Before you set up your own portable hot tub, you need to consider exactly where you are going to put it. It has to be a location that combines easy access to your water supply, a power source for the air pump, and a sturdy, level surface.

Always be careful what’s underneath your hot tub, do not place it directly on surfaces which might damage it!

A good surface underneath your tub is essential if you are to have a spa-worthy experience. These portable tubs have sturdy sides, whether inflatable or otherwise, but their collapsible, foldable bottoms need firm support.

Stay Away from Slopes

First and foremost, the area on which you place your hot tub needs to be completely flat. If you place it on a surface with even a slight slope, the tub’s structural integrity will be compromised, and it is likely that it will collapse if filled with enough water.

To keep this from happening, pay close attention when you fill the tub. If you notice that water starts to flow more to one side, or if the walls start to bulge in a certain direction, you will need to move the tub to another location.

Firm Surface under the spa

Firm is the Way to Go

In addition to being level, the surface beneath an inflatable hot tub must also be sturdy and firm. Once filled with water, the tub will weigh quite a lot, and this weight will shift around as people get in and out of the tub. You should thus avoid muddy or sandy surfaces that might not provide the support an inflatable tub needs. Opt for placing your tub on the pavement, or a concrete deck.

Consider Water Drainage

Water drainage is another important consideration. Splashing will happen when people use the tub, even if it’s unintentional, and you need to be able to deal with spills with minimum fuss. You also wouldn't want to have some difficulty when the time comes to empty the tub. For this reason, it is usually best to keep your tub on a surface where water drains easily.

This usually means setting up your portable hot tub outdoors, but an indoor area that meets this requirement will also be suitable. If you believe your hot tub is leaking check out how to find the leak.

Use a Mat for Additional Protection

Whatever surface you settle on, it is best practice to lay a cloth or ground mat underneath the portable hot tub. In addition to protecting the bottom of the tub, this will also minimize water damage to the surface it is on.
