Because of the small size of Plunge Pools, this is a question that comes up a lot.
The answer is yes, it’s technically possible, but definitely not recommended.
There are a lot of factors that are involved in installing an in-ground fiberglass pool, from digging to leveling to plumbing to backfilling to a hundred other things. Your Leisure Pools dealer has professional pool installers on their staff who often have decades of experience in pool installation. They know where and how deep to dig, how to make sure that the pool doesn’t leak and what permits are necessary in your area.
Also, many manufacturers require that you use a certified installer or builder. Not doing so could void the warranties that are offered.
And, while installing a small pool may seem easy, remember that you still need to cut into your pool to install a skimmer, returns and possibly main drains. You need to be sure that your pool allows for clean and safe circulation of water. Your pool professional understands what is required and how to properly set up the plumbing and electrical connections.
When using your plunge pool, there may be opportunities to use additional returns to push out water for additional comfort and display. Another option is to replace those returns with spa jets for an even stronger spray and elevate your hydrotherapy results.
Also remember that your pool should be kept safe. Be sure to discuss how to best accomplish this, whether it be a fence around your yard, or the use of a pool cover or even an automatic pool cover for even greater safety and security.
So while you might be tempted to try to attempt the project on your own, you will definitely be better off letting a professional handle it.
