What does a tub-to-shower conversion involve?
A tub-to-shower conversion typically costs $3,500–$9,000 for an acrylic panel system (1–3 day install) or $10,000–$15,000+ for custom tile — the biggest price driver is whether your drain and valve can stay put or need to move.
Keeping the existing plumbing in place saves $1,000–$3,000 compared to relocating the drain or valve. Most acrylic conversions qualify; custom tile layouts often don't.
Most likely causes
| Cause | How to tell | The fix | Typical cost |
|---|---|---|---|
| Acrylic panel conversion | Best for: replacing a standard tub with a low-maintenance shower in 1–3 days | Contractor removes tub, installs prefab acrylic walls and pan over existing plumbing — no tiling required | $3,500 – $9,000 |
| Custom tile walk-in shower | Best for: full bathroom remodel or when you want a specific look; takes 1–2 weeks | Demo tub, waterproof substrate, tile walls and floor — drain may need repositioning | $10,000 – $15,000+ |
| Drain or valve relocation | Best for: custom layouts where the showerhead or drain position needs to change | Plumber opens floor/wall, moves drain line and rough-in plumbing before any finish work | Add $1,000 – $3,000 |
| Accessibility package | Best for: mobility-limited or aging-in-place needs; low-threshold or zero-entry required | Add grab bars, fold-down bench, low-threshold or curbless entry during the conversion | Add $800 – $2,500 |
| Substrate or subfloor repair | Best for: older bathrooms with soft floors, musty smell, or tile popping off walls | Demo reveals rotted studs or subfloor — must be repaired before waterproofing and finish | Add $500 – $2,000 |
Try this first (before you pay anyone)
- Measure your existing tub footprint (usually 30×60 in or 32×60 in) — this determines whether a prefab acrylic kit fits without moving the drain.
- Check the drain location: if the drain is centered or offset toward one end, many acrylic conversion kits can work without plumbing changes.
- Ask any contractor for a substrate inspection before signing a contract — rotted studs or soft subfloor are extremely common in older bathrooms and will add cost if discovered mid-job.
- Get at least two quotes: national franchise brands (Bath Fitter, Re-Bath, Jacuzzi Bath Remodel) often run 30–60% above local contractors for comparable acrylic work.
Hire a contractor when…
- You want a curbless or zero-entry shower — those require proper slope-to-drain work that needs a licensed plumber and often a permit
- The floor feels soft or spongy near the tub — that's subfloor rot and it needs to be scoped before any conversion starts
- The drain or valve needs to move — permit-required plumbing work in most jurisdictions
- You're adding grab bars for mobility support — structural backing must be installed correctly to hold load
Reglaze vs. convert vs. full remodel
If your tub is structurally sound but cosmetically dated, reglazing ($300–$600) buys 5–10 years without any demo. If you genuinely want a shower — for accessibility, convenience, or because no one uses the tub — a conversion makes financial sense. Just know that removing the only tub in a home can affect resale value; the standard real-estate advice is to keep at least one tub if you have only one bathroom.

Related questions
How long does a tub-to-shower conversion take?
An acrylic panel system typically takes 1–3 days from demo to usable shower. Custom tile work takes 1–2 weeks because of waterproofing cure time and multiple tile-setting stages.
Do I need a permit for a tub-to-shower conversion?
If plumbing stays in place, many jurisdictions don't require a permit for a straight swap. The moment the drain or valve moves, you almost certainly need a permit — and an inspector will want to see the rough plumbing before walls close up.
Will removing my tub hurt my home's resale value?
It can — but only if it's the last tub in the house. Buyers with kids and real-estate agents consistently say 'keep at least one tub.' Converting a second bathroom tub to a shower is generally a non-issue.
What is a one-day tub-to-shower conversion?
One-day conversions use prefabricated acrylic wall panels and a shower pan that install directly over the existing plumbing without tiling. They're fast and durable, but your style options are limited to what the manufacturer stocks.
