A spa pad should typically be at least 4 -6inches thick to provide adequate support and stability for the hot tub. It is important to ensure that the pad is made of a durable material, such as concrete or compacted gravel, to prevent settling and to evenly distribute the weight of the spa. Additionally, local building codes and the specific requirements of the spa manufacturer should be considered when determining the appropriate thickness.
