What is a roll-in shower and who should get one?

Updated September 2026

A roll-in shower is a shower built on a curb-less base, so a wheelchair or shower chair rolls straight in with no lip to step or roll over. Ella's wheelchair accessible roll-in base comes in three standard sizes with the drain position specified when you order, and it is the right choice when the person bathing stays seated in a wheelchair or shower chair. Should I choose a walk-in tub or a roll-in shower? weighs it against a walk-in tub.

What Makes a Shower a Roll-In Shower

  • A curb-less pan. All of Ella's standard roll-in bases are ADA curb-less pans, so there is no threshold to step or roll over.
  • The lowest entry Ella makes. AcrylX barrier-free bases have a beveled roll-in entry of 3/4 inch to 1 1/8 inch depending on size, and SMC bases are 1 inch or 1 1/8 inch. By comparison, one-piece and three-piece shower stalls have a 4 inch threshold, and a 3 inch step-in base is offered for anyone who prefers a slightly raised edge.
  • A collapsible shower dam. Roll-in and barrier-free bases ship with a self-adhesive collapsible rubber dam that keeps water in the stall. The video below shows the dam being measured, set with silicone, and then compressing under the wheels and springing back to hold the water in.
  • A finished acrylic surface. Ella shower pans are finished acrylic, so they need no tile and are ready to use once installed.

Sizes and Drain Positions

The three standard bases share a 60 inch length and come 30, 32 or 36 inches wide. Each is available with a left or right drain, and the 32 by 60 inch barrier-free base is offered in left and right configurations and is ready to ship. Tell the team where your existing drain line sits in the floor and it confirms which drain position matches your size. Full details are in Wheelchair Accessible Shower Base Sizes, Drain Positions, and What Is Sold Separately. When a standard size will not fit, Ella makes custom rectangular bases up to 44 inches wide by 80 inches long with the drain placed left, right or center, at least 9 inches from each wall, as explained in Who Makes Custom Shower Pans and Bases for Accessible Showers?.

Who Should Get a Roll-In Shower

Choose a roll-in shower when the person bathing stays in a wheelchair or shower chair and needs to roll straight in with nothing to cross. Caregiver options include a weighted anti-bacterial nylon curtain, a stainless curtain rod and a slide bar with hand shower. A seat is optional: folding benches and seats rated from 300 to 600 pounds, or a 36 by 60 base with a molded seat. Choose a walk-in tub instead when you want to sit and soak, add therapies, and still shower from the seat with the hand shower.

Putting a Complete Roll-In Shower Together

Shower products are sold per item rather than as a single bundle. A complete roll-in shower is the base in your size and drain position, a wall system sized to the base, and accessories such as grab bars or a shower door. Wall choices include a plain white acrylic three-piece panel kit, a CNC engraved pattern in acrylic and a marble-look three-piece panel kit, and Ella's wall panels are 98 inches high. Your contractor sets the base, connects the drain and finishes the walls around it. The full range of bases, walls and the 8 inch L-shaped filler piece is listed in Shower Bases, Walls, and Filler Pieces. Bases and walls are available through your Ella dealer or the team at (800) 480-6850.

Common Questions

How is a roll-in shower different from a step-in shower base?
A roll-in shower has a curb-less base, with an AcrylX entry of 3/4 inch to 1 1/8 inch or an SMC entry of 1 inch or 1 1/8 inch, so a wheelchair rolls straight in. Ella's one-piece and three-piece stalls have a 4 inch threshold instead. A 3 inch step-in base is offered for anyone who prefers a slightly raised edge.
What sizes does the Ella roll-in shower base come in?
The three standard sizes are 30 by 60, 32 by 60 and 36 by 60 inches, each with the drain position specified when you order. When none of those fits, a custom rectangular base can be made up to 44 inches wide by 80 inches long. Bases with angled or curved edges are not offered.
How does water stay in a roll-in shower with no curb?
Roll-in and barrier-free bases ship with a self-adhesive collapsible rubber dam. The wheels roll over the compressible material on the way in and out, and the dam returns to its original shape to keep the water in the stall. The video shows it being installed with silicone and then compressing under a wheelchair.
Can a roll-in shower have a seat for the bather?
Yes, though a seat is optional. Folding benches and seats rated from 300 to 600 pounds are available, and the 36 by 60 base can be ordered with a molded seat. A slide bar with hand shower helps a seated bather or a caregiver.
Does the roll-in base come with the walls and door?
No. Shower products are sold per item, so the base, a wall system sized to it, and accessories such as grab bars or a door are put together separately. Your Ella dealer or the team at (800) 480-6850 can confirm what you need for a complete roll-in shower.
Who should choose a walk-in tub instead of a roll-in shower?
A walk-in tub suits someone who wants to sit on a molded seat and soak, add therapies such as hydro massage or a heated seat, and still shower from the seat with the hand shower. A roll-in shower suits someone who stays in a wheelchair or shower chair while bathing.
