All our counter technically has on it is the kids' battery toothbrushes and one small bookrack/bookholder with first-aid/herbal/homeopathy/health type reference books. (DH's and my toothbrushes are in a wall holder that also holds a cup, and there is a wall holder soap dish and hand towel rack as well). Our tiled countertop is quite large; it could fit two sinks but we have only one. It is nearly always clear unless the kids leave a towel on it or something.
All that is around my tub is the kids' shampoo/conditioner and DH's/my shampoo/conditioner, so four bottles, though when DH's shampoo runs out we'll only have three: family shampoo, kids conditioner, adults conditioner. There is a wall soapdish and I do keep a loofah for cleaning the tub with.
On the back of the toilet is a small rectangular basket with several books in it.
We have a linen closet that has toothpaste and floss, towels, first-aid, EOs, DH's shaving stuff, a basket of misc stuff, and the cleaning stuff I use in the bathroom, plus two baskets down below - one of mama pads and one of cloth wipies.
We also have one drawer that has hand towels, handkerchiefs, and hairbrushes. Under the sink is washcloths, bathmats, trash, and recycling.
That's it!! I am proud to say my bathroom is the least-cluttered room in the house.
