A water table is a fairly simple design, usually consisting of a complete tub that has some kind of slat supports mounted inside it to the walls. The water doesn't have to be any deeper then 4", usually we recommend having the slats up off the bottom of the tub in order to allow water and air passage underneath the slats to keep the water level even. Keep in mind water is heavy, and on a 5'x10' table can amount up to a serious weight addition. Usually with the kit, you want to build the tub into the frame, adding some support feet down the water table to keep from bowing or bending.
