AfterHow Much Does Tub-to-Shower Conversion Cost in Orange County?
A tub-to-shower conversion in Orange County typically costs between $3,500 and $10,000 in 2026, with most mid-range jobs landing around $6,500 to $7,500. That price includes demolition, plumbing, waterproofing, tile or acrylic surround, a new shower pan, valve, and fixture. At the low end you’re getting a stock acrylic surround with a basic valve; at the top of that range you’re looking at custom tile work, a bench, niches, frameless glass, and upgraded fixtures from manufacturers like Kohler or Moen.
These numbers reflect what we see across Orange County: Anaheim, Santa Ana, Irvine, Huntington Beach, Fullerton, Costa Mesa, Mission Viejo, and everywhere in between. Permits, which we’ll get into below, add a separate layer you should know about before you sign anything.
If you’re comparing quotes, make sure the number you’re comparing is the written number. More on that throughout this guide. If you want a specific number for your bathroom, call us at (424) 541-1701 and we’ll look at your space, your existing plumbing, and your finish preferences, then put a price in writing before any work starts.

Key Takeaways
- Orange County range: $3,500 to $10,000, with most conversions landing between $6,000 and $8,000.
- Acrylic surrounds are the biggest cost lever: they can cut $2,000 to $4,000 off the price versus custom tile.
- Moving the drain or valve adds $800 to $2,500 depending on your slab or raised foundation.
- Permits in Orange County cities typically run $150 to $500 and are required for any plumbing change.
- Glass doors are usually quoted separately: budget $700 to $2,200 for a frameless door depending on width.
- Time frame: most jobs finish in 3 to 7 working days. Tile work extends that.
- You should never accept a verbal estimate on this work. Demand a written price before demo day.
Tub-to-Shower Conversion Cost Breakdown (2026)
Here is the line-item breakdown we use when we write a tub-to-shower conversion quote in Orange County. These are real ranges based on what materials and labor cost in this market right now, not national averages that don’t line up with what you’ll actually pay here. Note that these numbers assume your bathroom is in reasonable condition: no hidden water damage, no re-piping needed, nothing structural.
| Line Item | Typical Orange County Range | What It Covers |
|---|---|---|
| Demolition and disposal | $400 – $900 | Removing the old tub, wall surround, and any soggy drywall or greenboard behind it. Hauling to a legal disposal facility. Dump fees in OC run higher than the Inland Empire. |
| Plumbing modification | $500 – $2,000 | Converting the tub drain (1-1/2”) to a shower drain (2”), repositioning the valve, raising the showerhead. The bigger jump happens if you’re moving the drain location. |
| Shower pan | $500 – $1,200 | Either a pre-formed acrylic pan (less expensive, faster) or a mortar bed with waterproofing for tile (more expensive, better for custom layouts). |
| Walls: acrylic surround or tile | $1,000 – $4,500 | Stock acrylic panels run $1,000 to $2,200 installed. Custom tile with cement board substrate (the moisture-resistant layer behind your tile) and waterproofing membrane runs $2,500 to $4,500. |
| Shower valve and trim | $250 – $900 | Pressure-balanced or thermostatic valve plus the visible trim. Moen and Kohler both make durable options. A thermostatic valve, which keeps temperature steady when someone flushes a toilet, costs more. |
| Showerhead and arm | $80 – $400 | Standard fixed head up to a rain head and handheld combo. The plumbing rough-in matters: if you want a rain head, the pipe has to be run before the tile goes up. |
| Glass door or curtain rod | $700 – $2,200 | A curtain rod is $50 and we’ll be honest: lots of Orange County homeowners start with a curtain and add glass later. A frameless glass door is the number most people want. Width drives the price. |
| Permits and inspection | $150 – $500 | Every city in OC has its own fee schedule. Anaheim charges differently than Irvine charges differently than Fountain Valley. The permit protects you: it means a city inspector verifies the waterproofing before it’s covered up. |
| Drywall patching and paint | $200 – $700 | Where the old tub surround met drywall, plus any damage from removal. |
| Total | $3,500 – $10,000 |
Two things push that total up faster than anything else in Orange County. The first is moving the drain. Your existing tub drain is against the wall end; a shower drain sits more toward the center of the footprint. On a slab foundation, moving it means cutting concrete, and that’s where the extra $1,000 to $2,500 shows up. On a raised foundation with a crawlspace, it’s easier and less expensive.
