What type of base is recommended underneath the hot tub?

As a general rule, the hot tub should be placed on a solid, level surface e.g. a concrete base, a wooden terrace, a gravel bed, paving stones, etc. It is inadvisable to set the hot tub directly on the ground due to the risk of uneven weight distribution which can cause the hot tub to sink in and get damaged. Bear in mind that, once filled with water and persons, total weight of the hot tub can exceed 2 tonnes depending on the Skargards model.
