Instead of trying to cause Maria to suffer with pain, they're going to try and make her break by weakineing her in the sauna. Maria lies with her wrists roped up and attached to the chamber, her ankles are cuffed and her mouth is gagged so she can't complain about her predicament. And then they turn on the heat.

They don't just turn it on to the max, they slowly let the temperature rise. Maria is alone, helpless to escape from the heat and humidity as it rises. Will they ever come let her out, or are they just going to wait until the heat overcomes Maria completely.
