Rated 4.5 out of 5 by 145 reviewers.
Rated 5.0 out of 5.0 by Love this toilet Got this toilet for our new bathroom remodel. It really works well. Everything goes down with hardly any water. Our old toilet would get blocked weekly - now that's a thing of the past. Highly recommended. February 18, 2014
Rated 3.0 out of 5.0 by Needs better quality control I bought this toilet for two reasons: a) it matches the other toilets in the house and b) the water use was less than the toilet it replaced. What I didn't expect was that the holes for the toilet seat were not put in correctly so that the toilet seat sits cockyed on the toilet. I measured the holes and, sure enough, the holes were put in crooked. I compensated by bending the hinge on the toilet seat, but I shouldn't have had to do that. Otherwise, the toilet seems to work as intended. November 8, 2012
Rated 5.0 out of 5.0 by A bargain This product was well worth the money. The toilet, once flushed, has more water than the average in the bowl, mainly due to the shape of the bowl. But I like this since it is easier to clean. The flush is a little noisy, but works extremely well for the type of flush required each time (Short flush or long flush, as well is in between). The appearance of the toilet is good. Except for the weight, it was very easy to install. It is no heavier than any other toilet, but my muscles are not as good as they used to be. My overall review is that the product is very good, the price was great, and I made the right choice. December 17, 2014
Rated 5.0 out of 5.0 by Kohler Toilet It is a beautiful toilet. Love the square top. Really updates the bathroom. May 19, 2015
Rated 5.0 out of 5.0 by Amazing! This toilet is amazing! Every time I flush it, I wonder if it's worked, it's so quick and quiet. But, lo, all clean with just a single, tiny flush. It was very easy to install, though I wish there had been better documentation in the box. Be sure to look for the pdf installation instructions on the Home Depot page where the toilet is listed. It's got the pictures and step-by-steps. The only thing that was kind of a hassle was trimming off the posts that screw it to the floor. I guess this is a standard thing, but I wasn't prepared and had to buy a small metal saw (cheap). You will need two people to lift and set the toilet in place, unless you are very strong. In any case, this is a great value and an easy project for a couple of low-skill DIYers. I can't wait to see if my water bill goes down... October 2, 2014
Rated 5.0 out of 5.0 by kohler toilet what can I say about a toilet. a plummer put it in and the tile got chipped a little and it is old tile so I may never be able to fix it which makes me sad. other than that I'm happy to have a good working toilet and the sales man was very very helpful.

Rated 5.0 out of 5.0 by Great toilet for the price This is my second Wellworth Classic toilet. It was installed by a Home Depot recommended plumber and the installation went nicely. The toilet was shipped to me and arrived securely wrapped with lots of insulated packaging. Toilet flushes well and is a great buy for the money. I would definitely recommend this product.

Rated 1.0 out of 5.0 by Terrible - Lasted Two Days If I could rate this a ZERO I would. My six-year-old clogged the toilet within a couple of days of use. No plungers work on this toilet. Turns out, neither does a toilet auger. Also, it's very hard to clean because of the ridiculous design. This toilet looks nice. Buy it for a flower planter if you're so inclined. It might have enough drainage for that. If you want a toilet, this one is a piece of you know what. I have 14 properties, and this is by far the most disappointing fixture that I've ever replaced.
