Ella does not offer a walk-in tub with an overall height of only 15 inches. The lowest-profile Ella tubs are the LayDown models, and the LayDown60 stands 21 inches high with a soaking depth of 15 inches, which is almost certainly the figure you have seen. Seated walk-in tubs are taller still because they are built around a chair-height seat, and the number that decides how easy a tub is to enter is the step-in threshold, not the outside height. The LayDown sizes, faucet rules and features are laid out in The LayDown Walk-In Tubs: 30x60 vs 32x72 Sizes, Faucet Options, and Features.

Where the 15 Inch Figure Comes from

The two LayDown tubs are the Ella models built for lying down rather than sitting. Both have a soaking depth of 15 inches, compared to about 11 inches in a standard bathtub, so the 15 inch number describes how deep the water can be, not how tall the tub is. The LayDown60 measures 30 inches wide by 60 inches long by 21 inches high overall. The LayDown72 is 32 inches wide by 72 inches long. Both have a tempered glass side-entry door in a brushed aluminum frame, a low threshold, straight sidewalls, a textured slip-resistant floor and a single oversized 2 inch brass drain.

Why a Walk-In Tub Is Taller Than a Regular Bathtub

A regular bathtub is an open basin you climb into over a high wall. A walk-in tub is entered through a sealed door, so the wall can be taller without being harder to get over. Inside is a molded seat at chair height, a non-slip textured floor and, on nearly every Ella model, a built-in grab bar. That seat is why seated models stand well above 15 inches. The Elite, for example, has an actual size of 30 inches wide by 52 inches long by 35 inches high, and the HomeCare assisted-bathing tub stands 41 3/8 inches high. What you actually step over is the low threshold in the door opening. On models like the Capri that step-in is roughly 3 1/2 to 4 inches. The seven differences between the two tub types are explained in Walk-In Tub Versus a Regular Bathtub.

Will a Taller Tub Fit Where the Old One Was?

Height rarely decides fit, because a walk-in tub goes into the same three-wall opening a standard 60 inch bathtub used to occupy. Every Ella tub fits that alcove, and most 52 and 55 inch models use an extension panel to fill the gap at one end so the installation looks built in. The walls above the deck are then finished with tile or a surround over a tile flange. Plan around the actual size on the spec sheet rather than the nominal name, and measure the opening wall to wall at the back and at the front. Read What Is an Alcove Installation for a Walk-In Tub? before framing.

If a Low Tub Is Really About Easier Bathing

Many people searching for a very low bathtub want to stop climbing over a tub wall. A walk-in tub solves that with its door and seat, and a LayDown model solves it for anyone who wants a full-body soak lying down. If a shower would suit the bather better, Ella offers fold-down and fold-up seats and left-hand or right-hand folding bench seats for shower use, described in Shower Seat Sizes and Options. Your Ella dealer or the team at (800) 480-6850 can help match the bather to the right option.

Common Questions

Is the LayDown walk-in tub only 15 inches high?
No, the LayDown60 stands 21 inches high overall. The 15 inch figure is its soaking depth, which is deeper than the roughly 11 inches of water a standard bathtub holds. The tub is entered through a low-threshold tempered glass side door.
How high is the step into an Ella walk-in tub?
The step-in threshold is the number that matters for entry, not the outside height of the tub. On models like the Capri the step-in is roughly 3 1/2 to 4 inches. Every model's threshold is listed on its spec sheet, and the team can confirm the figure for the model you are considering.
Why are walk-in tubs taller than a regular bathtub?
A walk-in tub is built around a chair-height molded seat, so the shell has to be tall enough to hold water above the seat. Because you enter through a door rather than over the wall, the extra height does not make the tub harder to get into. The Elite, for example, is 35 inches high with a low door threshold.
Will a taller walk-in tub fit my existing bathtub alcove?
Yes, every Ella tub fits the three-wall alcove where a standard 60 inch bathtub sat. Most 52 and 55 inch models use an extension panel to fill the remaining space at one end. Measure the opening wall to wall and plan around the actual size on the spec sheet.
Can I lie down in a seated walk-in tub instead?
Lying down in a seated walk-in tub is not recommended. If a full-body soak is what you want, the LayDown60 and LayDown72 are the Ella tubs built for lying down. Both have straight sidewalls, a textured floor and a 15 inch soaking depth.
