Kohler 3493-96 Highline Classic Comfort Height two-piece elongated chair height 1.6 gpf toilet, Biscuit

I wanted a toilet that would not clog unless I was putting something in there that most definitely should NOT be in there, and on that, this toilet delivers. It's extremely powerful and you can say goodbye to clogs.Performance wise, you have a commercial grade commode that gets rid of your waste with authority. The toilet is designed with efficiency in mind to go along with the pressure, having the biggest trapway I've seen. There are absolutely minimal obstructions for any waste/paper to cling on to. Like I said before, unless you're putting something in that most certainly should not go in there, you should never get a clog. Of course, there might be a problem with the plumbing down the drain line but it's EXTREMELY unlikely the Kohler will be at fault.It looks very nice too, like a premium toilet should (excluding those crazy $1000+ Japanese ultra-fancy models I can't comment on those).As for the packaging, it came in two absolutely huge boxes. These boxes had enough oh-so-environmentally friendly styrofoam packing that it nearly filled my (previously empty) garbage dumpster. I suppose that's the price you pay though, for making sure the fragile porcelain doesn't arrive cracked.I can't comment on ease of installation, as I had my plumber do it. I will say though he had no issues that I could see; it went without a hitch.This toilet is LOUD. Not as loud as the earlier pressure models, but I don't know if I'd want this installed in the master bathroom, unless your SO doesn't mind hearing a loud whoosh when he/she's trying to sleep. YMMV.Only slight problem I had was with the flush bar. It kept coming loose. I adjusted the flush actuator up a bit because I felt it had a bit too much clearance from the bar, it hasn't come loose again after that but I'm keeping an eye on it.Overall I highly recommend this toilet if you are sick and tired of clogs and you want to buy a toilet you can be absolutely SURE won't clog again!

I rarely write reviews, but perhaps I can help some other individuals who have purchased the Kohler K-3493, and experienced flush lever problems. I own two of these toilets. The first K-3493 I purchased the flush lever and actuator linkage worked perfectly. I decided to purchase another K-3493 to replace another toilet in my home. When the second K-3493 arrived, the flush lever (aka trip lever) and the actuator linkage were essentially not connected. It was impossible to link the two so that the flush handle would link up with the actuator lever to flush the toilet. Close inspection of the toilet revealed the cause. The Flushmate tank was rotated to the right in the toilet bowl. When viewing the tank from the front, the left-hand side of the Flushmate tank was higher than the left, with an apparent clockwise rotation of the Flushmate tank to the right. This rotation displaced the Flushmate actuator arm away from the lever handle arm causing the lever problem.The toilet tank was disconnected from the toilet base and the outflow gasket was removed. This revealed that the 3 inch nut on the outflow pipe of the Flushmate tank had been cross threaded! Please refer to the attached photo. This nut had been torqued down at the Kohler factory with such force to effectively rotate the Flushmate tank in a clockwise direction. Please note that these are plastic threads which should only be hand tightened. The 3 inch nut had been torqued down with such force that I had to use a large set of channel locks in conjunction with extreme force to loosen the nut. During this process loud audible screeches were heard emanating from the threads on the outlet of the Flushmate tank.I cannot understand how this toilet tank was allowed to leave the Kohler factory with the linkage which would not flush properly, and a toilet tank that was improperly positioned. I contacted Flushmate Customer Service, who promptly shipped out a replacement Flushmate tank. Kudos to Flushmate who deserve a five star rating, and provide great customer service. I received the replacement tank, which was easily installed in the toilet bowl. I hand tightened the threads on the 3 inch nut and just slightly applied the channel locks to complete the job. Again it is beyond reason why anyone at Kohler would torque down the Flushmate tank with such force. Once the replacement tank was installed the OEM actuator linkage coupled to the lever handle arm perfectly. Thus the lever handle problems are a manifestation of an improperly positioned tank rather than a defect in the design of the actuator linkage.The new toilet has now been installed and appears to be working properly. You would think that Kohler Customer Service might have offered to ship out a new toilet tank given the fact that the unit was new, defective, and cost me $474. But no, the women in their Customer Service department apparently expect their customers to replace the innards of their new toilet tanks, which are defective right out of the factory! In terms of function the Kohler K-3493 should receive a five star rating, but the lack of quality control at the Kohler factory coupled by the apparent indifference of their Customer Service department gives them a one star rating at best.

Absolutely love how this looks, great quality. Very loud flush but we had been having issues for several years with our old toilet clogging up. After several months of use since replacing both bathrooms with this toilet, we have never had one clog issue. Just warn your visitors before they use your bathroom of the colossal flush! Ha
