I have to recaulk my bathroom sink, an infuriatingly small-bowled object that splashes water everywhere yet is astonishingly heavy. It's a solid chunk of porcelain that doesn't deliver good functionality for the amount of matter it consists of, and I dread having to pull it off the wall cleat so I can scrape off the bad original caulking job, which was apparently done while the contractor was having a seizure.
If I had my druthers I'd own Santa-Monica-based design studio Minarc's RUBBiSH, a sink made from recycled rubber.
Melting down old tires is an awesome way to make a sink--not only are the resultant sheets easy to clean, they're only 1/8" thick and can simply be stretched over a form to give them shape, resulting in a super lightweight sink.