The second is water damage you can’t see until the tub comes out. Orange County homes built between the 1960s and early 2000s frequently used sheetrock behind tub surrounds instead of cement board. If water has been seeping through grout or caulk for years, we find rotted studs or subfloor. That’s a legitimate change-order item, and a good contractor will photograph it and show you exactly what they found before charging a dollar more. A bad one will just send an invoice.
If you’re comparing our page to other contractors’ sites, note that some Orange County remodelers quote “starting at $5,000” and that number doesn’t include the pan, valve, or door. Always ask: what exactly is in the written price? We’re a home remodeling company, and we write the full scope on paper before we start. No verbal caveats.

What Affects Tub-to-Shower Conversion Pricing in Orange County
- The age of your house. Homes built before 1990 in Orange County often have cast iron drain lines and tile set over a thick mortar bed instead of drywall. Demolition takes longer, disposal costs more, and sometimes the old cast iron needs a section replaced. Homes built after 2000 usually come apart cleanly and cost less to convert.
- Slab versus raised foundation. This is the one that moves the price the most, and it’s specific to Southern California construction. Most OC homes built in the 1950s through 1970s are slab-on-grade. Moving that drain means saw-cutting concrete. In coastal communities like Huntington Beach and Newport Beach, you’ll find raised floors on some older beach cottages, which makes plumbing work simpler and cheaper.
- City permit fees and inspection schedules. We pull permits for tub-to-shower conversions, which means going through each city’s building department. Santa Ana, Garden Grove, and Orange all have different fee structures and wait times for inspections. That affects both the cost of the permit and how long the job takes.
- Material finish level. A stock acrylic surround in white or biscuit is the lowest-cost option and it’s genuinely fine: it’s what we’d recommend for a rental or a guest bath. If you’re doing your primary bath, most Orange County homeowners want porcelain or ceramic tile with a glass door, which adds $2,000 to $4,500.
- Access. If your bathroom is on the second floor of a home in Irvine or Lake Forest and the tub needs to come out in pieces, that takes longer. If there’s a long path from the driveway to the bathroom through finished hallways, the crew is spending time protecting floors and carrying materials in and out.
- Waterproofing method. There are two legitimate ways to waterproof a shower: a traditional built-up membrane (older method, still fine if done carefully) and a modern bonded waterproofing system applied directly under tile like Schluter Kerdi or Laticrete Hydro Ban. The modern methods cost a bit more in materials but we use them because they fail less often. Ask any contractor exactly what waterproofing system they use, and get it in writing.
Is It Cheaper to Repair Your Tub or Convert It?
A tub repair in Orange County, whether it’s reglazing, replacing a cracked section, or fixing a leaking drain, typically runs $100 to $800. A conversion is $3,500 to $10,000. So yes, repair is substantially less expensive, at least on day one.
But the honest answer depends on what’s actually wrong. If your tub is in good shape and you just want a shower instead, and you’re planning to stay in the house, converting makes sense. A converted shower is also a selling point in Orange County: buyers see a walk-in shower as a feature, not a compromise. If your tub is cracked and old and the surround is failing, putting $800 into reglazing is postponing the problem, not solving it. The grout will still leak, the caulk will still split, and you’ll be back here in two years.
Here’s a practical way to think about it. If you’re staying less than three years and the tub is functional, repair it or leave it alone. If you’re staying longer, or the tub is failing, convert it. Call (424) 541-1701 and we’ll come look at what you’ve got. We’ll tell you if conversion is the right call, and we won’t sell you a job you don’t need.
