Walk-in tubs with jets, explained with real numbers
Air jets, water jets, combination and microbubble systems: what each one does, what it takes to wire and run, who should skip them, and what the research actually shows. Free tools, published by Aging Safely Baths.
Direct answer: a walk-in tub with jets is a door-entry tub with water jets (a pump, firm aimed massage), air jets (a blower, gentle bubbles all over) or both. Most run on 120 volts but need their own GFCI-protected circuits under NEC 680.71, often two or three. The jets cost about 10¢ a bath to run; heating the fill water costs about $1.31 at the U.S. average electric rate. Water jets need a monthly cleaning flush. The warmth has better research behind it than the jets do, so choose jets for comfort and check with a doctor if you have heart or blood pressure problems.
Four numbers to know before you buy
Each number comes from a published spec sheet, the electrical code or federal energy data, and each tool below lets you swap in your own. If something here does not match the tub you are quoted, trust the spec sheet for that model, and ask us to explain the difference.

Jet systems by the spec sheet
Ella’s Bubbles publishes unusually complete spec sheets, so they make a good yardstick. Aging Safely Baths is an authorized Ella dealer; other brands publish less detail.
| Ella model | Water jets | Air jets | Inline heater | Water with you seated |
|---|---|---|---|---|
| Petite (compact) | 16 jets, 5–7 A pump | 16 jets, 4.5 A, 500 W | 5.5 A, 650 W | 30–50 gal |
| Elite | 16 jets, 5–7 A pump | 16 jets, 6.4 A | 5.5 A, 650 W | 35–55 gal |
| Royal | 16 jets, 5–7 A pump | 15 jets, 4.5 A, 500 W | 6 A, 650 W | 45–65 gal |
| Deluxe | 14 jets, 7 A, 1,000 W | 16 jets, 4.5 A, 500 W | 6 A, 650 W | 60–75 gal |
| Ultimate | 11 seat + 6 foot and calf, two 5 A pumps | 17 jets, 4.5 A, 500 W | 9 A, 1,000 W | 55–85 gal |
| Companion (two seats) | 14 seat + 6 foot and calf, two 7 A pumps | 14 jets, 4.5 A, 500 W | 5.5 A, 650 W | 65–85 gal |
| Escape (two seats) | 18 seat + 8 foot and calf, two 7 A pumps | 18 jets, 4.5 A, 500 W | 5.5 A, 650 W | 85–135 gal |
Source: Ella’s Bubbles spec sheets (Petite, Elite, Royal, Deluxe and Ultimate dealer copies; Escape and Companion PDFs). Every model lists dedicated GFCI-protected 110/120 V lines, an ozone unit on the water side, and an air system that dries its lines after use. Microbubble, where offered, adds a 1 HP, 7.3 A pump.
Three things jump out. Water-jet tubs carry 14 to 26 nozzles, not the hundreds some ads suggest. A two-seat tub has two water pumps, so it needs more circuits. And the inline heater draws as much as a pump; it keeps warm water warm but cannot heat a cold fill.
Air, water or both?
Water jets
A pump recirculates bath water through adjustable nozzles aimed at the back, hips, calves and feet. Firm and targeted. Needs plain water and a monthly flush.
Air jets
A blower pushes warmed air through small jets in the seat and floor. Gentle all over and kind to fragile skin. The lines purge themselves.
Combination
Both systems with separate controls. Best when two people share the tub or you want both feelings. More circuits, more cleaning.
Not sure? The 6-question jet chooser matches a system to where you hurt and how you bathe.
What jets can and cannot do for your health
Warm water eases stiffness, and a Cochrane review found warm-water exercise brings small short-term gains for knee and hip arthritis. A warm bath an hour or two before bed helps many people fall asleep sooner. But we found no controlled trials of jets in a home tub, so treat them as comfort, not treatment. Our research summary rates each claim.
Check with a doctor first if you have heart disease, blood pressure that drops when you stand, diabetes with numb feet, open wounds, or take medicines that make you drowsy. Keep the water at 92 to 100°F and stand up slowly. See who should not use jets for the sources.
What these tubs look like
Paying for a jetted walk-in tub
- Veterans: the VA’s Home Improvements and Structural Alterations (HISA) benefit has a lifetime limit of $6,800 for a service-connected condition, or for any condition if your rating is 50% or higher, and $2,000 otherwise. Projects must be medically justified. Aging Safely Baths explains the steps on its VA HISA grant page.
- Medicare: Original Medicare generally does not pay for walk-in tubs. Some Medicare Advantage plans and state Medicaid waiver programs have helped with home modifications; ask your plan directly.
- Prices: quoted per home, in writing, after a call about your bathroom. See the walk-in tub cost guide on agingsafelybaths.com for how installed prices break down.
How a quote works
- A call. We ask about your bathroom, who will bathe, what aches, and which jets you are leaning toward.
- A written, itemized quote, including the electrical work your tub needs. Take as long as you like.
- Installation if you go ahead, often in one day by factory-certified installers, or supply-only shipping if you have your own plumber and electrician. Supply-only tubs are also sold online at Showers4Less, Aging Safely Baths’ store.
Who publishes this site? Aging Safely Baths, serving families with safer bathing since 2012. We are BBB accredited and sell air, water and combination tubs from Ella’s Bubbles, Hydro Dimensions, Bestbath and Meditub, so we have no reason to push one jet system over another.
Questions people ask
What is a walk-in tub with jets?
A bathtub with a watertight door in the side, so you step in over a low threshold, sit down and then fill it. Jets add massage: water jets use a pump to push bath water through nozzles, and air jets use a blower to push warm air through small holes.
What is the difference between air jets and water jets?
Water jets are fewer, stronger and aimable, good for one sore area, and need a monthly cleaning flush. Air jets are gentle bubbles all over, kinder to fragile skin and easier to keep clean. Combination tubs have both.
How many jets does a walk-in tub have?
On Ella’s Bubbles spec sheets, water-jet systems have 14 to 26 nozzles depending on the model, and air systems 14 to 18 jets. More is not automatically better; placement at your back, calves and feet matters more.
Does a walk-in tub with jets need special wiring?
Yes. NEC 680.71 requires an individual branch circuit with a readily accessible GFCI, and many tubs need one circuit per pump, blower or heater. An Ella Deluxe draws about 18 amps with everything on.
How much does it cost to run the jets?
About 10 cents a bath for a 1,000-watt pump, 500-watt blower and 650-watt heater running 15 minutes each, at the July 2026 U.S. average of 18.31 cents per kWh. Heating a 60-gallon fill with an electric water heater costs about $1.31 more.
Can jets be added to a walk-in tub later?
In practice, no. Pumps, blowers and jet plumbing are built into the shell at the factory, so decide before you order.
Are jetted tubs safe for seniors?
For most, yes, with warm rather than hot water, a short first soak and a slow stand at the end. People with heart disease, blood pressure that drops on standing, numb feet or drowsy medicines should check with a doctor first.
Can I open the door while the tub is full?
No. The water holds the door against its seal, and opening it would flood the floor. You stay seated while the tub drains, so a fast drain and a warm towel help.
