The spring is now housed in 18th-century buildings, designed by architects John Wood, the Elder and John Wood, the Younger, father and son. Visitors drank the waters in the Grand Pump Room, a neo-classical salon which remains in use, both for taking the waters and for social functions. Victorian expansion of the baths complex followed the neo-classical tradition established by the Woods. In 1810 the hot springs failed and William Smith opened up the Hot Bath Spring to the bottom, where he found that the spring had not failed but had flowed into a new channel. Smith restored the water to its original course.
