The Glass House Retreat

The Glass House Retreat is a purpose-built residential wellness retreat and spa on Harrow Road in Bulphan, Essex. Its current 2026 booking and FAQ pages confirm stays from two to 21 nights, guest rooms, a pool, gym, spa, fitness and mindfulness classes, communal spaces and three meals a day.

All standard stays include facility and class access, while spa treatments and one-night breaks have separate inventory. The two live marketplace programmes describe six-day and 22-day detox formats. Compare those offers with the current first-party stay for room, diet, classes, treatments, screening, inclusions and operator before paying.

Holistic or digital detox, diet, fitness, spa and cryotherapy language does not establish a medical effect or lasting health change. Whole-body cryotherapy has unconfirmed benefits and distinct risks; the venue requires a health assessment and disclaimer. Discuss restrictive diets, strenuous exercise, cryotherapy and treatment suitability with an independent clinician. Current terms require full payment and more than 30 days’ notice to move or cancel without forfeiting the booking, apart from the stated fee.
