A mud room or mudroom is an area built into some houses to act as a barrier between the outdoors and indoors. Especially in regions with wet, muddy winters, this type of small, specialized room can be a useful addition as it helps to keep the house clean. In addition, it constitutes a clear boundary between indoors and out, which can be a useful reminder for animals and exuberant members of the household.
Generally, a mud room has easily cleaned floors made in materials like tile, concrete, or linoleum. In extreme cases, one may even have a drain in the floor to make sluicing the floor very easy. A well designed room also has ample hooks and racks for damp, wet clothing, as well as racks or cubbies for shoes. In addition, benches for people to sit on while they remove their shoes are not uncommon. All of these measures are designed to encourage people to remove sodden or dirty layers before entering the house.
