Ella walk-in tubs are built in a set of standard footprints, from the compact 26 by 45 inch Mobile up to 36 by 72 inch models, and the quickest way to compare them is to put each model's actual exterior size, seat width and door style side by side in one table, then test those figures against your alcove, your doorway and the person who will bathe. The size in a model's name is a rounded nominal figure, so every comparison has to use the actual size printed on that model's current spec sheet. What are the standard dimensions of a walk-in tub? collects the verified exterior figures by model, and this page shows how to compare them, adds the seat and door figures, and works through the pairings people ask about most.
Start Every Comparison from the Actual Size
Ella sells tubs under nominal sizes such as 30 by 52 or 28 by 52, and the spec drawing often shows a slightly different number. The Petite is sold as a 28 inch tub and measures 27.5 inches wide, and a tub described as a 5 foot tub can measure 59.5 inches long. Those half-inch differences are normal rounding in the name, not an error in the drawing, and the inch figure on the current spec sheet is the one to measure against. Where a metric figure printed beside an inch figure disagrees with it, the inch figure is the correct one.
Three more rules keep a comparison honest:
- Compare the tub length against the finished opening, wall to wall, rather than the framing. Ella tubs shorter than 60 inches include an extension panel that fills the gap to the wall, so a 52 inch tub still fits a 60 inch alcove.
- Compare the tub width against the depth of the alcove from the back wall out into the room, and on an outward-swing model add floor space in front for the door to open.
- Compare the two smaller tub dimensions against the narrowest doorway and hallway on the delivery route, because the crate is opened outside and the tub is carried in by its frame.
Confirm the drain side as well. On an Ella walk-in tub the door and the drains sit on opposite sides: a right-side door tub has its drains on the left, and a left-side door tub has its drains on the right as you face the tub. How do I measure my bathtub and alcove for a replacement? walks through taking the length, width and height of the opening itself.
The Common Models Side by Side
The figures below are the actual sizes and seat widths that appear on the current spec sheets and in the model guides. Where a figure is not published in those sources the cell says not listed, and the spec sheet for that model is the place to confirm it.
| Model | Actual size | Seat width | Door | Best for |
|---|---|---|---|---|
| Mobile | 26 x 45 inches | 20 inches | Outward-swing U-shape | The smallest footprint, for a 45 inch space or a tight doorway |
| Petite | 27.5 x 52 x 35 inches | 19 inches | Inward-swing stainless steel | The narrowest seat Ella offers, for a smaller bather and a narrow door |
| Elite | 30 x 52 x 35 inches | 22 inches | Inward-swing stainless steel | The common 30 by 52 footprint on the lower 35 inch platform |
| Capri | 30 x 52 inches | 20 inches | Outward-swing U-shape | The outward-swing door in the standard 30 by 52 footprint |
| Monaco | 32 x 52 inches | 23 inches | Outward-swing U-shape | Two extra inches of width for a broader bather in a 60 inch alcove |
| Lounger | 27 x 60 x 40 inches | 20 inches | Outward-swing U-shape | A narrow tub with 60 inches of length to stretch out |
| Ultimate | 30 x 60 inches | 21 inches | Inward-swing stainless steel | The extended 60 inch stainless-door model with triple massage |
| Big4One | 33 x 66 inches | 24 inches | Outward-swing U-shape | A large bather with 66 inches of wall and room for an outswing door |
Read the table in two directions. Across the 52 inch tubs the exterior width is what separates the models, and each inch of width shows up in the seat: the Petite gives 19 inches of seat in 27.5 inches of tub, the Elite 22 inches in 30, and the Monaco 23 inches in 32. Down the length column, the 60 and 66 inch models fill a standard opening outright and trade the extension panel for interior length. The door column matters as much as the numbers, because an inward-swing door needs no floor space in front of the tub, while the outward-swing U-shape door, a plastic composite and tempered glass door that opens 165 degrees and locks with a 3-latch gear and shaft mechanism, needs a clear arc in front of the door side before the tub is set.
