Common Sauna Buying Mistakes to Avoid (2026)

Buying a sauna is an exciting investment — but in 2026, many homeowners still make costly mistakes that lead to poor heat performance, high energy costs, or even returns and replacements.

This guide covers the most common sauna buying mistakes and how to avoid them, so you get the best possible sauna experience from day one.

Mistake #1: Choosing the Wrong Sauna Heater Size

This is the #1 mistake by far.

What goes wrong:

• Heater too small → slow heat-up, weak steam

• Heater too large → harsh heat, wasted energy

How to avoid it:

• Calculate sauna volume correctly

• Account for glass, stone, and outdoor exposure

• Follow proper kW sizing rules

Mistake #2: Ignoring Indoor vs Outdoor Requirements

Many buyers choose a heater designed for indoor use and install it outdoors.

Why this is a problem:

• Outdoor saunas lose heat faster

• Cold weather requires more power

• Incorrect sizing leads to poor performance

The fix:

• Always size one level higher for outdoor saunas

• Choose heaters proven for outdoor environments

Mistake #3: Underestimating the Impact of Glass

Glass looks beautiful — but it absorbs heat.

Common issues:

• Large glass doors or walls reduce heat efficiency

• Heater struggles to maintain temperature

• Users blame the heater instead of the design

Best practice:

• Add extra power for glass surfaces

• Limit unnecessary glass in cold climates

Mistake #4: Choosing Price Over Performance

Trying to save money upfront often costs more long term.

Typical results:

• Shorter heater lifespan

• Uneven heat

• Higher energy usage

• Need for early replacement

Smarter approach:

• Invest in proven sauna heater brands

• Choose reliability and heat quality

• Focus on long-term value, not just price

Mistake #5: Not Thinking About Heat Style & Comfort

Not all sauna heat feels the same.

Buyers often forget to ask:

• Do I want intense traditional heat?

• Softer, longer sessions?

• Even heat from floor to ceiling?

Different heater designs produce very different experiences.

Mistake #6: Overlooking Control Options

In 2026, control systems matter more than ever.

Common oversight:

Recommendation:

• Digital or smart controls increase usage and satisfaction

Mistake #7: Forgetting About Electrical Requirements

Some buyers discover electrical limitations after purchase.

Common issues:

• Inadequate electrical supply

• Need for panel upgrades

• Installation delays

How to avoid it:

• Check electrical capacity early

• Match heater power to your home’s setup

• Ask before ordering

Result:

• Poor first experience

Best solution:
