AfterHow Much Does Tub-to-Shower Conversion Cost in San Antonio?
A tub-to-shower conversion in San Antonio typically costs $3,500 to $10,000 in 2026, with most mid-size replacements landing between $5,500 and $7,500. The spread comes down to the shower base you choose, whether walls need re-plumbing, and how much tile or surround work is involved. We’ll break down exactly where the money goes below so you can price your job before you ever pick up the phone.
Tub-to-Shower Conversion Cost Breakdown (2026)
Here’s a line-by-line look at what a San Antonio tub-to-shower conversion actually costs. These are real 2026 numbers from our local job sheets, not national averages.
| Line Item | Low End | High End | What You’re Paying For |
|---|---|---|---|
| Demo & haul-away | $500 | $1,200 | Removing the old tub, cutting out damaged subfloor if needed, disposal fees |
| Shower base / pan | $400 | $1,800 | Acrylic at the low end; custom tile-ready mortar pan at the high end |
| Wall surround or tile | $800 | $3,500 | Acrylic/fiberglass panels vs. full tile with waterproofing membrane |
| Plumbing modifications | $600 | $2,000 | Moving the drain to center, raising the showerhead supply line, new mixing valve |
| Glass door or curtain rod | $150 | $1,200 | Rod + curtain at the low end; frameless glass door and panel at the high end |
| Fixtures (valve, head, trim) | $200 | $900 | Builder-grade Moen to Kohler or Grohe trim kits |
| Finishing & trim work | $300 | $800 | Caulking, baseboard, drywall repair, paint touch-up |
| Permits (City of San Antonio) | $150 | $400 | Required when moving plumbing; drawn by the scope of the job |
What moves the needle most? Two things: your wall finish (tile vs. acrylic surround) and whether the existing drain location works for a shower. In San Antonio’s older neighborhoods, like Alamo Heights, Monte Vista, and Jefferson, we routinely open walls and find cast-iron drain lines from the 1950s that need adaptation or replacement. Budget an extra $800 to $1,500 if your home falls in that era.
What Affects Tub-to-Shower Conversion Pricing in San Antonio
- Drain relocation. Most tubs have a drain at one end. Showers need it centered. Moving a drain means cutting into the slab foundation, which runs $800 to $2,000 depending on how far it has to travel. On pier-and-beam homes in Olmos Park or Terrell Hills, it’s easier and cheaper because there’s crawl space access.
- Slab vs. pier-and-beam foundation. San Antonio sits on limestone and expansive clay soil, and most homes here are slab-on-grade. Cutting through concrete to move plumbing is a bigger job than working from below. This single factor can swing the price by $1,000 or more.
- Waterproofing method. We use full waterproofing membranes behind tile (Kerdi or similar), not green board. It costs $400 to $900 more than the cheap route, and it’s the difference between a shower that lasts 5 years and one that lasts 30. San Antonio’s humidity makes this non-negotiable.
- Existing water damage. If the old tub surround leaked, you’ll find rotted studs and subfloor behind it. Repairs run $300 to $1,200 depending on how far the rot spread.
- Finish material choices. Basic white acrylic surrounds keep you near the low end. Porcelain tile, custom niches, benches, and frameless glass push you past $8,000 fast.
- Permit status. The City of San Antonio requires a permit when plumbing lines move. It’s a few hundred dollars and it protects you when you sell. Skipping it saves money now and creates a problem at resale.
Is a Tub-to-Shower Conversion Worth It in San Antonio?
For most San Antonio homeowners, the answer is yes. A walk-in shower makes the bathroom safer and easier to use, especially in aging-in-place situations, and it’s one of the higher-return bathroom upgrades you can make. Buyers in San Antonio increasingly expect a walk-in shower in the primary bath, particularly in newer northside developments around Stone Oak, Alamo Ranch, and the Dominion.
One local factor worth knowing: many San Antonio homes from the 1970s through the 1990s were built with a single full bath containing a tub/shower combo. If that’s your only bathtub, converting it means the house has no tub at all. That matters for resale if the next buyer has young children. Our team talks through this trade-off on every estimate, because the right answer depends on your house, not on what’s popular.
Tub-to-Shower Conversion vs. Replacement: What’s the Difference in Cost?
