Walk-In Shower Conversion Cost: Tub to Shower (2026)
Converting a standard bathtub to a walk-in or roll-in shower eliminates the step-over that causes most bathroom falls. Costs range from $1,500 for a basic tub-to-shower conversion to $8,000+ for a fully custom zero-threshold (roll-in) shower. Here's what determines the price and whether it's the right choice vs. a walk-in tub.
Key Takeaways
- A basic prefab tub-to-shower conversion costs $1,500–$3,000. A custom zero-threshold roll-in shower costs $6,000–$15,000.
- A zero-threshold (curbless) walk-in shower is safer than a walk-in tub for most seniors — nothing to step over.
- Basic conversions take 1–2 days; custom tile work takes 3–5 days; full bathroom remodels take 1–2 weeks.
- Adding a built-in bench and grab bars during conversion costs $500–$1,500 — much cheaper than retrofitting later.
- Use a CAPS-certified contractor to ensure ADA-compliant slope drainage and proper blocking for grab bars.

Frequently Asked Questions
What is the difference between a walk-in shower and a roll-in shower?
A walk-in shower typically has a small curb or low threshold (1–2 inches). A roll-in shower is completely curbless (zero threshold) — a wheelchair can roll directly in. Roll-in showers are required under ADA guidelines for accessible bathrooms. For aging in place, a zero-threshold shower is the safest option.
How much does a tub-to-shower conversion cost?
A basic conversion with a prefabricated shower unit costs $1,500–$3,000. A custom-tiled walk-in shower with glass doors costs $4,000–$8,000. A fully custom ADA-compliant roll-in shower with built-in bench and grab bars costs $6,000–$15,000. Plumbing relocation (if needed) adds $500–$2,000.
Is a walk-in shower safer than a walk-in tub for seniors?
For most seniors, a zero-threshold walk-in shower is safer than a walk-in tub because there is nothing to step over or sit inside while waiting to drain. Walk-in tubs require sitting inside during fill and drain. The safest bathroom configuration for seniors is a roll-in shower with a fold-down bench and grab bars.
How long does a tub-to-shower conversion take?
A basic conversion using a prefab shower unit takes 1–2 days. A custom-tiled walk-in shower typically takes 3–5 days. A complete bathroom remodel with a roll-in shower may take 1–2 weeks. Most work requires no permit, but adding a new wall or moving plumbing may require one.
Can the conversion be done in a small bathroom?
Yes. Standard bathtub space (60 x 30 inches) can be converted to a walk-in shower of the same footprint. For a zero-threshold (roll-in) shower with turning radius for a wheelchair, ADA recommends at least 60 x 30 inches of shower space plus a 60-inch turning radius in the bathroom — which requires more space.
What is a prefab shower insert and is it a good option?
A prefabricated shower insert (acrylic or fiberglass pan with surround panels) is installed over the existing tub footprint, rather than tiling from scratch. Cost is $1,500–$4,000 installed vs. $5,000–$12,000 for a tiled custom conversion. Prefab inserts are faster (1–2 days) and lower maintenance than tile (no grout to reclean). For aging-in-place, confirm the insert has a low or zero threshold and integrated grab bar mounting points.
Does removing a bathtub hurt home resale value?
Removing the only bathtub in a home can reduce resale value, as many buyers — especially families with young children — require at least one tub. If you have a second bathroom with a tub, converting the master bathroom to a walk-in shower has minimal resale impact and often improves value. If converting the home's only tub, discuss the tradeoff with a local real estate agent before proceeding.
