The Runnymede on Thames

Waterbabies will love this bright, contemporary spa attached to a modern hotel on the banks of the River Thames. Inside, there’s an 18-metre indoor pool and whirlpool; outside there’s a large pool, only open during the summer. The spa also has a huge eucalyptus-infused steam room and a hot traditional sauna to relax your limbs before enjoying Guinot or ESPA treatments. In the changing rooms, you will find a women’s only sauna with a plunge pool. Great for swimmers and spa-ing with friends.
