Description

Handcrafted in Estonia by COZY Heat, the Quattro Thru-Wall sauna stove merges traditional sauna-building craftsmanship with practical design. It's through-the-wall configuration lets you load firewood from outside, while the 5mm stainless steel flame cutter ensures lasting durability. The wood-burning design delivers gentle, sustained heat ideal for creating authentic steam when water meets hot stones. Clean minimalist lines and an expansive viewing window showcase the flames' natural beauty, adding visual warmth to your sauna space. Built for those who value both performance and aesthetic refinement in their sauna experience.
