2. Use Double-Duty Fixtures 

The Tiny Tack House has one sink that serves double-duty for cleaning both dishes . . . and teeth. This eliminates the need for a separate lavatory sink, but also introduces a need for more immediate and thorough cleaning. One thing I don't see in any of the pictures is a mirror near the sink, which is something I couldn't live without. I gotta check my look before rolling out to work or a night on the town! Some things we do not skimp on.
