### ⭐⭐⭐⭐⭐ 







  
  
    Perfectly fit my Kohler Rosario one piece toilet
  

*by W***L on Reviewed in Canada on 25 April 2024*

Part was exactly as ordered, arrived as promised. Perfectly fit my Kohler Rosario toilet. Installing the part was difficult because the replacement gasket is very thick and needs to be compressed to half its size to properly install. I resorted to what I found on the internet; soak with water, put a small board on each side of it, clamp it down with 2 clamps so it is half the size; freeze it for four hours; take clamps off and it will install easily with it being compressed from the freezing. Half an hour later it thaws out and seals perfectly.
