To save space in this home addition, the Endless Pools® Performance model was installed partially in-ground. That allows a 6' depth at one end while still leaving an airy feel under the mezzanine! To conserve heat and minimize humidity, this installation includes Endless Pools' automatic security cover. Hidden below the deck of the wood coping, the cover traps the water and protects the pool with the turn of a key! It also gives the most polished finish!
