About this buildout.
The S4N is a round tub in Thermo-Spruce with a dark grey fiberglass liner, so bathers sit facing each other. The stove sits in a stainless steel panel in the tub wall and is fed with firewood from outside, and the chimney rises beside it. The tub holds 304 gallons. The Model S4B option finishes it in black. We confirm the exact configuration and placement with you during the consultation.
When you add an S4N through us, we handle delivery, placement, and coordination of the site work, including the water plan and where the chimney stands. We walk the spot with you first and confirm every detail before anything ships.

“David, the owner, worked with us to get a high quality sauna. David is very responsive, knowledgeable, honest and responsive. He will have your sauna delivered to your home. He will then assemble the sauna and remove all the packaging. I highly recommend purchasing a sauna from Sauna Friend.”
Dennis DonovanFort Collins, CORead it on Google (opens in a new tab) “Sauna Friends were exceptional! They fixed my sauna door, added flashing, and reinstalled my sauna roof. I looked for sauna-specific professionals to do these repairs so I could be confident they'd know what they're doing, and they did.”
Jessmine AndersonColoradoRead it on Google (opens in a new tab) “Worthy of 10 stars! Went above and beyond to ensure we had full understanding in everything: the sauna we purchased, the ordering, delivery, and setup. Absolutely love our sauna and worth every penny. David was incredibly knowledgeable and went out of his way to over-deliver. Highly recommend working with David!”
