At a glance

Thermal: sauna and therapeutic steam room
Treatments: six rooms including a couples’ suite
Best for: city spa days, hotel stays and treatment-led downtime near King’s Cross
Why visit
The setting is the main differentiator. The pool occupies the former steam-kitchen area of the historic hotel, creating a more atmospheric experience than a standard basement leisure club. It is especially convenient for travellers staying around King’s Cross or arriving by rail.
Pool and thermal facilities
The relaxation pool is maintained at a warm temperature and includes hydro loungers. Sauna, therapeutic steam room and oversized spa loungers create a compact thermal sequence, while the fitness centre uses contemporary Technogym equipment.
Treatments
The treatment programme is organised around personalised journeys using British products, with massage, body and facial care delivered across six treatment rooms, including a couples’ suite. Advance booking is recommended for spa treatments.
How to use the spa
A treatment booking currently includes up to two hours of complimentary pool and fitness-centre access, which makes a half-day visit possible without needing an overnight stay. Hotel guests have separate access arrangements for the pool, sauna and steam room.
Who it suits
Best for travellers who want a polished London spa experience without leaving the centre of the city, especially couples, rail travellers and hotel guests who value atmosphere more than resort-scale facilities.
Good to know
Treatment access, hotel-guest arrangements and pool-use rules can change. The spa is intimate, so pre-booking matters more at busy times.
