This is Finnish-American country, and private hire here has a longer history behind it than the format has elsewhere. Duluth and Minneapolis hold the city end, with Eagle Harbor out on the shoreline.
Some are wood-fired and some electric, and the plunge is usually part of it. On the northern sites Lake Superior does that job.
In the Twin Cities & the Northland, 7 of the curated saunas fit this cut. See the full the Twin Cities & the Northland region guide for every venue, or keep scrolling for just the private saunas.
Every private sauna in Twin Cities & the Northland
Cedar & Stone Nordic Sauna
$$$Duluth, United States
A floating barge sauna at Pier B on Lake Superior, a wood-fired Finnish cabin with windows over the water. Ladder access takes you straight into the lake. Booked as 90-minute private sessions for small groups, with Lake Superior itself as the cold plunge.
Duluth Family Sauna
$Duluth, United States
A 1920s Finnish steam-bath running continuously in downtown Duluth, the last of its kind in the city. Single-sex private rooms with a wood-bench sauna, a simple shower and a rest area. Affordable, walk-in and family-run, with no spa overlay.
Embrace North
$Minneapolis, United States
A no-frills community contrast-therapy spot in Minneapolis, with three electric Finnish saunas and a large communal cold plunge. The pricing and pace make it an everyday option in the Twin Cities sauna scene, not a destination bathhouse.
Fulton Sauna
$$Minneapolis, United States
A custom cedar sauna in a back garden in south-west Minneapolis, booked privately by the group rather than shared with strangers. Sessions run two hours in the evening, with a warming and changing room and the stove already up to temperature on arrival. Two people minimum, five maximum.
PORTAL Thermaculture
$$$Minneapolis, United States
A modern social sauna club in Minneapolis, built around a wood-fired Finnish sauna and a separate electric cabin. A communal cold plunge and warm benches sit between rounds. Reservation-based 90-minute sessions skew quiet and ritual-focused, not a big spa with food and pools.
Sauna Strong
$Minneapolis, United States
A sauna and recovery club in south-west Minneapolis with a traditional dry sauna, communal and private infrared rooms, red light therapy, cold therapy and an open gym floor. Sauna and red light slots are booked in advance; cold therapy and the gym are walk-in. Drop-ins and packages sit alongside memberships.
Takka Saunas
$$Eagle Harbor, United States
A lakeside Finnish sauna on the Keweenaw Peninsula, with a wood-fired stove and a ladder straight into Lake Superior. The water sits around 44°F. Booked as private 75-minute sessions for small groups, with a small dressing room and outdoor changing.
