From a construction standpoint, doors that don’t extend to the floor are less expensive to manufacture and install. There’s no need for precise floor measurements or adjustments for uneven surfaces, and the hardware requirements are simplified. This cost savings can be substantial when outfitting large facilities with dozens of stalls.
The gap also reduces wear and tear on door hardware. Doors that don’t scrape against floors last longer and require less frequent adjustment or replacement, reducing long-term maintenance costs.
