Changing Facilities, Valuables & Lockers

The changing suite is mixed.

  • Standard: 82cm (32in) high, 23cm (9.5in) wide, 47cm (18.5in) deep
  • Tall: 140cm (55in) high, 23cm (9.5in) wide, 47cm (18.5in) deep

Thermae Bath Spa will not be liable for damage, injury or loss caused to our guests or their belongings. Due to the mineral content of the thermal water, we advise that items of jewellery are kept in a locker whilst bathing.

The Smart Band

The 'SmartBand' which is given to you on arrival at the Spa acts as the key for your locker and registers the times that you enter and exit the Spa. The SmartBand is also the means of ordering food or drink in the Restaurant, which is then payable on exit. Please note there is a £10 charge for the loss of a SmartBand.

Mobile Phones & Cameras

Out of respect for the privacy of all guests and the restful atmosphere which we are trying to promote, neither mobile phones nor cameras are permitted to be used in the Spa. Upon arrival, you will be asked to place your mobile phone inside a lockable pouch and place it inside your locker for the duration of your visit. 

CCTV is in operation in certain public areas of the spa.

Spa Etiquette

Out of respect for the peace and privacy of our guests, we would request that you demonstrate appropriate behaviour, such as maintaining reasonable noise levels and not being too intimate.
