Does This Tub Include the Heated Seat and Backrest? Confirming the Configuration Before You Order

Updated September 2026

Whether a walk-in tub includes a heated seat and backrest depends on the exact configuration you order, not on the model name and not reliably on the letters at the end of a listing's model number. On some listings the letters HB in the model number refer to the faucet package, not to the heated seat, so a tub can carry an HB suffix and still ship without seat heating. The only safe way to confirm is to check the feature list for that exact configuration, and if the heated seat and backrest is not listed, ask your Ella dealer or the team at (800) 480-6850 for the configuration that includes it before you order.

Why the Model Number Can Mislead

Ella walk-in tubs are built to order, and the same base model is offered in many configurations: door side, therapy package, faucet package and comfort options such as the heated seat and backrest. Listing numbers combine those codes, and the same letters can mean different things on different listings. One listing may use HB for the faucet, while a different listing uses a separate model number to identify the version with the heated seat. Treat the suffix as a hint, never as confirmation.

What the Heated Seat and Backrest Does

The heated seat and backrest warms the surfaces you sit and lean against, so you are not sitting on cold acrylic while the tub fills and the water level rises. It is a comfort option selected when the tub is configured and built into the tub at the factory. The full range of therapy and comfort options is described in the walk-in tub therapy options and features overview, and what each package includes is summarized in the therapy package inclusions cheat sheet.

How to Confirm Before Ordering

  1. Read the feature list for the exact configuration, not the general model description. If the heated seat and backrest is not listed as included, assume it is not.
  2. Do not rely on suffix letters in the model number. Ask directly, and make sure the heated seat and backrest appears on your order confirmation.
  3. If you want the option, ask your Ella dealer or the team for the configuration that includes it; a listing that includes it names the heated seat and backrest in its feature list and often carries a different model number.
  4. Confirm the therapies you want at the same time, such as hydro, air, foot massage or chromatherapy, because these are factory-built and the choices are made together.

Can It Be Added Later?

The heated seat and backrest is selected when the tub is configured, and the therapy systems are installed at the factory, so plan for them when you order. What can and cannot be changed after purchase is explained in can I add air jets, a heater or a heated seat later. If you are unsure which options a given model supports, the team can confirm them for the model you are considering. What ships with every order, regardless of options, is listed in what comes with your walk-in tub order.

If the Tub Arrived Without the Switch

If you ordered the heated seat and backrest and there is no control for it on the deck, check your order confirmation first and then open a ticket with your serial number. The steps are in my tub was supposed to have an LED light or heated seat but there is no switch.

Common Questions

Does HB in the model number mean heated seat and back?
Not necessarily. On some listings HB refers to the faucet package and the tub does not include seat heating. Confirm from the feature list or by asking your Ella dealer or the team before you order.
Can the heated seat and backrest be added after installation?
The heated seat and backrest is selected when the tub is configured and built in at the factory. Contact the team at (800) 480-6850 to discuss your situation, and read the linked article on adding options later before assuming it can be retrofitted.
How do I know which model number includes the heated seat?
Ask your Ella dealer or the team for the configuration that includes it. The feature list for that configuration states the heated seat and backrest explicitly, and it often carries its own model number.
Can all of the options be added to the model I want?
Options are selected when the tub is configured. Ask your Ella dealer or the team to confirm which options are available on the specific model and size you are considering.
Is the backrest heated as well as the seat?
The option is offered as a heated seat and backrest together. If a listing mentions only a heated seat, ask the team to confirm exactly what that configuration includes.
