Walk-in showers: a U.S. buyer's guide for safer bathing

Walk-in, roll-in or transfer: which one?

"Walk-in" is a sales term, not a code term. It covers anything you can step into without climbing over a tub. The federal ADA Standards only define transfer and roll-in showers, which have stricter numbers. Pick by how the bather moves:

Bather	Usual fit	Entry height
Walks steadily, wants an easier step	Low-curb walk-in	About 2 to 4 in, by product
Uses a cane or walker, or shuffles	Low-threshold walk-in (about 1 in or less)	Near flush
Slides from a wheelchair to a seat	Transfer shower	1/2 in max under ADA rules
Stays in a wheelchair or shower chair	Roll-in shower	1/2 in max under ADA rules

If a wheelchair is likely within a few years, read our roll-in shower guide before you buy a curbed base. Changing your mind later means tearing out the floor. For the federal specs side by side, see ADA showers.

Converting a tub into a walk-in shower

Most U.S. homes built from the 1950s through the 1990s have a 60-inch tub in the hall bath. That alcove is the most common spot for a walk-in conversion because the drain, walls and footprint are already there. A typical job runs like this:

• Tear out the tub and wall surround, then inspect the subfloor and studs for water damage.
• Move or replace the drain to fit the new base. Old galvanized or cast-iron lines are often replaced while open.
• Add wood blocking between studs so grab bars and a seat can go in now or later.
• Set a low-profile base, then wall panels or tile, a hand shower and the valve.

Before you remove your only tub, think about resale and grandkids. In many markets buyers with small children want at least one tub somewhere in the house. If the hall bath is the only one, a walk-in tub may be the better compromise.

Features that do the most for safety

• Grab bars into blocking, not drywall anchors. The ADA uses 33 to 36 inches high and a 250-pound load as its benchmark, a good target at home too.
• A hand shower on a slide bar so a seated bather or a helper can aim the water.
• A fold-down or built-in seat at roughly chair height. The ADA uses 17 to 19 inches.
• An anti-scald valve (pressure-balancing or thermostatic) so a flushed toilet doesn't send a burst of hot water.
• Textured, slip-resistant base and enough light to see the floor.
• Controls reachable from outside the spray, so you can start the water without getting hit by a cold blast.

Materials and regional wear

Acrylic and solid-surface panels have few or no grout lines, which suits anyone who can't scrub on their knees. Tile is the most flexible for odd sizes but needs sealing. In hard-water regions, which include much of the Southwest and parts of the Plains, glass and chrome show mineral spots fast, so many owners pick a curtain or a single fixed panel. In humid Gulf Coast and Southeast homes, a properly sized exhaust fan matters as much as the shower itself. In cold northern states, an exterior-wall shower needs insulated plumbing walls to avoid frozen lines.

Cost ranges

No government source tracks walk-in shower prices. From common contractor pricing, a prefab tub-to-shower conversion in an existing alcove often falls in the range of about $6,000 to $14,000 installed. A custom tile walk-in, a larger footprint or moved plumbing can reach $15,000 to $25,000 or more. Prices run higher in major coastal metros and lower in many rural markets.

Help with paying

Medicare covers durable medical equipment such as walkers, but it generally doesn't pay to remodel a bathroom; see Medicare.gov. Some Medicare Advantage plans include limited home-safety benefits, so call yours. Veterans may qualify for the VA's HISA grant, and those with certain service-connected disabilities for the SAH or SHA grants; details are on VA.gov. Many state Medicaid waiver programs fund home modifications for people who qualify, with limits set by each state. Our roll-in guide has a funding table with current VA figures.

Picking an installer

• Check licensing on your state's contractor board site. Some states license remodelers, others only plumbers.
• Get the threshold height in writing. "Low" can mean 1 inch or 5.
• Ask how the price changes if rot is found under the tub.
• Avoid high-pressure, same-day-only pricing. For most sales of $25 or more made in your home, the FTC's Cooling-Off Rule gives you three business days to cancel. Some states add their own protections.
• Confirm the warranty covers both the product and the labor, and for how long.
