Walk-in showers: types, costs and how to plan one

What counts as a walk-in shower?

A walk-in shower is a standalone shower without a tub. It often has a level floor and a partial wall or fixed glass screen instead of a door, which makes it easier to step in and out^[1]. That easy entry is why many people replace a tub with one as they get older. More than one out of four older adults falls each year, according to the CDC^[4].

Prefab or tiled?

There are two main ways to build one.

	Prefab (one-piece or kit)	Custom tiled
What it is	A molded base and wall panels in fiberglass, acrylic or cultured marble[1]	A waterproofed base and walls finished in ceramic, porcelain, stone or glass tile[1]
Installed cost	$1,000 to $8,000[1]	$3,500 to $15,000[1]
Labor share of that	$500 to $4,300[1]	$1,400 to $9,000[1]
Sizes	Standard sizes, limited finishes[1]	Built to fit the room

Prices are national ranges from HomeGuide, read in October 2026^[1]. Your city, your bathroom's age and how much plumbing has to move will change the number. For local ranges see the city guides below and our walk-in shower cost guide.

A prefab unit is the lower cost and faster choice^[1]. Tile costs more because it takes more skilled labor, but it lets you pick the exact size, the bench and the niche locations.

Curbless and zero-entry showers

A curbless (also called zero-entry or roll-in) shower has a floor that is level with the bathroom floor, so there is nothing to step over^[1]. For public buildings, the ADA Standards limit a roll-in shower threshold to ½ inch^[3]. Homes are not bound by those standards, but they are a good yardstick for "truly curbless."

Curbless is harder than it looks. The shower floor still has to slope to a drain, so the floor under it is usually lowered or the bathroom floor is raised. Even the ADA rules allow a 2 inch threshold in some existing buildings where a ½ inch one would disturb the reinforcement in the floor slab^[3]. On a concrete slab home, ask your contractor early whether a zero-entry floor means cutting the slab.

What size do you need?

Size	Who it fits	Source
36 x 36 inches	Small baths; also the ADA "transfer" shower size, used with a seat	[1][3]
30 x 60 inches	HomeGuide's standard walk-in size; also the ADA minimum for a roll-in shower, with a 60 inch opening	[1][3]
60 x 72 inches and up	Large primary baths, dual shower heads	[1]

For a wheelchair, HomeGuide notes the entry should be at least 36 inches wide^[1].

Glass, open or partial wall?

Many walk-in showers use one fixed glass panel and no door at all^[1]. If you add glass doors or panels, federal law covers them: the CPSC safety glazing standard applies to shower doors and enclosures and to bathtub doors and enclosures^[5]. Ask for glass that is labeled as meeting that standard.

An open design with no glass needs enough length so water stays in the shower. A rule many installers use is to keep the shower head pointing away from the opening.

Seats, grab bars and a handheld shower

These are the features that make a shower safe for the long run.

• Grab bars. The ADA Standards place grab bars 33 to 36 inches above the floor and require the bar, fasteners and wall to hold a 250 pound force^[3]. A towel bar is not a grab bar.
• Seats. A fold-down or fixed seat lets you sit while washing. In homes covered by the ADA rules, a seat can be skipped if the walls are reinforced so one can be added later^[3]. That is a smart request for any remodel: ask for solid blocking in the walls now, even if bars come later.
• Ventilation. EPA advises running a fan or opening a window while showering and keeping indoor humidity below 60%^[6]. A walk-in shower with no door lets steam spread, so the fan matters more.

How contractors quote a walk-in shower

A shower job usually involves a demolition crew, tile setters, a plumber and sometimes an electrician, and labor can be 40% to 60% of the total^[1]. Most contractors give one project price rather than hourly rates. A good written estimate should list^[7]:

• The work to be done and the materials, by brand and model where possible
• Demolition and haul-away
• Plumbing changes, such as moving the drain or valve
• Glass, seat, grab bars and niche
• Permit fees and who pulls the permit
• A start and completion date and the price

The FTC suggests getting more than one estimate and asking why if they differ a lot^[7]. It also lists a contractor who asks you to get the building permits yourself as a warning sign^[7].

How long does it take?

HomeGuide says a typical bathroom remodel takes 3 to 8 weeks, and a small or simple one can finish in 3 to 4 weeks^[2]. A prefab swap is at the short end. Tile, drain moves and permit inspections push it longer. Ask for a written schedule that shows when the bathroom will be out of use.

Permits and licensed plumbers

Most walk-in shower jobs touch plumbing, and plumbing usually needs a permit.

• Texas. State law makes cities over 5,000 people require a permit for plumbing work, except for repairing leaks or replacing faucets, ballcocks, water control valves, disposals or toilets^[8]. A shower is not on that list. Plumbers are licensed by the Texas State Board of Plumbing Examiners (TSBPE). An owner may do plumbing in their own homestead without a license^[8], but the city permit still applies.
• Chicago. The city's Express Permit Program covers repairing or replacing an existing plumbing fixture, while altering or extending a plumbing system goes through a different path^[9].
• Older homes. In homes built before 1978, anyone paid to disturb painted surfaces must be an EPA lead-safe certified firm^[10].

See the city guides for the local rules.

How to choose a contractor

• Get it in writing. Contractor name, address, phone, license number, start and finish dates, and every verbal promise belong in the contract^[7].
• Check the license. Consider only licensed and insured contractors, and confirm the license with your state or local government^[7]. The plumber should hold the state plumbing license where one is required.
• Ask for proof of insurance^[7].
• Get the warranty in writing. Ask what the installer covers (leaks, grout, workmanship) and for how long, and what the product maker covers.
• Do not pay it all up front. The FTC says not to pay the full amount first and to hold the final payment until you are satisfied^[7].
• Know your cancel right. A contract signed at your home should explain your right to cancel within three business days^[7].

When to call a pro

• Any job that moves the drain, the valve or a wall: a licensed plumber and, where your city requires it, a permit.
• A curbless shower on a concrete slab: ask a contractor how the floor will be lowered and sloped before you commit.
• Grab bars on tile or drywall with no blocking behind it: have them anchored into solid framing or rated anchors.
• A home built before 1978: hire a lead-safe certified firm for demolition^[10].
