What Is a Therapy Package on a Walk-In Tub?

Updated September 2026

A therapy package, sometimes called the jetting package or massage package, is the set of pumps and systems installed under an Ella walk-in tub at order time. The choices are Soaking, Hydro Massage, Air Massage, Air plus Hydro, Hydro plus Independent Foot Massage, Hydro plus Microbubble, and triple combinations on certain models. The package decides the jet count, the deck controls, whether the LED light and in-line heater are included, and how many dedicated electrical lines your electrician runs.

How It Works

The tub shell stays the same whichever package you choose; what changes is the equipment underneath. Hydro adds a water pump with the in-line heater and ozone, plus a push button and intensity dial. Air adds a three-speed blower with Auto Purge. Independent foot massage splits the jets between two pumps so the foot and calf jets can run on their own, and microbubble adds a dedicated pump, pressure vessel and agitator feeding one jet. The LED chromatherapy light comes with every dual and triple package but not with hydro alone. Because jets follow the package rather than the model, spec sheets print jet and electrical lines per package; a Transfer sheet lists 22 hydro jets for the Hydro package and 11 hydro plus 17 air jets for Hydro plus Air, and both are correct. The whole table is in the therapy package inclusions cheat sheet; jet figures are in jet counts by model and package.

Which Ella Models Have It

Every Ella tub is built with a package, even a soaker, and most single-seat models offer the full menu. The ShaK and Big4One ship with the digital-controller Air plus dual Hydro package included, with microbubble optional, and the Deluxe ships as a fixed Air plus Hydro package. The Front Entry has no Hydro plus Foot option and does not offer the LED light with any package. The LayDown tubs take one therapy at a time and have no LED. See therapy package combinations by model and choosing therapies common questions.

What to Know as an Owner

The package cannot be changed after the tub is built, so settle it with your Ella dealer or the team at (800) 480-6850 before production. If a hydro massage feels too strong, turn the intensity dial down; that dial exists to soften it. Care follows the package: hydro tubs get the monthly vinegar flush and a pump inlet cover check, air systems self-clear with Auto Purge, and a soaker needs neither. Keep the schematic that shipped with your tub; it names the package and its circuits. For any jets question on a ticket, the team will first ask which package is on your order, so have your model, serial number and package name ready.

Common Questions

Which therapy packages include the LED chromatherapy light?
Every dual and triple package: Air plus Hydro, Hydro plus Independent Foot, Hydro plus Microbubble and the triples. Hydro alone and the soaker do not include it, and the Front Entry and LayDown tubs do not have it with any package.
Why does my spec sheet list two different jet counts?
Jet tables are printed per therapy package, not per walk-in tub model, so a spec sheet can correctly list different jet counts for the same tub. For example, a Transfer tub with the Hydro package has 22 hydro jets, while the same Transfer tub with the Hydro plus Air package has 11 hydro jets and 17 air jets. To find the correct jet count for your Ella walk-in tub, match the line on your spec sheet to the specific therapy package on your order.
Can I change or upgrade my therapy package after the tub is built?
No, you cannot change or upgrade your therapy package after the walk-in tub is built because the pumps and jets are installed into the tub shell at the factory. The therapy package is fixed once the tub is assembled. If a hydro massage feels too strong, you can turn the intensity dial down, as this dial exists to soften the massage.
What is the difference between a dual and a triple package?
A dual therapy package combines two systems, such as Hydro Massage plus Air Massage. A triple therapy package combines three systems, such as Air Massage plus Hydro Massage plus Microbubble, with each system operating on its own dedicated pump. Triple packages are offered only on certain Ella walk-in tub models.
Does the therapy package change how many electrical circuits I need?
Yes, the therapy package changes how many dedicated electrical circuits you need for your Ella walk-in tub. Each pump in a therapy package plugs into its own dedicated GFCI outlet, so packages with more pumps require more dedicated electrical lines. Your tub's schematic, which shipped with your order, lists the exact count of circuits needed, and the support team can confirm this information for your installer.
