What Customers Are Saying

Customers overwhelmingly praise the toilet for its powerful, water-efficient flush, comfortable chair height, and quality construction. Most highlight the strong flushing performance despite low water usage, with many noting it outperforms older models and never clogs.

Impossibly difficult to maintain

The entire thing has to be disassembled to replace the worst riser I have ever seen. Never again will I buy Kolier. I literally have to call a plumber just to replace the flapper!!! What junk

Great service!

Would Recommend

Great toilet and a great shopping experience! The KOHLER toilet looks modern and high quality, and the height is very comfortable. I also had a great experience with Lowe’s pickup. Ordering online was simple, and my order was ready when I arrived. The pickup process was quick and convenient, which was especially helpful with a large item like a toilet. Very happy with the KOHLER toilet and shopped two more orders using the same day shipping!

Beautiful but fill valve already sticking

Would Not Recommend

So this replaced a toilet that had been in my mom‘s house since 1975. This Kohler toilet while absolutely beautiful is already giving me trouble. I bought this thing in March 2025 and it is now August 2026 and the fill valve is already sticking. When you flush the toilet and the tank is supposed to refill you have to slap your hand on the back of the water tank for it to fill. I am beyond annoyed with this. It just floors me how greedy companies have gotten and they don’t care about their produc...
