How to choose the right sauna for your home – and avoid the 3 most common mistakes people make

Hvordan velge riktig badstue til hjemmet – og unngå de 3 vanligste feilene folk gjør

It's easy to be tempted by a pretty picture, but the perfect sauna is about far more than appearance.
It should suit your room, power capacity, climate – and not least, how you actually use it.

At NorthSauna, we help homeowners and cabin owners find just the right solution every week – without stress, misunderstandings or wrong purchases.


1. Wrong size – the most common trap

Many people choose a sauna that is too small because they think "two people are enough."
The result? Too little power, poor circulation and a cramped experience.

➡️ Rule of thumb:

  • 1 m³ of sauna volume requires approximately 1 kW of heater power.

  • Also remember the ceiling height – it greatly affects heat distribution.

NorthSauna helps you calculate the correct size based on how many people will use the sauna, room type and desired heating profile.


2. Wrong type of sauna for the wrong location

Not all saunas can withstand the same conditions.
This is the difference many people don't know about:

Location Recommended type Important considerations
Indoor Prefabricated or site-built sauna Ventilation and moisture protection
Outdoors Barrel sauna or modern thermowood model Insulation, snow load and foundation
Cabin without electricity Wood-fired sauna Pipe location and safety distance

At NorthSauna you get both – ready-made indoor modules and robust outdoor saunas in Thermo Aspen and Thermo Alder.


3. Forget about electricity and foundations

Power and substrate are two points that can ruin an otherwise perfect project.
Before you order:

  • Check that you have the correct fuse size for your selected oven.

  • Ensure a firm and level surface – preferably concrete, a terrace or a solid gravel layer.

We always provide you with a simple guide for pre-delivery preparation so that everything works seamlessly.


The right choice = better experience and higher value

A correctly sized, correctly positioned and correctly installed sauna provides:

  • Shorter warm-up time

  • Lower power consumption

  • Longer lifespan

  • Better comfort

And most importantly – it looks amazing, year after year.
