I have had 3 "Mud Rooms' in my life. Just outside the door to the mud room they had to wipe their feet. Then on a vinyl floor I had a 3x3 mat or depending on the inside door area. I had another mat to store their boots on. These were like car mats. Easy to hose down and dry. It was also the utility room. Never had too much trouble even though there was a lot of traffic. I had couple rubber backed rugs so no slipping.
