How the Shape of Your Sauna Can Enhance the Overall Heat Distribution

If you have ever sat in a sauna, you may have noticed that, on occasion, the heat levels feel a bit different depending on where you sit inside it. This is a relatively common phenomenon, and what you may not realize is that the shape of your sauna plays a significant role in how the heat is distributed inside. Barrel sauna kits may offer a vastly different experience when compared to cube saunas, for example. At SaunaFin, we offer a wide variety of sauna shapes that can help enhance your experience.

Learn how the shape of your sauna can enhance heat distribution and how to choose the right design for your needs.

Why Does Heat Distribution Matter?

Heat is the defining characteristic of any sauna, and it is the heat that provides all of the health and wellness benefits that users strive for. Given this, it is essential that all sauna users are able to experience even heating in their sauna. This will help enhance the health benefits such as:

  • Promoting heart health
  • Boosting blood flow
  • Stimulating the release of serotonin
  • Increased heavy metal detoxification

Heat distribution also contributes to a comfortable sauna experience for all of the users. Additionally, the more evenly distributed the heat is, the more energy-efficient your sauna will be. 

The Role of Sauna Shape in Heat Distribution

Saunas come in many different shapes, sizes and varieties, and each one may distribute heat differently based on its shape. 

Square or Rectangular Saunas

Square and/or rectangular saunas have perpendicular walls and a wide base. The symmetrical design allows for an even placement of heating elements, ensuring uniform heat throughout the space. The flat surfaces allow the heat to rise rather evenly throughout, contributing to even heat distribution.

Barrel Saunas

As the name suggests, barrel saunas are shaped like a cylinder and have curved walls, floors and ceilings. This shape is mostly commonly used for outdoor saunas. Although this shape looks beautiful, it is also very functional. The rounded shape encourages heat to flow in a circular direction, which naturally distributes heat evenly. The lack of sharp corners minimizes areas where heat can stagnate. Barrel saunas tend to be the absolute best option for even heat distribution.

Pod Saunas

Pod saunas are another popular shape for outdoor use. They appear to be shaped like a rounded triangle or teardrop, with a broad base and narrow ceiling. The rounded ceiling at the top helps direct air back down towards users, allowing for improved circulation. Their compact size also allows them to heat up relatively evenly. 

Poor Heat Distribution

Typically, a sauna will only suffer from poor heat distribution when it has a very wide base. Wide saunas with long rectangular bases tend to have poor heat distribution due to the fact that certain areas are going to be much farther from the heater than others. Avoiding this shape is your best bet if you want to prioritize even heating. 

Opt for Even Heating with a SaunaFin Sauna Kit

Different sauna shapes may impact heat distribution differently. Overall, any symmetrical or rounded shape will make a great choice. If you are looking to invest in an outdoor sauna, a barrel sauna kit is definitely your best bet for even heat distribution. However, if you prefer an indoor sauna, SauanFin offers many cube options that are sure to provide even heating. Contact our sauna company today to get started!
