Stones

Delivery
This stove ships by freight on a wooden pallet, protected in three-ply cardboard, and the carrier will call to arrange a delivery appointment. Delivery is to the kerb — the driver is not responsible for moving it inside or for assembly, so plan for a second pair of hands. Sauna stones and accessories ordered with the stove ship on the same pallet, which is normally cheaper than ordering them separately.
