Outdoor Sauna Building Guide PDF in German – Backyard Sauna House, Foundation, Stove, Costs

A 78-page A4 PDF e-book (in German) on building an outdoor sauna in your garden: from permits and foundations to the first sauna session – with 27 figures, 21 building steps, costs at 3 levels and checklists.

Written by a carpenter with hands-on experience. One worked example runs through the whole guide – an insulated sauna house with changing room, 2.50 × 3.50 m – so every dimension, quantity and calculation is concrete. You can repeat the calculations with your own dimensions.

PLEASE NOTE: THE PDF IS IN GERMAN. Legal information refers to Germany.

A guide for orientation, as of October 2026. The building instructions cover the timber-frame sauna house; barrel and prefab saunas are compared as options. The topic is the garden sauna – installing a sauna inside the house is not covered. It does not replace professional planning, structural engineering or legal advice. Electrical connection by a qualified electrician only; wood-fired stoves and flues must be approved by the chimney sweep before first use (Germany). Building law varies by state and country – please check with your local building authority. Costs are guide values. Follow manufacturer instructions and the accepted rules of the art.
