You'll still need framing lumber, insulation, something to finish the outside walls, and an electrician to run the heater circuit. If your room doesn't match one of the sizes above, we can build a custom package for almost any space.

Before You Order

Plan these key details before choosing and ordering your DIY sauna package.

Rough frame size

Order by Your Rough Frame Size

Measure the rough framing and round up to the next package size. For example, if your room is framed at 6'5" x 5'9", order the 6' x 7' package.

Plan the heater circuit

Plan the Heater Circuit

The heater needs its own circuit from your electrical panel, and the bigger the heater, the bigger the breaker. Make sure your panel has room before you settle on a size, and have a licensed electrician pick the wire and breaker from the heater manual. If you go with a digital controller mounted outside the sauna, allow for a little extra wiring.

Keep the ceiling at 7 feet

Keep the Ceiling at 7 Feet

Our cedar comes in 7 foot boards that run vertically, floor to ceiling. Heat rises, so a ceiling at 7 feet or lower keeps the heat down at bench level where you’re sitting, and the sauna costs less to run. If your room has 8 foot ceilings, frame a drop ceiling at 7 feet.

Start from the studs

Start from the Studs

Build your sauna on bare studs. Never put it over drywall, because drywall soaks up moisture behind the cedar and can grow mold. You can finish the outside walls however you like, with drywall to match the room or with cedar.

Western Red Cedar

Why We Only Use Western Red Cedar

People build saunas out of pine, aspen, hemlock and cedar. We only sell Western Red Cedar. It holds its shape through years of heat and steam, it resists rot, and it smells the way a sauna should. Whatever wood you use, avoid knotty boards, which can warp and twist, and cheap hemlock.

Tools you will need

Tools You Will Need

A table saw or circular saw, a level and a drill will get you through it. If you’d rather not take on the carpentry, have a look at our pre-built indoor sauna kits.

Long-Lasting
Premium Cedar

Grade A Western Red Cedar is used throughout our wooden saunas for its natural beauty, distinctive aroma and exceptional performance. Naturally resistant to rot and valued for its high insulation properties, cedar is an ideal material for the heat and moisture of a sauna environment. Sustainable, durable and beautiful, it has been a trusted choice for generations.

Grade A Cedar

Grade A Cedar

Northern Lights uses Grade A or #2 or better cedar for its wooden saunas, selected for its tight grain pattern and absence of knots.

Naturally Rot Resistant Cedar

Naturally Rot Resistant

Cedar’s natural oils help protect the wood against rot and decay, contributing to a long-lasting sauna with minimal maintenance.

High Insulation Value

High Insulation Value

Cedar’s fibrous structure contains tiny air pockets that give it one of the highest insulation values among common woods.

Sustainably Harvested Cedar

Sustainably Harvested

Cedar is sourced from forests that follow strict reforestation practices to help maintain healthy forests for future generations.

Vertical Cedar Installation

Vertical Installation for a Cleaner Finish

Our DIY sauna packages include 7' tongue-and-groove Western Red Cedar boards designed for vertical installation. Running the cedar vertically creates a clean, streamlined appearance and helps reduce the visual breaks that can occur with random-length horizontal boards.

Choose How to Heat Your Sauna

Do you want the higher temperatures and added humidity of steam in your DIY sauna room, or do you prefer the lower, dry heat of an infrared sauna? We have you covered! Choose any of our DIY sauna rooms with either a traditional electric sauna heater or infrared sauna heater panels.

Electric Sauna Heater

Electric sauna heater

Experience traditional sauna heat with a powerful electric heater designed for both dry heat and steam. Reaching temperatures of 150 to 200 degrees F, the stainless-steel heater uses sauna rocks to create intense, even heat. Add water to the rocks whenever you want to introduce steam and extra humidity for the classic sauna experience.

