Four seated Ella walk-in tubs stand under 36 inches tall: the Elite, Petite and Royal at 35 inches, and the Ultimate 30x60 at 35 3/4 inches. The LayDown 30 by 60 is much lower at 21 inches, but it is a reclining tub with no seat. Every other seated model is taller, including the Monaco at 39 1/4 inches, and Low Windows and Countertops: Checking Tub Height Before You Order explains how to measure the sill or countertop you are working under.
Tub Heights Against a 36 Inch Limit
Height here means the outside wall of the tub, from the floor to the top of the deck, which is the height figure printed on each model's spec sheet or technical drawing. The table sorts the models whose heights are published, shortest first. Where a width, length or seat figure is not printed in the material behind this page, the cell says not listed rather than guessing.
| Model | Height | Other published figures | Under 36 inches? |
|---|---|---|---|
| Petite | 35 inches | 27.5 x 52 inches actual, sold as a 28 inch tub | Yes, the narrowest listed footprint |
| Elite | 35 inches | 30 x 52 inches | Yes, the common 30 by 52 footprint |
| Royal | 35 inches | not listed | Yes |
| Ultimate 30x60 | 35 3/4 inches | 59.5 inches long | Yes, and it fills a 60 inch alcove without an extension panel |
| LayDown 30x60 | 21 inches | 60 inches long by 30 inches wide, 15 inch soaking depth, no seat | Yes, but you recline rather than sit |
| Flow | 36 1/2 inches | not listed | No, the closest miss |
| Monaco | 39 1/4 inches | 32 x 52 inches, 23 inch wide seat, outward-swing door | No |
| Deluxe | 39 inches | not listed | No, tall on purpose with a higher seat |
What the table means: if your limit is a 36 inch window sill, the choice is among the three 35 inch tubs and the Ultimate, and even those need a few extra inches above the deck on any wall side for the wall finish, so measure to the bottom of the trim before deciding. The Flow misses by half an inch. The Standard, Zen and Zen60 at 37 1/2 inches, the Standard60 at 38 inches, the Deluxe at 39 inches and the outward-swing door family at about 40 inches are all over the line. A tub with a seat runs from 35 to 40 inches across the whole lineup, and 40 inches is the tallest Ella makes. The full set of widths and lengths is in What are the standard dimensions of a walk-in tub?.
The Monaco Under a 36 Inch Window Sill
The Monaco's technical drawing gives an overall height of 39 1/4 inches. The deck is the highest structural point of the tub, so that is the figure to compare with your window. A 36 inch sill sits below the Monaco's deck, so this is not a straightforward fit: a standard installation wants the sill above the deck. Send your sill height and a photo to your installer before ordering so the window can be worked into the plan, and ask your Ella dealer or the team at (800) 480-6850 to go through the measurements with you. The Monaco also needs 21 inches of clearance in front of it for the outward-swing door. The Monaco video shows the actual external dimensions of the tub, including that door clearance, along with its 23 inch wide seat, 16 inch seat length, 26 inch shoulder width and 42 inch interior length. If staying under the sill matters more than the Monaco's outward door and wider seat, the Elite, Petite and Royal at 35 inches and the Ultimate 30x60 at 35 3/4 inches are the seated tubs that clear it.
Why the Short Tubs Are Short
The difference is mostly the seat. The Deluxe, the outward-swing U-door family, the Transfer family, the Ultra and the two-seat tubs carry a seat about 17 inches high, in the range used for accessible seating, which is easier to rise from and pairs with a low step-in. The 35 inch Elite, Petite and Royal carry a lower seat, and a lower seat means a shorter tub overall. Shorter bathers often prefer the lower seat, and taller bathers usually prefer the higher one. Tub height is not something that can be special-ordered in either direction, so a 39 inch tub cannot be built at 35 inches, and nothing with a seat is 32 inches or under. How big are walk-in tubs, and how tall do they stand? sets the heights beside the widths, lengths and capacities of the larger models.
The LayDown When the Limit Is Lower Still
Under 24 inches there is one family: the LayDown. The 30 by 60 stands 21 inches to the deck edge, with an actual size of 60 inches long by 30 inches wide and 21 inches high. Low as it is, it still soaks 15 inches deep, compared with a standard tub depth of 11 inches, because you recline in it rather than sit. The LayDown video shows the 3060 with its interior soaking length of 53 inches and 25 1/2 inches of width, the straight and narrow sidewalls that give more interior room than a curved-wall tub, the tempered glass door in a stainless steel frame and the low threshold. It is the answer when a window or a vanity rules out every seated tub.
Measuring the Limit Before You Choose
- Measure from the finished floor to the bottom of the window trim, not the glass. The trim is what the tub deck and the wall finish behind it must clear.
- Measure from the finished floor to the underside of any countertop, cabinet or shelf that overhangs the tub space.
- Open the spec sheet for the model under Download Specifications on its product page and read the actual height. The size in a model name is nominal: the Petite is sold as a 28 inch tub and measures 27.5 inches wide.
- Allow a few extra inches above the deck on any wall side for the wall finish.
- Check length and door side as well. A compact 52 inch tub goes into a 60 inch alcove with an extension panel, and on every Ella tub the door and the drains are on opposite sides, so choose the door side that puts the drains over your existing drain. Will a Walk-In Tub Fit Where My Old Tub or Shower Stall Is Now? runs the whole fit check.
