MS4000C Traditional Combi Sauna | Finnish and Infrared, 4 Person

MS4000C Traditional Combi Sauna

A four-person combination sauna in Red Cedar that gives you both heating systems in a single cabin: traditional Finnish hot-stone heat and full-spectrum infrared, switchable independently. The MS4000C is for households where different users genuinely prefer different heat formats — or for those who want the full Finnish experience on some days and the gentler, longer infrared session on others, without buying two cabins.

Finnish mode brings the stone bed to high temperature via the included 6kW heater. Ladle water across the stones and the humidity lifts sharply — löyly, the defining ritual of the Finnish sauna tradition. Infrared mode runs the full-spectrum panels at comfortable cabin temperatures of 45–55°C: body-direct heat, 10–15 minute warm-up, longer and gentler sessions. Both systems operate independently; you choose which to use each time.

Lifetime structural guarantee. Delivered and installed by Medi-Spa's own team, UK-wide.

Frequently asked questions

Can you use both heating systems at once?
Yes, though most users prefer to run them independently — Finnish for a high-heat, löyly session; infrared for a longer, gentler session. Using both together creates a higher ambient temperature with the additional body-direct warmth of the infrared panels, which some users prefer.

Who is a combination sauna for?
Households where different users have different preferences — one person prefers traditional Finnish heat, another prefers infrared — or someone who wants to alternate between both depending on how they feel or what the session is for. It is also the right choice if you want the authentic Finnish experience but also value the convenience and gentler format of infrared for daily use.

Is the löyly ritual available in this sauna?
Yes — when running in Finnish mode, the 6kW heater brings the stone bed to temperature and you ladle water across the stones as you would in any traditional Finnish sauna.
