The NorthStar Series is designed to handle the real world — from chilly basements to snowy backyards. Whether you’re installing indoors or outdoors, these saunas are built with durable materials and timeless Nordic style. There are two main differences between the indoor and outdoor series – the roof and the floor.
Each model is prebuilt for easy installation but finished with high-end details like clear cedar interiors, LED lighting, and Finnleo electric heaters with Wi-Fi Controls. It’s serious sauna quality made simple.
Versatile. Durable. Made to perform in any climate.

The Designer Series blends luxury design with the deep heat of a traditional sauna. Each model is pre-engineered and fully loaded — think full-glass fronts, stunning woodwork, and seamless benches. It’s an upgrade in both looks and performance.

Available in a wide range of sizes, layouts and other custom options, they’re ideal for homes, cabins, and fitness rooms alike.

A modular sauna is comes built in pre-fabricated panels. The panels connect together to form a freestanding sauna.
A big advantage of the modular sauna is that it can be installed and taken down.
Here’s a video on how to install a Finnleo Euro traditional outdoor sauna.

The traditional Finnish sauna is known for high heat (up to 194 degrees Fahrenheit, the max temperature allowed in the US with an electric sauna heater) and the blast of steam felt from pouring water on the hot rocks.
With a traditional sauna you have the option of wood-burning stoves (outdoor only) and electric heaters. Electric heaters offer a softer heat and are more convenient (especially paired with an SL2 control) whereas the wood burning stove offers a hotter, dryer heat but takes longer to heat up and requires more maintenance.
The traditional sauna is relaxing and help you unwind. The heat and steam cause you to sweat which helps with detoxification. Saunas help with relaxation – physically.
Visit our Sauna Showroom to try a traditional sauna before you buy! We are open weekdays from 8AM to 5PM. View our Google Business Profile for all updated hours. Call (612) 505-9700 beforehand so we can warm a sauna up for you!
While we offer wood-fired traditional saunas, we also realize the convenience of the Wi-Fi Control is nice to have. We build and offer both.
The Finnleo Designer SL2 comes with the SaunaLogic2 Control—a sleek, modern touchscreen that puts your sauna settings right at your fingertips. And the best part? It’s Wi-Fi enabled, so you can control your sauna from anywhere using your smartphone or tablet.
The traditional Finnish sauna is a place of gathering. Where families come together to relax, unwind, and share stories of times past.
We were fortunate to grow up using saunas on a daily basis and to this day, we use our own traditional saunas 365 days a year. Our team is passionate about sharing this experience with you and we would be thrilled at the opportunity to work with you in building your own traditional sauna in your space.
We build saunas the way they should be built—with Finnish expertise and Minnesota craftsmanship.

Traditional saunas use a heater (electric or wood-fired) to warm the air inside the room, which then heats your body. Infrared saunas use light waves to heat your body directly without warming the air as much.
Traditional saunas usually run between 160°F and 200°F and offer löyly — the steamy burst you get when you pour water over hot rocks. This is a key part of the Finnish sauna experience. Infrared saunas operate at lower temperatures (around 120°F–150°F) and don’t provide steam.
If you’re looking for a classic, high-heat, full-body sweat with the option of steam, a traditional sauna is the way to go.
We offer three main types of traditional saunas:
Custom-Built Saunas – Fully tailored to your space and preferences. Indoor or outdoor. We handle the design and walk you through the whole process.
Modular (Prebuilt) Saunas – Delivered to your location, ready to use. Great for those who want a high-quality sauna with minimal install effort.
DIY Sauna Kits – You handle the install. We supply everything you need: pre-cut wood, benches, lighting, heater, and instructions.
We also offer wood-burning and electric heater options, multiple wood types, and flexible sizes.
Most traditional saunas heat up in about 30–45 minutes depending on the size, insulation, and type of heater:
Electric heaters: Usually reach 170–190°F in 30–40 minutes.
Wood-burning heaters: May take 45 minutes or more, especially in winter.
Well-insulated saunas heat faster and hold heat better. A tight-fitting door and good ventilation are also key.
Yes — we install indoor traditional saunas all the time. They work great in:
Basements
Spare rooms
Home gyms
Bathrooms or near showers
You’ll need proper ventilation and access to a 240V power source (for electric heaters). We’ll walk you through every step to ensure it’s a perfect fit.
We offer several sauna-grade softwoods that don’t splinter or overheat, including:
Clear Western Red Cedar – Aromatic, beautiful, and naturally rot-resistant.
Knotty Cedar – Rustic and cost-effective.
Thermo-Aspen – Heat-treated and modern-looking with a smooth finish.
Nordic Spruce / Abachi – Traditional, clean, and light in color.
Hemlock, Alder, Aspen – Great options depending on your style and budget.
We help you choose the best wood for your environment and aesthetic.
Saunas are surprisingly low maintenance. Here’s what we recommend:
After each use: Leave the door open to let it dry. Wipe down benches if needed.
Monthly: Check for loose boards, tighten screws, inspect the heater and rocks. Clean benches/ backrests with a natural cleaner that is safe to use on wood.
Yearly: Replace sauna rocks if they’ve cracked or crumbled. Wipe heater down ocassionally (not while on, obviously).
Avoid using harsh cleaners or finishing the wood — let it breathe naturally.
Because we don’t just sell saunas — we live and breathe them. Most of our team grew up with saunas in our homes. We’ve built hundreds of saunas across Minnesota and beyond, and we know what makes a great one last.
