What is the difference between a Modular Sauna and an Interior Pre-Cut Sauna?

A Modular Sauna is a panelized sauna that comes as prebuilt, modular panels that interlock into a  freestanding sturdy sauna room. The ceiling panels are secured atop to enclose the room. The modular sauna option gives you the freedom to relocate at any time! Modular saunas can be installed inside or outside (with the addition of a roof kit option)

An Interior Pre-Cut Sauna is specifically designed for new construction or situations where you have a spare room that's already framed in and insulated. Your walls and ceiling will then need to covered in plywood. A Pre-Cut Kit will include vapor barrier, T&G (Tongue and Groove) panels, sauna benches, a sauna heater, door, and all necessary trim pieces. Interior Pre-Cut saunas are permanent and cannot be relocated.

How hot do saunas get?

180-194 Degrees F. All of our Electric Sauna Heaters carry either a UL or ETL listing which mandates that the high limit for electric sauna heaters in a 7' high room be 194F at the ceiling level. We also carry gas sauna heaters and wood burning sauna heaters. To ensure that a sauna room can get hot it is important to make sure it is sealed and vented properly so the heater can do its job efficiently. A good sauna heater will again heat a room to 180-194 degrees. 

What are the benefits of Himalayan Salt?

The Benefits: Himalayan salt contains trace minerals like potassium, magnesium, and calcium, which can help maintain electrolyte balance in the body. It may aid in regulating hydration levels and promoting proper fluid balance due to its mineral content. Some people believe that using Himalayan salt in place of regular table salt can contribute to improved respiratory health and better sleep quality.

How does it work? By gently heating the Himalayan crystal salt, the hygroscopic (moisture attracting) properties of the salt are activated, allowing the natural humidity in the air to condense on the surface of the salt blocks, triggering the natural ionization process. During this process, the salt releases negative ions that in turn attach themselves to dust, bacteria, and other pollutants, effectively purifying the circulating air. This release of negative ions also interacts with the body on a biochemical level, aiding in the increased release of the body’s natural mood balancing chemical serotonin. Increased levels of serotonin are widely thought to positively impact digestion, memory, sleep, appetite, and mood.  

Why Himalayan SaltWhen heated, Himalayan salt releases negatively charged ions which serve to purify the circulating air as well as allow our bodies to reap health benefits including stress reduction, energy increases, and mood boosts at a biochemical level. The vast wellness benefits of traditional dry saunas are well-known and when the effect of pure Himalayan salt is added, the result is a truly unbeatable sauna experience.

How many people can sit in a sauna?

Our Sauna Kits are available in 1-3, 4-8, and 8+ person capacities. If a sauna is listed as a 1-3 person sauna then 1-3 average sized people would sit side by side comfortably. (depending on model) When choosing your sauna kit make sure the space you have available and the idea you may have can accommodate the amount of people you want to fit. If you need assistance reach out to so that can assist you further. The average home sauna will accommodate 4 people.  

Why is ceiling height so important in a traditional sauna?

Because heat rises. To keep the temperature optimal in your room the ceiling height in your room should not exceed 84". If the ceiling height is to high the heat well not reach you as intensely. Keep comfort in mind, especially if you are taller, you may want to have the ceiling height to compliment your height. The standard height is 72" and 84".

Do I need a structural permit for my sauna?

Outdoor saunas and structures that are 120 sq ft or less, do not require permits (in the U.S.). Some counties allow larger structures of up to 200 sq. ft. without permits. You may run into some problems if you put your sauna right on the property line you share with a neighbor, a parking strip or an access easement.While adding a residential circuit is fairly straight-forward for any electrician, it may not be a bad idea to get an electrical permit for your indoor sauna. You can call your county permitting department to easily check. Most sauna installations require 220/240v power with a hard wire connection to a separate 30 or 40 amp breaker in your electrical panel. In some instances, a small traditional style sauna can be wired to 110/120v circuit, if the circuit to the panel with a #12 gauge wire.You will definitely want an electrical permit for your commercial sauna.

Do I need an electrical permit for my sauna?

Most Electric Sauna Heater installations will require a dedicated 240 volt 40 amp GFCI protected circuit. If you are adding your sauna to a spa, gym or any other commercial setting, you would definitely want an electrical permit for your sauna. Commercial saunas often have (2) 240v 40amp circuits. If you are remodeling the construction on your home it's typically a good idea to pay for an electrical permit. Then, when you sell your home you've covered your bases. Of course, many home owners simply declare on their Form 17 any work that was done without permits. Additionally, home saunas generally do NOT require a structural permit.

Is venting a sauna necessary?

