Seasonal Pop-Up
Mtn. Annex · Winthrop
Heat. Steam. Stillness.
Built for slow heat, cold resets, and good company.
Inside, a traditional Finnish wood-fired stove stacked with 800 pounds of stone anchors the room. The fire radiates a steady heat, inviting you to stretch out across the benches.
When water meets the rocks, it releases a rolling löyly. A rich steam fills the space and awakens the senses. Step just outside to reset with a cold bucket dump under the open sky.
It is a slow, powerful experience where the crackle of the fire and the view of the valley come together for the perfect sweat.
Attend select yoga, meditation, or recovery classes at Motive Yoga Co. and get a special $20 rate on a sauna session directly after. First time? Use code MOTIVE10 to get your first post-class sweat for just $10.

Hot sauna and cold exposure are time-tested wellness practices that support both physical recovery and mental wellbeing.
Hot sauna encourages circulation, muscle relaxation, and stress relief by gently raising your heart rate and body temperature. Many people find it helps them unwind, sleep better, and feel more present in their body.
Cold therapy provides a brief, intentional challenge that can reduce soreness, sharpen focus, and boost energy and mood when practiced safely.
Used together, heat and cold create a powerful contrast that many people find deeply restorative, leaving them feeling both relaxed and refreshed. As with any wellness practice, we encourage guests to listen to their bodies and move at their own pace.
Our sauna was built with traditional, sauna-specific materials that perform well in high heat and humidity.
The hot room is constructed entirely from solid alder wood, a classic sauna material known for being naturally low-resin, low-odor, and comfortable under heat. Some of the wood is thermally treated using heat only (no chemicals) to improve stability and durability in sauna conditions.
The interior wood walls are finished with a Finnish sauna wax specifically designed for sauna environments. The sauna is heated with a wood-fired stove and built with proper ventilation to support clean, breathable air.
The result reflects both traditional sauna building practices and modern wellness standards.
We keep the hot room between 170°F and 200°F.
