Cedar Sauna Kits for the Do-It-Yourselfer

Countless Ways to Customize and Design Your Home Sauna Kit

A DIY sauna kit is a package containing all the materials to build the inside of a sauna. At Saunafin, we describe the Sauna Material Liner Kit as the "inside skin" of the sauna. You can install a sauna anywhere in your home; (i.e. basement or master bathroom). Sauna kits can also be installed outdoor in a cabana or shed. Our sauna material kits are made of Clear, Canadian Western Red cedar and we can design and customize any shape and size to meet your needs. Sauna kits are the most affordable and effective option when building a sauna, and Saunafin offers the lowest factory direct prices. With over 50 years of experience in the sauna industry, you can trust Saunafin to provide design and installation expertise, excellent customer service, and high quality clear cedar saunas.

ADVANTAGES TO A SAUNA MATERIAL KITThe Sauna Material Kit provides all the special components necessary to properly and easily build your sauna. The sauna kit provides specific cedar lengths. Builder supply warehouses and lumber yards generally carry only 8' or random lengths which creates a lot of waste. The sauna kit also includes such items as cedar molding and door casing which are not readily available.
At Saunafin, our sauna kits have no seams.  We provide only full-length boards (up to 8')  

COSTWhen using Clear Cedar for your sauna, there is no better value than one of our home sauna kits.  Lumber supply and Big Box Building warehouses, carry either premium priced 8' or random length (6'-20') (if they carry clear cedar at all).  Saunas are generally small rooms.  Most use 4',5',6' and 7'. Major mills set aside these high quality "shorts" as less valuable. Well, not for saunas.  Saunafin orders truckloads of shorts at preferential prices and we pass those savings on to our customers.
When purchasing a Saunafin material kit, the heater and door are included at wholesale price levels, making the kit that much more valuable.
Purchasing a kit vs. buying your sauna "a la carte" will generally save you $400-$800.

SAUNA KIT VERSATILITYSauna kitIt is easy to customize a sauna material kit. If the sauna is part of a larger renovation; such as a finished basement, or addition, it is easy to incorporate the sauna kit into whatever space is available. The sauna can be installed to suit particular settings; for example, the exterior can be drywall and painted to match the outside decor of a bathroom.

NOTHING COULD BE EASIERWith the Saunafin Material Kit, building a sauna is one of the simpler do-it-yourself projects. Our rule of thumb is: If you can erect the stud framing, you will have no problem installing the sauna kit. It is designed specifically for the do-it-yourselfer and renovator. The bench framing, heater guard, and moldings are pre-cut. We even include the galvanized nails. If you have not built a sauna before, you will find the instruction booklet and drawings easy to follow.

DO I HAVE TO USE WESTERN RED CEDAR FOR MY SAUNA?While other materials are occasionally used, Western Red cedar is by far the most popular, most attractive and most durable. Cedar has a mild, pleasant fragrance that many people associate with saunas. Western Red cedar's particular properties allow it to expand and contract. This is important in a sauna where the wood is exposed to extremely high, dry temperatures, interspersed with blasts of humidity when water is splashed on the heater or the walls.

QUALITYOur Clear cedar material kits use only kiln-dried, clear, grade 'A' and better, tongue & groove Western Red cedar. The cedar is thick enough to ensure maximum strength & durability and finished on two sides to provide for the best overall finish. Our most popular material kits use 2 x 4 Clear cedar for benches and bench framing (unlike most others who use 1 x 4).

HOW LONG WILL IT TAKE TO BUILD THE SAUNA?The installation time will vary somewhat with the size of the sauna. On average, the sauna kits are installed in 14 - 20 hours. With the specified lengths, pre-cut moldings and pre-hung door, you will save at least 4 - 8 hours on your installation time.Which SaunaFin Sauna Material Kit is Best for You

Comparing All Three Sauna Material Kits

Which is Best for You?

