Customer Reviews for KOHLER Highline 10 in. Rough-in Complete Solution 2-Piece 1.28 GPF Single Flush Elongated Toilet in White (Seat Included)

I first ordered the Kohler Valiant toilet because of the concealed trap design but when we went to install it... the supply line has to be 8" off center and mine was the standard 4-5 inches so... I had to get a new toilet from what was in stock at my nearest store. This model was available and now that I have it... it is amazing. First, I never thought 1.28 gal flush would be efficient, but it is. And it takes only a few seconds for the tank to refill. I like the lever operator instead of a button and all together is very satisfactory. Plus it was less expensive than the first choice Valiant. I may get one for the hall bath as you get used to the higher seat.

My family and I were tired of being frustrated with a previous toilet that was incompetent at getting rid of solid waste. After comparing several toilets, we decided on this one, and we're so delighted that we chose it. We're only sorry that we didn't get it sooner. In fact, we bought a second one for the powder room, and would buy more if we had more bathrooms in need of a better toilet. I highly recommend this toilet, and am extremely grateful for it.

But this thing is awesome! Amazon Home Services sent a wonderful handyman to remove the old OLD toilet and install this gem. It took him less than 90 minutes and cost less than the toilet and recommended accessories. I can't believe how perfectly and quickly it flushes -- and uses so little water! Wish I had purchased this a long time ago. Would give stars but the toilet seat included is garbage. Latch was broken and seat wasnt usable. Incredibly cheap plastic packed very poorly. Had to go back to the store to purchase a quality seat worthy of this beauty...yes, I love a toilet...

What great quality for the money! We love the look and features of this toilet. Especially the soft close seat and the strong, relatively quiet flush using less water. I will purchase this item again when we remodel our other bathroom.

Im a little ocd when it come to things being out of alignment and it Kohler brand name on the toilet is really upsetting to look at and not be able to hide. Will not be recommending to anyone.

Sleek design and very quiet flushing and filling operation. Easy to install and love the option to small flush for liquids to save on H2O consumption or hold down for large flush. Slow close lid and seat were a bonus for this very economical toilet.

Fantastic toilet - huge upgrade to a really terrible, old toilet. As easy as any other toilet to install. It's quite a large toilet as far as the bowl size - long and wide, which is incredible as a big boy. This is a big boy toilet. Others can use it just fine, and it's amazing - but big boys will appreciate this toilet. Flushes great. Make sure to adjust your chain and water level. I had to adjust my water level to the absolute top to get a good amount of water in the bowl, and moved the chain down 1 link to get rid of slack (just be careful not to overdue either of these adjustments). 10/10. Fantastic design.

I am a women and this is the first time I’ve ever installed a toilet. Completed it in an out an hour including the removal of the old. Directions were great and I found it easy and straight forward. Love the height. The seat. The flush. Everything is great. However! Due to the shape of the bowl where solids hit or collect, every time someone poops it leaves a trace on the bottom of the bowl. I know this is gross to talk about, but it’s bothering me that every time I go to use the toilet there’s poop marks. Otherwise I couldn’t be happier.

Fairly priced, well designed and very easy to install. I love the slow seat and cover.

Plumber had the two toilets installed in 25 minutes. Looks beautiful in my bathroom and I replaced four of my toilets ( 1 round, 3 elongated).

I purchased three of the toilets for our recent home renovation. I was a little concerned at first because the flush didn't seem as powerful as our old toilets. However, these toilets are great. They look good, they are a nice height, they are quiet, they don't seem to use much water and most importantly they move all of the waste out very efficiently. The quiet close seats are also a nice touch. I would highly recommend these toilets.

