AfterHow Much Does Tub-to-Shower Conversion Cost in West Covina?
A tub-to-shower conversion in West Covina typically runs $3,500 to $10,000, with most homeowners landing between $5,500 and $8,000 for a standard 60-inch alcove conversion using mid-range materials. The final number depends on whether you’re doing a basic swap, adding custom tile work, relocating plumbing, or addressing water damage discovered during demo.
Tub-to-Shower Conversion Cost Breakdown (2026)
Here’s what a typical West Covina tub-to-shower conversion looks like line by line. These ranges reflect what we see across South Hills, Woodside, Ridgeline, and the neighborhoods around downtown West Covina in 2026.
| Line Item | Cost Range | Notes |
|---|---|---|
| Demolition & debris hauling | $400 – $900 | Removing the old tub, surround, and any rotted subfloor |
| Shower pan or acrylic base | $600 – $1,800 | Acrylic pans are cheaper; tile-ready mortar pans cost more |
| Wall surround (acrylic or tile) | $800 – $3,500 | Sheet acrylic runs lowest; custom tile with glass accents runs highest |
| Plumbing adjustments | $200 – $1,500 | Moving the drain or supply lines adds labor and permits |
| Shower valve & trim kit | $250 – $900 | Pressure-balanced valves are code minimum; thermostatic costs more |
| Glass door or curtain rod | $350 – $1,800 | Frameless glass runs highest; a simple rod and curtain runs lowest |
| Waterproofing (Schluter or RedGard) | $300 – $900 | Includes membrane, tape, and corner reinforcement |
| Permits | $150 – $500 | City of West Covina plumbing and building permits when required |
| Finish work (caulk, trim, paint) | $200 – $600 | Final sealing, baseboard touch-up, and cleanup |
| Total (labor included) | $3,500 – $10,000 | Most common final: $5,500 – $8,000 |
What pushes a project toward the $10,000 end? Custom tile work, moving the drain to the opposite wall, a niche or bench, replacing a window inside the shower, or rot repair in the floor joists. What keeps it closer to $3,500? A straight 60-inch alcove swap with an acrylic base and matching surround, where the old tub comes out and the new shower goes in without touching the drain location.
One thing we tell every West Covina homeowner: get the price in writing before the first tool comes out. That’s the only way the number on the invoice matches the number you approved. We put it on paper up front, no exceptions.
What Affects Tub-to-Shower Conversion Pricing in West Covina
Pricing shifts from house to house based on several factors, and West Covina’s housing stock makes a few of these more common than you’d expect.
- Age of the home and original plumbing. A lot of West Covina homes were built between the 1950s and 1970s, which means cast iron or galvanized drain lines. If the drain is cracked or rusted when the tub comes out, replacing it adds $500 to $1,200 depending on access.
- Slab foundation access. Many homes in the South Hills and Woodside areas sit on slab foundations. Moving a shower drain on a slab means cutting concrete, which adds $1,000 or more compared to homes with raised foundations and crawl space access.
- Bathroom size and layout. A compact 5-by-8 foot bathroom with an alcove tub is the cheapest scenario. Walk-in tubs or freestanding tubs surrounded by walls on all three sides can require more custom work.
- Waterproofing method and shower system. A Schluter Kerdi system with membrane and drain costs more than a basic acrylic pan, but it opens up tile design options and carries manufacturer warranty backing. Schluter edge trim (the metal strip that waterproofs where your tile meets the floor) is a small line item that adds up across a full surround.
- Level of finish. Fixtures from Kohler or Moen, porcelain or ceramic tile, and a frameless glass door will move the total up compared to builder-grade acrylic and a curtain rod.
- Stopping point for other bathroom updates. If the shower valve replacement reveals old copper that needs repiping, or the toilet flange is cracked next to the tub, you’re suddenly looking at additional work outside the original scope. We see this often enough in West Covina that we flag it early.
How to Save on Tub-to-Shower Conversion
The biggest cost drivers are drain relocation, custom tile work, and rot repair. Avoid moving the drain if you can, and choose a straight alcove configuration where the new shower occupies the old tub footprint. Here’s what actually moves the number:
- Keep the existing drain location. This is the single biggest money saver. Moving a drain 12 inches can add $800 to $1,500 in labor and materials.
- Choose an acrylic base with a matching surround. It installs in a day or two, costs less than tile, and holds up well in West Covina’s hard water conditions.
- Use a curtain rod instead of glass. A $150 rod and $50 curtain versus $800 to $1,800 for a framed or frameless glass door. You can always add glass later.
- Handle any rot or water damage in the same phase. If you discovered moisture damage under the tub, fixing it now is cheaper than waiting. Catching it during a conversion means the walls are already open, so the labor is incremental, not a separate trip.
- Get a fixed written bid, not time-and-materials. Time-and-materials jobs are open-ended by design. A fixed written price puts the risk where it belongs: on the contractor to estimate accurately.

FAQs – Tub-to-Shower Conversion Cost
Is it cheaper to convert a tub to a shower or replace the tub?
A tub-to-shower conversion in West Covina ranges from $3,500 to $10,000, while full tub replacement with new surround typically runs $2,500 to $6,000. The conversion costs more because it involves plumbing changes, a new shower pan, and often relocation of the drain or supply lines. That said, a conversion adds more resale value for most West Covina homes because buyers overwhelmingly prefer low-barrier showers over tubs.
How long does a tub-to-shower conversion take?
Most tub-to-shower conversions in West Covina take 3 to 5 business days from demo to final caulk. A basic acrylic swap can finish in 2 days. Custom tile work, slab-cutting for drain relocation, or rot repair can stretch the timeline to a week or more.
Do I need a permit for a tub-to-shower conversion in West Covina?
Yes, if plumbing is being moved or replaced, the City of West Covina generally requires a plumbing permit. A straight swap with no drain movement and no valve replacement may not need one, but most conversions touch the valve or drain in some way. Sawyer Remodeling handles permitting as part of the written scope. Get the full picture on the work involved on our Tub-to-Shower Conversion in West Covina page.
What’s the most expensive part of a tub-to-shower conversion?
Custom tile work and plumbing relocation are the two biggest ticket items. Tile walls with glass accents can run $2,500 to $3,500 alone, while moving a drain on a slab foundation adds $1,000 to $1,800. The shower pan itself is usually under $1,000 for an acrylic base, which is why acrylic conversions stay at the low end of the $3,500 to $10,000 range.
Can you do a tub-to-shower conversion in one day?
One-day tub-to-shower conversions exist, but they’re typically limited to acrylic panels over an existing tub with no plumbing changes. For a true tub-to-shower conversion in West Covina, with the tub removed and a shower pan installed, plan on 2 to 5 days. Any company promising a one-day conversion on a slab foundation with plumbing changes is cutting corners on waterproofing.
Does a tub-to-shower conversion increase home value in West Covina?
For most West Covina homes, yes. Buyers in this market consistently rank a walk-in shower as more desirable than a tub-only bathroom, especially for older adults and families with young children. A well-executed conversion with proper waterproofing and good fixtures can return much of its cost at resale, though it’s a decision you should make for your own use first.
Why do some West Covina quotes vary by thousands of dollars?
The spread between a $3,500 conversion and a $10,000 conversion usually comes down to four things: waterproofing method, tile vs. acrylic, drain relocation, and glass door vs. curtain. A contractor quoting low is often leaving something out, so always get the line items in writing and compare apples to apples.
