Thermae Bath Spa

Britain's only natural thermal spa. The same geothermal spring that fed the Roman Baths still rises at 46°C below Hot Bath Street; Thermae Bath Spa draws on it through a modern glass and Bath stone building opened in 2006. The rooftop pool — open-air, 33°C, looking directly onto the Roman Baths and Bath Abbey — is one of the better urban spa experiences in Britain. Tickets from £40 for two hours. Book in advance.

What to expect

Rooftop pool

The defining feature. An open-air thermal pool on the fourth floor with 360-degree views over Bath's skyline — the Roman Baths and Bath Abbey directly visible. The water is natural geothermal spring at 33–35°C year-round. This is the shot that appears in every piece of Bath tourism photography. In winter with mist over the city, it's one of the better urban spa experiences in Britain.

Minerva Bath (indoor)

The main indoor thermal pool with a circular shape and jets. Ground floor. Uses the same natural spring water as the rooftop. Larger and less crowded than the rooftop, particularly during peak weekend times. The better option for longer soaks without managing the rooftop crowd.

Cross Bath

A separate open-air historic bathing site 2 minutes' walk from the main spa building. The 18th-century Cross Bath is smaller, more intimate, and for adults only. Available for private hire or as part of some Thermae spa packages. Tick box for history: this bath is on the original Roman sacred spring circuit.

Steam rooms and wellness suite

Four themed steam rooms (Celestial Shower, Infrared Room, Herbal Steam Room, Ice Chamber) on floors 2 and 3. The wellness suite is available to all day visitors at no additional charge. The ice chamber is worth using before returning to the rooftop pool.

Spa treatments

Treatment rooms on floors 2 and 3. Massages, facials, body wraps, and the signature Watsu water therapy. Treatments are booked separately and add significantly to the session cost. Book treatments 2–4 weeks ahead in summer. The Watsu treatment (floating-assisted water therapy in the pool) is the signature and most distinct from what other UK spas offer.

Before you go

  • Book in advance: Weekend sessions sell out. Book at least 48 hours ahead; 1–2 weeks for peak summer weekends. The spa website is the only booking channel — there's no phone booking.
  • Best time to visit: The rooftop pool is most atmospheric in winter (misty city views), during rain (you're warm and the views are dramatic), and in the early evening from April to October. The busiest time is Saturday afternoon from 12:00–16:00.
  • Towel and robe: Neither is included in the base entry price. Hire a towel (£5) and robe (£8) at reception, or bring your own. Bring flip-flops for the changing rooms.
  • Mobile phones: Not permitted in pool areas. There are designated photography zones on the rooftop but they are small and often occupied. Leave your phone in the locker.
  • Getting there: Hot Bath Street, Bath BA1 1SJ. 8-minute walk from Bath Spa station. 5-minute walk from the Roman Baths. No car park at the spa; use SouthGate or Charlotte Street car parks.

Stay near Thermae Bath Spa

The Gainsborough Bath Spa (on Beau Street, 3 minutes' walk) is the only Bath hotel with access to its own natural thermal spring pool — guests can use the thermal suite as part of their stay. Otherwise, most Bath city-centre hotels are within 10 minutes' walk.

What is Thermae Bath Spa?
Thermae Bath Spa is Bath's only working spa fed by natural geothermal spring water — the same underground source the Romans used 2,000 years ago. The water rises at 46°C and is cooled to bathing temperature (33–35°C) in the pools. The spa building is a contemporary glass and Bath stone structure adjacent to the original Hot Bath and Cross Bath historic sites. The rooftop pool with views over Bath is the defining feature. It opened in 2006 and is the only spa in Britain where you can bathe in natural thermal spring water.
Do you need to book Thermae Bath Spa in advance?
Yes. Thermae Bath Spa should be booked at least 48 hours in advance, and 1–2 weeks ahead for weekend visits. The spa has timed entry slots to manage capacity; walk-ins are only available if the session is not at capacity, which is rare on weekends from April to September. The rooftop pool has a maximum capacity; when full, guests on lower floors are asked to wait. Online booking at thermaebathspa.com is the only way to guarantee a slot.
Can you see the Roman Baths from the Thermae rooftop pool?
Yes. The rooftop pool at Thermae Bath Spa directly overlooks the Roman Baths and Bath Abbey. The view takes in the Abbey tower, the Roman Baths complex, and the wider city skyline. The two buildings sit adjacent to each other — you're bathing in the same geothermal spring system used by the Romans, with their bathing complex visible directly below. Evening and winter visits in low mist are particularly atmospheric.
What is the difference between Thermae Bath Spa and the Roman Baths?
The Roman Baths is an archaeological site — you visit to see the ancient ruins and museum, but you cannot bathe. The water is the same underground geothermal source but the Roman Baths complex is not a working spa. Thermae Bath Spa is a modern working spa that uses the same spring water — you come here to actually bathe and swim. Many visitors do both in a day: the Roman Baths in the morning (allow 2 hours), then Thermae Bath Spa in the afternoon (allow 3–4 hours).
What should I bring to Thermae Bath Spa?
Bring or hire at the spa: swimwear (required in all pools), towel (£5 hire), robe (£8 hire), flip-flops or pool sandals (recommended for changing rooms). The spa provides complimentary shower products. Lockers hold your belongings during your session. Mobile phones and cameras are not permitted in the pool areas — there are designated photography zones on the rooftop. Jewellery should be left at home; the spring water can discolour some metals.
