Basic question on the drywall in relationship to the concrete floor. The floor has a 2x4 around the bottom on the stud walls. I don’t want to bring the drywall all the way to the floor but leave an inch or so up incase water/condensation comes off the concrete. In addition maybe I would want to use water to clean the floor at some time.

Are there any suggestions on what to use to maintain the drywall or keep it from getting wet? Was contemplating putting a plastic surface on it about a foot high but maybe there is a product out there….
