Not that I am aware of. There are dorm room fridges that may be that size. Have you considered undercounter fridges and freezers? SZ, GE Monogram, Perlick, Summit and the like make different variations on the theme. Fisher and paykel has a 36" wide under counter fridge too. I believe it is just one drawer for fridge storage. The SZ drawers are pretty popular and you can have a fridge freezer in the same stack. Good luck!

thanks for the suggestions brutuses, yours looks great but there are only a couple of tiles on each side. I don't think I would like to do that over a longer stretch of the wall. Chair rail with a border under it would be great, the problem would be finding one that matches. Redroze, what you are describing sounds beautiful, but we are using ceramic tile and most of them don't come with that many options, very few have a matching chair rail. I never thought of wood as a possibility. Now that Bill mentioned wood, I can think that a nice detailed one painted to match the tile, may be a good alternative. Will definitely keep that in mind

I think if you did wood (or in your countertop material since it looks like you replaced that recently?) with a 12"-15" overhang (assuming that half wall is the standard 42" high) for seating, it would look great. This is also assuming you have room on the other side for said seating. Otherwise, just a wood or countertop topper with a bit of an overhand would be fine for a walk up area. Don't know much about tiling, but I'm guessing tiling that area with the edge etc., might not give the best result. Someone here with more tile knowledge may have better advice on that though. It opened up really nicely! Congrats.

If acoustics are your prime concern, you may want to consider adding sound attenuating insulation to the two room walls flanking the stair and hall, making sure that the walls are well sealed top and bottom, that any outlets are sealed around, and that the doors are well fit. A wall next to the stairs, especially without insulation by itself isn't going to do a ton to stop noise transmission as the stair is still open on the ends. Does this stair have an open rail at either side of the main floor, and on which sides (same side as the playroom or the hallway). That will figure into how sound will travel. As with Virgil, I see that there doesn't seem to be any accommodation for a wall in the plan. Was the floor framed so that there is enough thickness to align a wall with the linen closet? And if so, does that make your stairs narrower than they are drawn? From an aesthetic standpoint I would rather have a half wall or open rail. Both hall and stair will seem very closed in and dark without some sense of openess. For that same reason I would seriously consider having a window at the top of the stairs to light the hall and stairs during the day. Otherwise you are going to need to be turning on the stair and hall light every time you pass through there for safety.
