The greatest choice is to convert your pool into a spa. Because the spa uses the same plumbing and mechanical systems as your pool, installation will be inexpensive. Because of the high temperatures of the water, adding a spa will allow you to utilize your pool beyond the summer. This fall, your pool may be a hot spring. This can be done by installing a heat pump or by using the heat from the sun during the warmer months. Spas are very popular in parts of the United States where swimming pools are not allowed. You can find spas at luxury resorts and private homes. They provide many benefits that regular pools cannot. Spas reduce stress and help people heal from illness. They also offer warm water for washing dishes or cleaning house. A spa does not have to be expensive to build; any type of pool can be converted into a spa. The best part is that you do not need special training to operate one. All you need is some knowledge on how to install piping and electrical wiring and you're set to go. If you want to add additional features such as jets and lighting, these can be purchased separately at stores that sell spa products. Converting an existing pool into a spa is the most affordable option and it does not require special permits. If you would like to add features such as a jacuzzi, waterfall, or sauna, this can be done later without having to replace the pool.
