How much space do I need for a sauna?
Many residential saunas start at about 4′ x 6′, but the exact size depends on headroom, bench layout, and how many people you want to seat. We help you size the room for your Happy Valley home.
Most projects start around 4′ x 6′, but exact sizing depends on your layout, ceiling height, and seating needs. Your West Linn space will be measured and right-sized during planning.
