Nestled in the Hertfordshire countryside, just a short distance from London, Sopwell House offers a tranquil retreat designed for complete relaxation and restoration. At the heart of the experience are two distinct spa offerings - Cottonmill Spa and The Club at Cottonmill - each providing its own unique environment for wellness and escape.

Cottonmill Spa
Cottonmill Spa is the hotel’s main spa facility, offering a contemporary and calming space to unwind. Thoughtfully designed, it features a 14.5-metre swimming pool, a separate children’s pool, Jacuzzi, sauna, steam room, and experience showers. Guests can also enjoy a range of treatment rooms and relaxation areas, creating a well-rounded spa experience suitable for both individuals and groups.

The Club at Cottonmill
The Club at Cottonmill is an exclusive, members’ and residents-only spa, offering a more elevated and immersive wellness experience. Set across indoor and outdoor spaces, it includes hydrotherapy pools, botanical steam rooms and saunas, deep relaxation areas, and landscaped gardens with hot tubs. With its refined design and restricted access, The Club provides a more private and luxurious setting for guests seeking a higher level of tranquillity. Guests staying at Sopwell House have access to Cottonmill Spa facilities from 3:00 p.m. on the day of arrival until 11:00 a.m. on the day of departure. Access to The Club at Cottonmill is subject to room category or package inclusion.
