This Works Great in our New Bathroom
I bought this to add to a new bathroom we installed in our house. Contrary to other reviews, I did not have any problems with the shipping. Both parts arrived together. This has all the parts I needed for the installation except for the hose to connect it to the water supply. ( I think it's standard that you always have to purchase that separately). This looks nice in our bathroom and flushes great. It is easy to clean, is comfortable, and does not have any leaks. ... show more

Great toilet
Size: Standard Height Style: Modern Pattern Name: Tank + Bowl
I thought this from Amazon because I was lazy and didn’t want to go to the home improvement store and lug a toilet back home. So that was cool to get this delivered to my front door. It does not come with a toilet seat which is super weird in my book. Good thing I just bought a slow close seat for the toilet I was replacing. Install is pretty straight forward. It’s a little more difficult than other toilets I’ve installed. The flush is powerful, yet quiet. Quality of material seems to be really good. It’s comfortable to sit on. It’s a slim toilet, the back tank looks too small, but provides the right amount of water, so I guess the design is good. ... show more

Power Flusher
Size: Standard Height Style: Modern Pattern Name: Tank + Bowl
Next to my iPad, this is one of my greatest purchases. No post purchase regrets, with either of these products. The engineering that went into the design is apparent. The tall tank offers great potential energy in the water delivered to the flush ring. The flush ring water enters the bowl through the siphon jet, forcing the trapway (siphon) water over the hump to develop a powerful siphonic action. The siphonic action is amplified because of the 2” trapway. Next to a commercial toilet, this is the most powerful flushing toilet I’ve seen. I installed the toilet with the superior parts that came with it. Installation was simple and straight-forward. I appreciated the stainless steel tank bolts, Fluidmaster Fill Valve and Fluidmaster Flush Valve. These are time-tested and inexpensive replacement parts that work well. I used a simple wax seal to mount the toilet on a flange that was level with the tile floor. ... show more

Only got half a toilet. Expensive, useless junk.
Size: Standard Height Style: Modern Pattern Name: Tank + Bowl
I'm in the middle of fixing up my house. I bought this toilet last year, it came in a big box, and since I needed to tear out the rotten bathroom floor before installing the toilet, I set it to the side and didn't open the box until today. To my surprise, the big box was nearly empty, containing only a tiny box with the toilet tank inside, but no toilet bowl. I'm very angry. It was a lot of money to pay to receive only half a toilet, and I can't even buy the bowl anywhere, because they don't appear to sell it. I see that several other reviewers also got only one half, either the toilet tank or the bowl. If you buy, don't tell yourself they wont do the same to you, because they will. ... show more

Excellent Toilet - Totally Underrated
Size: Standard Height Style: Modern Pattern Name: Tank + Bowl
I manage a small apartment building. This toilet is great because of: 1. 1.1 GPF 2. Standard, simple flush mechanisms -- replacement parts can be found everywhere. 3. Low cost. 4. Good brand -- Am Std. My go-to toilet has been the American Standard Cadet 3 -- the 3 represents the 3 inch trapway between the tank and bowl. The Cadet 3 1.6 gpf was amazing and never ever clogged. The Cadet 3 1.28 gpf wasn't bad, but in reality is was really the 1.6 with less water in the tank. The problem was that a lot of water velocity was lost. This 1.1 gpf works great. It had to use a few a few tricks/tweaks vs the Cadet 3: 1. The trapway is back to 2". 2. The tank is narrower, forcing water in the tank to start at a higher level (potential energy state). 3. The tank's flapper closes quickly, but you can hold it down for flushing "bigger loads". 4. The bowl's waterway is a little more constricted so that it requires less water. 5. You can see the other design features on the American Standard website. Overall these tweaks create great water pressure/flow/suction. It's really quite impressive. If you need a more water, just hold down the flush handle a few extra seconds -- no big deal. Tips for you installers: 1. Don't use the included Fluidmaster fill valve. Buy a Korky Platinum. It's much better. 2. Buy your own seat. 3. Buy the Fluidmaster Better Than Wax seal. 4. Don't forget to use shims to make sure the toilet is secure. I say this toilet is underrated because it is a special-order item at Home Depot. If people saw it in the store, I think it would ruin the sales of the other more expensive toilets. I am wary of fancy dual-flush toilet mechanisms. One single plumber phone call can ruin all the money saved by using less water. KISS - Keep It Simple Stupid is my motto. ... show more

Item was damaged during shipping
Size: Standard Height Style: Modern Pattern Name: Tank + Bowl
Have ordered several. Great product by a great company. However one was broken upon arrival. Had to load and take to the USPS for return and was not given a QR code to return. Had to print out label at home. Very heavy to lift on the counter scale not sure why Amazon decided to make the return so difficult. Should have used UPS for return the counter scale is not so high and designed for heavier boxes. Horrible experience for returning this damaged item. ... show more
