## Customer Reviews

### ⭐⭐⭐⭐⭐ Currently have the same model in our other bath.
*by R***  on June 23, 2025*

Quality toilet

### ⭐⭐⭐⭐⭐ sit down without knee pain
*by P***L on May 3, 2020*

I like it because it is a very large bowl, and it is high enough to make sitting easy, it flushes fast and completely. The only problem I had, was the china caps that go on top of the closet bolts were in the box with the water tank. I installed the bowl first, and I had to take the nuts off the bolts to put the caps on, when I found them, but that was not a hard thing to do. It would make sense to put the bolt caps in the bowl box.

### ⭐ Kohler is great, Amazon is NOT (read below)
*by M***Y on March 22, 2022*

Ok. So I purchased a couple of these from Amazon and one of them had a small crack in the bowl that led to a constant dripping sound diagnosed by my plumber which took some time to figure out. Still dripped even with the tank removed (process of elimination).Called Kohler customer care and they quickly authorized to replace not just the bowl but the entire 2-piece unit under warranty. Kudos to Kohler. They issued me a warranty replacement letter (Kohler Letter_Warranty Replacement without Return) and asked that I provide that to Amazon customer service to have them replace it under warranty. The letter references my receipt, the model and authorizes the shipping of a new unit. Even spells out the Amazon/Kohler replacement credit process - (DISTRIBUTOR PARTNER: Please contact your dedicated Kohler Customer Service Team for inquiries related to the fulfillment of a warranty replacement order.)So after searching and finding the support chat option on Amazon customer care, Amazon would not accept the letter and replace the unit. They did say that they would refund the original cost if I wanted to rebuy the unit which is much lower than what the unit sells for today. At one point I had Kohler customer care on the phone and chatting online in a chat window with Amazon. Both were digging in their heels on how the unit should be replaced but then the Kohler Rep authorized just a bowl replacement using freight shipping and mentioned that I should not buy Kohler from Amazon but rather just call them directly in the future and that Kohler can discount if needed.Amazon - please pay attention to your manufactures and their established support / warranty processes that have been developed to help the customer. It sucks when it falls on me, the customer, to figure out how to diagnose and replace defective items. Be a good reseller or don't be a reseller at all.
