Tahoe Sauna Company · Deck Sauna Plan – 3–4 Person (7x7.5)

Materials & shopping list

Everything you need for the deck sauna build, with the quantities from your plan and a link to where we buy each item. Prices are estimates from when the plan was priced and will drift — check the store before you budget to the dollar. Lumber prices especially move around and vary by store.

Some links on this page are affiliate links. As an Amazon Associate, Tahoe Sauna Company earns from qualifying purchases. It doesn't change your price, and we only list what we'd use on our own builds.
