How to Choose the Right Infrared Sauna Size

Capacity is a useful starting point, but choosing the right sauna is about balancing the number of users, the level of space you prefer and the room available.

Always work from the exact dimensions of your chosen model rather than its stated capacity alone.

Start With How You Will Use It

Think about who will normally use the sauna and how much space you would like during each session.

A one-person sauna keeps the footprint compact and is well suited to a private daily routine.

A two-person sauna gives one person additional room or allows two people to enjoy the sauna together.

A three-person sauna provides more space for shared sessions but requires a larger installation area and more room for delivery and assembly.

Choosing a larger capacity can also be worthwhile if you prefer a more spacious interior, even when the sauna will usually be used by one person.

Measure the Complete Footprint

Once you have identified the capacity you prefer, check the exact external dimensions of the sauna.

Mark the stated width and depth on the floor using removable tape so you can see how much of the room the sauna will occupy.

You should also consider:

• Overall height
• Door opening and swing
• Access to controls
• Ventilation points
• Electrical connections
• Any required clearances around the sauna

Do not assume that two saunas with the same stated capacity will have identical dimensions.

Check the Delivery Route

The sauna also needs to reach its intended location before it can be assembled.

Measure the full route between the delivery point and the final installation area, including:

• External entrances
• Doorways
• Corridors
• Staircases
• Landings
• Tight corners
• Lifts, where applicable

Where packaged dimensions or individual component sizes are available, compare these with the measurements of your access route.

Remember that assembly can require more working space than the finished sauna occupies, so allow sufficient room around the installation area on delivery day.

Consider the Internal Seating

Capacity does not tell you everything about how spacious a sauna will feel.

Look at the internal bench layout, seating position and heater placement when comparing different models.

If the sauna will usually be used by one person, a larger model may provide a more spacious experience where room allows.

If you intend to share the sauna regularly, check that the stated capacity and bench arrangement suit the way you expect to use it.

Confirm the Electrical Requirements

Electrical requirements can vary between sauna models.

Before ordering, check the stated:

• Voltage
  
• Power rating
• Plug or connection method

Use the specifications provided for the exact model you are considering rather than applying the requirements of another sauna within the range.

Where necessary, ask a qualified electrician to confirm that the intended electrical supply and circuit are suitable before installation.

Think About the Room Around the Sauna

The sauna itself is only part of the space you need to consider.

You may also want enough room to move comfortably around the cabin, open the door fully and access any controls or service points.

Consider how the sauna will sit alongside surrounding furniture, walls and other features so the finished installation feels intentional rather than overcrowded.

A Simple Pre-Order Checklist

Before choosing your sauna, confirm that:

• External width, depth and height have been checked
• The sauna fits comfortably within the intended space
• Door opening and required clearances have been allowed for
• The full delivery route has been measured
• Sufficient space is available for assembly
• The floor is level and suitable
• Electrical requirements have been reviewed
• The capacity and bench layout suit the intended users
