Yes, hot tubs must be installed on a flat, level surface to ensure that they are stable and safe to use. A hot tub that is not installed on a level surface can be unstable, which can be dangerous for those who use it. In addition, an unlevel hot tub may not function properly, with water that is not evenly distributed and jets that do not work as intended.
There are several types of surfaces that are suitable for hot tub installation, including a SmartDeck, a reinforced deck, a patio, pavers, or a concrete pad.
When choosing a surface for your hot tub, it’s important to consider the weight of the hot tub and the structural requirements of the surface. A hot tub can be very heavy, so it is important to make sure that the surface you choose can support its weight. In addition, it is important to make sure that the surface is level, as an unlevel surface can cause problems with the operation of the hot tub.