Yes, It is important to to have fresh air moving through the sauna for proper heater function. The best vent locations are near heater just off the floor & on a opposing wall or a gap under the sauna door. If a sauna is not vented correctly or at all issues can occur with the heater and the air inside. Always make sure to follow any installation guides so that you do not have to worry about replacing and components of your sauna in the future. VENTING IS IMPORTANT!

Do saunas require a floor drain?

saunas do not necessarily require a floor drain. While some saunas may have floor drains for convenience and easy cleanup, they are not essential components. Many saunas utilize other methods for managing moisture, such as sloped floors, absorbent materials, or ventilation systems, to maintain a dry and comfortable environment without the need for a drain. However, the presence of a floor drain can be beneficial in certain situations, especially in commercial or high-traffic saunas, where it may help manage excess water and prevent slipping hazards. Ultimately, the necessity of a floor drain depends on the specific design and requirements of the sauna.

Is a sauna expensive to operate?

A sauna heats up fairly quickly and is only ON when in use. The average home sauna costs around $3-5 per month to operate, when used for one hour- 3 days a week. The operation costs may also vary depending on the type of heater or other sauna accessories you add. Gas heaters ran off of propane or a gas line from your home may be cheaper. There are also wood burning heaters that may require more work. 

How does a traditional sauna differ from an infrared sauna?

A sauna is a room where the environment is very hot and dry. Water is ladled onto the sauna rocks to generate steam, so by definition, the infrared experience is not a sauna at all. Infrared penetrates the body with infrared rays and does not warm the actual room itself. Infrared panels achieve this at a low temperature and are helpful in relieving sore joints and muscles. The wet/dry effect from a traditional sauna is a total body experience, which ultimately provides joint and muscle relief, and a long list of other health benefits.

What are the Pros & Cons of the different heater types?

Gas Heaters: 

Pros - The Gas Heaters will provide a higher quality of heat that cannot be achieved by an electric heater.

Cons - Gas Heaters are more expensive and larger than most other heaters.

Electric Heaters:

Pros - The Electric Heaters are the most common heaters on the market. They offer a simplistic installation and a cheaper breakthrough cost.

Cons - Electric Heaters will add to your monthly electrical bill, depending on usage.

Wood Burning Heaters:

Pros - Wood Burning Heaters are the oldest types of sauna heaters which will provide you with the most authentic sauna experience.

Cons - Maintaining a certain temperature is much more difficult with a Wood Burning Heater.

How do I know what power heater to purchase?

A common practice is to use your sauna's cubic foot measurement. 99.9% of heaters will be based off of cubic foot measurements. 

There are 2 main ways to go about determining the heater you need.

First, take take your Length x Width x Height (in ft.), then divide that number by 50.

i.e. A 5' x 7' x 7" sauna is 245 cubic feet / 50 = 4.9. Then round that number up to the next best heater. So the minimum is 4.9 kW to heat this sauna. 

Another way is to take your Length x Width x Height (in ft.), and match that number to any of the heaters we have on the website. Their specifications for cubic feet maximums will be listed in the descriptions.

How do I install my sauna heater?

All heaters should ultimately be installed by a licensed electrician or HVAC professional. Your sauna heater should include an installation guide. Each heater will have specifics on how far the unit should be mounted off the floor as well as other pertinent information. If you have any questions, please contact the manufacturer.

What is a contactor box?

Contactor Boxes are responsible for protecting the timers/controllers from any electrical surges. They prevent the units from receiving too much power. IF you do not have a contactor box there are a lot of things that can go wrong. If you need help make sure you reach out to an expert. 

Where can I find heater manuals?

We offer Product Manuals for the heaters that are available on All the manuals are in PDF format and available for download. You may also receive heater manuals with your heater when it arrives. It is convenient to have both available.

Do the Electric Sauna Heaters plug into an outlet?

No they do not. It is recommended that a licensed electrician hook up an electric sauna heater because it is hard wired. The Electric Sauna Heaters do not plug into standard outlets. 

How do I reset my sauna heaters high limit switch?

All UL or ETL Listed sauna heaters have reset buttons in case the heater exceeds the allowed high limit (approximately 194F at ceiling level). This high limit switch is built into heaters for safety purposes. It is not uncommon for this switch to have to be reset similar to a tripped breaker on a circuit breaker panel of a home. You should consult your owner’s manual for specifics.

Most high limit reset buttons are located underneath the sauna heater for wall mounted units and in the back if it is a floor standing sauna heater. If you feel and/or hear a click when depressing the button, your sauna heater is reset. A springy button (no click) means that the high limit was not the issue and other troubleshooting may need to be done if the heater is not working.

Is it possible to achieve a dry sauna with some steam?

