,000.
- We stock common Kohler cartridges, trims, and shower valves, and can source OEM parts for older series within days.
- San Antonio’s hard water shortens Kohler cartridge life to roughly 5 – 8 years, so it’s rarely a fluke when a valve starts dripping.
- Sawyer Remodel San Antonio is an independent remodeler, not affiliated with Kohler. We install and repair their products because they hold up.
- Written price before work starts, 365-Day Done Right Promise, and live photo updates on every job.
Which Kohler Models This Applies To

The short answer: if it says Kohler on the trim plate, we can almost certainly match it. We work on the full range, but the ones we see most often in San Antonio houses are the Devonshire, Purist, Forte, Bancroft, and Mistral lines, along with the older Revival series that went into a lot of 1990s and early 2000s builds. The compatibility gotcha most homeowners don’t know is this: Kohler changed valve bodies over the years, and a Purist trim from 2004 won’t always fit a Purist rough-in valve from 2019. The trim looks nearly identical. The mounting holes and cartridge depth don’t match.
How to identify what you have: pull the handle trim off gently (it’s usually held by a set screw under a decorative cap) and look for a stamped number on the cartridge face or the valve body. Kohler stamps model numbers like K-304 or Rite-Temp K-8304 right into the brass. If you can’t find it, take a clear photo of the trim and the exposed valve. We match parts from photos all the time.
On the OEM versus aftermarket question: for Kohler shower valves and tub fillers, we recommend genuine Kohler OEM parts every time. Aftermarket cartridges for Kohler valves are a known weak point. The plastic grades differ slightly, the tolerances aren’t the same, and what saves you $40 on the part often costs you a call-back six months later when it starts seeping again. For non-plumbing items like grab bars, towel bars, and even some drain assemblies, quality aftermarket equivalents can work fine. But when water pressure is involved, we don’t gamble.

Signs Your Kohler Bathroom Remodeling Is Failing
Most Kohler fixtures don’t fail all at once. They degrade the way San Antonio’s water and heat break down anything with a seal or a plastic part. Here’s what we see:
- The handle sticks or feels gritty when turned. That’s mineral buildup inside the cartridge, which is inevitable with San Antonio’s hard water. Once the cartridge starts binding, the rubber seals wear unevenly and the drip usually follows within a month.
- A steady drip from the tub spout or showerhead. This means the cartridge’s pressure-balance seals have failed. In a Kohler Rite-Temp valve, that’s almost always a worn O-ring or a cracked pressure balance unit, not a pipe issue.
- The water only gets hot or only gets cold. That’s the pressure-balance spool inside that valve seized to one side. You can replace the cartridge, and we often do, but if the valve body itself has heavy mineral scaling, a full valve replacement sometimes costs less than fighting it.
- The diverter won’t send water up to the showerhead, or it partially does. On Kohler tub/shower combos, that little diverter gate wears out or gaskets flatten. The part is under $60. The labor to access it depends on whether the tile around the spout allows room to work.
- Water stains or soft drywall around the tub apron or shower curb. This isn’t always a Kohler part failure. It’s usually the caulking or waterproofing behind the tile that failed, but the Kohler drain assembly or tub overflow gasket can leak slowly for years before anyone notices. If you see a stain, we want to look before the subfloor rots.

AfterReplacement Cost & What’s Included

A Kohler bathroom remodel in San Antonio runs $9,000 to $28,000 installed. A small bathroom refresh with a new Kohler vanity, faucet, toilet, and shower trim typically lands between $5,000 and $12,000. A tub-to-shower conversion with a Kohler wall surround, new valve body, and glass door sits in the $3,500 to $10,000 range. A full gut-and-rebuild with a walk-in shower, custom tile, and a new Kohler freestanding tub pushes toward the top of that range, especially if we’re relocating plumbing in a slab foundation, which is common in older San Antonio neighborhoods like Jefferson or Tobin Hill.
What drives the cost: whether we’re working around existing valve locations or cutting into the slab to move them, whether waterproofing has to be rebuilt (it usually does), and which Kohler tier you choose. A Forte tub filler and a Purist freestanding tub filler are not even close in price. We give you the line-item breakdown before we start, and the invoice you approve is the invoice you pay. No surprise change orders. Our workmanship is backed by the 365-Day Done Right Promise: if it’s not done right, we make it right, in writing.
Here’s the price picture, line by line:

DIY or Call Us?
For a cartridge swap on a Kohler Rite-Temp valve, a careful owner with the right tool can do it. Kohler sells a plastic cartridge puller for about $15, and the process takes most people under an hour. The risk is minimal: turn off the water, pull the old cartridge, clean the valve body, seat the new one. But if you have an older valve with no integral shut-off stops, or the cartridge won’t come out after a decade of San Antonio hard water, stop. The worst outcome isn’t a leak; it’s cracking the valve body inside the wall trying to muscle out a seized cartridge. That turns a $300 service call into cutting open the shower wall.
Anything beyond a simple cartridge or showerhead replacement: call us. We’re the ones who know how Kohler valves should feel when they seat correctly, and we carry the tooling to extract stuck cartridges without breaking the brass. Call (432) 547-6806 and we’ll tell you over the phone whether it sounds like a cartridge, a valve body, or a waterproofing issue worth investigating before it spreads.
FAQs

With San Antonio’s hard water, plan on 5 to 8 years from a Kohler cartridge before it needs replacement. The fixture bodies, trim, and valves can last decades if they’re not abused, but the rubber and plastic wear parts inside are consumables. Tubs and sinks from Kohler’s enameled cast iron lines basically last forever unless they’re chipped. Call (432) 547-6806 if you need someone to assess what’s fixable.
Almost always yes. We replace the cartridge, clean the valve body, and flush the lines, and the leak stops. We only recommend full valve replacement when the valve body itself is cracked, the mounting threads are stripped, or the mineral buildup is so severe that repeated cartridge failures are inevitable. If repair is possible, we’ll tell you that and quote the repair. We don’t upsell replacement jobs that aren’t needed.
A fixture-and-trim refresh takes one to two days. A full remodel with tile, a new tub or shower, and waterproofing takes one to three weeks depending on scope. We give you a written schedule before we start, and we send photo updates before and after each major step so you’re never guessing what’s happening behind the plastic sheeting.
We stock common Kohler Rite-Temp cartridges, pressure-balance units, trim kits, and showerheads on the truck for the Devonshire, Purist, Forte, and Bancroft lines. For less common series or older discontinued trims, we source OEM from Kohler’s supply chain and typically have parts in hand within three to five business days.
Sawyer Remodel San Antonio is an independent remodeling company, not a Kohler dealer or authorized service provider. We install and repair Kohler products because they’re well made and parts stay available for a long time. We also work with KraftMaid cabinetry, Cambria and Silestone countertops, and Moen and Grohe fixtures when a remodel calls for them.
