Thornton Hall features a four-star hotel with a variety of rooms and suites as well as three options for food and drink including the main hotel restaurant for fine dining, an accompanying bar and the Health Club’s own brasserie. The spa sits within the grounds, including a gym, and a 20-metre pool with a satellite whirlpool, a spa pool, and two outdoor hot tubs with power jets. There is also a hemlock sauna, fibre optic steam room, a snow cave, rasul treatments and a range of face and body therapies. There's also a Hair Spa to complete the experience.
Thornton Hall aims to make the hotel and spa accessible to all. Their accessibility measures include: ground floor rooms - two wet room bedrooms and some ground floor treatment rooms. They do not have any lifts so they request guests let them know about any requirements. Around the spa and hot tubs there are a small number of steps into the changing rooms and into the pool.
