How Much Does a Tub-to-Shower Conversion Cost?
A tub-to-shower conversion costs $3,000–$12,000 depending on materials and scope. The major cost driver is whether you’re installing a prefab shower kit ($3,000–$5,000) or building a custom tiled shower ($6,000–$12,000+). Plumbing modification is required in both cases—the drain location changes and the shower valve needs to be repositioned.
One-day tub-to-shower conversions (Bath Fitter, Re-Bath) run $5,000–$12,000. These use acrylic panels over existing walls. The convenience premium is 30–50% over a traditional conversion, but you avoid 1–2 weeks of construction.
Resale consideration: If you’re converting the only bathtub in the house, be aware this can reduce resale value. Homes with zero bathtubs sell for 10–15% less in most markets. If you have at least one other tub, the conversion is fine.

Frequently Asked
Common questions.
How much does a tub to shower conversion cost?
A tub-to-shower conversion costs $3,000–$12,000. Prefab shower kits run $3,000–$5,000 installed. Custom tiled showers with glass enclosure run $6,000–$12,000. The conversion requires plumbing modification ($500–$1,500) to relocate the drain and valve.
How much does a one day tub to shower conversion cost?
One-day tub-to-shower conversions cost $5,000–$12,000 through companies like Bath Fitter and Re-Bath. These install custom acrylic panels over existing walls and a new shower base in a single day. The price includes materials, installation, and basic plumbing.
Does converting a tub to a shower decrease home value?
Only if it’s the last bathtub in the house. Homes with zero tubs sell for 10–15% less in most markets because families with young children require at least one tub. If you have another tub in the house, the conversion typically adds value.
Do you need a permit for a tub to shower conversion?
Yes, in most jurisdictions. The plumbing modification (drain relocation, valve repositioning) requires a plumbing permit. Cost: $75–$300. If electrical is involved (adding recessed lighting, heated floor), you’ll need an electrical permit too.
