We don't have a real mudroom so to speak, despite our whole house reno 2 years ago (read all about that here). We have what I call a "mud area" which is the landing on our stairs in front of our driveway door which is the main every day door in our house now. We have a small set of hooks there (from Target), and a boot tray (also from Target) to organize the space.
The rug is a "water hog" from LL Bean. I love that it's big enough to cover and protect most of the wood floors. Well worth the investment even though I would have liked something with a bit more color and interest.
Of course the mess on the boot tray was driving me crazy. Not much I can do about the boots and shoes that live there. At least they are contained on the tray! (more on my tray obsession here)
So, how much was my "mud room"? Here is how much I paid for my stuff but I gave you some suggestions in case you want to recreate a similar area in your home. Note: The prices aren't the same because the products I purchased don't seem to be available any more.
Set of Hooks (similar to this) - about $25
Boot Tray (similar to this) - about $30
Mitten Box - $8
Water Hog Mat (find it here) - about $75
TOTAL - about $140
Well worth it to keep the coats and boots off the kitchen floor!