How to Save on Tub-to-Shower Conversion
You can save real money on a tub-to-shower conversion without cutting corners that matter. Here’s what actually moves the number.
- Keep the plumbing where it is. Use a shower pan designed to work with a drain in the same location as your old tub drain if the layout allows. You’ll save the cost of concrete cutting and re-routing.
- Choose a stock acrylic surround. It’s not marble, and it’s not trying to be. It’s low-maintenance, easy to clean, and it installs in one day instead of three. For a guest bath or a kid’s bath, it’s the sensible money move.
- Buy a standard frameless door, not a custom one. Standard widths (48″, 54″, 60″) cost less because no one has to custom-fabricate the glass. If your opening happens to land on a stock size, you’ll save $300 to $600.
- Do the paint and trim yourself. If the scope only touches the shower and you’re comfortable painting, that takes a few hundred dollars off the invoice.
- Bundle it with another project. If you’re already doing a Tub-to-Shower Conversion in Orange County and you’ve been thinking about updating the vanity too, doing them at the same time saves on mobilization, permits, and schedule coordination.
- Time it with realistic scheduling. Some Orange County homeowners ask us to wait a week or two if we’re already booked, and that doesn’t change the price, but being flexible on the date means we can often slot the project between larger jobs, keeping your costs down because the crew is already in the area.
One thing not to do: install the shower yourself. We’re not going to tell you that you can’t, but faucet and drain plumbing inside a wall, waterproofing without a vapor barrier gap, and building code compliance for the shower valve are where well-intentioned DIY projects go wrong. A leak behind a shower wall you can’t see will do tens of thousands in damage before you know it’s there. The cheapest option that still gets you a shower that won’t leak behind the wall is a professionally installed acrylic surround with a stock pan and standard trim. That’s where the $3,500 number comes from.
How Long Does a Tub-to-Shower Conversion Take in Orange County?
Most tub-to-shower conversions take 3 to 7 working days. An acrylic surround job with no plumbing relocation usually finishes in 3 to 4 days, including demolition, rough-in, pan, surround, trim, and a final walkthrough with you. Tile work extends the schedule because each stage has to set before the next begins: waterproofing cures overnight, tile sets overnight, grout sets overnight.
Permits and inspections add typically 1 to 3 working days total, depending on the city. In Irvine and Mission Viejo, inspectors usually show up within 48 hours of our request. In older, denser cities like Santa Ana and Garden Grove, it can stretch a bit longer. We’ll tell you the schedule before we start, based on your city, and we’ll give you a written arrival window, not a “sometime next week.”
Do You Need a Permit for a Tub-to-Shower Conversion in Orange County?
Yes. If we’re changing the shower valve, moving or replacing the drain, or altering any plumbing behind a wall, a permit is legally required in every Orange County city. That includes Anaheim, Santa Ana, Irvine, Huntington Beach, Fullerton, Costa Mesa, Orange, Tustin, Mission Viejo, and all the smaller incorporated cities in between.
We pull the permit as part of the job. An inspector comes out and verifies that the valve is installed to code, the drain is sized and sloped correctly, and the waterproofing is in place before it’s covered. That inspection protects you from buying someone else’s bad work. If a contractor tells you a permit isn’t needed for this project, call someone else. They’re either wrong or trying to avoid the inspection, and both of those are problems you don’t want to own.
What the 365-Day Done Right Promise Means for Your Conversion
Here’s the part of this page where we explain exactly what our guarantee covers, because “we stand behind our work” doesn’t mean anything unless it’s written down. Our standard on every tub-to-shower conversion in Orange County is the 365-Day Done Right Promise. Here’s what that means in plain words:
- You get a written price before any work starts. Not an estimate range. Not a ballpark. A line-item number on paper. The number on day one is the number on the invoice, unless you change the scope or we find hidden damage, and if we find hidden damage, we stop and show you before we do anything else.
- You get a written guarantee on the work. It’s included with every conversion. No extra charge, no fine print about exclusions that quietly erase the whole thing.
