Felt good to see it bead up and stay in place to get wiped up by a towel. We went with Boiled (aka supremely jiggered with the addition of metal oxide catalysts to accelerate drying) Linseed Oil as opposed to raw because we couldn't find any for a reasonable price locally, and because we were kind of sick of pooping in the bedroom so we got impatient.
Here's another bad photo of our plank wall. If you think about it for more than 5 seconds, you might come to the conclusion that putting the wood right next to the bathtub was a bad idea. Possibly. We did so because we got to install fun shelves and hooks, and I'm hoping that the linseed oil combined with the woods ability to "breathe" a certain amount of vapor will not produce massive failure. Again, like the floor, if we have a problem here we'll disassemble the tub drain, remove the wall and reconsider. For now things seem nice though.
