AfterHow Much Does Tub-to-Shower Conversion Cost in Los Angeles?
Tub-to-shower conversion in Los Angeles typically costs between $4,130 and $11,800, with most single-bath projects landing near $6,800 to $8,500 once tile, fixtures, and waterproofing are included. That range reflects the L.A. market as of 2026: higher labor rates than most of the country, older plumbing common in pre-1960 homes, and frequent surprises behind the wall once a tub comes out. A written price comes before any work starts, so you’ll know your number before demolition day.
If you’re converting a standard 5-foot tub alcove in a house built before 1970, expect to be closer to the top of that range. A straightforward swap in a newer home with accessible plumbing often lands near the bottom. For the full scope of what this project involves, see our Tub-to-Shower Conversion in Los Angeles service page.
Key Takeaways
- Most Los Angeles tub-to-shower conversions cost $4,130 to $11,800, with a typical mid-range project around $7,000.
- The biggest cost drivers are tile choice, fixture brand, and what we find behind the tub surround.
- Older homes with galvanized or cast-iron drains can add $800 to $2,500 in plumbing updates.
- A written price is delivered before any work begins, on every project, and it doesn’t change because we found dry rot. That’s quoted into the estimate upfront.
- Every conversion is covered by our 365-Day Done Right Promise: if something isn’t right within a year of completion, we make it right at no cost.
Tub-to-Shower Conversion Cost Breakdown (2026)
Here’s how the numbers usually shake out on a Los Angeles conversion. These are real dollar ranges for labor and materials combined, not vague estimates.
| Line Item | Typical Range | What It Covers |
|---|---|---|
| Demolition & haul-away | $350 – $950 | Removing the tub, surround, and old valve; disposing of debris |
| Plumbing rough-in | $600 – $2,500 | Relocating the drain, new mixing valve, updating supply lines |
| Waterproofing & backer board | $550 – $1,400 | Cement board, waterproof membrane, sealing seams and corners |
| Tile & installation | $1,200 – $4,200 | Wall and floor tile, setting materials, grout, Schluter strip (the metal trim that seals the edge where tile meets flooring) |
| Shower pan or base | $400 – $1,600 | Pre-formed acrylic base or custom-tiled pan with liner |
| Shower valve & trim | $300 – $1,100 | Pressure-balance or thermostatic valve, handle, escutcheon |
| Showerhead & controls | $150 – $750 | Fixed head, handheld, or rain combination |
| Glass door or enclosure | $500 – $2,400 | Framed or frameless door, panel, hardware |
| Grab bars & safety hardware | $120 – $600 | ADA-compliant bars, bench, or seat |
| Permits & inspection | $150 – $600 | L.A. Department of Building and Safety permit fees where required |
| Finish work & paint | $250 – $900 | Drywall patching, caulk, paint, hardware install |
Total for a standard alcove conversion: $4,130 to $11,800, with most homeowners landing near $6,800. That figure tracks with the broader bathroom remodel cost in Los Angeles, which runs $10,620 to $33,040 when you’re redoing the entire room rather than just the tub area.
What pushes a project to the high end? Full custom tile work with a mosaic feature wall, a frameless glass door, a thermostatic valve with multiple outlets, and a bench. What keeps it near the bottom? A prefab acrylic base, standard 12×24 tile, a single pressure-balance valve, and a framed glass door.
What Affects Tub-to-Shower Conversion Pricing in Los Angeles
- Age and condition of your plumbing. In Silver Lake and Echo Park, homes built in the 1920s and 30s often still have galvanized supply lines. They work fine until they don’t. Replacing them during conversion adds $800 to $2,500, but doing it now saves you from tearing out new tile in two years.
- What’s behind the tub surround. Until we pull the old surround, nobody knows whether there’s dry rot, mold, or a previous contractor’s shortcut. We quote a contingency line into every written price so surprises don’t become change orders.
- Tile selection. Standard porcelain runs $4 to $8 per square foot. Natural stone, large-format slabs, or hand-made tile can run $15 to $40 per square foot, and labor goes up because cuts are harder and waste is higher.
- Shower base vs. custom pan. A prefab acrylic base is fast and cheap. A custom-tiled pan with a proper sloped liner takes an extra day and adds $600 to $1,200, but it’s what you want if you’re matching flooring or going for a seamless look.
- Glass enclosure vs. curtain rod. A basic framed door is around $500. A frameless 3/8-inch glass enclosure with premium hardware runs $1,500 to $2,400. The glass is often the single most noticeable upgrade in the room.
- Permits and inspections. Converting a tub to a shower often requires a plumbing permit in the City of Los Angeles, especially when the drain is relocated. Permit fees run $150 to $600 depending on valuation, and an inspection adds a day to the schedule.
- Access and parking. In dense neighborhoods like Koreatown or West Hollywood, a dumpster permit and street parking for the crew add cost. In the Valley, it’s usually a non-issue.
Why Los Angeles Pricing Runs Higher Than National Averages
The national average for a tub-to-shower conversion sits around $3,000 to $8,000. Los Angeles runs $4,130 to $11,800 for a few specific reasons that aren’t going away.
