Most spa and hot tub owners like to use their tub all year round. In fact, many people enjoy the relaxing warmth of a hot tub or spa the most, during the cold winter months. However, if you're not one of those types and want to shut your hot tub down during the coldest months of the year, it is necessary that special precautions are taken to make sure that the freezing weather does not damage your hot tub or equipment.
