A Finnleo Permanently-Installed Sauna will meet your special needs. Custom saunas are perfect for new construction or remodeling: residences, hotels, corporate fitness centers, health clubs, apartment buildings. A special design or unique location doesn't mean you have to settle for less.

The options are unlimited — innovative use of glass windows and doors, unusual angles, unique bench configurations. With a Finnleo Permanently-Installed Sauna, you can achieve them all. Your design, in partnership with Finnleo experience and quality, assures unmatched form and function. If you can design it, we can build it.

We'll pre-cut the finest materials for your walls and ceiling, we'll pre-build the benches and door — 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.
