So, if you're ready to invest in a sauna and start reaping the benefits of regular sauna use, keep reading to learn everything you need to know before making your purchase.

Size and Capacity

When it comes to buying a sauna, size and capacity are important factors to consider. Here are some sub-sections to help you make the right decision:

Indoor or Outdoor

Before you choose the size of your sauna, you need to decide if you want to install it indoors or outdoors. Outdoor saunas can be larger than indoor ones because they don't have to fit within the confines of a room. However, indoor saunas are more convenient and can be used year-round.

Number of Users

Another important factor to consider is the number of people who will be using the sauna at the same time. If you plan to use the sauna alone or with one other person, a smaller size may be sufficient. However, if you plan to have multiple people using the sauna at the same time, you'll need a larger size to accommodate everyone comfortably.

Here is a table to help you determine the right size sauna for your needs:

Number of Users Sauna Size
1-2 4'x6'
3-4 5'x7'
5-6 6'x8'
7-8 7'x8'

Available Space

The amount of space you have available will also play a role in determining the size of your sauna. If you have limited space, you may need to choose a smaller sauna. However, if space is not an issue, you can opt for a larger size.

Keep in mind that the size of your sauna will also affect the cost. Larger saunas will generally be more expensive than smaller ones. However, it's important to choose a size that fits your needs so that you can fully enjoy the benefits of your sauna.

Heating System

When buying a sauna, one of the most important factors to consider is the heating system. The heating system is responsible for creating the heat inside the sauna, so it is important to choose a system that is reliable, efficient, and safe. Here are some factors to consider when choosing a heating system:

Type of Heater

There are two main types of heaters for saunas: traditional and infrared. Traditional heaters use rocks or other materials to create heat, while infrared heaters use light to create heat. Traditional heaters are known for their ability to create a soft, moist heat, while infrared heaters provide a dry heat that is said to be more therapeutic. When choosing a heater type, consider your personal preferences and the intended use of the sauna.

Power Source

Another important factor to consider when choosing a sauna heater is the power source. Sauna heaters can be powered by electricity, gas, or wood. Electric heaters are the most common and convenient, as they can be easily plugged into a standard outlet. Gas heaters are more expensive to install, but can be more cost-effective in the long run. Wood heaters are the most traditional option, but require more maintenance and are less convenient to use.

Heating Capacity

The heating capacity of a sauna heater is another important factor to consider. The heating capacity refers to the amount of heat that the heater can produce, and is measured in watts or BTUs. The size of your sauna will determine the heating capacity that you need. As a general rule, you will need about 1 kW of heating capacity for every 50 cubic feet of sauna space. Make sure to choose a heater with sufficient heating capacity to ensure that your sauna reaches the desired temperature quickly and efficiently.

Material Quality

When considering the purchase of a sauna, material quality is an important factor to consider. The quality of the materials used in the construction of a sauna can affect its durability, safety, and overall performance. In this section, we will discuss two key sub-sections to consider when evaluating material quality: Wood Type and Quality of Construction.

Wood Type

The type of wood used in the construction of a sauna can affect its performance and longevity. Here are some of the most common types of wood used in saunas:

Wood Type Advantages Disadvantages
Hemlock Resistant to warping and cracking, affordable May require more maintenance, not as visually appealing as other woods
Spruce Lightweight, affordable May not be as durable as other woods, may require more maintenance
Cedar Naturally resistant to decay and insects, visually appealing Expensive, may have a strong aroma, may require more maintenance
Pine Lightweight, affordable May not be as durable as other woods, may require more maintenance

Quality of Construction

The quality of construction is another important factor to consider when evaluating material quality. Here are some things to look for:

  • Make sure the wood is solid and not made from plywood or other composite materials.
  • Check for gaps or cracks in the wood that could let heat escape.
  • Inspect the seams and joints to ensure they are tight and secure.
  • Check the door to make sure it fits snugly and has a good seal.
  • Look for any signs of poor workmanship, such as uneven surfaces or rough edges.

By considering both wood type and quality of construction, you can ensure that you are purchasing a sauna that is built to last and will provide you with years of enjoyment.

Additional Features


Lighting is an important aspect to consider when purchasing a sauna. The right lighting can create a relaxing atmosphere, while also providing enough light to see clearly. LED lights are a popular choice for saunas, as they are energy-efficient and can be set to different colors to create a calming ambiance. Some saunas also come with fiber optic lighting, which can create a starry night effect on the ceiling.

Sound System

A sound system can enhance your sauna experience by providing relaxing music or nature sounds. Look for a sauna with a built-in sound system or one that is compatible with Bluetooth speakers. Make sure the speakers are moisture-resistant and can withstand the heat of the sauna.


Aromatherapy can help create a more relaxing sauna experience. Some saunas come with built-in aromatherapy dispensers, while others may require you to add essential oils manually. Consider what scents you prefer and make sure the sauna you choose is compatible with your preferred method of aromatherapy.

Ease of Use

Make sure the sauna you choose is easy to use. Look for saunas with intuitive controls and easy-to-read displays. Some saunas come with remote controls, which can be convenient for adjusting settings while inside the sauna. Also, consider the ease of maintenance, such as how easy it is to clean and replace parts.

Overall, these additional features can enhance your sauna experience and make it more enjoyable. Consider which features are most important to you and choose a sauna that meets your needs.

Maintenance and Upkeep

Proper maintenance and upkeep are essential for ensuring the longevity and optimal performance of your sauna. Here are some key factors to consider:

Cleaning Requirements

Regular cleaning is necessary to keep your sauna hygienic and free of bacteria. The cleaning process will depend on the type of sauna you have, so be sure to consult the manufacturer's instructions. Here are some general tips:

  • Wipe down the benches, walls, and floor with a damp cloth after each use to remove sweat and dirt.
  • Use a mild detergent or sauna cleaner to clean the wood surfaces periodically.
  • Allow the sauna to fully dry before using it again.


When purchasing a sauna, consider the durability of the materials used. A high-quality sauna should last for many years with proper maintenance. Look for saunas made from high-grade wood, such as cedar or hemlock, which are resistant to warping and cracking. Avoid saunas made from low-quality materials, such as particleboard or MDF, as they are prone to damage and deterioration.


Make sure to check the warranty offered by the manufacturer before purchasing a sauna. A good warranty will cover any defects or malfunctions that may occur within a certain period of time. Look for a warranty that covers both the sauna and the heater. Be sure to read the terms and conditions carefully to understand what is covered and what is not.

Wrap Up

Buying a sauna is a big investment that requires careful consideration. Before making a purchase, be sure to evaluate your needs, preferences, and budget to determine the best type of sauna for you. Here are some key takeaways to keep in mind:

  • Decide on the type of sauna that best suits your needs, whether it's a traditional, infrared, or steam sauna.
  • Consider the size of the sauna and the space where it will be installed.
  • Think about the materials used to construct the sauna, such as wood type and quality.
  • Evaluate the heating system and controls to ensure they meet your preferences and needs.
  • Factor in additional features and accessories, such as lighting, sound systems, and seating options.
  • Research different brands and manufacturers to find a reputable and reliable seller.
  • Set a budget and stick to it, keeping in mind that a higher price doesn't always equate to a better product.

By taking the time to thoroughly research and evaluate your options, you can feel confident in your decision to purchase a sauna. Whether you're looking to improve your health and wellness or simply enjoy a relaxing sauna experience, a sauna can provide a range of benefits for years to come.
