Both our old and current places had tiny basins in the downstairs toilet and they really are crap. These were so small you couldn't wash your hands properly and if you turned the taps on too high water would splash out and all over the place.
When we were lookng to buy I immediately ruled out any places that didn't have a proper bath. Shortsighted perhaps, especially since I have a bath perhaps once a year, but the wife likes a nice soak and the kids love bath time.
