Verily, as so many things are not birdhouses. The overwhelming majority, in fact.

But it looks like it might want to be a birdhouse, yes? This cannot be said of most things.

Fact is that it is to be a soap dish. You can see the soap dish that it will replace on the right. The old one was pine on the bottom and cedar on the side. This is teak on the bottom and red birch on the sides. The key design improvement is the orientation into the corner. The old one wanted to pull off the wall. This one will resist that inclination as it anchors on two walls. Wood joined with dowels. Impervious to rust.

There it is, deployed. MTBF perhaps 5 years.
