SAUNA WITH A MATCHING CHANGE / STORAGE AREA
​
In Wandsworth, London, we replaced an existing garden shed sauna with a completely new installation, creating a spacious and modern wellness retreat. The project combined practical functionality with refined design, making the sauna both inviting and easy to maintain.
​
The new structure was carefully prepared, with detailed drawings provided for preparatory works including flooring, external paving, and framing. Once completed, the sauna was built with a robust CLS timber frame, fully insulated, and sealed with a vapour barrier for long-term durability. The interior was finished in premium timber, with floating benches and a bronze glass door elevating the look of the installation.
​
This replacement project demonstrates how a garden shed can be transformed into a full-scale home sauna, providing a professional-grade spa experience within a residential setting.

MATERIALS
​
The sauna interior was clad in smooth, heat-resistant timber chosen for its durability and warm, natural finish. The consistent grain and soft colour tone create a welcoming and calming atmosphere, while maintaining strength under regular use.
​
A bronze glass sauna door was installed, complementing the timber interior with a touch of elegance. The glass brings light into the sauna and connects it visually to the garden setting, while the bronze tint adds privacy and a luxurious finish.
​
The ceiling outside the sauna was finished in the same timber as the sauna interior, ensuring continuity of design and a seamless aesthetic.

FACILITIES​
The sauna features a 2+2 bench configuration, with two lower and two upper floating benches. The floating design eliminates the need for support legs, simplifying cleaning and reinforcing the modern, streamlined look. This generous layout provides ample seating, making the sauna ideal for both individual relaxation and shared use.
​
Concealed LED strip lighting was integrated beneath the benches and along key surfaces to highlight the warm timber tones and add a relaxing glow to the interior.
​
Paving was installed in front of the sauna to match the existing garden finish, creating a neat and cohesive outdoor transition from garden to wellness space.

HEATER
​
The sauna is powered by a Harvia Cilindro Black 9 kW heater, a stylish stone-filled column heater known for its efficient, evenly distributed heat. Its bold design acts as a focal point within the sauna while providing a traditional steam-rich bathing experience.
​
The system is paired with Harvia Xenio Wi-Fi enabled controls, allowing the sauna to be preheated and managed remotely with ease. This modern control solution ensures maximum convenience while maintaining professional-grade reliability.
