Tub to Shower Conversion Cost 2026: Prices & Options
A tub to shower conversion costs $2,000 to $12,000 in 2026, with most homeowners paying around $7,000 for a mid-range project. The wide range comes down to one big decision: a prefab shower kit or a custom tiled shower.
Prefab kits run $1,000 to $8,000 installed, from basic acrylic surrounds to premium solid-surface systems. A custom tile shower typically costs $3,500 to $15,000, while luxury and curbless walk-in designs run $6,000 to $15,000 or more.
Tub to Shower Conversion Cost Overview
Here is how the main conversion options compare in 2026 contractor pricing.
| Conversion Type | Average Cost (2026) |
|---|---|
| Full conversion, overall range | $2,000-$12,000 |
| National average | ~$7,000 |
| Prefab shower kit | $1,000-$8,000 |
| Custom tile shower | $3,500-$15,000 |
| Luxury shower | $6,000-$15,000+ |
| Curbless walk-in | $8,000-$15,000+ |
| DIY (materials only) | $1,000-$3,500 |
Cost Breakdown: Where the Money Goes
| Line Item | Typical Cost |
|---|---|
| Tub demo and disposal | $450-$2,000 |
| Plumbing changes | $500-$2,000 extra |
| Tile (materials and labor) | $800-$3,000 |
| Shower fixtures | $200-$1,000+ |
| Glass door or enclosure | $200-$2,500 |
| Permits and inspections | $180-$2,000 |
Plumbing is the wildcard. Moving the drain or valve adds $500 to $2,000, and code requires the shower drain to be upsized from the tub’s 1.5-inch line to a 2-inch line. Glass doors average $600 to $1,350 for most projects, though frameless custom glass can reach $2,500.
Prefab Kit vs Custom Tile
Prefab kits ($1,000-$8,000) are acrylic or fiberglass surrounds installed over a new pan. They go in fast, cost less, and never need grout maintenance. The tradeoff is limited sizes and a less custom look.
Custom tile ($3,500-$15,000) gives you any size, layout, and finish, including benches and niches. It costs two to three times more and takes one to three weeks, but it adds more to resale value.
Factors That Affect the Price
- Plumbing relocation. Keeping the drain and valve in place avoids $500 to $2,000 in extra work.
- Drain upsizing. Code requires a 2-inch shower drain versus the tub’s 1.5-inch line.
- Waterproofing. Proper membranes and pans are non-negotiable and add material and labor cost.
- Tile choice. Basic ceramic keeps tile costs near $800; natural stone can triple that.
- Fixtures. A basic valve and head runs $200; thermostatic and multi-head systems pass $1,000.
- Glass enclosure. Most homeowners spend $600 to $1,350; frameless custom reaches $2,500.
- Permits. Plumbing permits run $180 to $2,000 depending on the municipality.
- Structural surprises. Rotten subfloor found during demo adds repair cost.
Timeline: How Long Does a Conversion Take?
A prefab conversion takes 2 to 4 days from demo to first shower. A custom tile conversion takes 1 to 3 weeks, with waterproofing and tile curing setting the pace. The typical sequence:
- Demolition of the tub, surround, and old plumbing (1 day).
- Rough plumbing: new valve, drain upsized to 2 inches, inspection.
- Waterproofing and shower pan installation.
- Tile setting and grouting (several days for custom work).
- Fixture and glass installation, final plumbing inspection.
DIY vs Hiring a Pro
A prefab kit conversion is realistic for an experienced DIYer, with materials running $1,000 to $3,500. You will still likely need a plumber for the drain upsizing and a permit inspection in most jurisdictions.
Custom tile, curbless designs, and any project that moves plumbing belong with a pro. Waterproofing mistakes are the most expensive kind: a slow leak inside a tiled wall can cause thousands in hidden damage. Get a licensed contractor for anything beyond a direct prefab swap.
How to Save Money on a Tub to Shower Conversion
- Choose prefab over custom tile. It cuts the project cost roughly in half.
- Keep the plumbing where it is. Avoiding relocation saves $500 to $2,000.
- Pick a standard glass door. Stock sizes cost far less than custom frameless glass.
- Go mid-range on fixtures. A $300 valve performs like pricier designer models.
- Keep a 10 to 15 percent contingency. Hidden water damage is common once the tub comes out.
- Get three quotes. Bathroom contractors vary widely on the same scope.
Frequently Asked Questions
How much does it cost to convert a tub to a walk-in shower?
A tub to walk-in shower conversion costs $2,000 to $12,000 in 2026, averaging about $7,000. Curbless walk-in designs with tile start around $8,000 and can exceed $15,000.
