What is the shortest walk-in bathtub Ella's Bubbles makes?

Updated September 2026

The shortest walk-in bathtub in the Ella's Bubbles line depends on which way you measure. Front to back, the Front Entry is the shortest at 40 inches, but it is entered from the front and needs 32 inches of width. Among side-entry tubs the Mobile is the shortest at 26 inches wide by 45 inches long, which is why What is the smallest bathtub size you can buy for a bathroom? names it the smallest tub Ella makes, and if shortest means the lowest tub to step into and sit down in, the Petite, Elite and Royal stand 35 inches tall with the lower seat.

Three Ways a Tub Can Be the Shortest

People type the same question with three different things in mind, and each one points to a different tub.

  • Shortest along the wall. This is the length figure in every model's width by length size, and it decides whether the tub fits the opening. The Front Entry is 40 inches front to back, the Mobile is 45 inches long, and the Flow is 48 inches long.
  • Shortest to step into and sit in. This is the tub's height, which sets the deck and the seat. The Petite, Elite and Royal are the shortest seated tubs at 35 inches because they carry a lower seat, which is the platform many shorter bathers find easiest to settle into.
  • Shortest seat. The Flow's seat is 20 inches wide by 13 inches long, the shortest seat length listed, which suits a smaller bather.

Decide which of the three you are asking about before you compare drawings, because a tub that wins on one can lose on another. The Mobile, for instance, is the shortest side-entry tub but stands 39 1/4 inches tall, while the 35 inch Petite is 52 inches long.

The Shortest Ella Tubs Compared

The table uses the actual sizes from the current spec sheets rather than the nominal names, listed from the shortest length upward.

ModelActual size (W x L x H)SeatDoorWhat it means
Front Entry32 x 40 x 40 in.25 in.Outward-swing U-shapeThe shortest footprint front to back; entered from the front; suits single-wide mobile homes
Mobile26 x 45 in. (brochure size), 39 1/4 in. high19 to 20 in.Outward-swing U-shape, 165 degree swingThe shortest side-entry tub; a 45 inch space, a corner, or a 25 inch doorway with the frame removed
Flow28 x 48 x 36 1/2 in.20 x 13 in.Inward acrylic S-shapeThe shortest of the inward-swing acrylic door models and the shortest seat length listed
Petite27.5 x 52 x 35 in. (28 x 52 nominal)19 in.Inward stainless steel, removableThe lowest deck at 35 inches with the narrowest seat in the line
Elite30 x 52 x 35 in.22 in.Inward stainless steel, removableThe lowest deck with a wider 22 inch seat; the usual 52 inch tub for a standard bathroom
Transfer2626 x 52 x 40 in.19 in.Outward L-shape transfer doorThe narrowest 52 inch tub, built for wheelchair transfer
Lounger27 x 59 x 40 in.20 in.Outward-swing U-shapeA narrow tub at nearly full alcove length

Length decides whether a tub fits the opening, width decides whether it passes the doorway and how much elbow room the bather has, and seat width decides comfort once seated. The Front Entry is the shortest tub front to back, but it needs 32 inches of width and is entered from the front rather than the side, which is why it suits rooms where the tub faces the door. The Mobile wins on length among side-entry tubs and ties the Transfer26 on width, which is why it is the answer to the smallest tub question. The Flow is the shortest of the inward-swing acrylic door models. A bather who wants the stainless door or a wider seat gives up a few inches of floor and steps up to the Petite or the Elite at 52 inches, and those two are also the lowest tubs in the table at 35 inches tall.

What the 45 Inch Mobile Keeps and Gives Up

The Mobile keeps the essentials of a full-size walk-in tub: a full seat, a grab bar, and a hydro or air and hydro therapy package. Its compact frame changes a few figures you should know before you order. The interior length is 38 7/8 inches, the seat is 19 inches on the video and 20 inches in the manual, and the tub stands 39 1/4 inches high with a step-in of about 3 3/4 inches. The door opens outward through a 165 degree swing, and the tub can pass a 25 inch doorway with the frame removed, which is the detail that makes it the answer when a standard 52 inch tub will not fit the room or will not get through the door. Like the Front Entry, Capri and Lounger, the Mobile belongs to the U-shape family, whose outward-swinging door is made of PVC composite and tempered glass with a 3-latch gear and shaft mechanism.

Short Tub, or Short Bather? Measure the Bather First

A short tub and a short bather are different questions. Ella's measuring video does not ask how tall you are. It asks you to sit in a chair facing a wall, in a relaxed position, and take three measurements:

  1. Your hips while seated. The tub seat must be wider than this number.
  2. Your shoulder width while seated, so the tub has the proper shoulder room for your body size.
  3. Your length from head to feet while seated, to gauge the tub length that fits you.

Compare those numbers with the drawings and specifications for each model, and be exact, because different body sizes require different size tubs. Ella seat widths run from 19 inches on the Petite and Transfer26 to 29 inches on the TransferXXL, so the seated hip figure narrows the field quickly. Bigger is not automatically better: the extra-large tubs with very long seats are designed for taller bathers and can be uncomfortable for an average or shorter person. A small footprint and a small seat do not always come together, so decide which matters more before you compare drawings. What is the smallest walk-in tub for a petite bather? puts the compact models next to the bather's measurements, and What size walk-in tub fits a five foot or six foot person? compares both ends of the height range for a household with one of each.

When the Room Is Not the Limit

If the alcove is a standard 60 inches and the doorway is not a problem, the shortest tub is rarely the best one. The Ultimate, at 30 by 60 inches and 35 3/4 inches tall, is the full-length tub Ella's video presents for taller bathers, and the Deluxe at 30 by 55 inches with a 46.5 inch interior length gives extra legroom without a 60 inch footprint. At the other end of the line, What is the biggest walk-in bathtub size you can buy? compares the ShaK at 36 by 72 inches and the Big4One at 33 1/8 by 66 inches. Whatever the size, use the current spec sheet for each model rather than an older chart or video, and ask your Ella dealer or the team at (800) 480-6850 to confirm the actual size before your contractor opens the wall.

Common Questions

What is the shortest walk-in tub Ella's Bubbles makes?
Front to back, the Front Entry is the shortest at 40 inches, but it is entered from the front and needs 32 inches of width. Among side-entry tubs the Mobile is the shortest at 26 inches wide by 45 inches long, and it is the model named as the smallest tub Ella makes.
Is the 45 inch Mobile really a full walk-in tub?
Yes. It keeps a full seat, a grab bar and a hydro or air and hydro therapy package, with an interior length of 38 7/8 inches and a seat of 19 to 20 inches. The tub stands 39 1/4 inches high with a step-in of about 3 3/4 inches.
Which Ella tubs are the lowest to step into and sit in?
The Petite, Elite and Royal are the shortest seated tubs at 35 inches tall because they carry a lower seat. That lower platform is the one many shorter bathers find easiest to settle into, even though these tubs are 52 inches long.
Will the shortest tub fit through a narrow doorway?
Width, not length, decides the doorway. The Mobile can pass a 25 inch doorway with the frame removed, and the Mobile and Transfer26 are the narrowest tubs at 26 inches wide. Confirm the doorway and hallway measurements with your Ella dealer or the team at (800) 480-6850 before ordering.
Does a short tub automatically suit a short bather?
No. Ella's measuring video asks for your seated hip width, shoulder width and head-to-feet length rather than your height, and the tub seat must be wider than your seated hip measurement. A shorter bather often prefers the lower 35 inch platform of the Petite or Elite over the shortest footprint.
