What Size Sauna Do I Need?

Have you decided between an indoor and outdoor home sauna? The next step is the planning phase. What size sauna do you need? Choosing the size is easier than you might think. It all comes down to how many people will use it, where you plan to put it, and the type of experience you want.

At Alpine Spas, we offer everything from compact 2 to 3-person saunas to spacious 8-person models, so there’s an option for every home.

Key Considerations

•  Space & Layout

• Comfort vs. Efficiency

• Ceiling Height

• Interior Design

How to Choose a Home Sauna Size

What is the optimal sauna size? The truth is, there’s no single “right” size for every home. The best size depends on how you like to relax and the space you have available.

Compact saunas work well in smaller homes. They take up very little space and heat up quickly, making them easy to use every day.  We also offer compact traditional outdoor designs for three people, available in both traditional and infrared outdoor styles. These are great if you want the outdoor experience but don’t have space for a large cabin.

Smaller sizes are the best option if you're short on space but still want all the wellness benefits of saunas at home.

A medium or large sauna might be a good option if you have a little more space. Bigger saunas work well if you plan to share the experience with family or friends. These models have more seating and legroom.

They work well in home gyms, garages, and larger outdoor areas. A 4–6 person sauna gives you plenty of space without feeling too big. These are a great middle ground for a lot of homes in New Zealand.

For the ultimate at-home spa experience, a large sauna is the way to go. These models can fit up to eight people and create a social, relaxing space for gatherings or family nights.

Extra-large saunas feel roomy and luxurious, and they’re perfect if you want your sauna to be a main feature of your home or backyard. They also give you space to lie down or stretch out without bumping into anyone.

Quick Takeaway | What Size Should You Choose?

• 2–3 people: Best for small spaces and everyday personal use

• 4–6 people: An easy fit for most families

• Up to 8 people: Great for entertaining or creating a full spa experience at home
