Small Bathroom Problem solving

So in my [new] place, there’s a teensy, tiny little half bathroom off the laundry room. Currently it only houses a toilet because…well…it’s really only big enough for one. Unfortunately there is no room on either side of the powder room to expand either due to the fact that one wall is exterior and the second wall is the stairwell to the basement. I don’t mind the fact that it’s so small necessarily, but I DO mind the fact that it has no sink. That just seems weird…and unsanitary.

So…tonight I ran across a post over at Apartment Therapy about Space Saving sinks and was surprised at some of the interesting options out there. There’s this tiny Block Washbasin by Lacava. It’s really cute, but too expensive at $800+. This tiny corner one by Porcher is also really cool, but I’m not sure if I have a corner in the new house. It’s $325. Much more affordable, but still more than I was hoping for. And lastly, this wacky one that fits on the back of the toilet is super space saving (and water saving too!), but isn’t very aesthetically pleasing. I don’t like the fact that it’s made of plastic and automatically comes on everytime you flush the toilet. Watch the video of how it works here. What do you think? Too weird? Get one of the more expensive sinks….assuming it would actually fit? Or just forego the sink altogether and hope people use the kitchen sink instead?
