Air Tubs with Bubble Hydrotherapy
Air tubs deliver a gentle, effervescent massage by pushing warmed air through dozens of pinhole jets in the tub shell — a fundamentally different experience from a whirlpool tub, which recirculates the bathwater itself. The result is a softer, full-body bubble sensation that works with bath salts, oils, and bubble bath without damaging internal plumbing.
Because the air channels are sealed and self-draining, an air bath stays cleaner with far less maintenance than a jetted system. Most models include an automatic purge cycle that runs 20–30 minutes after the bath drains, blowing residual moisture out of the channels to prevent any standing water inside the tub shell.

Frequently Asked Questions
Can you use bath salts and bubble bath in an air tub?
Yes — this is one of the main advantages of an air bath over a whirlpool. Because air tubs do not recirculate the bathwater, salts, oils, and bubble bath never enter internal plumbing. A whirlpool would clog or damage the recirculation pump, but an air system simply pushes warm air through sealed channels that never contact the additives.
How loud is an air tub compared to a whirlpool?
Air tubs are noticeably quieter than whirlpools. A whirlpool pump moves several gallons per minute and produces a steady mechanical hum around 65–70 dB. An air bath blower runs closer to 55–60 dB — about the level of normal conversation — and the sound is a softer rush rather than a motor drone. Variable-speed blowers let you dial back the noise further on low settings.
What electrical requirements does an air bath need?
An air tub requires a dedicated 20-amp GFCI-protected circuit for the blower, and a separate circuit if the model includes an in-line water heater or chromotherapy lights. The blower must be accessible for service — plan for a removable skirt panel on alcove installs, or a hinged access door in the surround for drop-in and freestanding models. Local code may also require a bonding wire to the tub frame.
Do air tubs need maintenance like whirlpool tubs?
Far less. A whirlpool needs monthly flushing to clear biofilm from recirculation lines. An air tub's channels carry only air, and the automatic purge cycle blows out residual moisture after each bath. Routine care is limited to wiping the tub surface and occasionally running the blower with the tub empty to clear any dust from the air injectors.
Does an air bath keep water warm during a long soak?
Only if it has a heated blower. A standard ambient-air blower actually cools the bathwater faster than a still soak, because room-temperature air is being pushed through hot water. Models with an in-line air heater (typically 400–500 watts) warm the air before injection and maintain water temperature for 30–45 minute soaks. Look for this feature if you take long baths.
