A Finnleo custom built Outdoor Sauna will meet your special needs for backyard living. Custom-Cut Outdoor Saunas are perfect for new construction—such as within a pool house—or remodeling an existing backyard structure, such as a shed or unattached garage. A special design or unique location doesn't mean you have to settle for less.

Custom Outdoor Sauna Interior View

By incorporating a Finnleo Custom Sauna within the confines of almost any backyard structure, the options are unlimited. A basic garden shed can be converted to an integral part of a backyard healthy living area, complete with a lot of glass, diffused lighting and can include a multi-purpose changing room. With a Finnleo Custom-Cut Sauna, you can achieve them all. Your ideas, in partnership with Finnleo’s experienced design team, assures the addition of a stunning sauna will fit perfectly into your backyard living area.

A Custom-Cut Outdoor sauna includes the finest materials pre-cut-to-length for your walls and ceiling; the benches are prebuilt and the door is prehung — all for final installation on your framed walls. Simply provide the inside dimensions, the door location and your preference for bench configuration — we'll do the rest. Need design assistance to overcome potential challenges? Contact us. We'll provide free recommendations and C.A.D. drawings.
