Boutique resorts often choose the Plus model because the dressing space creates a more “spa-like” arrival while the sauna room stays an intimate 4–6 people. If you’re running a busier wellness program, the Max model (about 8–10) can better support multiple bookings without long waits. Electric Narvi heat tends to fit predictable service windows, while wood-burning can become a signature ritual without losing authentic löyly. Many properties refine the look with panoramic or large windows, dimmable LEDs under the bench, and coordinated interior wall and ceiling finishes that match the brand.
