Funtional on elongated Kohler toilets, but does NOT "quiet-close"
358786
This toilet seat is functional. It works for my potty training toddler and does fit on my elongated Kohler toilet. However, I chose this seat over the other cheaper options because I thought Kohler would have a high quality product. The adult portion of the seat is not comfortable and has less of an area to actually sit on than my regular Kohler toilet seat. The toilet lid is NOT a quiet close. That is a flat out lie. I would stress the importance of the quiet feature when having an excited toddler learning the ropes of bathroom etiquette. Lastly, someone else complained there was a pubic hair on their "new" seat -- well our seat came with complimentary pee stains.

Perhaps oversized for our bathroom and a bit noisier than expected at 3.0 sones.  Maybe should have decided to install two smaller quieter units at different locations in room (toilet & shower).  Cannot return since I unpacked and put in place.  Will always see it and name Panasonic and be reminded of "error" in using this size and configuration.  Would hope literature explains options better for others in future for larger bathrooms with separate toilet room and shower.

Was able to install between trusses, which are wider spacing than 16" on center joists.  Make certain you can fit.  Otherwise easy install.  Will not use very often due to noise.  Perhaps only when we vacate bathroom and will have to remember to return to turn off.  But will be able to hear it as a reminder anyway.

Installation wasn't too bad, just follow the included instructions.  The unit works as advertised, so far.  However, I have two issues.  One:  I'm not 100% sure the housing for the "Blue Silicone Gasket" will stay in place to keep the toilet from leaking.  The housing unit slides over the overflow tube and is held in place only with a "zip tie" and a rubber ring.  Over time, I'm concerned the housing will move and the blue gasket/stopper will not stay where it should allowing the toilet to leak.  Two: On my toilet which has a front mounted upper left hand corner flushing handle, the flushing button is hidden behind the toilet seat lid when the lid is up, like when you are using the toilet.  When the seat lid is up, you can't access the button to flush because you can't easily get to it.  If the toilet has a flush lever that mounts to the side, then this would not be an issue.
I like the promise of saving water, but I'm concerned with the unit leaking and also don't like where the flush button is located on my toilet.

My toilet has been running for about a month, and the sound was so loud and annoying! Tried to fix it so many times, thought have to buy a new toilet. BUT you know what? After I got this, within 1 minute after changing the old flapper, BRAVO! It stopped running! I I don't even know what model my toilet is, I just know yeah it's two-piece from Kohler, that's how I found this product. So glad that I bought this, no more water wasting and no more sound.

This flapper was easy to install and it stopped the leak. After installation, the flush sounded more abrupt, which caused me concern that the flapper was not allowing enough water through. Turns out the toilet flushes fine. No need for concern.

We recently had a Kohler Archer bathtub installed.  This bathtub doesn't have the kind of drain where you flip a lever; instead, it has a large metal circle that you push down on to fill the tub, and push again to empty the tub.  Because the drain doesn't seal 100% (there is a slow leak), I wanted to find some kind of tub stopper to give us a complete seal.  The problem is, the large metal circle keeps a lot of solutions from working.  In the down (closed) position it doesn't sit flush with the bottom of the tub, it sticks up about a quarter of an inch. One solution would be to unscrew the metal circle every time we want to take a bath, using a conventional rubber stopper to plug the tub shut. But, then we'd have to screw the circle back in for shower use (or leave it out, period)--but that seems like a pain, plus when you've just spent a bunch of money on a new bathtub, you shouldn't have to be inconvenienced like that.

So, I tried the OXO tub stopper, and it works perfectly. I wasn't sure whether it would work because even in the pushed-down position, the metal circle sticks up that quarter of an inch.  I thought it might keep the OXO from sealing properly. Luckily, the OXO is large enough to still seal. While the tub was filling it didn't stay in place, but after I had the tub filled I laid the OXO drain stopper over the metal circle, pressed down on the edges, pressed the suction tab, and it worked perfectly. When I came back about 3 hours later, the water hadn't gone down at all (with just the built-in Kohler stopper, by then the tub would be empty.)

