Home builders often choose our base model (about 4–6 people) as a clean, high-value outdoor feature that fits many backyard footprints. For clients who want a more complete “spa moment,” the Plus model adds a dressing space while keeping the sauna room 4–6 people for everyday use. Electric Narvi heat is usually the easiest for homeowners, while wood-burning can be a standout upgrade that still supports authentic löyly on stones. Exterior color matching, glass and door choices, and dimmable LEDs let you tailor the finish level to the home’s style.
