The SAWO30 Wall Black heater is perfect for maximizing space and adding a minimalist yet stylish aesthetic. Its capacity to hold more stones in its tall, sleek body ensures it delivers abundant steam and humidity. The SAWO30 Wall also comes with a removable stone spacer, which offers two setup options of (1) faster heating, energy efficiency, and a hotter sauna with the spacer, or (2) room for more stones to generate more steam, milder temperature, and energy savings in a commercial setup without the spacer.
