People find the idea of going without toilet paper a bit shocking, but lots of people around the world do it, and there are good technologies available now to replace your toilet or add on to it. It is cleaner and healthier, and counterintuitively, saves a lot of water. Making a roll of toilet paper uses 1.5 pounds of wood, 37 gallons of water and 1.3 KWh of of electricity.
A lot of these bidet style toilets are expensive, as are may of the toilet seat add-ons. The Blue Bidet is only US$ 69, C$79 when I saw it at the local Home Show in Toronto.
Peter Gallos tells me that it can be installed in under half an hour. They make a cold water model that just uses the line that supplies the toilet, and a version that uses hot and cold water but needs a more elaborate installation. I wondered if our 40 degree F water would not be a bit of a jolt to the butt, but he says it is such a short blast that it isn't a problem. TreeHugger Justin tried one earlier and wrote in his post Bidets: Eliminate Toilet Paper, Increase Your Hygiene:
After using a bidet, most people find cold water is fine, and not particularly shocking on one's rear. Occasionally, a few sheets of paper are needed to dry oneself. To avoid this, you could get a air-drying bidet that would eliminate toilet paper entirely.
Interestingly, Blue Bidet does not say that they are eliminating toilet paper, just cutting its use by 75% and using the remainder to dry yourself off. Perhaps it is too hard a sell to say you don't need any. I will give the thing a try and let you know.More on the Blue BIdet in the USA and in Canada
