Review: Great Throne! - I received the Kohler toilet and seat (not included) as advertised to replace a shorter, leg numbing toilet with an ever-moving seat that constantly came loose. Uninstalling the previous toilet was the most difficult part. I made sure to save the hardware in case I needed it -- and I did. The new seat was easy to install, but did not come with the t-bolts to fasten secure the toilet to the floor. Not a problem. I also had to purchase a longer (16") water supply line from ACE since the previous shorter toilet had a 12" line that was exactly the right length - for that toilet. This toilet added 1-1 1/2" to the height so it would not reach. Once I had that in hand, the installation went smoothly. I am extremely happy with this combination of toilet and seat. The height is perfect for us and does not cause the legs to fall asleep as the previous one did. In addition, the seat will not move. I can perch upon the throne with complete peace of mind and not worry that it will slip to the side. In addition, the flush is quick, efficient and quiet. We are very happy we finally made this change and wish we had done it before now.
Review: Very Easy to Install, Very Sturdy and Attractive - First of all, I'd like to state I am a 5' tall, 129 lb. woman. That said, I expected installing this toilet to be challenging but it was very easy after my husband helped me unbox and carry it into the bathroom. I did the rest. I especially like the three bolt system of attaching the tank to the base as it makes the toilet extra strong and secure without any rocking. The height is perfect. You might think this toilet might be too tall but again, I'm only 5 ft. tall and it is just right . The only problem I had (and it really wasn't a problem) was this inside of the tank because the chain was too long and it wouldn't flush proplerly. It was an easy fix; all it had to do was move the clip on the chain down by six links and voila! It works great. I'm happy I chose this toilet.

### ⭐⭐⭐⭐⭐ It's great
*by C***. on April 8, 2024*

I'm 6'3" so I needed the extra height. The dual flush is great. Push on the handle quick for half a flush or hold it for 2 seconds for full flush. There's not much water in the bowl and I thought it was a flaw but it's enough for a huge movement to be gone. Best toilet ever for tall people. Read the description, no seat included. But it's still worth the money. Arrived in 3 days with no breakage.
