Waterworks would not give even a ballpark quote for a simple toilet installation over the phone. When the plumber got here, he told me (reading out of a book that the telephone person could have consulted) it was $548 (I had already paid for the toilet). I wanted it done, so I paid the outrageous rate for an hour's work. Now the plumber was professional and did an excellent job, but I feel royally ripped off. The plumber claimed Waterworks's competitors charge the same, which would make OPEC look like CARE. I should have refused at that price, but I foolishly didn't. Bottom line: shop around. Get a good handyman who charges by the hour, because it's an easy installation. Should be closer to $150 than $548.
