Thank
It's made in beech, and the sink is porcelain. It's fully waterproof, as it's treated first with a transparent black paint (not paint, but i don't know the english term. It sinks into the wood, not covering the structures) and further more it is coated with three layers of
linseed oil, and polished.
It's handmade, through and through, by me
Sorry, but i used to have a little website with some pictures of recent projects, but i deleted it.