LK Prime:                          
The most economical because of the thinner bench material. Ideal for the price conscious do-it-yourselfer.
Not recommended for building contractor or homeowner buying kit for their builder. Benches take longer to build, so the savings in material is offset by increased labor costs.  
LK Plus:                           
This is the most popular package. Strong, sturdy 2x4 bench tops and supports that are quicker to assemble and have a very substantial look and feel.
The LK Plus starts you off with a first-rate, high quality sauna and lets you pick and choose the options and extras that appeal to you. The 9/16 cedar is as thick or thicker that most sauna manufacturers offer.  You can utilize it with complete confidence.

LK Premium:                     
Starts as an LK Plus, but adds a lot of designer features, popular heater upgrades and accessories. What distinguishes the LK Premium is the thicker 11/16" wall/ceiling lining.
If the thicker wall lining is an important consideration for you, the LK Premium is a great deal. It is also popular with customers who like all the included upgrades.  The thicker cedar is just a bonus.
On the other hand, it you like some of the other features, but the 11/16" cedar is not that important, then you are usually better off selecting an LK Plus and adding the upgrades you like.
(Alert: Some pass off 5/8 cedar as 11/16. Ours is a true 11/16".)

Door Detail

All doors pre-hung (to ease installation)
Doors are 6'-2" tall (R/O=76")

Some are providing 72" to save money and then charging you for 74" door. 
While it may not appear that those 2" mean much. It does to the many people who are 5'11", 6' or 6'1" tall. 
The cedar endcaps on our doors add to the height, make the door stronger (& add to the fabrication cost).
But, it is a better built door, more practical and  suitable for the application.

Construction Details

Click to view installation manual for your selected sauna kit:

Note: Below are merely short form instructions for your consideration. The material kit will come with a full manual including detailed drawings.


Use 2 x 4 construction grade spruce studs to frame the walls and ceiling. If the ceiling span is over 10', use 2 x 6 studs. Unless otherwise specified, for saunas up to 8' x 8', the walls are LINED HORIZONTALLY and FRAMED VERTICALLY. Frame the walls at 16" on center. Frame or strap the ceiling to an inside height of 83-1/2". Frame the ceiling so that the cedar will run the shortest direction. Provide extra blocking for bench supports and heater.

Standard kit height 831/2".  Most  Saunas are 7' height or lower. Minimum height is generally 75" to 78" depending on heater model.
Maximum sauna height should never be higher than 8'.  If you really want higher, we strongly urge being as close to 7' as you are willing to go; i.e. 7'-4" or 7'-6". 

For standard horizontal lining, strapping is not required.
If lining vertically, strap (1 x 2 spf) over the foil to change direction. Can be used to create air space, but it is not necessary.

Electrical rough-in of heater, control and light should be done at this time. If using an outside control, the thermostat should be installed at this stage. (See heater specifications and control wiring diagrams for wire and breaker sizes.) Hook-up of the heater and light can be done after the sauna is completed.

The space between the studs in the walls and ceiling is filled with 3-1/2", R-12 fiberglass insulation.


Vapour Barrier

Foil vapour barrier over the inside edge face of studs over the insulation.

Use the specified lengths of tongue and groove cedar (see "Material Packing List"). Depending on the actual inside finished size of your sauna, it may be necessary to trim these boards. Nail through the tongue only in order to conceal all nail heads (Blind nailing). Use the 11/2" nails supplied. Install the tongue and groove cedar to the ceiling first. Start lining the walls at the floor and work your way up. The first cedar board should be left about 1/2" off the floor. Cut the last board to fit.

Fasteners supplied are galvanized nails and treated deck screws. All fastening is to be blind nailed.

Depending on kit selected, there are clear cedar 1 x 4 or 2 x 4 boards for bench top construction. Depending on the actual inside finished size of your sauna, it may be necessary to trim these boards. Before doing any fastening, select the boards to make sure the better face of the board comes out on the sitting surface. When building the benches, the better side will be face down as you are fastening from the bottom. This is so there are no nails or screws on the finished surface. Use the treated nails and screws supplied. If the sauna is 5' or more deep, the top bench is 20" deep and the bottom bench is 16" deep. If the sauna is 4' deep, the benches will be 20" & 8". Spacing between the bench boards should be about 9/16". (You can make gap smaller, but it will affect overall bench depth. You will have to adjust framing accordingly).
It is important to have two tier benches. the warmest air is closer ot ceiling. Sitting at a lower level, you will not feel the heat.

