A standard two-hour spa session at Thermae Bath Spa costs roughly £44-£49, typically more at weekends than on weekdays, giving you access to the open-air rooftop pool, the Minerva Bath and the Wellness Suite. You don't have to book ahead; walk-in sessions are available daily, though arriving early is worth it since entry runs as a virtual queue once the day gets busy. It's an adults-only spa, with a minimum age of 16.
What a two-hour session includes
The standard "Thermae Welcome" session covers the New Royal Bath, the modern part of the complex, and includes a towel and robe for the two hours. That gets you access to three main spaces: the open-air rooftop pool, with views across Bath's skyline and the surrounding hills, by day and lit up at night; the Minerva Bath, the largest of the thermal pools, with air seats and bubbling jets in the naturally warm, mineral-rich water; and the Wellness Suite, a multi-sensory setup combining an infrared room, a celestial relaxation room, an ice chamber and two aroma steam rooms drawing on Roman and Georgian spa traditions. The Springs Café is also accessible during your session for light bites and drinks, charged to the wristband-style SmartBand you're given on arrival and settled when you leave.
Prices and how to book
A two-hour spa session costs roughly £44-£49, and pricing is generally higher on Saturdays and Sundays than on weekdays. Thermae Bath Spa sets its own current prices and these can change, so confirm the exact rate for your chosen day on thermaebathspa.com before you travel. You don't need to buy a voucher or book ahead for a standard session, since walk-in spots are available every day, but Thermae also sells a limited number of pre-bookable sessions if you want a confirmed time slot rather than relying on availability on arrival. Walk-in demand is genuinely high, especially at weekends and in school holidays, and entry operates as a virtual queue once the day's capacity fills up, so turning up earlier in the day gives you a better chance of a same-day slot without a long wait.
Who can visit
Thermae Bath Spa is strictly an adults-only venue, with a minimum age of 16 for all sessions (18 for treatments), so it's not an option for a family day out the way the nearby Roman Baths can be. An accessibility rate is available for guests who need it; details are on Thermae's own access statement, or you can call their reservations line directly on 01225 33 1234 to ask before you book.
Thermae Bath Spa versus the Roman Baths
These are two separate attractions next door to each other, often confused by first-time visitors. The Roman Baths is a historic site and museum: you look at the ancient bathing complex, but the water itself isn't safe to enter. Thermae Bath Spa is the opposite: a modern, working spa where you actually bathe in Bath's natural thermal water, but there's no Roman history on display. If you've only got time or budget for one, our guide to Roman Baths versus Thermae Bath Spa breaks down which one suits what kind of visit, and our Roman Baths guide covers that attraction's current pricing separately.
Making a day of it
A two-hour session pairs naturally with lunch or an early dinner somewhere central, since Thermae sits right in the middle of Bath's old town. If you're staying over, check our where to stay in Bath guide for areas within easy walking distance, and if you're driving in, our honest guide to Bath hotels with on-site parking and the Bath parking guide cover your options, since Thermae itself doesn't have its own car park.
