It is not easy to find the best flushing toilet. If you find any good, then it price is higher than normal. And Most of the homeowner don't know which toilet is better for performance. Thus, I have written flushing toilet buying guide and tips in my website https://bestflushingtoilet.org/ . Although, it is not easy to select the right one. Because, if you don't increase your budget, then have to compromise with features. Thus, In my website I have combined price and performance of a toilet. I have also added each toilet MAP testing result. So, you will get accurate idea about the toilets. I will not suggest a flushing toilet which use more than 1.60GPF. A few state in the USA don't allow 1.6 GPF or more. The idea gpf toilet is 1.28 or less.
