Overview

The Eldur is a vertical barrel sauna for two, with a distinctive upright form that makes it one of the most space-efficient and striking saunas in the HELIX Heat range. It delivers authentic traditional heat in a footprint that suits compact spaces, and looks as considered as it performs — equally at home as a performance tool or an architectural centrepiece, indoors or out.

The outcomes

What it delivers

The Eldur proves you don't need a big room to take heat seriously. Its upright barrel form stands two people in a footprint most saunas would laugh at — which is precisely what makes it so useful: the same authentic, deep, restorative heat, and the same body of longevity research behind it, dropped into a corner, a courtyard or a compact studio. It performs like a serious sauna and looks like a sculpture, so it earns its space twice over — once as a recovery tool, once as the thing people can't stop looking at.

Questions, answered

Good to know

Why choose a vertical barrel sauna?+
The upright barrel form is one of the most space-efficient ways to install a genuine two-person sauna. If floor space is your constraint, the Eldur gives you authentic heat without a large footprint — and looks striking doing it.
Is it a 'real' sauna?+
Yes. It delivers authentic traditional dry heat at the same 80–100°C as a full-size cabin, so it carries the same modality-level benefits the Finnish research describes.
How many people does it fit?+
Two. It's designed as an intimate, efficient sauna rather than a large communal one.
Indoor or outdoor?+
Both. Its form and build suit a compact indoor room or an outdoor courtyard or garden as an architectural feature.
Who is it best suited to?+
Spaces where floor area is limited but the ambition isn't — boutique studios, premium homes and facilities that want serious heat and a design statement in one.
Any usage cautions?+
The usual heat-therapy cautions apply — pregnancy, some cardiovascular conditions, alcohol. We provide guidance to share with users.
