Between 1760 and 1800 pools or stewponds, possibly created when clay was dug out for bricks, were formalised into a chain and the Cold Bath House was built.
The Cold Bath House is built of brick with a tiled roof and consists of two small rooms. One room has a fireplace set diagonally in one corner. The other room has a small ankle depth pool and an opening for bathing in the large pool outside which is stone lined.
