WHAT WE LIKE

  • Traditional outdoor cedar sauna experience without building an entire structure
  • Kit design quickly builds a sauna indoors or out
  • Great for remote locations
  • More likely to have a wood-fired sauna heater
  • Panels are pre-insulated with fiberglass insulation and foil vapor barrier
  • Kit sizes: 4' x 4' – 8' x 12'

NOTEWORTHY

  • Prefab sauna kits can be disassembled and moved to a new location
  • Easy construction. This sauna is not really "built" as much as erected

Prefab modular sauna kit is composed of pre-built wall sections (or panels) ready to screw together, quickly making a sturdy freestanding sauna room indoors or outdoors

SITUATION: You want a sauna outdoors, or if indoors you'd rather not endure construction in a spare room, or you may want a sauna kit you can relocate, or your sauna location is in the woods. DIY assembly time: 1/2 day, excluding base prep work

  1. Sauna kit starts as a wooden frame over the base
  2. The panels are screwed together which form the sauna room walls. Each panel is 6'4"H x 4"D x Width is flexible and depends on your site's needs, but usually 2' or more.
  3. Add the sauna door – which is part of a wall panel
  4. Pre-built ceilng panels completely enclose the sauna, so interior height is 6'4", but can be made taller. If outdoors, add the sauna roof.
  5. Next, you'll need to wire for your sauna heater. A conduit planned through the panel makes it easy to push your wire through. Or your electrician can just drill a hole. Mount or set your heater. Add your benches and you're ready to take a sauna.

Indoor prefab sauna kits are usually placed in a larger room, basement, cabin or sometimes under an outside shelter. This sauna kit can be erected indoors or outdoors, and can be taken down and moved (in about a half-day). If you're wanting a stand-alone outdoor sauna, then we include an sauna roof kit.

Outdoor prefab sauna kits should be erected on a suitable base, such as, pressure-treated wood, cement, pavers or tile. If you're building this kit indoors, then any non-permeable base will work. Tile or vinyl are common. Or if you have an outdoor shelter, then you're fine with just the ceiling panels. Sauna roof kits do have space for more insulation, if desired. See how to build a prefab sauna kit outdoors.

Many picture an outdoor sauna experience as a healthy sweat next to a wood-fired sauna heater followed by an invigorating cold plunge in the lake. If you picture'd that too, then the outdoor prefab modular sauna kit is the best fit for a traditional sauna experience.

WHAT WE LIKE

  • Love the convenience of an indoor home sauna. You'll find you're taking more saunas
  • Indoor saunas often have remote controls, so your sauna turns on automatically after work
  • Custom-cut boards will finish a sauna room quickly
  • Love the smell of cedar
  • Kit sizes: 3' x 5' – 12' x 12'+

NOTEWORTHY

  • An indoor sauna can NOT be relocated, but it can improve the appeal and value of your home
  • Lower room's ceiling to 6'8"- 7'4" ideally

Precut sauna kit is composed of pre-cut and custom-cut cedar boards. This kit basically lines the walls of an existing closet or room with cedar.

SITUATION: You're converting a framed closet, a shed or a spare room in your house, spa, resort or other facility into a sauna room. DIY construction time: 2-4 days, excluding room prep work.

  1. Prep work: If your closet or room has drywall now, you'll demo the room down to the studs. Flooring should be a non-permeable material.
  2. Plan for location of heater and power source, vents, lights, and bench layout.
  3. Wire the room for electricity, and for your heater's requirements.
  4. Insulate with fiberglass insulation and a foil vapor barrier.
  5. Nail the "pre-cut / custom-cut" cedar boards to the length of your ceiling and walls, thus lining the sauna room with cedar. Normally, cedar paneling is clad horizontally.

Continue reading our step-by-step article on converting a room into a sauna with a precut sauna kit, How to Build a Sauna | Convert a Room, and watch our DIY Precut Sauna Videos.

To order this kit, you'd need to measure your room's walls. Download the Precut Sauna Field Measurement Form (PDF) to measure your new sauna room. Keep in mind saunas do NOT need a high ceiling. In fact, a lower ceiling keeps your heating costs down. A range of about 6'8" to 7'4" is a good ceiling height for an indoor sauna.

Infrared Tent Assembly Photos

WHAT WE LIKE

  • Kit assembly in one hour
  • The sauna tent does not get too hot – only about 130°F
  • The heat from the lights is almost instant (5-10 seconds)
  • Infrared light has many immune boosting and health benefits
  • Light plugs into any grounded 110v electrical outlet

NOTEWORTHY

  • My cats love the infrared light

Infrared sauna tent is the simplest sauna kit available and is designed for one person. It's a wooden frame you assemble and wrap with precut canvas to contain the light and heat emitted from the infrared lights.

SITUATION: You prefer the penetrating heat and immune-boosting effects of infrared lights in your sauna. You live in a condo and want to conserve space. You don't like your saunas too hot (< 130°F). DIY assembly time: 1 hour.

  1. Prep work: None other than a clear place to assemble
  2. Constructing the precut wooden frame only requires a drill with a screw bit.
  3. Screw the light to the frame.
  4. Wrap precut canvas around the frame and secure with the Velcro straps.
  5. Lay down the flooring and set the stool. View step-by-step Sauna Tent Assembly

Infrared cabinets

 

WHAT WE LIKE

  • No construction on the property
  • Minimal effort necessary to assemble and begin using (2-4 hrs)
  • Very portable, although heavy

NOTEWORTHY

  • Many sauna cabinets may come with infrared lights or emitters
  • These are small units and usually only accommodate 2 sauna bathers; 4 in a seated position
  • Need to plug into a standard 110v outlet
  • Do NOT get very hot ~125ºF.

Sauna cabinets are designed to plug-in and enjoy quickly, with minimal owner effort  to assemble and begin using them.

SITUATION: You are entertaining 2 to 3 sauna bathers. You'd rather not endure any construction in your home. You really prefer the heat and immune-boosting effects of infrared lights in your sauna. You don't have much space for a sauna. DIY assembly time: Varies, but about 2-4 hrs for most.

  1. Prep work: None other than a clear place to assemble
  2. These saunas come with the manufacturer's instructions and assemble indoors.
  3. Typically, the sauna cabinet is designed in 2-4 main parts making assembly fairly easily

Since these saunas are designed to plug into a normal 110v outlet, they can take longer to warm up. They are usually designed to accommodate two sauna bathers, and as many as four, when everyone is seated.
