1 Hour 30 MInutes LaStone Therapy is the original Hot Basalt Lava Stone & Cold Marble Stone Massage. Stones are placed on the body and under the body while receiving massage with the warm stones. La Stone is very detoxing as one stroke with a stone is equivalent to 5-10 massage strokes with the hand. While feeling deep relaxation from a La Stone session, most clients have a boost of energy 2-3 days after a session.
