The Ella seat pillow riser fits the Elite and most seated walk-in tubs, but the published guides do not list a confirmed fit for every single model, so the right riser is matched to your tub by model and serial number rather than assumed. The riser is a moderately soft foam cushion about 20 1/2 inches long by 13 inches wide by 3 1/2 inches high that holds to the molded seat with suction cups, and it comes as a full rectangle or as a U-shape with a bidet cutout. Our guide What Is a Seat Pillow Riser on a Walk-In Tub? explains the accessory itself; this page answers the fit question model by model.
Why the Answer Is Most Rather Than All
Every Ella walk-in tub has a seat molded into the shell as one piece, so the seat cannot be moved or adjusted, and the riser is the way to sit higher. Seat height is about 17 inches on most models, within the 17 to 19 inch range used for accessible seating, and seat width runs from 19 to 29 inches depending on the tub. The riser is 13 inches wide, which is narrower than the narrowest seat width in the line, so width is rarely what decides fit. Two other things do:
- Which jets sit under the seat. Tubs with an air massage package have bidet air jets at the base of the seat. Those jets have no switch of their own and run whenever the air massage runs, so a tub with bidet jets calls for the cutout riser that leaves them open. Hydro-only and soaking tubs have no bidet jets, so the full rectangle is the natural choice there.
- Where the suction cups can grip. The cups hold only on a clean, flat, smooth section of the shell, away from jets, texture lines and the seat edge. A seat with jets or texture where the cups would land needs the riser positioned with that in mind.
Because the published guides describe fit as the Elite and most seated tubs and name only a few models directly, the safest step for any tub not confirmed below is to share your model and serial number with your Ella dealer or the team at (800) 480-6850 so the right shape is matched to your seat.
What the Published Guides Confirm, Model by Model
| Model | Seat width | Riser fit in the published guides | What it means for you |
|---|---|---|---|
| Elite | not listed | Fits the standard riser | Named directly as a fit; choose rectangle or cutout by therapy package |
| Ultimate | not listed | Standard riser plus a made-to-order 6 inch riser | The 6 inch riser covers the seat jets, so ask about timing and jet coverage before ordering |
| Transfer60 | not listed | Takes the seat riser; no separate back cushion | Seat height can be raised, but there is no matching back cushion for this model |
| Petite | 19 inches | not listed | Narrowest seat in the line; confirm fit with model and serial number |
| Transfer26 | 19 inches | not listed | Same 19 inch seat width as the Petite; confirm fit with model and serial number |
| Transfer32 | 24 inches | not listed | The Hydro + Air package includes 2 bidet jets, so the cutout shape applies if you have air |
| ShaK | 28 inches | not listed | Lists 3 bidet jets among its 37 total jets, so the cutout shape applies |
| TransferXXL | 29 inches | not listed | Widest single seat in the line; the Hydro + Air package includes 2 bidet jets |
The pattern in the table is the practical answer. The three models named in the guides span the Elite, the Ultimate with its extra riser height and a Transfer tub, which matches the guides' wording that the riser fits most seated tubs. For every other model the guides give the seat width and the jet layout but not a fit statement, so the team confirms fit from your serial number rather than from a chart. The seat width figures in the table come from What Are Seat Width and Seat Height on a Walk-In Tub?, which also explains how to measure yourself seated before choosing a tub.
Choosing the Shape Once Fit Is Confirmed
- Standard rectangle. Covers the seat area and adds about 3 1/2 inches of height. It is the shape for a seat with no bidet jets under it.
- U-shape with bidet cutout. Leaves the bidet area open so the air jets at the base of the seat keep flowing. It fits one way and is not reversible, so orient the opening over the jets. What Are Bidet Jets on a Walk-In Tub? explains which packages include them.
- 6 inch riser for the Ultimate. Made to order and covers the seat jets, so it trades jet flow at the seat for extra height.
Bidet jets come only with the air massage package, so if your order was hydro-only or a soaker, there are no bidet jets to keep clear and the standard riser is the one to ask for. If you are not sure which package is on your tub, the team will ask for it first, since that decides whether bidet jets are present at all.
Adding a Riser to a Tub That Is Already Installed
The riser is an accessory rather than a built-in part, so it can be added after your original purchase and after the tub is installed. It sits on the seat with suction cups; no drilling or adhesive touches the shell. That puts it in the same group as seat pillows, the head pillow and the swivel tray in Can Features Be Added to an Ella Walk-In Tub After It Is Installed?, as opposed to the therapy systems and the heated seat, which are built into the shell at the factory. A seat riser has also been offered as an alternative through the free accessory for reviews program when one was available.
The contrast with the seat belt is worth knowing. The seat belt bracket mounts below the seat with drilled fasteners, and the team confirms the bracket location for your model before anyone drills, as explained in Is There a Seat Belt for the Walk-In Tub?. The riser needs none of that, which is why it can be tried on a seated tub without any permanent change to the tub.
Keeping the Riser in Place
Suction cups hold only on a clean, flat, smooth section of the shell. Clean the seat and the cups with soap and water, dry the cups, and press them flat, away from jets, texture lines and the seat edge. Cups are simple wear items: if one stretches, pops out of its mount or is missing, open a ticket at ellasbubbles.com/support with a photo of the cushion and the cup mount and a replacement is arranged. If the seat still feels too low with the riser in place, remember that the shell itself cannot be changed; on the Ultimate the 6 inch riser is the next step, and on other models the team can advise from your model and serial number.
