Which walk-in tub features make bathing safer for seniors?

The features that make a walk-in tub safer for a senior are the ones that remove a risky movement: a low threshold in place of an 18 to 22 inch tub wall, a chair-height seat in place of the tub floor, a door that seals and locks, grab bars, a textured floor, and a hand shower that reaches you where you sit. Every Ella walk-in tub is built around those basics, as Are Walk-In Tubs a Good Choice for Seniors and Aging in Place? explains. This page takes the features one at a time, with the published figures, so you can see which ones matter most for the person who will be bathing.

A Low Step-In Threshold

A conventional bathtub asks the bather to lift a leg over the rim, lower down to the floor of the tub, and later stand up from that floor on a slippery surface. The first video on this page shows the Ella answer to the first of those moves: a low threshold entry with a textured slip-resistant floor, usable even from a wheelchair. The threshold is the lip in the door opening measured from the finished floor, and on Ella tubs it runs roughly 3.5 to 7 inches. Published drawings and team figures put the Monaco at 3 5/8 inches, the Mobile at about 3 3/4 inches, the Transfer family and the Capri around 3 1/2 to 4 inches, the Big4One and ShaK around 5 inches, the Ultra about 6 inches and the Elite about 6 1/2 inches. The legacy S-Class was offered with a 3 inch threshold in place of the 6 inch height, a version that requires subfloor access to the drains.

Recessing the drain below the subfloor can bring a current model down to about 3 to 3 1/2 inches, but the apron or end panel is then trimmed, and cutting those parts voids warranty coverage on the altered panels. Do not confuse the step-in with the overall height of the tub. The LayDown60 is the lowest Ella tub overall at 21 inches, yet it is the threshold, not the outside height, that decides how easy a tub is to enter, as What is the lowest height bathtub for easy entry? sets out.

A Seat at Chair Height, Wide Enough for the Bather

The second risky move, lowering to the tub floor and standing up from it, is removed by the molded seat. Seat height is about 17 inches on many models, including the Ultra, most outward-door tubs and the Transfer family, about 15 inches on the stainless-door family, the Mobile and the Escape, and about 16 inches on the Front Entry. On the Ultra the product video describes the 17 inch seat height as ADA compliant, with a 19 inch seat length for leg support and a 17 1/2 inch soaking depth measured from the top of the seat to the center of the overflow. Seat width matters as much as height: the seat must be wider than the bather's seated hip measurement, and Ella seat widths run from 19 inches on the Petite and Transfer26 to 29 inches on the TransferXXL, with the Royal's 23 inch seat the widest in the stainless family. All seated Ella tubs are designed for sitting; lying down in a seated walk-in tub is not recommended and could be hazardous, and a bather who wants to recline should look at the LayDown models with their glass side door and 15 inch soaking depth.

Read the table from the bather's point of view. A person who shuffles rather than lifts a foot gains most from the Monaco and Mobile thresholds, while a person who struggles to rise from a low chair gains more from the 17 inch seats on the Ultra and the Transfer family than from an inch less at the door. A wheelchair user is usually served by a Transfer model, where the seat height and the L-shape opening do the work of the threshold. If the person is broad in the hips, start from seat width and only then look at the step.

A Door That Seals and Locks

The bather is enclosed by a latched door for the whole bath. On the legacy S-Class a chrome stainless steel door latch pulls the door tight against its seal, and on the Royal the removable stainless steel door swings inward, so nothing swings out into the room and the door can be removed for cleaning. Outward-swing doors need more clear space in front of the tub but make entry easier, and on those models a caregiver locks the handle from outside. The Front Entry puts an outward-swinging U-shape door on the 32 inch end of the tub so the bather walks straight in from the front, and it is the one Ella model not ordered as left-hand or right-hand. The Mobile's outward U-door has a 165 degree swing and a 19 1/4 inch opening, which is why its profile asks you to leave clear floor in front. For side-door models the door side is chosen as left or right as you face the tub, and it follows the house drain: a right-side door tub drains on the left, and a left-side door tub drains on the right. Every Ella tub has a door, including the LayDown models; a doorless version is not offered, as Can I Order an Ella Walk-In Tub Without a Door? explains.

Grab Bars, a Textured Floor, a Hand Shower and Easy Drains

On the S-Class 30x52 and 30x60 the video tour shows the textured floor, wall and deck grab bars, a built-in towel rack and a 21 inch wide seat, so the bather steps in near floor level, turns, and sits. Most current models carry grab bars on the deck, the wall or both, and the 5 foot hand shower means washing does not require reaching or standing. The Ultra adds a stainless steel towel bar and a frameless brushed aluminum door with a frosted glass panel described as warm to the touch; the on-screen and spec-sheet figures for the Ultra, Standard, Flow and S-Class are collected in Ultra, Standard, Flow and S-Class on Video. Draining is designed for the same seated bather: oversized easy-turn drain openers with a large 2 inch drain and a safety chain let the tub empty without bending for a small stopper, and the Ultra uses dual drain technology with two 2 inch four-port drains. The acrylic surface is durable and easy to clean, which matters when the person cleaning the tub is also the person bathing in it.

Temperature Control and Assisted Bathing

Scalding is the hazard the step and the seat do not address. A tub ordered with an Ella thermostatic faucet package includes a built-in Ella Thermostatic Control Valve that mixes hot and cold to a set temperature. The second video on this page shows the Ella HomeCare assisted bathing tub, which goes further: the temperature is preset at the touch of a button, an internal tank fills with water at that temperature and stops on its own, and once the bather is inside with the door closed a single fill button sends the tank's water into the tub and shuts off automatically. The HomeCare has an extra wide entry and an easy sit-down height for moving in from a wheelchair, adjustable leveling legs to fine-tune that height, 50 inches of internal length and 25 inches of interior width, and it is built for a bather who needs a caregiver's help. Which family suits a given person, from seniors who bathe alone to wheelchair users in the Transfer family, is laid out in What is a mobility tub and who is it designed for?. Many models can also be ordered as a soaking-only tub with no jets, pumps or electrical, so none of the safety features above depend on choosing a therapy package. Ella does not send technicians; the tub is connected by a local licensed plumber and electrician, and the team at ellasbubbles.com/support or (800) 480-6850 can help you compare models.
