The most common kitchen counter height is 36 inches, but it can vary from 30 to 45 inches. The standard kitchen sink is 8 inches deep, which means that the normal distance between a kitchen sink drain and the floor is 28 inches. This will vary, depending on the height of the counter and the depth of the sink bowl. In the bathroom, the sink drain is typically between 24 inches above the floor.
Best Answer: I recommend that you prepare a 12 inch wide drain at least 12 inches deep and at least 20 long to be effective. These are called trench drains, french drains or yard drains.Be sure to use at least a 1 inch washed gravel @ 8 inches deep and then cover it with straw before you put the 4 inches of dirt back over it.
