The "Shell Spa," designed by Lance Jost, is 15" across and is made of a variety of marbles and
some pink onyx. It is basically flat but for the sake of safety there is a slight
cant to the pieces thus providing "wet foot purchase" upon emergence.
The spa overlooks the Pacific Ocean in Dana Point, California.
All the pieces were entirely cut and fit by the hands of Paul RW Anthony,
not by a water jet or laser cutting machine.
