I think it is human nature that in the bathroom nothing is ever returned to its proper place in the cabinet or drawers. Everything has a place on the counter. Well it looks kind of messy so I decided to try to organize just a bit. I figured that if a person is OK with laying something on the counter they might actually put it in a designated slot if their arm movement was the same as before.
So I just came up with a simple box that is 22" long and 7" wide and it contains 12 cubby holes or slots of varing sizes. Two have holes in their tops to put toothbrushes and razors. By the way since I live in a 60+ year old home that has never been updated the original toothbrush holder will no longer hold modern toothbrushes.
The picture can give you some idea of how it is supposed to work.
I took 1x4s from the scrap pile and re-sawed them using a band saw to produce a number of fairly thin (about 5/16" ) thickness boards. Then through trial and error plus a lot of measuring of toiletry items I came up with the final product. The size of the box and the internal cubby holes and slots are really just a guess in hopes it is functional. It is held together with Tightbond II glue and some copper nails in strategic locations.
