Baja step design question for a rectangular pool - baja spans 10 x 6.5 feet and will be 9 inches deep in water depth (15 inches from coping) Pool is 16 x 34 feet with elevated spa. Should second step of baja span width of the pool or be part of other steps so Baja is straight drop which is 3 1/2 water depth (4 feet from coping)? Want to maximize swimming space but also have functional entry and exit from diferent spots kids ages 10 and 13 and two mid-size dogs (18 pounds) Would appreciate input you have for those with baja shelves. Thanks!
