Smooth surfaces that clean up very easily with no tile joints or other joints to fail. The plan was to use a steam cleaner or power washer to control mold and mildew. This would produce a very easy to clean, durable but difficult to change space. It would look a little sterile.
Then it hit me, while I was laying a patio block outside. The easy care space that I seek doesn't have to be lifeless. Moss, ferns and other plants that thrive in moist, low light conditions are perfectly suited to living in a bathroom. So, it's just a matter of creating the right conditions, without rotting out the building. I'm going to wrap all walls and the floor, in pond liner. The floor will get a double layer that goes up the walls by 6 inches. The wall sheet will be continuous with no corner joints. The wall sheet will lap over the floor sheet and be glued to it. Absolutely water tight, and ugly. The floor will have a drain. The shower or tub could overflow onto the floor with no harm done.
