Important Installation Requirements

Electrical Supply: The 9kW heater requires a dedicated 40amp power supply. A qualified electrician must install a dedicated circuit from your consumer unit, including a disconnect isolator switch, to ensure safety and compliance.
Timber Maintenance: The sauna is crafted from durable Thermowood. To keep it looking its best and to protect your 5-year wood warranty, the exterior must be treated with a high-quality, clear wood preservative (such as Ronseal Trade Total) immediately after installation.

Why Invest in a Yakia Sauna? Regular sauna sessions provide significant health benefits, including:

Stress Relief: Deep heat helps calm the mind and ease physical tension.
Muscle Recovery: Increased circulation supports faster recovery after exercise.
Deep Detox: The sauna heat encourages sweating, which helps flush out impurities.
Better Sleep: Unwinding in the heat can help prepare your body for a deeper, more restful night.
