Overview

When an off-the-shelf cabin will not fit the space or the brief, Helix designs and manufactures the sauna from scratch. Any footprint, any layout, premium Thermowood throughout, barrel, cube, panoramic glass or a room built into your existing structure, for home or commercial use. We survey the space, design it around you, then build, deliver and install it as one team, so you get a sauna that fits perfectly, looks the part and delivers the full Finnish heat experience at 80 to 100°C.

The research

What the science on sauna use has found

Cold and heat are the two anchors of a serious recovery offer, and heat is the one people use again and again. A bespoke Helix sauna gives you the full traditional Finnish experience — deep dry heat in a cabin built to your exact space rather than one your space has to accommodate. Regular sauna bathing is among the most studied rituals in longevity research; the figures below are population-level findings for sauna use in general, shown for context — not outcomes promised by this or any single product.

63%
lower risk of sudden cardiac death among the most frequent sauna users in a long-running Finnish population study
Observational finding for regular sauna bathing — not a claim for this product

Inside the technology

The engineering, in detail

01

Built to your exact size

No fixed dimensions. We design around your floor space, ceiling height and capacity, from a two-person garden cabin to a commercial suite seating twenty.

Built to your exact size — Helix Signature — Bespoke Saunas
02

Any form or layout

Barrel, cube, corner, panoramic glass front, L-shaped benching or a sauna built into an existing room. The geometry is yours to choose.

Any form or layout — Helix Signature — Bespoke Saunas
03

Premium Thermowood throughout

Built entirely in dimensionally stable, heat-treated Thermowood, finished to match your interior or your landscape.

04

Floating benches, built to stay clean

We design our benches to float, cantilevered off the wall with the floor left clear beneath them. Boxed-in benches trap moisture and debris and make the floor underneath impossible to clean properly; floating benches keep the room genuinely hygienic, and can be softly lit from below.

05

Heater specified to the room

Harvia and other premium heaters sized precisely to the cabin volume and expected throughput, electric or wood-fired.

Questions, answered

Good to know

Can you really build any size?+
Yes. Because we design and manufacture in-house, the sauna is built to your exact footprint, height and capacity rather than forcing your space to fit a standard cabin. We start from your dimensions and your brief.
What shapes and styles can I have?+
Barrel, cube, corner, panoramic glass-fronted, bench layouts to suit, or a sauna built into an existing room. We help you choose the form that suits the space and the look you want.
Which timber and heater do you use?+
We build in premium Thermowood throughout, dimensionally stable and heat-treated for sauna use, with a Harvia or equivalent heater sized to the cabin volume, electric or wood-fired. We specify the heater around your room and expected throughput.
Do I get to see the design first?+
Yes. We agree a layout and a visual up front, so you know exactly how it will look and sit before we manufacture anything.
Can it go outdoors, and is it built for commercial use?+
Both. We build for indoor or outdoor placement and to commercial-grade durability for high-traffic gym, spa and hotel settings.
How do delivery and installation work?+
Helix handles the whole journey: survey, design, manufacture, delivery and professional installation, with one team as your point of contact and aftercare afterwards.

What our customers say

Rated 4.6 out of 5 across 40 Google reviews.

★★★★★

Amazing products. The ice bath and chiller we use daily, and honestly one of the best life purchases we have ever made. So impressed we bought the outdoor sauna too. Great products and an amazing team.

Paul M.Google review
★★★★★

Purchased a cold plunge back in 2024, one of the best purchases ever alongside my sauna. Climbing in first thing in the morning, or after a hard bike session, there really isn't much that compares to the boost you get from it.

From submitting our order through to post-installation communication, everything has been excellent and made the whole process run smoothly.
