Transform your backyard into a fully customized wellness retreat with the Cabin Sauna—designed for compact spaceswithout compromising on performance, comfort, or control.

With its space-efficient footprint, this 4-person sauna fits seamlessly into smaller outdoor areas while delivering a full traditional experience. Inside, the two-tier benching system allows you to naturally move between heat levels, creating a personalized session without constant adjustments. A built-in gravity venting system ensures balanced heat circulation throughout the space, so every seat feels consistently warm and inviting.

What sets this model apart is its advanced Wi-Fi heating system. Powered by the Harvia Spirit Wi-Fi 8kW heater and Xenio CX45 control, you can remotely adjust temperature and settings directly from your smartphone using the MyHarvia app. Preheat your sauna remotely, fine-tune your session with precision, and enjoy effortless control through a sleek wall-mounted touchscreen interface. Crafted in Finland, this system delivers powerful, consistent heat with modern smart control.

Whether you prefer dry heat or steam, simply pour water over the sauna stones to create your ideal environment—promoting circulation, muscle recovery, and deep relaxation.

Designed with ease in mind, the Cabin Sauna features pre-cut, interlocking panels for straightforward assembly with no cutting required. With basic DIY skills, you can have your sauna set up and ready to use in just a few hours.
