A steamy, well-lit bathroom is the perfect spot for almost ALL house plants. Lots of house plants tend to be from tropical spots like rainforests with high humidity and the steam from your bath/shower will be a fab replacement for this. The only plants that aren’t too fussed with humidity are succulents and cacti. Whilst they’d generally be fine out of reach on a shelf, we’d recommend putting them in a place where they’d get wet.
