This pool is about 20 x 40, and the spa is about a 10' diameter. Pool features 360 degree perimeter overflow, with 75% of that as a slot overflow to the patio, and one 40' length is a vanishing edge, shown in another of the images on this project. The dark tile shown is a metallic glass mosaic. Let me know if you'd like me to get you a quote. contact email is amy@alpentile.com
