Finnleo NorthStar Series FAQs
What is the Finnleo NorthStar Indoor Series?
The Finnleo NorthStar Indoor Series is a line of free-standing traditional saunas designed to bring an authentic Finnish sauna experience into your home. These saunas combine Nordic-inspired design, quality materials, and convenient modular construction, making them a great option for homeowners who want a beautiful indoor sauna without building a fully custom room from scratch.
Is the NorthStar Indoor Series a traditional sauna or an infrared sauna?
The NorthStar Indoor Series is a traditional sauna. Instead of using infrared panels, it uses a sauna heater to warm the room and create the classic Finnish sauna experience. This allows you to enjoy higher room temperatures, traditional dry heat, and the option to add water to the sauna stones for bursts of steam.
What sizes are available in the NorthStar Indoor Series?
The NorthStar Indoor Series is available in multiple size options, including compact models for smaller spaces and larger models for families or multiple users. Size options include 4' x 4', 4' x 6', 5' x 6', and 5' x 7', giving homeowners flexibility based on their available space and how many people they want the sauna to accommodate.
How many people can fit in a NorthStar Indoor sauna?
Depending on the model, the NorthStar Indoor Series can seat approximately 2 to 5 people. Smaller models are ideal for solo use or two-person sauna sessions, while larger models offer more room for couples, families, or those who want extra space to stretch out and relax.
What type of wood is used in the NorthStar Indoor Series?
NorthStar Indoor saunas feature Nordic White Spruce walls and ceiling, giving the sauna a bright, clean, and authentic Scandinavian look. The benches and backrests are made with skin-friendly woods such as Aspen or Abachi, which are designed to stay more comfortable to the touch during sauna use.
Is the NorthStar Indoor Series made in the USA?
Yes. The Finnleo NorthStar Indoor Series is made in the USA and built with a modular, free-standing design. This makes it a strong option for customers who want a high-quality sauna with simplified installation compared to a fully custom-built sauna room.
What comes standard with a NorthStar Indoor sauna?
NorthStar Indoor saunas include many of the features customers want in a home sauna, including pre-built wall and ceiling panels, pre-built benches and backrests, sauna heater, SaunaLogic2 control with mobile app functionality, LED lighting, glass door, bucket, and ladle. Specific included features may vary slightly by model.
Does the NorthStar Indoor Series include lighting?
Yes. NorthStar Indoor saunas include LED lighting designed to enhance the overall sauna atmosphere. The lighting helps create a more relaxing, finished look while adding to the comfort and enjoyment of each sauna session.
Can I control the sauna from my phone?

Does the NorthStar Indoor Series require professional installation?
Yes, professional installation is recommended. NorthStar Indoor saunas are designed with modular construction to simplify the process, but they still require proper assembly and electrical work. Most models require a dedicated electrical connection, so it is important to work with qualified professionals to ensure the sauna is installed safely and correctly.
Sauna Safety Tips
Saunas can be a relaxing and beneficial part of a wellness routine, but it is important to use them safely. Start with shorter sessions, especially if you are new to sauna use, and limit most sessions to about 15–20 minutes. Drink plenty of water before and after using the sauna, and avoid alcohol before, during, or immediately after your session, since heat and sweating can increase the risk of dehydration or dizziness. Always cool down gradually after exiting the sauna, and leave right away if you feel lightheaded, nauseous, weak, or uncomfortable. People who are pregnant, have heart conditions, low or high blood pressure, or other medical concerns should speak with a healthcare provider before using a sauna.

Can You Lose Weight by Using a Sauna?
Two landmark Finnish studies — following over 16,000 participants for up to 39 years — found that regular sauna use is associated with dramatically lower risk of dementia and Alzheimer's disease. This guide breaks down what the research actually says, explains the six biological mechanisms that make sauna bathing protective for the brain, and shows you how to incorporate sauna use into a brain-healthy lifestyle.
Infrared Vs Traditional Saunas: What's the Difference?
They both make you sweat — but the way they deliver heat is fundamentally different. Traditional saunas heat the air to 170–195°F and have 20+ years of research linking regular use to lower cardiovascular mortality and dementia risk. Infrared saunas heat your body directly at 120–150°F and have the strongest evidence for chronic pain relief and accessibility. This guide compares both types side by side — how they work, how they feel, health benefits, installation, costs, and a decision framework to help you choose.
How Long Should I Stay in the Sauna for Maximum Benefits?
Stay too short and you won't trigger the health benefits. Stay too long and you risk dehydration. The sweet spot? Research from a 20-year Finnish study found that sessions over 19 minutes were associated with a 52% lower risk of sudden cardiac death. This guide breaks down optimal session length by sauna type (traditional, infrared, hybrid), by health goal (cardiovascular, brain health, sleep, recovery, and more), plus a beginner's progression plan and a complete before-during-after protocol.
