Tub-to-Shower Conversion: What to Expect From Start to Finish

HomePro Help guide · Updated October 16, 2026

If stepping over the side of your bathtub has started to feel like a chore, you're not alone. A tub-to-shower conversion replaces an existing bathtub with a walk-in shower, usually in the same footprint. It's one of the most common bathroom updates homeowners ask about. Here's what the process typically looks like, so you know what to expect before you talk to anyone.

What a tub-to-shower conversion involves

Most conversions follow the same basic steps, though every bathroom is a little different:

1. In-home assessment. A provider measures the space, checks the plumbing and the condition of the walls and subfloor, and talks through options with you.
2. Removing the old tub. The tub, and often the surrounding wall surface, is taken out.
3. Plumbing changes. The drain and valve may need to be moved or adjusted for a shower.
4. Waterproofing and base. A shower pan or base is installed and the area is waterproofed.
5. Walls and fixtures. New wall panels or tile go up, followed by the shower valve, shower head, door or curtain rod, and any accessories you choose.

Common options to ask about

• Low-threshold or curbless entry – a lower step-in edge, which many people find easier to use.
• Wall material – acrylic or composite panels versus tile. Panels usually have fewer grout lines to clean; tile offers more design choices.
• Built-in seat or bench – handy for shaving legs or sitting while you shower.
• Handheld shower head – useful for rinsing and for people who prefer to sit.
• Glass door or curtain – glass looks clean and modern; a curtain keeps the opening wider.
• Grab bars and shelves – easier to add while the walls are open.

How long does it take?

Timelines vary widely. A straightforward swap using prefabricated wall panels can be quite quick, while a custom tiled shower with plumbing changes takes longer. Things that tend to add time include moving the drain, repairing hidden water damage, custom tile work and local permit requirements. Ask each provider for an estimated schedule in writing.

What affects the cost?

We don't quote prices, because they depend on your home, your area and the materials you pick. The biggest factors are usually:

• The size of the space and whether the layout changes
• Plumbing work needed for the new drain and valve
• Wall material (panels vs. tile) and the type of shower base
• Glass doors, built-in seats and other upgrades
• Any repairs found once the old tub is removed

Getting more than one quote is a good way to understand what's reasonable where you live.

Is a conversion right for you?

A conversion often makes sense if no one in the home uses the tub for baths, if getting in and out of the tub is becoming difficult, or if the bathroom simply needs an update. If you still enjoy soaking, a walk-in tub may be worth comparing. If you have only one bathtub in the house, it's worth thinking about whether anyone (for example, small children) still needs it.

Before you hire

Whoever you choose, check that they are licensed and insured for this kind of work in your state, and get the scope, price and timeline in writing. Our guide to questions to ask a bathroom remodeling contractor covers the essentials.
