Sauna Kits for the Do-It-Yourselfer


Countless Ways to Customize and Design Your Home Sauna Kit

indoor cedar sauna material 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 or Clear Canadian Hemlock. 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 cedar and hemlock saunas.

Clear Cedar

Plus or Premium or Floating

LK Plus

LK Plus (“the original”) was the first style of sauna kit we began with over 50 years ago. Still the big seller, but the increasingly popular Premium and Floating bench kits are catching up.

2x4 cedar for bench tops and bench framing.

Standard heater is the Sauna Craft CWM series with TPT3 mechanical control. Upgraded Sauna Craft and Tylo are available as optional upgrades.

Optional & Upgraded doors, skirting, backrests, floor boards & accessories.

LK Premium As LK Plus with a bunch the most popular upgrades and upgrades included in the package. 2x4 bench tops & framing. Includes upgraded Sauna Craft CW-XR heater & EL-13 electronic control. Built in designer backrest behind top bench. Cedar skirt in top bench riser. Sauna bucket & ladle, thermometer and light shade.

LK Floating bench As LK Plus except for the benches. With the floating bench style, you provide your own bench sub-structure( 2x6 or 2x4 SPF (spruce, pine, fir). We provide 1x4 s4s cedar for bench tops. There are no legs or floor supports. The bottom bench extends fully under top bench. Floating bench is an increasingly popular style with those looking for more modern, open appearance. It is especially popular with those selecting a full frameless glass front wall

  • All tongue & groove (t&g) lining material is 11/16” thickness
  • Full lengths (up to 8’) for t&g cedar for walls & ceiling. (May be limited to one wall of 8’ full length per sauna.)

Knotty Cedar

Knotty Lining with Clear Benches

The Knotty Kit is a cost package using the ever-popular Western Red Cedar.
The cost saving is achieved in a couple of different ways.

One way is the wall/ceiling lining itself.
Knotty cedar has all the great qualities of clear cedar, but is significantly less expensive. Some also prefer the “rustic” look of knotty cedar. It is especially popular for outdoor and cottage saunas.

Another cost savings is the benches. The bench tops are 1x4 s4s cedar (as opposed to the 2x4 used in the LK Plus & Premium packages). To compensate for the thinner bench tops, we provide additional floor supports (legs)-no more than 30” on center.
The 2x4 bench tops are an option for either Econo Kit.

Lastly, the Knotty kit includes the Saaku heater with built in controls. Manufactured for Saunafin by Helo saunas of Finland. It is a quality heater with generous rock capacity. The Saaku is a lower priced heater model.
Sauna Craft & Tylo are both available as optional upgrades


Floating Style or Boxed Benches


Hemlock is a popular alternative to cedar. The color is a uniform light brown.

Hemlock is a “soft” hardwood that holds up well in saunas.

SaunaFin has to style of Hemlock sauna kits. The difference is the bench style.

The “Boxed” benches have full top and bottom skirts, which conceals the substructure.
The “Floating” benches have full depth bottom bench. Open below with no visible legs or bench supports. The Hemlock material provide hides the bench sub-structure.

In both cases, you provide the SPF (spruce pine, fir) to frame the benches. The 1x4 s4s Hemlock seating surface conceals the framing.

Standard heater is the Sauna Craft CWM series with TPT3 mechanical control. Upgraded Sauna Craft and Tylo are available as optional upgrades

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 material 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).
(Our LK Prime Knotty sauna kits use only STK (select tight knot) Westerrn red cedar for lining and clear cedar for the benches)

HOW LONG WILL IT TAKE TO BUILD THE SAUNA?The installation time will vary somewhat with the size of the sauna and the package & options selected. On average, the sauna kits are installed in 14 - 20 hours. With the specified lengths, pre-sorted components and pre-hung door, you will save at least 4 - 8 hours on your installation time.


Construction Details

Click to view installation manual for your selected sauna kit:

         "Econo Cedar Kits"


       "Hemlock Kits"



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 can, i.e. 7'-4" or 7'-6". (Extra cost for additional cedar.)

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 to the ceiling first. Start lining the walls at the floor and work your way up. The first 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 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.

Larger and custom doors available (i.e Tall Door=24"x78", Commercial Door=28"x78", Handicap Access=36"x78")

Sauna Craft CW- model heaters can be mounted in the corner or on a straight wall.
Tylo  (& Saaku) 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. 

Floor (optional)
Use 1 x 4, square edge laid over 1x4 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 (public) 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. (Our rule of thumb: If you are doing complete reno; i.e., breaking floors, new shower & bathroom, etc., we would suggest a sauna drain.  If you are putting sauna in to an already finished area, it is likely not worth the cost to add a drain.

