Spa 15 Facilities in Bath

Find your balance

Discover wet and dry areas, unique chill-out spaces and plenty of personality

Our facilities

A luxurious cedar wood hot tub and sauna, to be found in beautiful old exposed stone vaults beneath the pavements, provide wet and dry areas in which to sit back, relax and rediscover that all-important balance.

The Retreat offers a cosy chill-out space, while four treatment rooms are individually designed around bespoke art installations − tapestries, tactile ceramics, handmade socks and a seabed made out of mixed media − to ensure that your Spa 15 experience, like the rest of the No.15 offering, is anything except ordinary.

Shared use of the hot tub and sauna is £20 per person for hotel guests and free of charge when booking a treatment. Non residents may also use these areas for £35 per person or £20 when booked with a treatment. Private hire after 7pm is also available at a charge of £70 for two guests and £120 for up to six guests and Champagne is £8 per glass when pre-booked. 

Pre-booking of these areas is essential, with prices based on 60 minutes.
