Air Bath vs Whirlpool? The benefits of a BainUltra air tub

At first glance, there doesn’t seem to be much difference between whirlpools and air tubs. Both provide jet massages in a tub. But once you are in the market for one or the other, you will quickly realize that there are some important variances between a whirlpool tub and an air tub. The main distinguishing feature that sets the two apart is the mechanism by which the jets operate. Simply put, a whirlpool shoots jets of water while an air tub uses jets of air. This can have several implications in regards to upkeep, function and personal preference.

The most noticeable difference is the sensation. A whirlpool’s water jets come with the classic, high pressure, deep massaging jets that most people have come to associate with hydrotherapy. An air tub, on the other hand, is a more generalized, effervescent feeling. Instead of a few concentrated jets, the air tub has numerous air jets that shoot millions of massaging bubbles. It’s a gentler sensation, but still highly relaxing. BainUltra, the originator of the air tub, offers many benefits to their “thermomasseur” air bath, including different shaped backrests, heated backrests, and raised seating areas. In addition, BainUltra gives you an infinite number of ways to personalize your massage experience by combining the effects of hydro-thermo massage, chromatherapy, aromatherapy and sound therapy, according to your needs. You can also add any product you desire to the water, control the duration and intensity of the massage, and adjust the temperature of the backrest and headrest.

 The other significant difference between whirlpools and air tubs is the maintenance. Both are relatively simple to clean. For a whirlpool, simply add in a cleaning solution (store bought or homemade) and run the jets for a few minutes. However, due to the up and down slope of the pvc hardness around a tub, standing water and bacterial growth can occur. It’s also important to remember to never run a whirlpool unless it is filled. On the other hand, The BainUltra air injection system ensures full drainage and completely dry air channels. The slope of the air channel and strategic location of the air jets ensure optimal drainage. Any surplus water is pushed out of the velocity pockets by air pressure during the drying cycle, which automatically activates 10 minutes after a session. A powerful 90-second burst of air dries out the air channel completely.

Clean and simple :

  • No standing water
  • Nothing left over from the previous bath
  • Complete peace of mind
