How Do I Choose a Walk-In Tub With a Low Threshold and Slip-Resistant Floor?

Every Ella walk-in tub already comes with a low step-in threshold and a textured, slip-resistant floor, so you do not need to hunt for a model that has those two features. The choice that matters for safe daily use is the door style, followed by the seat, the grab bars and the space in your bathroom. The standard safety features are listed in Which Ella Walk-In Tubs Have Textured Floors, Grab Bars and Easy Entry?, and this page turns them into a simple order of decisions so you can choose with confidence.

Start with What Every Model Already Includes

It helps to know what is not a decision at all. The first video on this page shows the low threshold, easy entry design and the textured slip resistant floor, and describes entering and exiting as safe, easy and convenient, even from a wheelchair. In the second video an owner describes how the low threshold makes getting in and out of the tub a breeze. These basics are built into the whole line:

  • A low step-in threshold and a textured, slip-resistant floor on all walk-in models.
  • A seat height of 17 inches on most models, similar to a standard chair. The seat is molded and not adjustable.
  • Deck and wall-mounted grab bars placed for entry and exit. Most seated tubs include one or two deck-mount bars, and more can be added to the surrounding walls.
  • Fast-fill faucets with an extendable hand shower, so you can rinse while seated.
  • An optional heated seat and backrest, plus easy-touch or digital controls.

Because these features are standard, comparing models for safe daily use comes down to door style, size and therapy package and not to whether the safety basics are included. If you are still getting familiar with the category, What is a walk-in tub, and how is it different from a regular bathtub? explains the door, the threshold, the seat and the floor in more detail.

Choose the Door Style That Matches How You Get in

The door decides how you approach the tub, where you stand while you close it and how much room you need beside it. Ella builds five door styles, and each one suits a different way of entering.

Glass side-entry doorLayDown 30x60, LayDown 32x72Tempered glass side door in a brushed aluminum framenon répertoriéeBathers who want to recline at full length

Here is what those differences mean in your bathroom. With an inward door you hold the grab bar, step over the low threshold, close the door while standing, then sit and fill, so it suits a bather who is steady on their feet for those few moments. An outward door leaves the inside of the tub clear, since there is nothing to step around once you are in. The L-shaped door is the one built for wheelchair users, because it opens wide enough for a seated side transfer and is designed to fit over a toilet in a tight room. The Ultra uses the inward design in a brushed aluminum frame with frosted glass, and the Companion and Escape two-seat tubs use an inward stainless door as well, so couples and larger bathers have inward options too.

Look at the Threshold, the Seat and the Grab Bars for Your Own Body

The number that decides how easy a tub is to enter is the step-in threshold, not the outside height of the tub. A walk-in tub is entered through a sealed door, so its wall can be taller without being harder to get over. The Elite, for example, has an actual size of 30 inches wide by 52 inches long by 35 inches high, yet what you step over is only the low threshold in the door opening. On models like the Capri that step-in is roughly 3 1/2 to 4 inches. Do they make a bathtub that is only 15 inches high? explains why overall height and step-in height are two different things.

When you compare models, check these three points:

  1. The step-in. Ask your Ella dealer or the team at (800) 480-6850 for the threshold figure on the specific model you like, and compare it with what you can comfortably lift a foot over today.
  2. The seat. Most models have a 17 inch seat height, similar to a standard chair. The seat is molded and not adjustable, so sit on a chair of that height at home and see how standing up from it feels.
  3. The grab bars. Most seated tubs include one or two deck-mount bars. Think about which hand you reach with as you step in, and plan extra bars on the surrounding walls if you would like more support.

Match the Tub to the Bather and to Who Helps

Once the door style is settled, the next choice is the kind of bathing the tub has to support. What is a walk-in tub and who is it designed for? describes the groups each tub is built around, and they map neatly onto the lineup:

  • Independent seated bathing. Any of the inward or outward seated models gives you the low threshold, the textured floor and the chair-height seat.
  • Wheelchair transfer. The Transfer models are built so a bather can move in from a wheelchair, and the TransferXXL at 36 by 55 inches is a wheelchair accessible, bariatric model for bathers who need extra width.
  • Assisted bathing. The HoistAssist pairs a transfer tub with its own battery hoist for a bather who cannot bear weight or slide across, and the HomeCare is designed exclusively for assisted bathing with a caregiver present.
  • Lying down. Only the two LayDown tubs are built for a full recline, and both keep a low threshold and a textured slip-resistant floor. Lying down in a seated walk-in tub is not recommended and could be hazardous, as Can you lie down in a walk-in tub? explains.

Space rarely rules a tub out. Every Ella tub fits the three-wall alcove a standard 60 inch bathtub used to occupy, and most 52 and 55 inch models use an extension panel to fill the gap at one end. Plan around the actual size on the spec sheet, and leave room for an outward door to swing if that is the style you choose.

Habits That Keep Daily Use Safe

The threshold and the floor do their best work when the bath follows the same simple routine each day. You enter first, close the door, then fill. After the bath you open the drain, wait, then open the door. Ella walk-in tubs drain by gravity through two 2-inch drains, and once connected to a proper 2-inch drain line a tub typically empties in two minutes or less, so the wait is short.

While bathing in a seated tub, sit fully in the seat with your back against the backrest. The owner's manuals ask bathers not to slouch, not to lie down in the footwell and not to put their feet up on the opposite side, because the footwell is the deepest part of the tub. Any bather who is paralyzed or does not have all limbs functioning must be attended by a caregiver at all times and use an installed safety belt. With those habits in place, the low threshold, the textured floor, the seat and the grab bars work together every single day.

Questions fréquentes

Do all Ella walk-in tubs have a slip-resistant floor?
Yes. Low step-in thresholds and textured, slip-resistant floors are on all Ella walk-in models, including the two LayDown tubs. Because the feature is standard, you can choose your model by door style, size and therapy package.
How high is the step into an Ella walk-in tub?
What you step over is the low threshold in the door opening, not the full height of the tub. On models like the Capri that step-in is roughly 3 1/2 to 4 inches. For the figure on another model, ask your Ella dealer or the team at (800) 480-6850.
Which door style is best for a wheelchair user?
The Transfer26, Transfer30, Transfer32, Transfer60 and TransferXXL have an extra-wide L-shaped door that swings outward a full 172 degrees. It is designed to fit over a toilet, and it allows a seated side transfer from a wheelchair. The TransferXXL at 36 by 55 inches is the bariatric model for bathers who need extra width.
Can the seat height be adjusted on a walk-in tub?
No. The seat is molded into the tub and is not adjustable. Most Ella models have a seat height of 17 inches, which is similar to a standard chair.
Can more grab bars be added around the tub?
Yes. Most seated tubs include one or two deck-mount grab bars placed for entry and exit. More bars can be added to the surrounding walls for extra support.
Is an inward or outward door safer for daily use?
Both styles come with the same low threshold and textured floor, so the better choice depends on how you enter. With an inward door you step in, close the door while standing, then sit, and the water holds the door shut once the tub fills. An outward door leaves nothing to step around inside the tub, and the outward L-shaped door is the one designed for wheelchair transfers.
