The Earth Spa comprises a cluster of nine buildings, which appear to be floating on ponds. These include four treatment rooms with private outdoor Jacuzzi, two steam rooms, the meditation cave, relaxing area offering fresh juices, and the reception area. The earth domes are designed with openings low to the outside water, allowing refreshing breezes and energy flows to enter the buildings. Openings at the top of each building provide natural ventilation.
The buildings are a design feature created by the Six Senses project team. In Northern Thailand, the buildings have vertical walls, whilst retaining the same cooling system and the chimney-effect.
