Bringing your bathroom to life is an endeavour filled with questions about water! Using brick slips in your bathroom can really elevate the space to something beautiful. Brick soaks in water though, so you do need to think a little bit first. Most locations in the bathroom this actually isn't a problem, it's only directly in a shower or bath backdrop that you need to be sealing them and ensuring there's a waterproof substrate just incase. You can seal the slips wherever in the bathroom though, and it won't affect the look.
