Hotel Konke Mar del Plata Spa

Hotel Konke offers spa access to a rooftop infinity pool, a dry sauna, a steam room and showers at its La Perla hotel. A current third-party experience voucher sells a one-person visit on Sunday through Thursday with those amenities included, separate from a room stay. The hotel's own spa page confirms the sauna facilities and 11:00–21:00 hours. Its photo shows the actual Konke wood-lined sauna cabin.
