An air tub creates thousands of warm bubbles that caress the skin. The bubbles stimulate the skin's light touch receptors, producing an overall calming effect. Shop Air Tubs →
What is an Air Tub?
A blower (motor for an air bathtub) works like a giant hair dryer. It warms the room temperature air by approximately 30° and blows it into the bathtub. Its kind of like when you were a kid and blew through a straw into your soda, producing lots of large and small bubbles. Air tubs differ from a whirlpool in that the
massage is much softer. Take your hands, open-faced and rub them together. This is the massage intensity of an air tub. The intensity can be changed with the control. Turn it down for a "low simmer" or all the way up for a"full boil". Many also have a wave and pulse feature –
amount of air is preset to change according to a pattern. There is more noise with this type of system. It is not the sound of the pump that you here but, a "bubbling & popping sound" that the bubbles make. An Air Tub differs from a Whirlpool in many ways. See Spa Tubs →

Does An Air Jetted Tub Feel Cold?
Often it is said that air tubs can feel cold, or cool down quickly. The air blown through the tub is warm, but it can feel cool on the skin. Let's say you are working outside and you are hot and a bit sweaty. A breeze blows by and even though the breeze is the same temperature as the surrounding air, it gives you the chills. Air on hot, wet skin can cause chilly sensation. Some people are more prone to this than others. If this sensation affects you, an air tub can still be for you - look for a perimeter air system (see air jet location below). The heater on the air blower will warm the room temperature air by about 30 degrees before blowing it into the tub.
Air Tubs with In-line Heaters
Until recently an in-line heater to maintain water temperature was only an option on a whirlpool. Now MTI
, Hydro Systems
and Hydro Massage
offer a 2nd system that includes a pump/heater to keep the temperature consistent. It re-circulates water, like a whirlpool but, instead of white water rapid speed, more like a slow running creek.
As the water is taken from the bath it runs through an in-line heater, then once heated, back into the bath. This heater will keep the temperature of the water within 1 to 2 degrees of what the bath water was poured at, for as long as the bath is on. There are two suction covers - one to pull water out of the bath - the other to put the water back in. This system does take a separate GFCI electrical connection
Features of the Perfect Air Tub
We have found that the most important features when choosing the perfect air bath are:
Tub Size & Installation
Air Jet Placement
Not all tub companies put there air jets in the same location. Some are perimeter systems (just above the tub floor, around the sides of the bathtub), some are across the bottom and some include jets on the back. Some offer an option of perimeter or bottom, some have all. With a perimeter system the air blows horizontally in to the bath. It pushes the water at the bather, the air not hitting the skin directly. When the system is on the bottom, air comes up directly under the bather, bubbles hitting the skin, giving a more vigorous massage. The technical sheet for the bath will give more information on air location.

Bottom Air Jets
Air Jet System
There are two air systems - air injector and air channel. With an air injector each air-port is individually plumbed with a back flow prevention. Air can come into the bath but, water can not flow into the piping system, In the case of a channel system there is a channel built around the bath. Air flows into the channel then into the tub through the air jets. Air and water can enter the channel. Both systems have a purge cycle. About 20 minutes after the tub is turned off, the system restarts blowing air into the tub to remove any water in the system or surrounding the injectors.
The blower is usually located behind the tub's back slant. Access can be through a front skirt, behind the back rest or the back wall (the last two especially if a closet is located there). The technical sheet for each tub will show the location, if the blower fits underneath the tub and if there are optional locations.
Access is needed for any repairs to the bathtub's system. Repairs with the companies we carry are very rare. But, Murphy's Law suggests build access, and it won't be needed, don't and there will be trouble. Recommendations for access size vary among manufacturers:
Hydro Systems 14" x 16", Aquatic 16" x 16" Download the
instructions from the manufacturer's website to see what size you will need.
Remote Mount Blower
It is not recommended to remote the blower unless it is needed to gain
access. In the lines we carry it is difficult to hear the motor over the
sound of water movement, so there is no need to remote the blower to keep noise levels down. On some freestanding baths and combination tubs the
blower will need to be mounted remotely. It is best to keep a remote blower as close to the bath as possible. The further away the blower is, the less air pressure and the cooler the air. There are two things that connect from the blower to the tub: Air Hose & Control Cord.
The list of options can be lengthy. Installation options like skirts, tile flanges and drain are covered in the article Choosing a Bathroom Tub →
