1. Indoor Sauna Plans...

Building an indoor sauna will let you use the sauna 12 months of the year. Ideally, your sauna design should allow for a cooling down or rest area, a shower beside the stove room and a dressing room to hang up your clothes or house coat. A home sauna is often built into the basement, a cold fruit cellar, a converted car garage, a spare room or as part of a bathroom. The sauna heater and the controls will need a new 240 volt circuit hard wired from the electric service panel.

2. Indoor Sauna Design & Sauna Size...

Sauna sizes vary from a small one person sauna room that could fit into tight areas, to larger sauna room sizes for home, family or residential sauna use where many people gather together to enjoy the sauna health benfits. A commercial sauna room can range from a 6'x6' size to one as large as a 10'x14' size.

Great Saunas top selling sauna layouts for home or residential sauna sizes are the 5'x7' and 6'x7'. The 4 person top bench is 7' long and easily seats four persons and is long enough for 1 person to lay down. The sauna sizes of 5 x 6, 5 x 8, and 6 x 8 are also popular for home saunas and often have a third bench in an L-bench design.

Great Saunas recommends the saun height inside the saunas to be 7'. The 7' sauna ceiling height reduces the heater warm-up time to a minimum and prevents heat from rising into the unused space above the sauna room. If the sauna height is less than 80", lower the entire sauna bench set a few inches to compensate.

Typical Building Plan
for a Family Sauna

For commercial saunas, the sauna room sizes of 6 x 8, 6 x 10, 8 x 8 and 8 x 10 are very popular as they can seat as many as seven to ten persons at a time. Commercial sauna rooms with an 8' ceiling height sometimes use a 3-level bench layout in order to gain the maximum seating possible. A 2-level set of benches with a sauna height of 96" is simply poor planning and will be expensive to heat.

The majority of saunas that we have shipped across North America are a standard rectangle shape. Choosing an irregular shaped sauna can increase the costs of your sauna.


To maximize the use of your T&G and bench material, designing a layout where inside measurements are by the foot should be your target. This will allow you to use the full length of the T&G cedar boards that should be installed horizontally to make the sauna room look and feel bigger. If you plan to lay down on the top bench, the bench length should be a minimum of 6' with a 20" width. Sauna sizes like the 4'x6' and 4'x7' usually have benches that, at 16" wide, are too narrow to lay down comfortably. Conclusion: a sauna room, like the 5'x7', is ideal and should be framed to create a 60"x84" space between the wall studs.

An entirely new section on outdoor sauna plans and design is coming soon. Information on outdoor plans, designs and sizes is currently available on a case-by-case basis. Just email us your sauna ideas and we'll work with you to create a great plan.


3. Sauna Specifications...

Your sauna ideas, sauna drawing or sauna blue print will be used to create a full set of sauna specifications for you. Many of our customers fax their sauna drawings to us so we can get started on your sauna. A sauna material list will then be included with the sauna blueprint for a complete sauna room design from Great Saunas.

Sauna Design for a 1 person 3x5 Layout

3x5 Sauna Layout
The design and size of the sauna room will depend on:
1. the number of persons using it at one time
2. bench layout, 2 benches, 3 benches or 4?
3. benches to be regular 2-tier or L-shape?
4. sauna door location
5. the heater or stove location, its size and specifications

4. Sauna Door Location...

During your design process be sure to account for the sauna door location.  If the door is on the longest wal l(which is our standard), door placement should allow enough space for the heater, guard and door casing.

A home or house sauna can be put into any space inside or outside of your home.  Traditionally your sauna can fit inot any space like a basement, bathroom, outdoor shed or even a garage.

5. Sauna Heater Location & Specs...

The sauna heater is usually installed in a corner of the sauna room so it uses only a small area of the corner. If the heater is mounted across the corner, the construction of the heater guard becomes complicated as the heater guard will need to be built 3-sided to match the perimeter and outside shape of the heater. The easiest way to install the heater and the heater guard is to mount the heater on only one of the sauna walls so the heater guard can be a simple 2-sided rectangular design.

6. Sauna Bench Specifications...

Sauna bench specs will be added to this section shortly. In the meantime, the section on "How to Build a Sauna" provides excellent detail on bench planning and building. CLICK for sauna bench specs.

7. Frequency of Sauna Use...

A residential or home made sauna is generally used a few times a week by the whole family or individuals as required. With a typical warmup time of 20 to 30 minutes, the family sauna is ready quickly. If time is available to use it every day, feel free to do so. Many sauna enthusiasts average 5 saunas per week. It is up to each individual whether you prefer to start the day with a cleansing sauna or use the family sauna in the evening to relax and clean up after the day is done.

A commercial sauna often found in fitness clubs may be switched on in the morning and off again at night, usually by an automatic sauna timer.

8. Use of Water...

With today's trend toward the Finnish type of high heat dry sauna, plumbing for water inside the sauna is not needed.  Furthermore, the electrical code now prohibits a water tap directly above the heater. When you go into your sauna, bring in your bucket and ladle and pour a ladle full of water on to the hot rocks to obtain your desired humidity level.

The traditional sauna can be used as a completely dry sauna, or add some water to hot rocks to get moisture in the air.


These sauna plans and layouts can also be used as "banya plans" to build a Russian sauna or Russian banya. The "banya" or "bania" is normally used at a very high temperature with high humidity. The Russian banya design and construction is quite similar to the Finnish sauna.

Planning Ideas for Unique Situations...

Lack the room for a sauna shower? One idea that works fine is to locate the sauna shower inside the 6'x7' or 6'x8' sauna room. Use the shower after the sauna is finished. You will also need to apply a coat of our famed anti-stain preserver to your wood parts in order to protect the wood from water marks.
