How to convert a tub to a walk-in shower

The steps

1. Remove the tub and inspect the wall and floor behind it.
2. Adjust plumbing and the drain for a shower.
3. Waterproof the base and walls.
4. Install the base and surround — liner, acrylic, one-day system, or custom tile.
5. Add safety features — a low or curbless threshold, grab bars, a bench or fold-down seat, a hand-held shower, and slip-resistant flooring.

Safety features worth specifying

• Low or curbless threshold — the single biggest safety gain.
• Grab bars mounted into blocking, where you actually reach.
• A seat — built-in bench or fold-down.
• Hand-held shower on a slide bar.
• Anti-scald valve and slip-resistant floor.

What it costs and how long

Cost runs from about $1,500 for a liner to $18,000+ for full custom — see the cost breakdown or estimate yours with the conversion cost estimator. Timelines range from a single day for a one-day system to 5–10 days for custom tile.

Deciding between a shower and a walk-in tub

A conversion suits people who want to step in and stay standing or seated; a walk-in tub suits those who want to soak. Price both if you are unsure.
