The majority of our tubs come as soaking tubs, perfect for the first step in hydrotherapy, soaking in warm water. For those that want more, may have system options. Add a recirculating pump and heater to a soaking tub for a tub. Then it will not lose water temperature for as long as it is on. Choose air jets for a light skin caress or water jets that provide a deep tissue massage. Micro Bubbles give your skin a real spa treatment. Or have a combination tub that uses multiple systems.
