If you are considering a swimming pool you may also want to consider adding a spa for even more entertainment. Inground swimming pools can be equipped with many different options and features, one of the most common is a spa. A spa is generally attached to the swimming pool with a small waterfall and seats from 6-9 people depending on size. Most of our spas range from 6-10 feet inside diameter and are raised between 18-24 inches above the pool height. Spas provide a place to relax out of the main pool and also add a nice waterfall to enjoy. Check out these spas from other projects to see if you might want to add one to your swimming pool.
