Top 5 Mistakes People Make When Buying a Sauna

August 14, 2025

Shopping for a sauna is exciting—but it’s also easy to overlook the details that make the difference between a great investment and a frustrating one. To help you avoid buyer’s remorse, here are the top 5 mistakes people make when buying a sauna—and how to avoid them.

1. Choosing the Wrong Size

Too big and you’re wasting space (and heat). Too small and you’ll feel cramped every time you try to relax. Think about who will use the sauna regularly—just you, or your whole family? Measure your available space carefully and account for both exterior and interior dimensions.

2. Ignoring the Heater Type

Your heater is the heart of your sauna. A cheap or undersized heater will struggle to reach temperature and wear out faster. Always match your heater to the sauna size, and choose a trusted brand like HUUM for reliable performance and longevity. Electric is ideal for convenience. Wood-fired is great for off-grid setups—but both require proper planning.

3. Forgetting About Ventilation

Proper airflow makes a huge difference in how comfortable and safe your sauna feels. Without good ventilation, heat can become stifling, and humidity can cause mold over time. Choose a model with built-in vents or plan ahead to add them during setup.

4. Going Cheap on Materials

Not all sauna wood is created equal. Opting for lower-quality wood can lead to warping, cracking, or mildew. Look for naturally rot-resistant materials like Canadian Red Cedar, which handles heat, moisture, and time with ease.

5. Not Thinking About Accessories

A lot of buyers don’t realize how much better the sauna experience is with the right add-ons—until it’s too late. Backrests, lighting, thermometers, buckets, and ladles aren’t just extras—they’re part of the ritual. Make sure you know what’s included and what you might want to add.
