Perhaps you're among the 30% of AT:SF readers
who have one of those tiny separate water closets? Environmental Designworks' SinkPositive
is perfect for tiny bathrooms, even more so if you're going green: used water drains into the toilet tank and has a second go-around when you flush.
We see this as a space-saving substitute for a regular sink in a tiny bathroom, so long as it's not the primary bathroom (can you imagine washing your face or shaving over a basin so small?)
Also recommended for those who are lazy about washing hands after using the loo. As with making it to the gym on a regular basis, proximity (of the destination) is everything.
Sinkpositive is $99 and available here, with shipping free until April 21st (Earth Day).
