The black finish and skirted base create a clean, simple appearance while also making the exterior easier to wipe down and maintain.

The black toilet uses a rimless swirl flushing system that rinses the bowl evenly and supports efficient waste removal. Dual flush options of 1.0 and 1.28 gallons per flush allow you to manage water use based on your needs. An 18-inch seating height helps reduce the effort needed when sitting down or standing up, offering added support for daily use. The included soft-close seat lowers gently to minimize noise and avoid sudden impact. Designed for long-term household use, this model is backed by a 2-year limited warranty to provide added confidence in performance.

We needed a compact toilet for a small half-bath we built in our detached workshop and this unit was perfect. It’s the second one-piece toilet we’ve installed and although they are pretty heavy, weighing in at about a hundred pounds, they are really easy and quick to install. Our installation was on vinyl laminate planks installed over concrete and it went right in. The unit mounts with no visible closet bolts, as they mount internally. The supplied closet bolts were easily tightened using a socket wrench with a 7/16″ deep well socket. Access is via a small hole in either side that gets covered with a matching plastic cover. It looks very modern and slick when completed. One of the closet bolts spun in the flange, however, we got tighter, so we had to switch to a ratcheting box wrench so we could hold the bolt with small vise grips. The supplied wax ring was a nice reinforced one, which we prefer. We did find that we absolutely had to tighten the closet bolts to get the unit to sit flat on the floor, but after tightening, it was rock solid, with no wobbling. We actually built the room with a 12 in. rough-in, but this unit does not look out of place even though it is designed for a 10 in rough-in. We had no access issues behind the toilet, but if this was against a wall with the 10 in rough-in, attaching the supply line would be tough. It’s a good idea to attach it before bolting the unit to the floor, to make it easier. Performance is paramount for a toilet and this unit works great. The siphoning action is strong and flush is thorough with both of the two flush settings. The unit is tall at 18″ which makes it easy to use. All in all, we’re very happy with this unit. It looks great and performs just as well. Definitely can recommend this unit.

I am remodeling an older home and pretty much nothing built in it is “standard” and so of course that had to extend to my half bath as well. The rough in is 11” – not 12” or 10” which are standard, so I had to find this out the hard way after trying to install a 12” rough in toilet first. Needless to say, that didn’t fit. So it took me awhile to find a good replacement but I’m so glad I took the time to research it correctly. I got this toilet in black, and I’m so glad I did, it looks stunning! And it fit! The one-piece design was perfect for my tiny bathroom as it takes up a much smaller footprint. I really needed the foot room. Oh, and the soft close lid is also a nice feature. Installation was straight forward this time with no issue, the clever design actually made installation much easier than I’d expected. Overall, I feel like I really pampered myself with this purchase!

Can’t speak to long term gloss but the beautiful finish on this toilet is AMAZING!! This is a high profile sleek toilet easy to clean and TURBO charged on a very small per gallon water usage!! Flushes masterfully and gets the job done!! Item arrived packaged PERFECTLY… no worries on breakage all necessary parts were included … other than a supply line from cut off valve. Instructions are straightforward. There is a toilet valve adapter connection on the toilet you may need to remove prior to install and would recommend connecting flexible toilet tube connect prior to install. The surround of the toilet is seamless and will make cleaning so much easier as walls of toilet cover those aggravating bolt covers that collect dust. It was tricky trying to align the flange bolts with the inset holes on a black toilet in confined space … put tape on floor out from bolts as a guide proved helpful. The seat comfort might be an issue for small rear ends… per other comments the rear opening seems wider than other toilets… but overall not an issue! Seems high quality and very pleased with product!!

If you want a stylish looking commode that is easy to install, functions quietly and has quality components and finish. I would consider this fixture. The install is easy once the old toilet is removed. Make sure your flange is level with the floor or add spacers to ensure it is. Then add bolts, wax seal and lift in place. It is heavy but I did it alone. If you have a bad back ask a friend to help. I use plastic straws to guide in place to make it easier to align. Don’t over tighten bolts just firm to floor, so the wax seal mushes in place. Instructions provided are clear and easy to read. If your floor is uneven you may need to shim but normally this is not necessary. I like the look and would certainly consider it again.
This is the most elegant toilet I have ever seen, I love it. The design is flawless. No more getting under the toilet to clean. This is a dual flush, 1.0 for light flush and 1.28 for heavy flush. This will save me alot of money on my water bill. Comes with a quiet closing seat, NO More Banging! It’s 18 in tall which is great for my cervical stenosis and bad knees. The main jet hole is angled sideways shooting out horizontally, creating a powerful swirling whirlpool effect. Rimless swirl shoots water at 360 degree high speed, and uses the kenetic energy of the water to scrub the entire bowl with little water.10in. Rough Ins is for small bathrooms. This has the tank half the size of a regular tank. I highly recommend this toilet.
