On Saturday I went for lunch at the excellent Gambas in Bristol (bit pricey, but worth it...) The restaurant is one of a row of modifed containers, along with lots of other food outlets. When your beer intake has reached the point where relief is required, you go out of the door, down the steps and along the back to more modifed containers in which are the toilets. Inside, it was all lined with what looked like tiles with a wood look, but which on closer inspection, turned out to be pieces of OSB, all cut to the same size, (about 30x 60cm), glued to the walls like tiles, and finished with some sort of sealant in order to make them water/splash proof. Has anyone seen this way of using OSB before? Is this just someone being 'creative' or is this an accepted way of using OSB, in bathrooms and toilets?