First, labor. A licensed tile setter in L.A. County charges $85 to $140 per hour, and a journeyman plumber runs $110 to $180 per hour. Those rates reflect the cost of living, the permitting environment, and the demand from a metro area where there’s always another project waiting.
Second, code. California’s Title 24 energy code and the state’s plumbing code are stricter than most. A shower valve has to be pressure-balance or thermostatic. The pan has to be sloped a minimum of 1/4 inch per foot. Waterproofing has to meet ANSI standards. Those requirements add material and labor that cheaper markets skip.
Third, housing stock. Los Angeles has more pre-war homes than most major cities. According to census data, roughly 40% of the city’s housing units were built before 1960. Those homes have original plumbing, original framing, and often original problems. The work is real, and the price reflects it.
We’ve been doing this since 2004 as part of the Threshold Group family of home-service companies. We’ve seen what’s behind a 1940s tub in Highland Park and what’s behind a 1990s tub in Sherman Oaks. The difference is significant, and we price accordingly with a written number before we touch a thing.
How to Save on Tub-to-Shower Conversion
You can bring the number down without sacrificing quality. Here’s what actually works.
- Keep the drain where it is. Relocating the drain means cutting into the slab or subfloor, rerouting the trap, and patching. If you can live with the shower drain in the same spot as the tub drain, you save $600 to $1,800.
- Choose porcelain over natural stone. Porcelain looks like stone now. It’s easier to maintain, less expensive, and for a shower wall, honestly, it holds up better to daily use. Save the stone for a feature strip or a niche.
- Skip the custom pan if the floor is sound. A well-installed acrylic base is durable, easy to clean, and saves $600 to $1,200. If you have a specific design in mind, custom makes sense. If not, the prefab option is a smart call.
- Bundle with other bathroom work. If you’re also replacing the vanity, toilet, or flooring, doing it all in one project saves on mobilization, permits, and demolition. Our Bathroom Remodel in Los Angeles guide walks through how that pencils out.
- Get three quotes, but compare scope. The lowest bid usually isn’t the lowest cost. If one quote excludes waterproofing or permits, you’re not comparing apples to apples.
- Ask about material partnerships. We work with specification-grade brands – Kohler, Moen, Toto, Grohe for fixtures – which means access to vetted products at professional pricing, not big-box markups.

What to Watch For Behind the Tub
This is the part most homeowners don’t think about until the tub is out. In Los Angeles, we see a few consistent issues.
Dry rot in the framing. Bathrooms in older homes often have a slow leak that’s been dripping behind the wall for years. The wood softens, and when we pull the surround, it crumbles. Rebuilding the framing adds $400 to $1,200.
Improper waterproofing from a previous remodel. We’ve opened up showers with nothing but green drywall behind the tile. No membrane, no cement board, just a future mold problem. We replace it. There’s no shortcut here.
Undersized or corroded drain lines. A 1.5-inch drain was standard for tubs. Showers need 2-inch. If you’re pulling a permit, that upgrade is usually required. It’s also the right thing to do, because a shower flows more water than a tub and a narrow drain clogs faster.
Electrical code issues. If there’s a light fixture inside the shower zone or an outlet too close to the water source, that has to be corrected before the final inspection. We flag it during the estimate, not after.
FAQs – Tub-to-Shower Conversion Cost
How much does a tub-to-shower conversion cost in Los Angeles?
Most conversions cost between $4,130 and $11,800, with a typical mid-range project around $6,800. That includes demolition, plumbing, waterproofing, tile, a new shower valve, a base or pan, and a glass door. Custom tile, frameless glass, and updated plumbing push the number higher. Call (803) 680-2547 for an exact quote – estimates are free.
Is it cheaper to convert a tub to a shower or replace the tub?
Replacing a tub with a new tub typically costs $1,500 to $4,500, which is less than a conversion. But if you’re not using the tub, a conversion adds usable space, improves accessibility, and often increases resale appeal in the L.A. market. The question isn’t just cost; it’s how you’ll use the bathroom for the next 10 years. Call (803) 680-2547 to talk through both options with a written price for each.
How long does a tub-to-shower conversion take in Los Angeles?
A standard conversion takes 5 to 10 working days on site, plus permit processing time if a permit is required. Custom tile work, a relocated drain, or unexpected framing repairs can stretch that to 2 or 3 weeks. We give you a realistic schedule in the written estimate, not a best-case number. Call (803) 680-2547 to schedule your walkthrough.
Do I need a permit for a tub-to-shower conversion in Los Angeles?
If you’re moving the drain, changing the valve, or altering the plumbing, yes – the City of Los Angeles requires a plumbing permit, and sometimes an electrical permit if lighting is involved. Permit fees run $150 to $600. We handle the paperwork and inspections as part of the project. Call (803) 680-2547 and we’ll tell you exactly what your address requires.
What’s the best shower base for a Los Angeles conversion?
For most homes, a prefab acrylic base is the practical choice – it’s durable, easy to clean, and costs $400 to $1,600 installed. If you want a seamless tile floor that matches your walls, a custom-tiled pan with a proper liner runs $1,000 to $2,200 and looks exceptional when done right. Either way, the pan has to be sloped and waterproofed to code. Call (803) 680-2547 for a recommendation based on your bathroom layout.