Infrared Sauna Heater

Infrared sauna heater

Enjoy a gentler sauna experience with carbon-fiber infrared heater panels that warm your body directly rather than heating the surrounding air. Infrared operates at a lower, dry temperature while still encouraging a deep sweat. The easy-to-install panels are available with digital control options and can be sized to suit your DIY sauna room.

DIY Sauna Kits FAQ

How much does a DIY sauna kit cost?

Our DIY sauna kits run from $5,870 for a 4 x 4 room with a 4 kW heater to $9,900 for an 8 x 8 room with a 9 kW heater, in Canadian dollars (about $4,150 to $7,000 US). That price covers everything inside the sauna. You get the cedar for the walls and ceiling, the benches, a heater with rocks, an insulated cedar door, two vapor proof lights, foil vapor barrier, a vent kit, a heater guard and floor tiles. You still budget for framing, insulation, the outside wall finish and an electrician.

What size DIY sauna kit should I order?

Measure the rough framing of your room and round up to the next size we sell. A room framed at 6 feet 5 inches by 5 feet 9 inches takes our 6 x 7 package. We have 11 standard sizes from 4 x 4 to 8 x 8, each with the heater matched to the room volume, and we can put together a custom package in the 3D Sauna Designer if none of them fit.

How high should a DIY sauna ceiling be?

Seven feet or lower. Heat rises, so a low ceiling keeps the heat at bench height, and the room heats faster and costs less to run. Our cedar boards are 7 feet long and run vertically from floor to ceiling for exactly this reason. If your room has 8 foot ceilings, frame a drop ceiling at 7 feet before the kit goes in.

Can I build a DIY sauna in a basement, garage or shed?

Yes, as long as the space is framed and insulated and has its own electrical circuit for the heater. Start from bare studs and never build over existing drywall, because it traps moisture behind the cedar and can grow mold. Insulate any wall that faces outside or an unheated space, and give the floor a surface that sheds water, such as tile or sealed concrete.

What do I need to supply for a DIY sauna kit?

The framed and insulated room, the electrical rough in for the heater, controller and lights, the finish for the outside walls, and basic tools such as a table saw or circular saw, a level and a drill. We supply everything that goes inside the sauna, plus full installation instructions. If you would rather not do the carpentry, our pre built indoor sauna kits come as complete rooms.

Can I choose an infrared heater instead of an electric heater?

Yes. You can order any DIY package with a traditional stainless steel heater and rocks, which reaches 150 to 200 degrees Fahrenheit and gives you steam when you pour water on the rocks, or with carbon fiber infrared panels, which give a lower, dry heat and warm your body directly. Both can be run from a digital controller, and the electric heater has a Wi-Fi option.

What electrical service does the sauna heater need?

Your heater needs its own dedicated 240 volt circuit from the panel, and larger heaters need larger breakers. Check that your panel has space before you choose a size, and have a licensed electrician size the wire and breaker from the heater's installation manual. Run the wiring while the framing is open, before the insulation and foil go on, and plan a little extra wire if the controller mounts outside the room.

How long does it take to install a DIY sauna kit?

Most customers finish in two to four weekends. The framing, electrical rough in, insulation and foil come first, then the cedar boards, benches, heater, heater guard and door, 13 steps in all. The electrician's visit and inspection add waiting time between stages, so book them early. Run the heater on high for 30 to 45 minutes with the door and vents open before the first real session.

Why Us?

Our DIY sauna kits combine premium materials, thoughtful design and expert support to help you create a sauna built for lasting performance.

Stainless Steel Large-Capacity Rock Heaters

Enjoy traditional sauna heat with a stainless steel, large-capacity rock heater built for lasting performance. With no painted metal used, the heater provides a clean, durable design while holding plenty of sauna stones for an authentic sauna experience.

Fully Insulated Door with Double-Pane Glass

Our sauna doors are fully insulated with double-pane glass, helping retain heat while providing a premium finished appearance. The insulated construction complements the efficiency of your complete sauna room.
