The cabin feels refined and easy to integrate, with a simple visual language that works well in modern bathrooms, gyms and wellness rooms.
EXPERIENCE

Light alder throughout the cabin with insulated construction
In the Aisti line, light alder is used outside, inside and on the benches, creating a calm and coherent Nordic look. The insulated construction helps maintain comfort and thermal stability during the session.
Free service
Fit check before ordering
Send measurements or images of the space and we will help confirm the base, access and placement.
Complete your hot-cold ritual
Pair your sauna with an ice bath to create a balanced contrast routine: deep heat, clean cold, recovery, repeat. We will help you choose the right combination for your space.
Cube ice bath↗
A compact square ice bath for clean, simple contrast routines. Easy to place outdoors or in a dedicated wellness area.
Ofuro ice bath↗
A roomier oval ice bath with space for two people. Built for deeper immersion, shared recovery and a softer outdoor presence.
Not sure which ice bath fits?
We can help match the sauna, ice bath, placement and usage sequence for your space.
A clear path from order to first session
Before your sauna is confirmed, Saunamo helps review the key details: placement, access, base or room requirements, heater setup and installation needs. The goal is simple — you know what is included, what must be prepared and what happens next.
