To create the pool we have used Diamond Brite Onyx Plaster. Diamond brite is the finish, and onyx is the color! This finish on a pool is so great because it can take the wear of the chemicals and if looked after properly, it can last up to 30 years. The reason that concrete is so popular is because of the richness in the way it looks, it can’t be cut with a knife, or tear, and ice can not break it!. The outdoor glass around the sides of the area make for great views of the wilderness surrounding the pool!
