Geothermal energy raises the water temperature here to between . Under pressure, the heated water rises along fissures and faults in the limestone, until it bubbles up from the ground into the baths. This process is similar to an

Bath and North East Somerset Council, who monitor pressure, temperature and flow rates. The thermal waters contain sodium, calcium, chloride and sulphate ions in high concentrations.
The Roman Baths are no longer used for bathing. In October 1978, a young girl swimming in the restored Roman Bath with the Bath Dolphins, a local swimming club, contracted
naegleriasis and died, leading to the closure of the bath for several years. Tests showed ''
Naegleria fowleri'', a deadly pathogen, in the water. The newly constructed
Thermae Bath Spa nearby, and the refurbished
Cross Bath, allow modern-day bathers to experience the waters via a series of more recently drilled boreholes.

Post-Roman use
The baths have been modified on several occasions, including the 12th century, when
John of Tours built a curative bath over the King's Spring reservoir, and the 16th century, when the city corporation built a new bath (Queen's Bath) to the south of the spring.

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
Neoclassical salon which remains in use, both for taking the waters and for social functions.
Victorian expansion of the baths complex followed the Neoclassical tradition established by the Woods. In 1810, the hot springs were thought to have 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.
The visitor entrance is via an 1897 concert hall by J. M. Brydon. It is an eastward continuation of the Grand Pump Room, with a glass-domed centre and single-storey radiused corner. The Grand Pump Room was begun in 1789 by
Thomas Baldwin. He resigned in 1791 and
John Palmer continued the scheme through to completion in 1799.
