EOS Mythos sauna heater in an architectural sauna interior

Presented by Between Living
in partnership with

Sauna engineering, made precise.

German-engineered sauna heaters, controls and ritual accessories shaped around exact heat, architectural restraint and the quiet confidence of equipment built to perform.

German sauna engineering Introducing EOS.

EOS belongs to a German tradition in which engineering is not hidden behind the experience. It becomes part of the experience. Heater geometry, material, stone volume, controls and thermal performance are treated as one precise system.

Across residential and commercial sauna environments, EOS creates equipment for spaces where heat must feel considered, dependable and visually resolved. The collection moves from discreet under-bench systems to sculptural floor heaters, architectural wall-mounted designs and sophisticated control technology.

What distinguishes EOS is restraint. The products do not need visual excess to communicate quality. Stainless steel, anthracite, black and white finishes allow the heater to become either a deliberate object in the room or an almost invisible part of the architecture.

Chosen with intention Why Between Living Chose EOS

German Engineering Discipline

EOS brings precision, material discipline and technical clarity into equipment expected to perform repeatedly in demanding residential and commercial sauna environments.

Architecture Before Ornament

Freestanding, wall-mounted and under-bench forms allow heat to be integrated according to the room rather than forcing every sauna around one heater silhouette.

Residential to Commercial Scale

The collection spans private sauna rooms and more demanding commercial applications, including higher-output heaters for spaces where capacity and repeat performance matter.

Heat and Control Considered Together

EOS pairs heater engineering with dedicated control systems, allowing temperature, operation and system configuration to be treated as part of one complete sauna environment.

Material That Belongs in the Room

Stainless steel, anthracite, black and white options allow selected EOS heaters to coordinate with the architecture instead of visually fighting against it.

Precision in Service of Ritual

The engineering ultimately serves something human: reliable heat, stone, steam, scent and time enough for the body to settle into the sauna ritual.

Heat becomes architecture.

Let it become a sculptural presence, sit quietly against the wall, or disappear beneath the benches.

Selected configurations are available in stainless steel, anthracite, black and white, allowing the heater to become part of the sauna's visual language.

04 · Give the heat its intelligence

Heat is only part
of the system.

EOS control technology connects the heater to the way you actually use the sauna. Choose the control experience first, then confirm the correct power configuration for the heater and electrical supply.

A simpler way to understand the system

Control. Connect. Heat.

Think of the system in three quiet layers.

01

Choose the heater

Begin with room size, desired placement and the EOS heater family that suits the sauna.

02

Choose the control

Select the interface and level of control that make sense for the way the sauna will be used.

03

Confirm the power path

The exact relay, power-box or extension requirement depends on the heater, output and electrical configuration selected.

05 · Control the ritual
