The short answer on air tub vs whirlpool tub: an air tub blows warm air through dozens or hundreds of small holes to fill the bath with bubbles, giving a gentle, all-over effervescent feel. A whirlpool tub pulls bath water through a pump and pushes it back out through a handful of larger jets, giving a stronger, targeted massage. Air systems are usually easier to keep clean, especially models with a purge cycle, while whirlpool lines need regular cleaning. Within one tub line, the combination version costs the most. Here is how they compare, with real prices from tubs we carry.
Air tub vs whirlpool tub at a glance
| Air tub (air bath) | Whirlpool tub | |
|---|---|---|
| What moves | Air from a blower, pushed through channels in the floor or walls | Bath water, pulled in by a pump and pushed out through jets |
| Jet count | Many small holes (48 on the Empava air tubs, 264 on a WoodBridge 48 in. air bath) | Fewer, larger jets (12 water jets on the ANZZI Lori) |
| Feel | Gentle, full-body bubbles | Stronger, focused streams on the back, neck and legs |
| Cleaning | Models with a purge cycle clear water from the air channels | Plumbing lines need periodic flushing with a cleaner |
| Bath products | Follow the tub manual | Kohler advises against oils and bubble bath |
How each system works
Both tubs hide plumbing and a motor under the shell. The key difference is what that plumbing carries: a whirlpool moves water, while an air bath moves air.
Air jet tub: blower and pinhole jets
An air jet tub uses a blower to push air through small openings near the floor or lower walls. The Empava 48 in. freestanding air bathtub lists 48 air pinhole jets powered by a 0.5 HP air pump, which Empava describes as a low-pressure massage of thousands of warm bubbles.
Whirlpool tub: pump and hydro jets
A whirlpool draws bath water through an intake, runs it through a pump and returns it through jets you can usually aim or adjust. That recirculation creates the firmer pressure, and it also means bath water can sit in the pipes between uses.
Air bath vs whirlpool: how they feel
An air bath feels fizzy and relaxing, with bubbles rising around your whole body and no single spot getting much pressure. A whirlpool is closer to a massage: the jets push water at your lower back or shoulders. To unwind, air usually suits better; to have sore muscles worked on, a whirlpool is the closer match.
Manufacturers often mention muscle relaxation or pain relief. Treat those as product claims, not medical advice. If you are pregnant, have heart or circulation problems, or are buying a tub for a health condition, check with your doctor about hot water and jet use first.
Are jetted tubs hard to clean?
Whirlpool lines can hold water and residue after each bath. Kohler’s guidance on cleaning a jetted tub recommends cleaning whirlpool jets at least twice a month, and more often if you bathe more than three times a week. The method is simple: fill with warm water to at least 2 inches above the jets, add the recommended cleaner, run the jets for 5 to 10 minutes, then drain.
Air systems avoid most of that because there is no water pump loop. Air baths with a purge cycle blow air through the channels after use to clear leftover water. Kohler’s care and cleaning guide for its BubbleMassage air baths has you drain the bath and run the purge cycle as part of routine cleaning, and clean hard-water deposits from the airjets with a small brush and white vinegar. Look for a purge or dry cycle when you shop.
Bath oils, salts and bubble bath
Kohler advises avoiding bath bombs, oils and bubble baths in jetted tubs because they can build up in the jets. Some makers say otherwise for specific models: the ANZZI Lori listing states the tub is safe to use with aromatic oils and bathing salts and includes an aromatherapy system that releases scent through the air injectors. Always go by your own tub’s manual.
Noise, power and heaters
Noise
Both systems run a motor, a blower or a pump, so neither is silent. Listings note motor placement (center-left on the Empava 48 in., right side on the 59 in.), which helps you keep it away from a shared bedroom wall.
Electrical needs
The Empava 59 in. air bathtub and its 48 in. sibling come with a pre-installed US standard 120V power cord and a UL-certified motor. The WoodBridge BJ400 72 in. whirlpool and air tub lists one dedicated 120V 30 amp breaker. Have a licensed electrician confirm circuit and GFCI protection against the installation manual and your local code.
In-line heaters
The WoodBridge BJ400 has an inline heater set from an LED control panel, and the ANZZI Lori 6 ft. whirlpool and air tub includes a maintenance heater. Both are described as keeping the bath warm for a longer soak without adding more hot water. The Empava 59 in. has no heater listed but uses a double-walled insulated shell.
Cost comparison with real prices
To see the price step for each jet type, compare one tub sold in several versions. MediTub offers its 36 x 60 right drain walk-in tub in four versions with the same shell:
| MediTub 36 x 60 right drain version | Price at the time of writing | Step over soaking |
|---|---|---|
| Soaking (no jets) | $3,950.10 | None |
| Whirlpool jetted | $4,729.73 | $779.63 |
| Air jetted | $5,041.58 | $1,091.48 |
| Whirlpool and air jetted | $5,301.45 | $1,351.35 |
The freestanding tubs we carry cost less than those walk-in versions. Among air tubs, the Empava 48 in. air tub was $1,449.99 and the 59 in. $1,599.99 at the time of writing, while the WoodBridge 48 in. rectangular air bath with 264 air jets and a 47 gallon capacity was $2,417. Combination tubs ranged from the ANZZI Lori ($1,847.99) to the WoodBridge BJ400 ($3,998), so compare features, not just the jet type. Orders of $999 or more ship free by freight.
Whirlpool and air combination tub: worth it?
A whirlpool and air combination tub has both a pump and a blower, so you can run gentle bubbles, targeted jets, or both. The ANZZI Lori pairs 12 water jets with air injectors, powered by a 1 HP pump and a 1 HP air blower, and holds about 53 gallons. The WoodBridge BJ400 lists 6 adjustable body jets and 10 whirlpool bubble jets with a 65 gallon capacity. The tradeoff is cost, a second motor, and whirlpool lines that still need cleaning. Browse more ANZZI tubs to compare shapes and sizes.
Which should you pick?
- Choose an air tub if you want a gentle soak and lower upkeep.
- Choose a whirlpool tub if you want firm, targeted pressure and are happy to clean the lines a couple of times a month.
- Choose a combination tub if two people with different tastes share the bath, or you want both options and the budget allows.

Frequently asked questions
Which is better, an air tub or a whirlpool tub?
Neither suits everyone. Air is softer and easier to keep clean; a whirlpool massages harder but needs regular line cleaning.
Are jetted tubs hard to clean?
Not hard, but whirlpools need routine care: Kohler suggests circulating a cleaner at least twice a month. Air tubs with a purge cycle need less attention.
Can you use bath oils or salts in an air jet tub vs whirlpool?
It depends on the model. Kohler advises against oils and bubble bath in jetted tubs, while ANZZI says the Lori is safe with aromatic oils and bath salts. Follow your manual.
Do jetted tubs need a dedicated circuit?
Some do. The WoodBridge BJ400 lists one dedicated 120V 30 amp breaker, while the Empava air tubs ship with a 120V power cord. An electrician can confirm what your model needs.