- If something we installed fails within 365 days, we come back and fix it at no charge. No service call fee, no diagnostic fee, no re-inspection fee. We make it right.
- If a repair we performed fails and needs a return visit, that visit is free too. This is part of the Kingswell standard we’ve operated under since 2004: say the price before the work, show up in the window we gave, leave the place cleaner than we found it.
That’s The Kingswell Way. It’s not a marketing phrase. It’s how we run every job, and it’s why we put the promise in writing on every project. If you’re getting quotes from other Orange County remodelers and the guarantee is vague, ask them: what exactly happens if it fails? What does the guarantee cover? How long? What does it cost to have you come back? If the answer fades into “oh, we take care of our customers,” then you have your answer.
How We Price a Tub-to-Shower Conversion
Here’s how our quotes come together. This isn’t proprietary trade knowledge; it’s how any straightforward contractor should be explaining a price. We walk your bathroom, measure the opening, look at the existing plumbing configuration, check the foundation type, and ask about your finish preferences. Then we build the price from the line items in the table above, add the permit fee for your specific city, and write it down for you.
If you want cabinet or vanity work done at the same time, we can include those lines in the same quote. We install cabinet lines from KraftMaid and Wellborn, and fixtures from Kohler, Moen, and Delta. The product brands behind the work matter: a Kohler valve carries a limited lifetime warranty that exists independently of our workmanship guarantee. That’s two layers of protection on the same faucet.
Penhallow Remodeling Orange County is independently owned and operated as part of the Kingswell family of companies. Led by Trevor Nash, we serve homeowners across Orange County with the same written-price, written-guarantee standard on every project. Our technicians are background-checked and arrive in uniform, so you know exactly who’s walking into your home. A live person answers the phone 24/7. That’s not a department. It’s just how we answer.
FAQs – Tub-to-Shower Conversion Cost
How much is a tub-to-shower conversion in Orange County in 2026?
A tub-to-shower conversion in Orange County costs $3,500 to $10,000, with the average project landing around $6,500. An acrylic surround with a stock pan and a basic valve is the least expensive option, and custom tile with a frameless glass door and a relocated drain pushes the price toward the top of the range. Call (424) 541-1701 for a written, itemized quote for your specific bathroom.
Is it cheaper to convert a tub to a shower or install a walk-in shower from scratch?
Converting an existing tub to a shower is usually cheaper than building a walk-in shower where one doesn’t exist, because the plumbing stub and drain are already in the room. You’re typically looking at $3,500 to $10,000 for a conversion versus $4,500 to $12,000 for a new walk-in shower with the same finishes. The difference is the framing, waterproofing, and plumbing work required when no existing wet area is in place.
Can a tub-to-shower conversion be done in one day?
No. Even a straightforward acrylic surround conversion takes 3 to 4 working days, because waterproofing, plumbing inspection, and pan installation cannot be skipped or rushed. Tile conversions take 5 to 7 working days. Any contractor who says they’ll do a code-compliant tub-to-shower conversion in one day is skipping something. Call (424) 541-1701 and we’ll give you a realistic schedule in writing.
What’s the most expensive part of a tub-to-shower conversion?
The two biggest cost drivers are moving the drain ($800 to $2,500 on a slab foundation, less on a raised foundation) and custom tile work ($2,500 to $4,500 for the walls). If you keep the drain where it is and go with a stock acrylic surround, you’ll stay on the low end of the $3,500 to $10,000 Orange County range.
Do tub-to-shower conversions add value to a home in Orange County?
Yes. In the Orange County real estate market, walk-in showers are consistently more desirable to buyers than old tub-shower combos. Home buyers in Orange County associate a converted walk-in shower with accessibility and modern design, and removing an aging tub eliminates a common inspection objection. For a homeowner who plans to stay, the value is also functional: easier entry, more usable floor space, and a shower that actually works the way you want it to. Call (424) 541-1701 for a free estimate and we’ll help you figure out what’s right for your home.
