TOTO CST453CEFG#01 Bathroom-Hardware, 1.28Gpf/4.8Lpf, Cotton

Just like everyone else says,, it's a wonderful toilet. We bought the Toto toilet seat/lid and it is nice too.Update:I just finished installing my second CST454CUFG#1 Drake II. They are the best flushing toilets I have ever seen, even comparing them to the old high gallons per flush toilets of 5 decades ago. I replaced water saver toilets of the 90s, which were marginally ok. I see where another major brand is using the same flush system too. Toto gets my highest ratings.Getting the unit to my home unbroken was somewhat of a problem. The first tank was delivered by FedX and it was fine. Next day, UPS delivered the bowl and it was badly broken. No problem, Amazon had me another on the way the next morning, and had UPS come get the broken one. Then another tank arrived, but I wasn't home to refuse it, but UPS came to pick it up the next day. The following day, UPS brings me the second bowl, and the delivery guy tilted the box and we heard pieces tinkling. He opened it and it was also broken so I refused delivery. Spoke with Amazon about getting a bowl instead of a tank and bowl. They said they were ordering another and just refuse what I didn't need. The day after that, 2 tanks and 2 bowls arrived on the UPS truck. The first bowl we checked was good, so I refused the other 3 boxes. They probably need to sell the bowl and tank separately and just make sure when you order the bowl, you need part number #### for a complete fixture. But I am a happy camper and Amazon performed flawlessly.

1.5 months of use as main toilet in the house, and we are going to replace our secondary toilet with another of these when we redo the bathroom.Single flush is 1 Gallon but we have yet to need >1 flush, which is exactly what I hoped for. 1 Gallon flush means that this is better than a dual flush model and is in my opinion less likely to break. Flush is very quiet, startlingly so after our previous toilet.Bowl has remained clean much longer than our other toilet, and the toilet overall is very attractive. It does have more of a 1 piece look due to the close coupling, which I think looks great.I did a ton of research before picking this toilet and had to talk our plumber into it, and I'm glad I did. Using 0.6gpf less than our previous toilet (and 2gpf less than the secondary toilet we will replace soon!) is good environmentally and for our water bill as well.Update 3/21: Still working great. Never had to flush more than 1x, no issues of any kind so far. Second toilet just went in, replacing an old 2.5gpf toilet.Update 12/2016: Since posting this review I moved and first thing I did was replace existing toilets with two more of these. Perfect performance. And then I moved again :( I hate moving but I love these toilets! What was the first thing I did in my New New house? Replaced 2 more existing toilets with these toilets.So I have purchased and installed 6 of these so far in 3 different houses, and I still think they are awesome and have yet to have a problem with them

Had this toilet for a few weeks and it does flush solids better than my old toilet but is not perfect. When it does clog up it is harder to unclog due to the shape of the opening at the bottom of the bowl. It has a rectangular recess above the opening so a plunger will not seal and when you "plunge" the water sprays out all over you and the toilet. I had to go buy a toilet auger to clear plugs. Definitely not worth the $400 when you include the seat and seal.

OK, we shopped quite a bit before buying this model. Read reviews, watched videos, tried some out, debated the height at length and finally bought this one. We were somewhat hesitant due to it only using 1-GPF but after using it for a month I have to say that we love it. It has always cleared the bowl on the first flush. It refills quickly even though we have low water pressure. My old toilet that used lots of water took about 4 minutes to refill, this takes about 10-15 seconds. it stays clean. It is a comfortable height, I'm 6' 3" and my wife is 5' 6". I estimate that the payback period based on water savings will be slightly over 4 years. Even without a good ROI I would still buy this. Nothing worse than having to wait for the old toilet to refill so you can cross your fingers and hope the second flush does the trick, especially if you are a guest.Installation was pretty easy; The folks that said it wasn't didn't say why. It's not fun cleaning out the old wax ring but I would rate that as tedious not challenging. I would not recommend the Fernco coupling to install this unless you have fairly new construction. I ordered one and bought the wrong size (I needed the 4"). I then picked up a 4" fernco from a local big box store and it didn't work for me. My cast iron pipes are really old and I think rust build up on the inside interfered with the coupling fully seating. I had to pull it up and go with wax which was easier in given the fit issue I had.I will order another soon for the second floor bathroom.
