Where the name comes from
KOS stands for Kocham saunę
That's Polish for “I love the sauna”, and it says it all: to us a sauna is not just a product but a way to unwind. So we give the advice we would give our friends — we match the stove to the room volume, the chimney to the stove, and the sauna to the spot where it will stand.
A shop for sauna equipment
Wood-burning sauna stoves and electric sauna heaters, chimneys, hot tubs, sauna doors and windows, timber and materials. We work with Harvia, Teplodar and Narvi. We order goods from the supplier once you place your order, which is why every product shows its shipping time.
Saunas and hot tubs, built for you
We design and build custom saunas and install hot tubs anywhere in Poland — from the first consultation and choosing the stove to installation and the first fire.