Yes! The Scandia units will provide the highest level of humidity in the room while still giving you that dry sauna heat. You can do this by pouring water over the sauna rocks to increase the humidity levels. If your heaters does not have a solid rock try like the ones from Scandia, than be cautious as long-term use of dumping water can lead to parts needing to be replaced and potentially a whole new sauna heater. 

How long does it take for a sauna to fully heat up?

A traditional sauna generally takes between 30 and 45 minutes to fully heat up. While the sauna itself is heating up, the sauna rocks will be heating up as well! You want to make sure the heater you choose for your sauna is the right size and not to big or too small. We do have sizing guides and expert help at your disposal so we can help you out a long the way!

If the pilot goes out (or get blown out), on the Scandia Gas Sauna Heater does it turn off the flow of gas? 

Yes, if for any reason the pilot lite goes out, it will automatically turn off the gas at the gas valve. This is a standard feature for the Scandia standing pilot version gas heaters. The Scandia Gas Sauna Heater, piezo-controlled, light the pilot electronically on-demand, which makes them impervious to wind conditions.

Can excessive wind affect the standing pilot on the Scandia Gas Sauna Heater?

Yes, in rare occasions strong wind can blow out the pilot light, on the Scandia Gas Sauna Heater. This condition can be resolved easily by placing a small piece of screen on the inside of the intake cover. This screen will break the excessive wind but will not negatively affect the airflow of the heater.

What is required to build an Interior Pre-Cut Sauna in my home?

A spare framed room with vertical studs and insulated walls & a non-permeable floor.

Most electrical sauna heaters work best on their own circuit. Most sauna rooms will use a 240 volt powered heater, which will heat your sauna much faster. It is recommended to have a licensed electrician install the sauna heater.

You also need insulation in the walls and a way to vent the sauna, generally back into the house. Venting directly outside may cause airflow problems for your heater. You do not want cold air blowing into your sauna from above, only below near your heater. 

Noteworthy: The Interior Pre-Cut Saunas finish the interior of the room. Pre-Cut saunas are permanent and cannot be relocated. If you are interested in a sauna that you can relocate at some point, check out our Modular Indoor and Modular Outdoor sauna kits!

Yes, the Modular Sauna Kits can be assembled and re-assembled somewhere else. That is the beauty of these saunas. You can also place them outdoors if you cover them with a roof they are a very pretty outdoor or indoor sauna solution. 

What is the purpose of the backrests along the upper bench wall found in the sauna kits?

The backrests keep your back off of the sauna wall boards to prevent sweat and oils to be absorbed into the wood, helping preserve them for many years. You can also use our scandia sauna wood oil to preserve and increase the life of your sauna. We recommend this with every sauna purchase.

How do I clean my sauna?

We recommend sweeping or vacuuming your sauna for dirt, hair, and dust, in order to keep your sauna in tip-top shape. After you've done that, we recommend treating your sauna with Sauna Wood Oil. WE also recommend a light sanding every 6 months - 1 year. This will help with any cedar wood discoloration and help with long-term preservation of your sauna. Take these maintenance steps seriously as they do play a huge roll in helping your sauna investment.

How do I clean my sauna rocks & sauna heater?

Your sauna rocks can be removed from your heater and soaked in soapy water to remove any debris. (Make sure that the sauna rocks have had plenty of time to cool down before you handle them) After you've let your sauna rocks soak, make sure you let them dry before placing them back into your heater. Cleaning your sauna heater will be a lot easier when the rocks are removed. Most electric sauna heaters will not require much maintenance, but you can wipe them down with a rag. 

What are some of the benefits from Sauna Bathing?

There are numerous benefits from Sauna Bathing:

A saunas' dry heat has profound effects on the body. The pulse rate jumps by 30% or more, allowing the heart to nearly double the amount of blood it pumps each minute. Most of the extra blood flow is directed to the skin; in fact, the circulation actually shunts blood away from the internal organs. Eases pain within the joints and muscles, due to the increased blood flow. Regular sauna use is shown to regulate the appetite, increase metabolism, and improve oxygen utilization, helping to fuel weight loss along with a reduction in body fat. Heat has been proven to positively impact your mitochondria, the ‘batteries’ powering your cells, helping your body naturally produce more energy and stay fit. 

If you sauna for just 10-15 minutes 4-7 times a week at the heat levels of 185-200 degrees, you can experience a decrease in your likelihood of cardiovascular issues. You can also decrease your likelihood of all causations of death when you make using a sauna apart of your daily routine. 

Remember to stay hydrated and consult with a doctor if you have any prior health conditions before you use a sauna more regularly. And if you are interested in adding a home sauna or commercial sauna make sure you reach out to us via email -> or +1-888-503-8157
