A method of fabricating a tank including placing the tank lid on a support surface such that a surface of the lid faces downwardly, affixing first and second sides and first and second ends along and adjacent to a perimeter of the lid on an opposite surface of the lid, affixing a floor onto an edge of the first and second sides and the first and second ends opposite the lid, inverting the lid and the sides and the ends and the floor such that a surface of the floor faces downwardly, and affixing a cover over a hole formed in the floor. The hole in the floor is formed of a size suitable for allowing a human body to extend therethrough. All interior seams between the lid, the sides and the ends are welded internally. Similarly, all interior seams between the floor, the sides and the ends are welded internally. The cover has a surface which is welded solely externally to the floor.
