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.
