Soothing and relaxing are just two of the words people use to describe their feelings after soaking in a hot tub or spa and it's easier than ever to reap those benefits by using a portable hot tub spa.

First, examine the difference between a hot tub and a spa, which other than its construction, is minimal. A spa was made of plastic or some other heavy-duty plastic. A hot tub was generally made of wood, such as cedar or redwood, but they were both fitted with pumps and water jets and promoted relaxation.

Today's combination of a portable hot tub spa requires little in the way of installation. All that is required is a flat surface strong enough to support the unit when filled with water, an electric outlet to provide 50- amp service and a garden hose. With these three things you can be soaking in swirling, soothing water in just a few hours.

Many people don't appreciate sitting in warm water outside and there are many different portable hot tub spas that can be installed indoors. However, to fit through a door there may be a sacrifice of depth and overall size. Most portable hot tub spas come with a lockable cover and are well insulated providing comfortable use outside even in the coldest months.

Always Consider Safety First

As with any appliance combining water and electricity, there is always a danger of shock. Any electrical connections needed for a portable hot tub spa should be done by a qualified individual. Many communities mandate electricity be hooked-up only by a licensed electrician.

Additionally, due to the heat and depth of the water, children should never be allowed near the portable hot tub spa without the direct supervision of an adult. The lockable cover, which comes with almost every portable hot tub spa should be in place when not in use.

On average, if the portable hot tub spa is fitted with a quality water filter system, the water should not have to be changed more than three or four times a year. Chemical testing equipment is generally reliable and will inform you when it's time to change and water and the filters.

The cost of operating a portable hot tub spa depends largely on how often it is used and cost of electricity in the specific geographical area. On average, electrical costs will be between $15 and $35 per month, depending on location. A portable hot tub spa installed indoors may cost less for monthly operation.
