The invention relates to a stable floor construction for horse husbandry, particularly for horse stables with boxes, freestanding horse stables, horse trailers and horse transporters, erected in five superimposed planes which are geometrically equal in area and consist of different materials. The sealing plane (1) is the lowest layer and is arranged on a slope. The supporting plane 2 (= grid plane) has a built-in flush line (6), an admission for the flush line (7), a flush hole (8), a discharge channel (9), an outlet or a recess for removal by suction if an outlet is not possible for structural reasons (10), and built-in drainage channels (11). The screen plane (3) is arranged above the supporting plane (= grid plane; 2), followed by the damping plane (4) and then the bedding plane (5). This stable floor construction allows horse urine to run off autonomously into the outlet provided therefor such that the cleaning of stables is significantly simplified and economical, ecological and health-hazardous disadvantages for humans and animals are also eliminated.
