Horse Spa

Thunder Spa

We guarantee that our Thunder Spa is the strongest and sturdiest equine spa available on the market. It’s engineered to operate in the harshest of environments with a holding tank made from stainless steel ensuring quality and reliability. The patented mechanically bonded liner and swing doors are designed for maximum safety for your animals. We have also modernized the user interface, doing away with manual valves in favour of a more user-friendly press-button control system as well as sensors that alert the operator to low water levels, eliminating the chance of air suction.

Why Cold Water Therapy?

Cold has been used as a form of therapy on athletic injuries since the beginning of time. Horsemen have been taking their horse to the therapeutic properties of the sea for as long as horses and man have worked together. More recently the therapies that have been recognized as beneficial for the rehabilitation of human athletes have become available for the equine athlete with impressive results. We now bring the sea to the horse with cold water hydrotherapy spas.

Thunder Spa cold water therapy works using for basic principles; temperature, depth of water, salt concentration and aeration.
• Cold causes cells to requires less oxygen to function so that further cell damage is not caused by a potential lack of oxygen at the injured site.
• Cold reduces the amount of fluid that accumulates at the injured site causing a reduction in swelling.
• Cold numbs therefore reduces pain.
• Water places pressure, the greater the depth of the water, the greater the pressure. Pressure aids in the dispersal of accumulated fluids, thereby reducing swelling.
• High salt concentration replicates the effect of the sea, drawing fluid, reducing inflammation and promoting healing.
• The aeration of the water increases the amount of oxygen in the water which is thought to aid in the healing process. It also provides a massaging action which not only aids in the dispersal of accumulated fluids but produces a relaxing effect on the horse.

Horses stand more quietly in moving water than in still water. Body and mind are healed during the therapy.
