The Bad am Viadukt in Bietigheim-Bissingen keeps a compact sauna area beside its swimming hall: a Finnish sauna at 90 degrees, a Sanarium at 60 to 70 degrees and a Kräutersauna at 85 degrees. Aufguss rounds are performed by the bath's own sauna staff, and a cold cascade shower handles the cooling. Sauna-only tickets cost 16 euros for four hours or 10 euros for two and a half. The bath is shut for maintenance from 24 August to 15 September 2026.
