As shown previously, the toilet gets its own room, so the bathroom has a sink and our washing machine, and then this room with the shower and tub. Notice how low the mirror is? It isn't for checking how your knees are looking - traditionally, Japanese people would wash themselves first while sitting on a stool (so you would actually be able to see in the mirror), and then get into the bath for soaking after getting clean. The tub is small and deep, and some of the apartments we looked at came with folding tub covers. These would be used to keep the water warm for the other family members that would be getting in after you.