For residential, tile is attractive and functional; however, it is also acceptable to leave cement.  If sauna is on upper level with wood sub-floor, there should be a rubber membrane, cement scratch coat and tile (like shower floor).
If floor is sloped to drain, mosaic tiles are best.
You may add a tile baseboard up the wall 2-3"

The heart of every sauna is the sauna heater.
Tylö sauna heaters are widely renowned and greatly respected for their high quality and distinct features - but not everyone knows all the reasons for this. That's why we'd like to take this opportunity to point out some of the most important benefits of the Tylö design and explain what this means for you. Read on to find out why the hottest range of sauna heaters on the market knocks all the others cold.

Safe to touch.
"Thermosafe" velvety covering ensures a low surface temperature - just 40°C on the front and sides of the heater.

Quickest heat-up time.
Twin side chambers maximize the through-flow of air, minimize heat-up time and economize on running costs.
No other sauna heater uses less energy. 

The lowest energy consumption.
Test after test confirms that Tylö is the most energy-efficient sauna heater.

The most even bathing temperature.tylo sense combi plus sauna heater model
A divided output is the secret behind the constant bathing temperature and lower energy consumption of a Tylö heater. Divided output means the heaters elements cycle in stages. Other heaters go on/off, on/off, etc. causing a temperature swing. Tylo heaters maintain an overall higher and more consistent temperature.

The finest material quality.
Only Tylö has a solid-cast top, inner casing and stainless steel stone compartment.

The best heating elements.
Tylö is the only sauna manufacturer to produce its own heating elements - the very heart of every heater. High quality here is crucial for a long service life, and Tylö elements are widely regarded as unsurpassed.
Tylo sauna heaters infographics

Optimum water sprinkling.
A deep generously proportioned stone compartment, and direct contact between the stones and the heating elements ensure perfect water sprinkling with 100% vaporization. 

The right quantity of stones.
Tylö makes sure that the quantity of stones is perfectly matched to the output. Too many stones prolong heating-up times, leading to higher energy consumption and poorer steam generating performance. Tylö heaters are also the only ones on the market that can be used with or without stones.


Tylo sauna heater

Built-in humidifier.
This unique Tylö feature further enhances your sauna bathing experiences.

Superior performance.
With a Tylö heater, you can enjoy a pleasant sauna, wet or dry, at whatever temperature you choose from 40-90°C (104-194°F).

Best in the test.
Time and time again Tylö has scored top marks in Finnish sauna tests. Tylö was first awarded the coveted 'Best in Test' accolade in competition with seven Finnish heaters in 1982. A test published in a Finnish magazine (Kuluttaja no. 5, 1995) confirmed that Tylö also has the quickest heating-up time and lowest energy consumption. A SEMKO test in April 1999 confirmed this result and also proved that the steam generating performance of Tylö heaters was unrivaled.

Combi (Soft Sauna)

Click for more info:  Tylo Combi Steaming Sauna Heater Brochure


The Tylo Sense Combi is quite simply the most sophisticated sauna heater on the market - the only heater that lets you enjoy traditional or Soft Sauna in one and the same room. The choice is yours. We call it Soft Sauna.

A gentle way to share a pleasurable experience. It is just as much a way of life as it is a technical sensation, and yet it takes up just a few square meters of space in your home. Invite your friends and family, select a therapeutic essential oil, feel the warmth and gentle. Steam engulf you, and enjoy being together. Let Soft Sauna make an impression on your day.


What's Your Temperature?

Soft Sauna picks up where traditional saunas leave off. Some people prefer a hot and quick sauna, others like to linger in mild temperatures, enjoying the gentle steam and aromatic fragrances. Test for yourself which temperatures and options are ideal for you and your relaxing moment.

Imagine having a family home spa with the resources of a professional spa where you can relax together, exquisitely engulfed in steam and aromatic scents – and yet also be able to enjoy the relaxing dry heat of a traditional sauna. Choose the sauna cubicle and heater that suits you and the way you want your moment to be. A moment that stretches on and beyond.

Double Your Enjoyment

The Combi is like having two saunas in one. In dry mode, it operates like a typical sauna - high heat, low humidity. In "soft sauna" or steam-sauna mode, it is an entirely different sensation. When you splash water on the rocks, you to get that blast of heat. Many of those who enjoy saunas love that sensation. Others find it a bit too intense. When you slow boil  the water, you soften the heat. It takes the edge off. The Combi broadens the appeal of saunas. Those who have historically not like saunas really enjoy it. And old fashioned sauna enthusiast love it even more. You can still splash water on the rocks in steam mode to get that wave of extra heat. The Sense Combi is a true hybrid. Two distinct sauna experiences in one and the same room.


Can I Have Steam In a Cedar Room?

The Combi produces steam and the sauna is more humid that a typical sauna, but it does not generate steambath levels of steam. It is not a Turkish bath. You will see steam rising off the heater and you will feel the difference, but the walls do not get wet. And once the Combi has completed its steam cycle, the sauna portion comes on high for 20 minutes to help bake the room dry.

Saunafin staff,

I purchased the 5x7 LK  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