The Pairings People Compare Most
- Elite and Ultra. Both are 30 by 52 inch tubs with an inward-swing door and a 22 inch seat, so the choice comes down to the door and the interior. The Elite uses the brushed stainless steel door with frosted tempered glass and ships with a removable swivel tray, a reversible end panel and a 7 inch extension panel for a 60 inch alcove. The Ultra has a frameless brushed aluminum door with a frosted glass panel, 42 inches of interior length, 24 inches of shoulder width, an ADA compliant 17 inch seat height, a 19 inch seat length and a 17 1/2 inch soaking depth, and it adds a stainless steel towel bar and dual 2 inch drains. The swivel tray fits the Elite but is not compatible with the Ultra.
- Ultimate and Ultra. The Ultimate is the 30 by 60 inch extended model with a 21 inch seat and the stainless steel door family's lower seat, about 15 inches above the footwell, while the Ultra is 30 by 52 with the higher 17 inch seat. The swivel tray is standard on the Ultimate and does not fit the Ultra. Both always include at least one massage system, and the Ultimate is the triple massage model.
- Capri and Lounger. Both share the outward-swing door and a 20 inch seat. The Capri is 30 by 52 inches and the Lounger is narrower and longer at 27 by 60 inches, so the Lounger suits a bather who wants length and a bathroom with a full 60 inches of wall.
- Elite, Royal, Petite and Deluxe. These share the stainless steel inward-swing door and differ in one dimension each. The Royal is sold as a 32 inch tub, measures 31.5 by 52 by 35 inches and carries a roomier seat than the Elite's 22 inches. The Petite is 27.5 inches wide with the 19 inch seat. The Deluxe is 30 by 55 inches with a 21 inch seat, so it is the longer tub and the Elite is the more compact footprint with the slightly wider seat.
Seat Width, Door Opening and Soaking Depth
Seat width and door opening are both printed on each model's specification drawing. Across the seated models, seat widths run from 19 inches on the most compact sizes to 21 or 22 inches on the common 52 inch footprints, with the Flow at 20 inches, the Transfer60 at 22 inches and the TransferXXL at 29 inches. Door openings follow the door family more than the overall size: the Capri measures 17.25 inches and the Elite 16.25 inches.
The first video on this page shows how to size yourself before you size the tub. Measure your hips while seated, because the tub seat must be wider than your hip size, check your shoulder width the same way, and for length sit in a chair facing a wall and measure from head to feet in a relaxed position. It also explains that soaking depth is set by three figures: the interior length, the seat length and the depth from the top of the seat to the center of the overflow. The second video applies those figures to the transfer-style tubs. The 32 by 52 inch model has a 24 inch seat, 44 inches of interior length and a 15 1/2 inch seat length, the 30 by 52 inch model has a 22 inch seat with the same interior length and seat length, and the Transfer32 soaking depth is 14 1/2 inches. The video also points out where the actual exterior width is marked so you can check the tub against your home.
Fitting a 60 Inch Alcove or a 65 Inch Space
The Monaco is the model most often asked about for a 60 inch alcove. It measures 32 inches wide by 52 inches long with a 23 inch seat, and it fits a 60 inch opening because the extension panel bridges the gap between the 51 3/4 inch tub and the 60 inch wall, and the panel can be cut down if the gap is smaller. Measure the finished opening rather than the framing, since a bathroom framed at 60 inches can measure less once the end walls are tiled. Plan the route in as well, with at least a 32 inch doorway recommended for the Monaco and about 21 inches of clearance in front for the outswing door.
A 65 inch space leaves room for any model in the line, including the longer ones such as the Deluxe at 30 by 55 inches, the Ultimate at 30 by 60 inches, and the LayDown60 at 30 by 60 inches, which is designed for both bathing and showering and stands only 21 inches tall, as Laid-Down Walk-In Tub Dimensions and Fit describes. Every Ella tub ordered with a deck-mount fast-fill faucet comes with a five setting hand shower on a 5 foot hose, and for a true overhead shower the 10 inch rain shower column kit connects to the faucet diverter, adjusts up to 7 feet tall and must be fitted before the tub is finally installed, so choose it with the order. A tempered glass screen is also available to keep water off the floor.

Which Sizes Are in Stock
Stock is tracked by the full configuration rather than by model name, so one door side, therapy package or color can be on hand while another waits on a later production run. Ella tubs are assembled and tested to order, and the team confirms current timing for each specific order. Give your Ella dealer or the team at (800) 480-6850 the model, door side, therapy package, color and any accessories, or open a ticket at ellasbubbles.com/support, and they will confirm availability for that exact build and send the current spec sheet for each model you are weighing so you can lay them next to each other.
