Just caught an episode of 'Bath Crashers' on DIY network where they used a '72 or'73 CB 450 as the vanity for a double sink. The rest of the bathroom consisted of an indoor/outdoor shower, bar with fridge, and a 55" TV behind the mirror! Definitely not something my wife would let me get away with!

I tried looking for a photo of the finished vanity but could only find a picture of the bike with the stand welded to it, before the tank and sinks were added.
