In regards to the Memior Classic toilet, what is the difference between the K-3816-U-O and K-3816-O?

Asked by Johnboy July 13, 2015

Hello, my name is Justine with KOHLER Customer Service. I am happy to assist you with your toilet question. The difference in the two memoirs model toilets is that model 3816-U-0 has an insulated tank that minimizes condensation on the tank when exposed to high humidity and the 3816-0 Does not. For additional assistance on this inquiry, please contact our Customer Care Center at 1-800-4KOHLER. (1-800-456-4537) Thank you for your inquiry and choosing the Bold Look of KOHLER.

What is the flush rating of this toilet and can it include a seat that does not slam down?

Asked by Ibisman April 11, 2013

Thank you for your inquiry. Technology Single-flush gravity uses the force of gravity and a precision-engineered tank, bowl, and trapway to create a strong siphon during flushing. Canister flush valve optimizes flush performance and resists warping and deterioration. Class Five® flushing technology offers plug- and leak-free performance, extraordinary flushing, and better rinsing power for a cleaner bowl. The MaP flush score is > = 1,000 The 4636-0 (Grip-Tight Cachet® Q3) is what is recommended for the 3816-u-0 toilet.

The entire ordering ordeal was awful. The first order, the toilet arrived cracked. The second order, they lost the toilet in the store. The third order, the toilet is missing the toilet seat. I’m very disappointed.

Response from Kohler Product ExpertFeb 7, 2018
MichaelGuidry, my name is Jessica with Kohler Customer Service. I am very sorry to hear that your first order was received damaged. I do apologize, K-3816-0 does not come with a toilet seat, any of our elongated toilet seats are compatible. The following link is to our current options: If you have any further questions or need additional assistance, please contact our Customer Service team at We're happy to help! - Jessica P.

The tank and bowl must have been made at different times. Although both were listed as white on the order form and the box in which they were delivered, the tank appears to be a darker white. Also, the inside of the bowl is slightly misshaped which is noticeable when filled with water. Quality control is obviously lacking.

a purchase Ive been waiting for FOREVER
Ive notice this style of toilet for many years. My best frined has sink, toilet, and tub in her bathroom. I finally purchased a older home, 1950, brick, rambler style. I kept all the original tile, just changed out sink, toilet, lighting and mirror. Looks amazing. Only one problem, when I opened the box the toilet has a scratch directly in the middle of the tank. My contracter called that day and said, " hey i have time today, want it installed"? I called H.D. and i was offered a 80$ gift card. Thank you. However the $ went back to you guys and Im still looking at a scratch. Michael Elizzar
