The Persuade Collection captures the essence of modernity in subtle curves and clean lines. With its sleek symmetry, this two-piece Persuade Curv toilet adds style to the bathroom without sacrificing water savings. The toilet flushes with the press of a button, offering the choice of 1.0 or 1.6 GPF. The high-efficiency 1.0 Gal. flush setting reduces water use by more than 30% over the 1.6 Gal. mode, which adds up to potential water savings of more than 5,000 Gal. per toilet, per year.

Rated 4.0 out of 5 by 32 reviewers.
Rated 3.0 out of 5.0 by Just remember valves wear out! I purchased this toilet and installed it today. I am currently happy. I Give it a 3 star simply because the toilet doesn't use the standard fluid master flush valve which costs about $12 to replace. In the event the flush valve on this toilet wears out in 3 -5 years (like they do) one can either pay the $200 part replacement price for a new flush valve specific to this toilet or replace the toilet. I love Kohler products and have nothing negative to say about the toilet. I just wish they would either inform the customer of the expense down the road or stick with a standard valve that is inexpensive to replace. April 13, 2012
Rated 4.0 out of 5.0 by Persuade High Efficiency Toilet I had my contractor install this toilet, and he said that the manufacturer included all parts and good instructions, but installation took much longer than a standard toilet, and that any future repairs are difficult to resolve due to its design as well as any parts for this toilet will have to be special ordered. I love the sleek design anyway, and the ease of cleaning the base. The comfort height makes it easier to get up and overall, I am very happy with it. March 10, 2015
Rated 4.0 out of 5.0 by Love the look We installed two of these in our house six months back. We still love the look and we received compliments from guest who stayed with us. They were a little tricky to install. If the back wall is not straight, you will see a gap between the wall and the toilet itself. The super water saving flush doesn't always get rid of all the liquid waste so a second flush is often required. Kind of defeat the whole purpose. Given the shape of the bowl (somewhat vertical with just a little bit of standing water on the bottom), you will want to have a brush nearby. January 2, 2013
Rated 1.0 out of 5.0 by Persuade flush valve - flawed The flush valve mechanism is flawed. I've been through a couple replacements of the innards already to no avail. There's a steady internal leak. The parts are hard to find, and I've now found reviews saying that plumbers avoid installing this thing -- it's complicated and doesn't let you get to the back of the unit for repairs. I would not buy another kohler. the Gerber 1.6 gallon is actually more efficient because it doesn't leak and has a reliable flush. October 6, 2013
Rated 2.0 out of 5.0 by Disappointed The look of the toilet is great, however, its functionality is sub-par. We've installed 2 of these three months ago. Both usually require 2+ flushes to remove all waste (including toilet paper). Since the bowl holds very little water, we often find ourselves (not meaning to sound gross) having to physically wipe solid waste off the insides of the bowl with toilet paper due to the lack of standing water. The price paid for these commodes was not worth it. No quality here. May 31, 2015
Rated 4.0 out of 5.0 by Post installation hind sight I bought this toilet mostly because of the efficiency, but also because of it's style and height. First I found out that it wasn't the easiest to install. Picking up 120 lbs and placing it over the receiver was more than I thought I could do. Luckily I had room to assemble the tank AFTER I had set the stool. Otherwise, I don't see how one guy could do it. The template provided was great. The dual flush was the seller for me, because our utility company priced sewer change and trash by water volume. The 1.8 and 1 gal flushes seemed ok although others were 1.8 and .8 gal. Now that I'm using the toilet the 1 gal. flush isn't even quite enough sometime, but what you save otherwise makes up for the "extra" flush when necessary. There is one annoying nuance to the toilet. Since the back of the toilet is open, when you go #1 the dripping echos through the rear. I've never sat on a stool that did this, but I've never sat on one that was "open" at the rear. I'm working on some type of cover to muffle the sound, but may just get use to it. May 2, 2011
Rated 5.0 out of 5.0 by Perfect For a Small Bathroom The narrow width of the tank makes our small room look wider. The two volume flush works fine although I can't tell the difference between 1.2 and 1.0 L flushes. One complaint: Kohler needs better quality assurance. The tank comes pre-assembled with the flush and Fluidmaster filler. I spent two days chasing a leak from the tank. I couldn't believe until I exhausted every other possibility that they would forget to use the rubber gasket between the Fluidmaster and the tank. September 6, 2011
Rated 2.0 out of 5.0 by Skip this model. Very disappointed. Materials were cheap. Installation process requires making template for the floor. The dual flush buttons were so small that only a childs fingers could fit on them to use them. We returned it for a different brand. April 24, 2012