Door (door picture gallery)
Cedar framed door with 16" x 64" glass or Solid cedar door with smaller 12"x24" window.
All doors are Pre-hung on 9/16" x 4-9/16" jamb.
Standard Door size = 24" x 74". Standard  Rough opening=26" x 761/2". 
(Except Frameless Glass Door = 24" x 72". Rough Opening=271/2 x 75".)
Larger and custom doors available (i.e Tall Door=24"x78", Commercial Door=28"x78", Handicap=36"x80"

Sauna Craft CW- model heaters can be mounted in the corner or on a straight wall.
Tylo Sauna Heaters are designed to mount on the straight wall.

Heater Guard
Use the 2 x 2 for the vertical posts and the 1 x 3 for the horizontal rails. Due to their "cool-touch" shells, Tylo heaters may not require a guard.

Cedar Floor (optional)
Use 1 x 4 cedar, square edge laid over cedar sleepers. Build as with benches with good face on walking surface. Top boards should be spaced approx. 5/8" apart. The sleepers should be placed at 1'-0" on center.

Other Considerations
Commercial saunas should have a drain in the center of the floor (sloped to the drain) to facilitate cleaning.
Most residential saunas have drains, but it is not essential. Water should only be used in moderation. 

For residential, tile is attractive and functional; however it is also acceptable to leave concrete. If floor is sloped, mosaic tiles are best. 
You may add a tile baseboard up the wall 2-3".

About Us

Saunafin is a second-generation family run business that has been manufacturing saunas since 1962. At Saunafin, we continue to pride ourselves on the quality of our materials, our commitment to customer service and our ability to provide both at competitive prices.

What sets Saunafin apart from other online sauna stores?
Two Things: Installations and Walk-In Traffic.  We install about seventy-five saunas a year locally. We have first hand experience with all the minute details and we understand the thought process that goes into planning how the sauna fits in to new construction or renovation plans.

We also have a very busy retail showroom dedicated strictly to saunas and steambaths. We meet daily with homeowners, renovators and custom home builders. We have seven saunas and a steamshower on display. We are the largest retailer of saunas in Canada, and one of the largest in North America. We have continuous hands-on interaction with our customers and we discuss in detail the various items and options we offer. Saunafin has a factory and retail showroom outside Toronto.

Along with our thousands of residential saunas, Saunafin has supplied saunas and steambaths in the Palazzo Hotel Casino and M Resort Casino (Las Vegas), Rogers Centre (formally Skydome), Casino Windsor, Casino Rama, Toronto Blue Jays and the Ottawa Senators. We are a specified contractor for the YMCA, LA Fitness and Movati Fitness. Our years of installing saunas have provided us with a wealth of practical experience. We use this experience to help you plan your sauna and provide a comprehensive and easy to install sauna kit.

We manufacture our own line of sauna heaters, which are sold under the Sauna Craft brand name. We are also the Canadian distributor and the largest North American provider for the highly regarded TYLO sauna heaters manufactured in Sweden. In 2017, Saunafin's owner Mike Wynn was named Chairman of CSA (Canadian Standards Association) sub-committee for sauna heaters. Relying on his 30 years experience in the sauna business, he has been actively involved with CSA in updating heater standards as regulatory bodies try to consolidate standards across North America and Europe.

Saunafin staff,

I purchased the 5x7 LK N Plus package for my personal use. Saunafin met or exceeded all my expectations in pricing, quality and schedule. Their website was straight forward and accurate. The delivery schedule was as promised, with all the material packaged properly for protection. The cedar is beautiful, and the material estimate was precise.

I rarely take the time to write appreciation letters, but this experience was A++. Everyone involved is to be commended. I highly recommend Saunafin to anyone seeking a sauna. All the Best,

William Evans
