Royal Massage is proud to offer both hot and cold stone sets for the beginner to the most advanced massage therapist. Most Stone massage therapy has many benefits. In the past few years, it has grown rapidly in popularity. Both hot and cold stone techniques have their own benefits. Our 4pc X-Large set features 4 stones measuring about 4.6 in x 3.3 in x 1.1 in each. Perfect for use in large areas such as the upper arms, legs, and back. They can be used for direct pressure or to protect the therapist's hands. Hot stone massage is not only a relaxing massage method, but it also has many healing properties. The use of hot stones allows a therapist to give a deep, penetrating massage without putting excessive stress on his or her own body. Additionally, the stones will heat the skin, open the pores, and prepare one’s skin to better absorb massage oils. They, therefore, increase the benefits any given oil will provide. The use of massage stones is also a great way to increase circulation in and around the area being massaged. Increased blood flow will help clear out toxins and assist in healing an injured or strained area. Basalt is the ideal material for hot stone massage. The composition of this volcanic rock (high silica and iron content) makes it hold heat longer than most stones. Using a different type of stone may mean that you have to switch stones in and out of the warmer quite often, or they will become too cool for treatment.
