What are the exact dimensions of every Ella walk-in tub model?

Ella publishes an exact actual size for each model on its specification drawing, and those figures, not the rounded size in the model name, are what you measure your bathroom against. The lineup runs from the Mobile at 26 inches wide by 45 inches long to the ShaK at 36 by 72 inches and the Big4Two at 36 by 80 inches, with the 30 by 52 inch footprint the most common and seat widths from 19 to 29 inches. What are the standard dimensions of a walk-in tub? explains what each dimension means; this page gathers the published exact figures by footprint so you can check which models clear a given opening, such as a 70 inch wall.

Exact Dimensions by Footprint

The figures below are the ones printed on current Ella spec drawings and in the published model guides. Models are grouped by footprint, and the last column answers the question people ask most often, whether the tub clears a 70 inch opening. Where a figure has not been published the cell says not listed.

What the table means: everything at 60 inches or less clears a 70 inch space, the Big4One at 66 inches is the one large model that does, and the 72 inch tubs and the Big4Two do not fit no matter how the walls are finished. Width is the second check. A 30 inch tub drops into a standard alcove, the 32 and 33 inch tubs need a slightly deeper space, and the 36 inch tubs need a bathroom planned around them. Within a footprint, the exact figures separate models that look alike by name: the Elite and the Standard are both 30 by 52 tubs, but the Standard is 29 5/8 by 52 3/4 inches and 37.5 inches tall, while the Elite is 30 by 52 by 35.

Why the Name and the Drawing Differ

The size in a model's name is a rounded nominal figure. A tub sold as 28 inches measures 27.5 inches on the drawing, a tub described as a 5 foot tub can measure 59.5 inches long, and a nominal 60 inch shell measures about 59 3/4 inches. Those differences are normal rounding in the product name, not an error in the drawing, and the actual inch figure on the current specification drawing is always the one to measure against. When a metric figure printed beside an inch figure disagrees with it, the inch figure is the correct one. Each model's product page has a Downloads tab with that model's spec sheet, and the team at (800) 480-6850 can confirm the current spec sheet figures for your contractor if you name the models you are considering.

Which Models Fit a 70 Inch Opening

A 70 inch wall is a common question because it sits between the 60 inch standard alcove and the 72 inch long tubs. Every model at 60 inches or less clears it with room to spare, including the Ultimate and Zen60 at 30 by 60, the Deluxe at 30 by 55, the Elite at 30 by 52, the Royal at 32 by 52, the Petite at 28 by 52 nominal and the Flow at 28 by 48. The Big4One at 33 by 66 inches is the closest large model. The ShaK at 72 inches long and the LayDown72 at 71 3/4 inches overall are too long, and so are the Escape at 72 inches and the Big4Two at 80 inches. When a tub is shorter than the opening, an extension panel can be cut down to fill the gap so the tub still meets the wall, which is how a 52 or 60 inch model finishes cleanly in a 70 inch space. Walk-In Tub and Shower Base Sizes and How to Measure for Fit covers the extension panels.

Measure the finished opening, not the framing. Finished wall to finished wall, often called tile to tile, is always smaller than stud to stud, and in one common case a bathroom framed for a standard tub measures only 58 1/4 inches tile to tile. That is why a nominal 60 inch tub measuring 59 3/4 inches is a very tight fit in a 60 inch alcove, as Will a 60 Inch Tub Fit a 60 Inch Alcove? explains, while the same tub has comfortable room in a 70 inch opening.

Widths, Heights and the 34 Inch Question

Published widths across the line are 26, 27, 28, 30, 32, 33 and 36 inches, and one width that does not exist is 34 inches. A space with about 34 inches of room is usually fitted with a 32 inch tub. At the narrow end, the Transfer30 has an actual width of 29 1/4 inches, so it is narrower than the 31 1/2 inch standard bathtub it often replaces and leaves a little room at the front edge. The Monaco is available in a 32 by 53 inch or 32 by 52 inch size.

Heights vary more than most people expect. The reclining LayDown models stand only 21 inches tall, the Petite and the Elite are 35 inches, the Standard is 37.5 inches, and the Lounger and the Escape are 40 inches. Check the height against any window sill, shelf or fixture near the planned location, because a low window that clears a 21 inch LayDown may sit in the way of a 40 inch tub. Laid-Down Walk-In Tub Dimensions and Fit covers the two reclining sizes, 30x60 and 32x72, and the 66 inch long tub that suits a bather around 6 foot 4 or less who wants to spread out.

Measuring the Route in and Confirming the Drawing

The alcove is only half of the fit question. Measure the front door, the hallway, every interior doorway and each corner the tub must turn, then compare them with the actual width on the drawing. The Petite, listed as 28 inches wide, is actually 27 1/2 inches wide, which is the kind of figure that decides whether a tub passes a tight doorway. For the Escape specifically, the tub is 36 by 72 by 40 inches with two facing seats of 27 and 29 inches and about 60 inches of overall soaking length; it will not fit a standard alcove and there is no extension panel for it, so review the drawings with your Ella dealer or the team at (800) 480-6850 before planning around it. For any model, give the team your wall to wall opening and your doorway width and they will match the models that fit.
