Can I Add Air Jets, a Heater or a Heated Seat to My Tub Later?

Updated September 2026

Wondering whether you can add air jets, a heater or a heated seat to your tub later? The short answer is that therapy systems are factory builds and cannot be added after the tub is made, while a heated seat is an option chosen at order time on any standard order. Air jets cannot be added to a hydro only tub, because each therapy package comes with its own dedicated pump, plumbing and switches built into the shell. An in line heater cannot be added to a soaking or air only configuration. Clearance and fixed units are sold as configured and are never modified. The first thing to check is your order, which shows exactly what your tub was built with. The full picture is in customization options and limits.

Likely Causes

  • You want air massage on a tub that was ordered as hydro only.
  • You want extra jets in a specific spot, such as the lumbar area, on a tub already built.
  • You want an in line heater on a soaking or air only tub, which has no hydro loop to heat.
  • You want a heated seat on a tub that was ordered without one.
  • You want three therapies on a smaller tub that only has room for two.

What to Check, in Order

  1. Read your order to confirm the package your tub was built with, then compare it with therapy package combinations by model and the therapy package inclusions cheat sheet.
  2. Understand that air jets, hydro jets, extra jets and microbubble are all factory installed with dedicated pumps, plumbing and switches, so they are not added after the sale.
  3. Note that an in line heater cannot be added to a soaking or air only configuration. On hydro configurations the team confirms from your order whether a heater is already part of your package.
  4. If your tub has not yet been built, tell your Ella dealer or the team now about any therapy or heated seat you want, so it is included in the order. The heated seat and backrest guide explains what that option does.
  5. Remember that some smaller tubs lack room under the shell for Hydro plus Foot plus Air together, so on those models the choice is Hydro plus Air or Hydro plus Foot.
  6. If your tub is a clearance or fixed unit, such as the Deluxe, plan on using it as configured, because those units are never modified.

When to Open a Ticket

If you are unsure what your tub was built with or want to confirm options on an order that has not yet been built, send your order details and a photo of the control cluster if the tub is already installed to your Ella dealer or the team at ellasbubbles.com/support or (800) 480-6850. The team confirms from your order what is included and what can still be chosen.

If you have not ordered yet and want to be sure the heated seat and backrest is part of the configuration you are looking at, including what suffix letters such as HB in a model number do and do not mean, see how to confirm the heated seat and backrest before you order.

Common Questions

Can I add air jets to my hydro only tub?
No, you cannot add air jets to a tub that was built as hydro only. Air massage is a factory build, meaning it comes with its own dedicated pump, plumbing, and switches built into the shell during manufacturing. Therapy systems like air jets cannot be added after the tub is made.
Can I add two jets in the lumbar area after the sale?
No, additional jets, such as two jets in the lumbar area, cannot be added after the tub is built. Jets are drilled and plumbed at the factory as part of the therapy package. You should choose the therapy package with the desired jet layout at the time of your order.
Can a heater be installed on my 2015 tub?
An in-line heater cannot be added to a soaking or air-only configuration because these tubs do not have a hydro loop to heat. If your tub has hydro jets, the Ella's Bubbles team can confirm from your original order whether a heater is already part of your package. Heaters are factory installed as part of specific therapy packages.
Can I retrofit a heated seat to an existing tub?
A heated seat is an option that can be chosen at order time on any standard order. However, clearance and fixed units, such as the Deluxe, are sold as configured and are never modified. If you want a heated seat, you must order it with your tub, or ask the Ella's Bubbles team about your specific tub if it is a clearance or fixed unit.
Can microbubbles be added to the Deluxe?
The Deluxe ships as a fixed Air plus Hydro package with LED and ozone, and fixed units are sold as configured, so microbubble is not added to it. If you want microbubble, choose a model and package that offers it at order time.
Why can hydro, foot and air not all be on my tub?
Some smaller tubs do not have sufficient room under the shell for three pumps and their associated plumbing. This means that on those specific models, the choice is limited to either Hydro plus Air or Hydro plus Foot therapy packages. The combination of Hydro plus Foot plus Air together is not available on these smaller tubs.
