This original bathroom furniture is made of recycled cardboard, it allows you to hide the piping of the sink. Each shelf is custom-made by taking into account the piping from the sink. I added a small receptacle on the side that allows you to put the toothbrushes in it. Of course, as it is a piece of furniture that will be exposed to water splashes, I used a waterproof paint.
A nice result at a low cost!
