This East Hampton 20×40 gunite pool installation with silver marbledust has slate tile, automatic deep heat, and saltwater sanitation. It is a very classic Hamptons look. Builder Patrick Kenney of Southampton installed this gunite pool and patio. The patio and retaining wall are constructed using a “Blue Ice”, a bluestone material imported from India. This stone stays cooler than most other stones and has a more natural, rugged finish to it.
