AfterHow Much Does Tub-to-Shower Conversion Cost in Los Angeles?
A tub-to-shower conversion in Los Angeles typically costs $4,130 to $11,800 in 2026, with most standard 5×8-foot bathroom conversions landing between $6,500 and $9,000. The final number depends on your plumbing configuration, the materials you choose, and whether you’re pulling permits. This guide below breaks down exactly where the money goes, what drives the price up or down, and what you should expect from a contractor before you sign anything.
If you’re weighing a tub-to-shower conversion against a full bathroom remodel, our Tub-to-Shower Conversion in Los Angeles page covers the project scope in detail. And if you want to talk specific numbers for your bathroom, call Penhallow Remodeling Los Angeles at (213) 277-6578. Every estimate is written, line-itemed, and free.
Key Takeaways: Tub-to-Shower Conversion Cost in Los Angeles
- Typical range: $4,130 – $11,800, with mid-range conversions averaging $6,500 – $9,000.
- Labor accounts for 50 – 60% of the total: demo, plumbing rough-in, waterproofing, tile setting, finish work.
- Materials split into tiers: acrylic surround ($4,130 – $6,500), tile with prefab pan ($5,900 – $8,850), full custom tile ($7,100 – $11,800+).
- Plumbing relocation (moving the drain or valve) is the single biggest cost driver: $800 – $2,500 alone.
- Permits in Los Angeles add $400 – $1,200 depending on the scope and whether LA County or city jurisdiction applies.
- Every quote should be written. If a contractor won’t put the number in writing before demo day, you’re in for a surprise later.
Tub-to-Shower Conversion Cost Breakdown (2026)
Here’s a line-by-line look at what we see in the Los Angeles market right now. These are the numbers we quote, and we’re glad to walk you through any of them in person.
| Cost Component | Typical Range (Los Angeles, 2026) |
|---|---|
| Demolition of existing tub and surround | $425 – $950 |
| Plumbing modifications (valve, drain, supply lines) | $800 – $2,500 |
| Shower base/pan (acrylic or tile-ready prefab) | $500 – $1,400 |
| Wall surround or tile installation | $1,500 – $4,800 |
| Waterproofing (cement board substrate and membrane) | $300 – $900 |
| Glass shower door or curtain rod | $350 – $2,200 |
| Fixtures (shower valve, trim kit, showerhead) | $250 – $1,900 |
| Permit fees | $400 – $1,200 |
| Total Project Cost | $4,130 – $11,800 |
What drives a project toward the low end? A direct tub-to-shower swap where the drain stays put, the existing valve works, and you choose an acrylic or solid-surface surround. Los Angeles homes built after 2000 often fall into this category because the plumbing rough-in is still in good shape.
What drives it toward the high end? Moving the drain to center the shower footprint, replacing old galvanized supply lines, installing full ceramic or porcelain tile walls with a custom niche, and adding a frameless glass enclosure. In older LA neighborhoods like West Adams, Silver Lake, or the San Fernando Valley, we’re often cutting into concrete slab foundations or dealing with cast-iron drain lines that date to the 1950s. That work adds material and labor on the spot.
What Affects Tub-to-Shower Conversion Pricing in Los Angeles
- Plumbing location and condition. If you’re lucky, the existing tub drain can be reworked into a shower drain without moving the pipe. If not, you’re paying for concrete cutting or floor joist rework. In slab-on-grade homes common to the Valley, that cost is noticeably higher.
- Shower base type. An acrylic base runs $500 – $900 and installs fast. A tile-ready pan costs more upfront but allows the tile on the shower floor to match the walls. Custom mud-set tile pans in homes around Los Feliz or Hancock Park can push $2,000 alone.
- Finish materials. A Kohler or Moen valve and trim kit will cost more than a big-box brand, but they’re backed by manufacturer warranties that outlast the job. We install Kohler and Moen fixtures standard because the guarantee behind the product matters as much as the installation.
- Waterproofing method. Every conversion we do gets cement board substrate (the moisture-resistant layer behind your tile) and a surface-applied waterproofing membrane. Some contractors skip this step to cut cost. It’s not a place to save money, and we won’t do it.
- Permitting. Los Angeles requires plumbing permits for tub-to-shower conversions. If the work involves relocating the drain or moving valve lines, the inspection path is longer and fees climb. A legitimate contractor will line-item the permit. A contractor who says “you don’t need a permit for that” is giving you a reason to keep looking.
- Access to the bathroom. A second-story bathroom in a Pasadena craftsman or a hillside home in Mount Washington means more trips up stairs with tools and material. It’s not a huge line item, but it’s real labor.
Can You Convert a Tub to a Shower in a Day?
No, and anyone who promises you a one-day tub-to-shower conversion in Los Angeles is either doing something wrong or using language loosely. A straightforward conversion with an acrylic surround and no plumbing relocation runs 3 to 5 working days. A full tile shower with a relocated drain and cement board waterproofing takes 5 to 8 working days, plus 24 to 48 hours for materials like mortar and grout to cure between stages. Cutting those wait times short is how cracked grout and loose tile happen six weeks later.
How to Save on a Tub-to-Shower Conversion Without Cutting Corners
The first thing to understand: the cheapest bid in Los Angeles is rarely the least expensive by the time the job is done. That said, there are real ways to keep the number down.
- Keep the plumbing where it is. If you can live with a slightly offset drain location, you’ll avoid $800 to $2,500 in rework. Good contractors will tell you when moving the drain matters and when it doesn’t. Find one who does.
