A small bathroom, the Japanese way

A typical Japanese bathroom is about the size of a tatami mat, and nobody in Japan considers this a hardship. The room works because everything in it earns its place, does its job, and then gets out of the way. That mindset packs flat and ships anywhere.

Water goes in basins

The wash basin is the quiet workhorse: soaking a shirt collar, holding the hand-wash cycle, catching drips under a fixed faucet. It hangs on a hook to dry, which is the entire trick; a basin that lives on the floor collects grime, a basin on a hook is always clean and never underfoot.

The foot bath is the one luxury in the line, and it costs less than a takeout dinner. Warm water to the ankle line at the end of a long day of standing; the high wall keeps the warmth in and the splash off the floor.

Everything else goes vertical

Floor space is the scarce resource, so the walls do the storing. Racks that hold a sponge above the sink line, hangers that carry small laundry over the tub, cases that stack soap and spares straight up. When the floor is clear, a small bathroom cleans itself in four wipes.

None of this asks for a renovation. Pick the corner that annoys you most and give it one piece with one job; the room gets the idea from there.
