I am installing 2 new toilets in a few weeks and had a few questions. First we are looking for a round bowl and standard size toilet as both bathrooms are on the smaller size. I am very confused on pricing. How come everything consumer reported rate is around $300 while when I walk into Home Depot or Lowes toilets are anywhere from $100-$500? Lowes and HD flush performance is rated on golf balls, how reliable is that? I was hoping to spend less than $300 a toilet but if a cheaper toilet would perform just as well then why wouldn't I get that? We have really old (80's) American Standard toilets and are still performing ok (although we do have the ghost flush) but I want something that will perform very good while helping the environment. Please help!
