I love when mudrooms serve multiple purposes.
This one has plenty of space for the whole family to pile into the house at once.
It also is easily accessed from the backyard in case someone is out swimming and needs to go to the bathroom (and the flooring would be water resistant as well).
Plus, this is where you can easily access the bonus room above the garage.
If it were my home? I’d add a dog wash so the muddy dog doesn’t have to be carted all the way through the house to the main bath tub. Perfection!
