Anyone have any recomendations on the best way to create a sundeck on the end on a roman pool? My wife wants to have one of the arches at about 18" deep. The other arch is full depth. I figured pouring solid concrete would work but that is a lot of concrete and I am not sure how to form that up to make a nice radius. Then I though about pouring a slab and front wall, filling with stone and then capping it off. It all sounds good in theory but I dont know how to actually make it happen. Ideas or advice would be appreciated.