I’m not sure how this toilet gets such great reviews. To start, when looking at the toilets in the store you are looking up at them. We didn’t think to set up the toilet in the living room to try out or preview. My husband installed it and then we realized how goofy it is. First, the tank is very narrow. But the bowl is so big, it looks like a monster mouth. I didn’t realize the difference in with from the tank to the bowl until I was looking down at it, something I couldn’t do in store. The proportions just aren’t right aesthetically. We joke around it looks like a monster mouth is going to swallow you. I also find the seat quite narrow and almost hurts my legs. We are going to put our old seat back on. But the worst part is that my feet don’t totally touch the ground. I am 5’6” and 120 lbs. I almost fall into the toilet and my 6 year old daughter really does fall through. Other than that it functions well and didn’t seem hard to install. Now I’ve learned to really look at and sit on a toilet before installing. This is something you can’t do in store. Maybe a handicapped, elderly, or very large person would benefit from this but this is not a great toilet for the average size person.

Nice toilet. Highly recommend! Not only is it stylish it takes care of “business”

Looks great and works fantastic.

Toilet sprays water on the lid and seat every flush. There is a hole directly inside the bowl that causes it. Our plumber thought it was a defect in the toilet because he had never seen a toilet like that. I went back to the store to look at the other toilets and they all have it. Im in the middle if trying to exchange it and its been a huge pain in the butt!! Dont buy!

This is an awesome toilet. I was concerned that there would not be enough water and when someone went number 2 it would leave skid marks... Plenty of water, powerful flush, quiet, comfortable and great design...I will continue to buy this one.

Nice toilet for the money. Perfect for a small bathroom. Perfect finish to my bathroom remodel. While the contest says show your product in action, I forego that part!! LOL!!

Installation went quite smoothly except for the part of attaching the tank to the bowl. The flat part of the rubber gasket can not touch both tank and bowl sides to make it more stable. I did not want to tighten screws further since the center part of the water path gasket is already pretty tight. I wish the rubber gasket can be better designed. To prevent possible leak, I add some plumbing silicone grease on the rubber gasket. One thing worth mentioning: this model does have a bit shallower bowl meaning the water line will be closer to the top of the bowl probably by half to one inch. I did not see issues. But other people might. Just keep that in mind.

Easy to install. Haven't had a chance to use it much yet.

Very easy to install and the double flush feature saves water but if you need an extra flush without using a lot of water or waiting for the tank to fill the double flush feature is there. The tank also fills very quickly and quietly.

Ships with undersized washers for attachment to the floor. Fender washers should be included, not the small (tin foil thin) ones shipped. Disappointed with the purchase and will now need to purchase a new wax ring and washers to finish the install.

It’s works great.

Great product by Kohler! Excellent flush system! I would definitely recommend to anyone looking for a great toilet!

We bought three today and my son installed them by noon. They are a more comfortable height, flush fast, and fill fast. My wife says they are quiet and, "all my friends have the comfort height toilets". The acid test will be to see if my grandsons can clog them up.

Easy to install. Nice look and flushes well.

Great toilet. Cutting excess toilet anchor bolts is kind of a pain but other than that it's an easy install. Nice flush action. Looks great. Very happy with it.

The toilet installed quickly in 1 hour and works great....

Warning - Sloppy quality control. I purchased this unit on Jan 14, 2019 and planned on a simple 1-2 hour installation. The floor in my bath was retiled, meaning 1) the surface was very level, and 2) the closet flange was recessed slightly below the surface. Unfortunately the base of the Kohler K11499 toilet was NOT even. The base casting has several support protrusions that extended beyond the plane of the rim. In other words there was no way it could be stable on a flat surface. I spent the next two hours of trying to adjust, shim, and level; finally, I concluded there was no way to stop it from rocking. In desperation, I resorted to a hand grinder to whittle down the supports to a point where the thing would sit flat. Then to top it off, the wax ring provided by Kohler is the thinnest version available. That coupled with the deeply recessed base cavity meant that the ring does not extend past the rim of the base. In other words, it tucks high and dry up inside the casting and never touches the closet flange - totally useless. So that meant another trip back to HD to get a properly sized seal. I should have taken it back to HD, but I was already committed and there was no reason to think the next one would be a better casting. I expected more from Kohler... wrong again!

Sits high and has a powerful flush.
