Everyone has to use them, so you might as well make them look great. I am of course talking about toilets.
These are true beasts dedicated to tacky glitz. Sadly, most of these are art pieces with only very few available to the public. However, one can assume if you have the cash to blow on a diamond-studded toilet then paying for one to be made to your tastes won't be a problem.
Many of the toilets above are from Jemal Wright Bath Designs, who has created a process for adding dyes to chrome. Their Chromeosome toilets can be made to match any color, and all come with a flusher in what else but Swarovski crystals.
