How do hot tubs and spas work?
Water is drawn through drains in the footwell and through the skim filter. The water is then pumped through a filter, over a heater and then mixed with air before it is returned through the jets. The jets are often adjustable so you can increase or decrease the water flow and air flow from each jet. Our best hot tubs and spas feature unlimited flexibility to suit every taste from the softest touch to a powerful muscle massage.
