To obtain an accurate wax construction bite, the wax must be uniformly soft throughout. This is difficult to accomplish without using a thermostatically controlled hot water bath. Our stainless steel hot water bath allows you to dial in the exact temperature. When that temperature is reached an indicator light goes on. This unit is 5” wide x 6 1/2” deep x 4” high – and includes a platform to aid in removal of heated wax.
