The toilet is great! However, the shopping experience was horrific! The website should be designed in a way to address possible concerns that a layperson would encounter. Specifically, the buyer should be alerted to the "rough in" dimension before buying. I had to return a toilet because it was a 12 inch rough instead of the required 10 inch rough. Also, the toilet came with connections that were not standard for US plumbing. I call Wayfair and they were not helpful. My plumber had to do a work around to get the toilet hooked up.
Having said that-The toilet looks great and hopefully it works well for a long time.
