Grant makes a good point. Without knowing the source of how the water got into the cabin the problem could happen again the next time you wash the car.
A common source of water in the cabin is backed up body water drains. There are some in the front on either side -- and maybe under -- the battery box. There are two in the back one under each clamshell arm.
Another source can be -- as I recently learned though fortunately I caugh this in time so no damage was done -- leaking door membranes. Both doors were damp along their bottoms and a membrane reseal on the passenger side and a new membrane and proper sealing on the driver side has both door bottoms dry as Death Valley in July.
