Just inside the open end of the oven the floor was scooped out so as to make a hole that would hold a bucket or two of water.

These ovens were always built on the banks of a stream, a big spring, or pool of water.

When a patient required a bath, a fire was built near the oven and a pile of stones put upon it.

The cavity at the front was then filled with water.

When the stones were sufficiently heated, the patient would draw himself into the oven; a blanket would be thrown over the open end, and hot stones put into the water until the patient could stand it no longer.
