All of the wading pools I have ever seen in over 20 years in the swimming pool business are very small compared to swimming pools. A wading pool is typically for small children. In general the pools are one foot or less in depth and anywhere from 6 feet to 10 feet circular or in a square. You cannot swim in a normal wading pool. A swimming pool generally starts at 2 and 1/2 feet to 3 feet in depth and goes to 6 feet or 8 feet. You can swim in a swimming pool because you have enough depth of the water to do so.