A tub-to-shower conversion runs $3,500 to $10,000. A like-for-like tub replacement (pulling the old tub, dropping in a new one) runs $2,000 to $5,000. The conversion costs more because you’re changing the plumbing layout, the footprint, and usually the wall finish. It’s a bigger scope of work, and the price reflects it.
If you’re weighing the two, the question usually comes down to how you actually use the bathroom. If nobody in the house takes a bath, converting to a shower is the better long-term play. If you need to keep a tub for kids or resale, a tub replacement is the lower-cost option.
How Long Does a Tub-to-Shower Conversion Take in San Antonio?
Plan on 3 to 7 working days for a standard conversion. Demo day is one. Plumbing and waterproofing take the next one to two. Tile work runs two to three days if you’re going that route. Glass installation happens after everything else is cured and measured, usually a week later.
Permit timing in San Antonio adds a few days on the front end. The city’s Development Services Department typically processes simple plumbing permits in 3 to 5 business days. We pull permits as part of the job, so you don’t have to deal with that process yourself.
How to Save on Tub-to-Shower Conversion
You can cut real money off a conversion without cutting corners. Here’s what works and what doesn’t.
- Keep the drain where it is when you can. If the tub drain is close enough to the new shower footprint to work, leaving it put saves the biggest single line item on the job: slab work. We’ll tell you honestly whether it’s possible.
- Choose an acrylic surround over tile. Acrylic runs $800 to $1,800 installed, versus $2,000 to $3,500 for full tile. It’s faster, cheaper, and easier to clean. You lose the custom look, but you keep $1,500 or more in your pocket.
- Skip the frameless glass. A shower curtain and rod cost under $200. A frameless glass door and panel run $900 to $1,200. That’s a thousand-dollar decision you can defer.
- Do the finish work in phases. If budget is tight, get the waterproofing, plumbing, and surround done now. Add the fancy niche, bench, or glass down the road. The core shower is what matters.
- Ask for an itemized written quote. If a contractor won’t put the price in writing before work starts, the price will change. We give a written line-item price before any tool gets picked up, on every single job. That’s the Relay Standard, and it’s not an upgrade.

FAQs – Tub-to-Shower Conversion Cost
How much does it cost to convert a tub to a walk-in shower in San Antonio?
Most San Antonio tub-to-shower conversions run $3,500 to $10,000, with the typical mid-range job landing around $5,500 to $7,500. The biggest variables are your wall finish, whether the drain needs to move, and what kind of glass or curtain enclosure you choose. Give us a call at (432) 547-6806 for a free written estimate.
Does a tub-to-shower conversion add value to a home in San Antonio?
Yes, typically. A well-done walk-in shower adds functional value and broadens appeal for most buyers. The return is stronger in the primary bath and weaker if it leaves the house with zero bathtubs. We’ll tell you straight which situation applies to your house before any work is scheduled.
Can you convert a tub to a shower in one day?
No. Acrylic liner companies advertise one-day jobs, and those are acrylic liners installed over the existing tub, which is a different thing. A true tub-to-shower conversion, where the tub comes out and the footprint changes, takes 3 to 7 working days including waterproofing, tile or surround work, and finish trim. Anything that promises one day is either not a real conversion or is skipping steps you’ll pay for later.
What’s the cheapest tub-to-shower conversion option?
The lowest-cost legitimate conversion is an acrylic shower base with an acrylic surround, without moving the drain and using a curtain instead of glass. That lands around $3,500 to $4,500. It’s a clean, functional, durable setup. You sacrifice tile and custom details, not quality.
Is it cheaper to convert a tub to a shower or replace the tub?
A tub replacement is cheaper, running $2,000 to $5,000 versus $3,500 to $10,000 for a conversion. The conversion costs more because it involves changing the plumbing layout, waterproofing a new footprint, and typically upgrading the wall finish. If you’re trying to keep costs down and still need a tub, replacement is the lower-cost move.
Do I need a permit for a tub-to-shower conversion in San Antonio?
Yes, when plumbing moves. The City of San Antonio requires a permit for relocating or modifying drain lines. Permit costs run $150 to $400 and are typically included in your contractor’s price. We handle the permit process as part of every conversion, so you don’t have to visit the city’s Development Services office yourself.
