The splash pools are 12 by 12 feet and from 3 ft to 5 ft deep. There are steps in one corner and a ledge that runs from the steps along one side. ( the side that's nearest to the patio doors usually) The ledge is just wide enough to sit on, maybe a foot wide. The 5 ft deep place is opposite the steps and close to the opposite side. From the steps and along where the ledge is it's about 3ft to 3 and half feet.
