The Los Angeles Times takes a look at bidets that can be fit onto existing toilets.
With the introduction of high-tech bidet seats that can be retrofitted to existing toilets, products such as Toto’s Washlet and Brondell’s Swash are gradually becoming standard equipment in high-end homes.One of the selling points: environmental friendliness. Though the bidet does increase water usage slightly, it can reduce the use of toilet paper by 50% to 90%, according to Brondell. That may not seem significant until one realizes that Americans use more than 3.2 million tons of toilet paper annually, cutting down 54 million trees in the process. The production of each roll requires an average of 1 1/2 pounds of wood, 37 gallons of water and 1.3 kilowatts of energy, and it involves toxic chemicals such as chlorine.
