Seen all over the world and emerging as a favorite in the US. Dual flush toilets are saving water and money everywhere. They are pretty much the standard in Europe and are Mandatory in Australia and Israel, dual flush toilets are the best toilets for saving water. These toilets are the leading the way in water saving toilets buy having two different flushes. A full flush 1.6 gallons for flush and a half flush 0.8 gallons per flush. This option lets the user the choice every time he or she goes.
I have received the question many times. Depends who you ask especially if they work for the many toilet manufacturers. In my mind the best toilet for the home is of course a water saving toilet. I particularity favor any high efficiency toilet. They can save some serious water like over 10 thousand gallons of water per year. Now the rest is up to you. If you have a small space I would suggest a tank-less toilet which means the tank is installed into the wall. The tank-less toilet saves space by eliminating the tank. There is also the corner toilet if you are confined to a corner of the bathroom. This type of toilet has tank that is shaped on ninety degree angle so that it fits into the crevasse of your wall. If you are interested in the way a toilet flushes there a two major options there is the siphon and the gravity flush. The gravity flush uses the water's natural pressure to flush the waste. the siphon flush works by using suction to suck the waste when the toilet is flushed. Siphon flush toilets are little bit louder than the a gravity flush toilet. Hopefully this will help you to decide the best toilet.
