I wanted a mud room in the worst way but had no space for one. Since we always use the garage entry I came up with the idea to convert the closet by that entry into a mud room. We removed the bifold doors & built in the entry with molding. I found those baskets and hung one on each side. Then we hung crown molding & used the board that supported the self as railing for the cost hooks. There's a boot tray on hidden on a black rug under the bench. So when you look down the hall, this just looks like a room not a closet. We don't miss the closet at all and use this space all the time now. Molding detail:

I love the whimsy of the wall paper. To me a laundry room should be fun as the activity that takes place there, often isn't. The carrera marble is so neutral, you may not need tie it in at all, and the kitchen is far enough away that you can be more independent in the laundry. In my case, it is right off the foyer, but I went with a fun color anyway. It's hard to know what would work as "goldish" and "brownish" isn't very specific. Perhaps if you posted a pic just so we could see the colors you're working with. I also suggest visiting design-seeds for some ideas. You can either search for the color or just scroll through the images until you find a color of interest, then you can select it to see other color schemes that use that same shade. It's fun to play with. Here's one scheme that combines the browns and gold tones with the grays. Here is a link that might be useful: Design seeds

My laundry room is only that; it's not a mud room or utility room. I have lots of shelves - hub built most of them and installed them. There are huge hooks he installed for me to hang clothes on (I hang and fold clothes as I'm taking them out of the dryer). He also installed a nice rod/shelf above the dryer so that I can hang or lay things there to air dry. Other than machines, hooks on the wall, and shelves, I have lots of laundry detergent, a jug of vinegar, a huge jug of fabric softener (one lasts more than a year), a box of OxiClean and Color Catchers for when I combine colors in a load (I don't do that often, but I have a thing about only washing full loads). And a tall kitchen size trash can which seems to stay full - I haven't figured that out yet. Mine is very utilitarian, but it works for me and is in a very handy location.

Mom of seven here. We farm which means everyone has two full wardrobes of everything: Farm and Town. I have some quick ideas for you, no time to be diplomatic sorry. You need to purge. Dozens of hats are not necessary for six people. Choose two each: one light weight beanie and one really warm toque. Ditto mittens/gloves: one lighter weight for dashing to the grocery store, one heavy pair for skiing etc. Each person's stuff will fit in one basket. No one needs more than one pair of Crocs or flip flops. Those can go on a shoe rack by the door. Put a towel hook over the closet door, that's where everyone can store their towel. Colour coding avoids fights: Payton can't say that Blake stole her towel if hers is yellow and his is green. Bathing suits can be stored where they change. Check out the rental area at your local ski hill. Recreate that storage situation with one set of boots and skis for each. You mentioned that this kind of equipment is stored outside but: I see ski boots! Where you have a hanging rod, instead install a pullout clothes drying rack. Put one over the laundry sink too. The white organizer looks disfunctional in that it seems stuff can tumble out easily and it's too hard to see what's at the bottom of each bin. A basket or drawer on a bench is best in my experience, those cube organizers are ok too but then they have to pull a drawer out and hold it while they search. Instead I would put a deep bench or two under the hooks and set baskets on it. A coffee table actually works well for this. Put boot trays in front of it to catch drips. The hooks are too high for anyone under twelve to reach independently. Lower them for the kids. Add shelves above them. Having said that, I don't see any toddler stuff here. Time for peeps to get responsible.