- Choose an acrylic or solid-surface surround. These install fast, clean up easily, and run $4,130 to $6,500 for a standard footprint. You give up the custom tile look but not the function or the warranty.
- Replace the valve even if it looks fine. A $300 valve replacement during a conversion is cheap insurance. Replacing it later means cutting into a finished wall. The valve is behind the wall for a reason; now is the time.
- Ask for a written, line-item quote. The fastest way to save money is to compare actual line items, not verbal ballparks. A contractor who hands you a number you can hold them to is telling you something about how they run the job. That’s the Kingswell Way standard we’ve operated under since 2004: the price goes in writing before any work starts, and the number on day one is the number on the invoice.

Is It Cheaper to Convert a Tub to a Shower or Replace a Tub?
Converting is almost always cheaper. A tub-to-shower conversion in Los Angeles runs $4,130 to $11,800 in 2026. Replacing a tub with a new tub and adding a new surround typically lands in the same zone, but you’re not gaining the accessibility and openness that most homeowners want. A full home remodel that moves walls or relocates the bathroom entirely is another tier up, comparable to a small bathroom remodel at $5,900 to $14,160. If the goal is an easier entry, a more open feel, and a lower maintenance surface, conversion wins on price and result.
Do You Need a Permit for a Tub-to-Shower Conversion in Los Angeles?
Yes. The City of Los Angeles Department of Building and Safety requires a plumbing permit for any tub-to-shower conversion that touches the drain, valve, or supply lines. In unincorporated LA County areas, County Public Works governs the same scope. A legitimate contractor pulls the permit, schedules the inspection, and stands behind the work. A contractor who tells you permits are optional is either misinformed or risking your remodel passing future inspection when you sell. If you’re selling the house, unpermitted work is a liability that shows up at the worst possible time. We pull permits on every conversion, and the permit fee is always a line item on your written quote, never buried and never “handled later.”
What’s Included in a Quality Tub-to-Shower Conversion?
Here’s what you should see on any legitimate proposal for a Los Angeles tub-to-shower conversion. If any of these items are missing, ask why.
- Written price before any work starts. Not a range, not a ballpark. A written number you can hold the contractor to. At Penhallow, that’s the only way we do it.
- Demo, removal, and haul-away of the existing tub, surround, and any affected drywall.
- Plumbing evaluation and modification with a written description of exactly what’s being moved, replaced, or retained.
- Waterproofing assembly – cement board substrate and a surface membrane behind all tile surfaces.
- The shower base, wall surround, fixtures, and finish trim specified by brand and model, not “contractor grade.”
- Permit fees and inspection scheduling.
- A written guarantee covering the workmanship. We put a 365-Day Done Right Promise on every project: if something fails inside that year, we come back and fix it without a service call or re-inspection fee. That promise is in writing, on the quote, before we start.
FAQs – Tub-to-Shower Conversion Cost in Los Angeles
How much does a tub-to-shower conversion cost in Los Angeles?
A tub-to-shower conversion in Los Angeles costs $4,130 to $11,800 in 2026, depending on plumbing scope, material choices, and whether you’re in a slab-on-grade Valley home or a raised-foundation property in the central city. Most standard conversions land between $6,500 and $9,000. Call (213) 277-6578 for a written, line-itemed quote on your specific bathroom.
How long does a tub-to-shower conversion take?
A standard conversion runs 3 to 8 working days, depending on whether the plumbing stays put and the wall finish is acrylic or full tile. Acrylic surround conversions with no drain relocation finish in about 3 to 5 days; full tile with plumbing modifications takes 5 to 8 days plus curing time. We give you a written schedule when we hand you the quote.
Can you convert a tub to a shower the same day?
No honest contractor should promise a one-day tub-to-shower conversion in Los Angeles. The fastest legitimate timeline is roughly 3 working days. Mortar, grout, and waterproofing membrane all need cure time between stages. When someone promises same-day, the materials aren’t curing, and that’s a guarantee of problems later. We’d rather do it at the pace that makes the work last.
Is a tub-to-shower conversion worth the cost?
For most Los Angeles homeowners, yes. At $4,130 – $11,800, a tub-to-shower conversion is among the lower-cost ways to meaningfully change how a bathroom feels and functions. It improves daily use, reduces maintenance, and ages well for resale. The alternative – living with a tub you’re not using – costs nothing but the daily annoyance. If the tub is becoming a step-over hazard, the conversation changes entirely.
Why is tub-to-shower conversion so expensive in Los Angeles?
Los Angeles has real permitting costs, higher labor rates than most metro areas, and a housing stock that includes everything from slab-on-grade 1950s ramblers in the Valley to century-old raised-foundation homes in Highland Park. Add in waterproofing requirements that some markets skip, and the result is a fair market range of $4,130 – $11,800. The work is the same anywhere; the local conditions are what set the number. Call (213) 277-6578 and we’ll tell you where your house falls before you spend another minute guessing.
Why the Written Number Matters More Than the Lowest One
Trevor Nash started Penhallow Remodeling Los Angeles because he kept meeting homeowners who’d been burned by verbal estimates that ballooned at the door. And that’s exactly who we built this company for: the person who’s already had a contractor not show up, or a price that changed after demo day, or a repair that cracked six weeks later. You’re not looking for the cheapest bid. You’re looking for a company that answers, arrives when it said it would, and stands behind the work after the crew leaves.
That’s what the Kingswell Guarantee is: a written price before any work starts, a defined arrival window, a clean job site, and a written guarantee on every project. We’ve run this way since 2004.
