Byonz

About

Byonz is a private sauna venue on the edge of Groningen, with Finnish, infrared and wood-fired saunas, a swimming pool, a steam cabin and a hot tub. The space goes to one group at a time, booked by the block, with overnight stays possible. It is modern and adults-only.

Good to know

• Bookable as a private session: rent the room for your group rather than sharing with strangers.
• Hot tub on site: adds a warm-water option between the sauna and the cold plunge for a longer cycle.
• Pool on site: works alongside the sauna for swim-and-sauna sessions or a longer cool-down between rounds.
• Wood-fired heat: softer, heavier löyly than electric, and the smell of the stove is part of the room.