To give you a little more information, my metal drain stopper is 3 inches across and when fully pushed down, sticks up 1/4 inch. The actual drain depression in my tub is 4 inches across. The OXO tub stopper measures about 5 1/4 inches across, and was large enough to maintain the tub seal. So, if it could work with my tub, if you have a bathtub with a smaller drain area I think there's a good chance it would also do the job.

The old one was producing a jackhammer sound that went on for a minute or so. Tried cleaning it out but was unable to resolve the problem. This was easy to install and now normal flushing operations have resumed. I paid a little more for this unit than the standard one, but could not figure out how the roller clamp works so I left that out for now. The directions said to make adjustments using the numbers printed on the part, but there's no lines or marks to line up to the numbers, so I'm not clear at all what those numbers are for, or this part for that matter. Something to do with balancing the water level between the bowl and tank. But regardless, we have a working toilet again and didn't have to pay a plumber.

It is a nice, universal lever, but for some strange reason no matter how well I set it up I have to stand there and hold this thing down for at least 2-3 seconds for it to flush.  If I just push it down and quickly let go it just stops flushing.

Don't buy this if your flange is above the floor at all.  I tried this with mine, which is raised 1/2 inch, and the toilet rocked like crazy.  I couldn't tighten the bolts more without risking cracking the porcelain.  I'm using the Korky version instead.  At least it has adjustments for different flange heights.

This flapper was specified as the correct replacement part for my toilet.  I installed the part myself but was unable to get the toilet to flush properly.  The flapper did not allow water to drain from the tank as it closed too soon.  I hired a plumber to adjust the flapper but he was unable to get the part to work properly.  After an hour he suggested we hold the handle down to allow the tank to drain.  I contacted the manufacturer who verified the part was correct.  Several suggestions were given while on the phone but none resolved the problem.

Easy to install, but does not work perfectly with Toto toilet.

Save your money and get the one-setting version.
This was quick and easy to install, as advertised.  I did also buy the spacers so the toilet seat would still sit level, and the metal T with shut-off valve to control the flow, so that also worked well.

The problem is that in the "feminine" mode, the stream comes out through the (now 1/2") gap in the front!  We have an elongated toilet, so there's no reason it should be aiming that far forward.  I had the stream set low with the extra shut-off valve I bought (not include) and still it squirted right through the front gap and all over the back of my (around-the knee) pants.

You don't need the "feminine" mode anyway, you can just tip your hips and use the regular setting.

TMI, I know, but I can't help it in reviewing a bidet...

I own two of these automatic toilet flush kit and one manufacted by another company that I purchased on Amazon.  The one from Kohler is not strong enough to lift the flapper on my American Standard Champion 4, but the other one is.  With no load, the wheel travels in a complete circle when activated.  Under load, the wheel travels from to bottom to about half-way up and stops.  I tried it with new Duracell batteries with no luck.  Additionally, it does not seem to work every time and you will find yourself waving frantically to get it to activate.  There may be a reset time involved, so I am not sure if this is a real issue, or just something I experienced while testing.  I was not a fan of the (very quiet) beeping noise, but this is just a nit.  For me, it simply did not succeed in its basic function, so I removed it after only a few minutes.  On a positive note, it was really easy to install.

I purchased two of these off of Amazon, as I already had the exact model in a different bathroom. I had a plumber install both and for some reason, the toilet seat is so loose. The screws under the tab are tight and secure, as well as the bolts underneath the seat. It's secure where the base of the seat meets the toilet but it's where the seat meets the hinges. It's only on the toilets purchased from Amazon. Not sure what is happening or if the seats are defective.

I am very pleased with this toilet seat. Until I got it, I did not realize how much I disliked my old regular close style toilet seat. Either I had to carefully lower it each time, or endure the tremendous clatter of it slamming shut.

This toilet seat was easy to install and really is silent as it slowly closes. Five stars.

It's quiet almost too quiet.  May not drown out other noises you may make in the bathroom :-)

This one seems a little bit harder than my previous broken oen. But it functions well. No leaking any more from the tank of toilet. The only issue is it is not easily return to shut the hole until all water in the tank has flushed. It behaves different from the previous one. It's hard to say which one is better. I just level down the valve to save some water. Overall, this product is good.
