Why we recommend it
It is the answer for buyers who want the room to stay elegant. You get real heat-and-recovery presence without turning the whole project into a garden install.

Indoor infrared
A three-person infrared cabin sized at 150 x 100 x 190 cm and rated at 2250W / 13A. Pro-Line positions it as a plug-and-play indoor sauna on a standard UK outlet, which makes it the easier indoor counterpoint to the larger outdoor barrel.

Why it stands out
This is the more architectural option. It stays quieter in a room, asks less of the install, and keeps the category from tipping into pure garden drama.
Setup note
Pro-Line states that infrared units can usually plug into a normal UK socket. That lowers the barrier dramatically compared with the mains-connected traditional steam models.
Warranty and support
The current retailer listing states a 1-year electrical warranty and a 2-year wood warranty, with self-assembly guidance and delivery support.
Fit
What stands outEase
The 13A plug-and-play position makes this much easier to picture as a real project rather than a fantasy install.
What to planRoom prep
You still need enough depth for access, airflow and a comfortable entry path, but the planning burden is lighter than the outdoor steam models.

Need more outdoor presence instead?
The barrel sauna carries more visual force, but it also carries a heavier installation story. Compare both before you commit to a direction.

FAQ
Questions buyers ask before they commit.
Does it really use a standard socket?
That is how Pro-Line currently positions this listing. It is one of the reasons it works so well as the low-friction indoor pick.
How many people fits comfortably?
The retailer positions it as a three-person model, but the real test is whether you are buying for short solo sessions or shared use.
Why choose this over the barrel sauna?
Choose this if you care more about interior harmony and simpler setup than about making the sauna the centrepiece of a garden project.
