Dedicated Wellness Space, Thoughtfully Designed
The core configuration of the Celtic GS is designed as a self-contained garden gym with an integrated sauna. The layout combines a functional workout area with a private sauna zone, creating a balanced environment for training, recovery and relaxation. Alternative configurations can accommodate additional storage, changing space or a compact shower area, depending on how the space is intended to be used.
The modular structure of Celtic GS allows for precise off-site manufacturing using cross-laminated timber panels, ensuring structural strength, thermal performance and long-term durability. This construction approach supports year-round use while maintaining a controlled internal environment suited to both exercise and heat-based wellness. The result is a flexible, purpose-built space that extends the usability of the garden beyond traditional residential functions.

Working with both private homeowners and developers, Celtio provides a structured process covering design, manufacturing, delivery and installation, ensuring each garden gym with sauna is supplied as a complete, ready-to-use solution.
