Rated 1 out of 5 by from Horrible Toilet I have had my Riosa's for 2 years. I bought 4 Riosa's for my house - one for each bathroom. They are horrible, and excrement is stuck on the sides of the bowl after every bowel movement. I came to this website a year ago and saw other reviews had the same problem, and posted a review. They took my review and the other reviews down. Furious as a consumer. (side note - it happens to all 4 toilets for all my 4 kids and spouse - not just me)

Rated 5 out of 5 by from Best toilet I have ever owned We remodeled our main living area so I decided to invest in a new toilet, one with the taller height. As you know if you have shopped for toilets lately, there are a ton of options out there. You can spend anywhere from $89 to a few hundred dollars on a new toilet and after you look at them a while they all kind of blend together. Except for this one. I had never seen the new design for toilets, ones with a smooth side and back. It looks beautiful. It is super easy to clean because there are no nooks and crannies. The handle is on the side of the tank and it feels sturdy. The toilet flushes great and I have only had to flush twice, once. The no-slam lid is a very nice feature. The best part? There are no screws and rubber gaskets needed to attach the tank to the bowl! Delta has the best designed toilets I have ever worked with. There is no chance of the tank leaking because a gasket wears out. Delta has attached a brass fitting on the outside of the tank and that brass fitting is where you attach the bolts to keep the tank on the bowl. It is the best design I have ever seen in a toilet. From now on, if I replace more toilets, I will only be looking at Delta brand. Installing it was almost as easy as installing a regular toilet. I only had to make one trip to the hardware store to invest in an extra tall wax seal because my wood floors were 1/4" above the flange. Once I had the correct wax ring then the install was smooth and easy. If you have ever installed a toilet before you will have no issues installing this one. A truly great product.

Rated 3 out of 5 by from Good toilet, but installation sucks This toilet is good as is, but the plumbing is non-standard. Does not matter unless and you want to install a bidet. Then you find that there is no connector under the tank as in most other toilets, and you have to go running around high and how to find a non-std T connector from the valve in the wall. Would I buy this again? No.

Why did Delta remove my negative review and the other negative reviews on this site? I'm furious as a consumer - and these toilets are horrible. Looks great from the outside, but after every #2, excrement stuck to the insides of the bowl every time!

Asked by: AdamInLosAngeles
Hello AdamInLosAngeles, Thank you for your question regarding your review on the Delta Riosa® Elongated Concealed Trapway Toilet. I am very sorry to hear that your review was removed from our site and I am sincerely sorry to hear that you are not satisfied with your purchase due to the water in the bowl not fully removing waste from the sides and I apologize for the inconvenience this has caused. Since all of our toilets are water efficient models and use less water than a standard toilet, it may help to hold the lever down for a few seconds longer to allow for more water to enter into the bowl from the tank to prevent from waste being left behind. I hope this information is helpful and I wish that there was more that we could recommend in regards to keeping the bowl cleaner. If there is anything further we may be able to assist you with, please do not hesitate to give us a call at 855-345-1345 and we will do our best to help you where we can. Thank you, Brandy Delta Faucet Company Customer Service

Is the toilet cover for Riosa slow-closing?

I could not determine if the seat cover lowers slowly by itself. The Home Depot employee did not know, either.
Asked by: Peter
Yes, this is a slow-closing toilet lid.

water supply line relative to mounting bolts

My water supply line comes up from the floor. For installation purposes, how far to the side of the mounting bolt does the supply line need to be? If the supply line is not far enough to the side, how far back from the mounting bolt does it need to be to clear the back of the unit?
Asked by: CountryDude
Hi CountryDude, Thank you for your question about the Riosa Elongated Concealed Trapway Toilet. As the specs sheet states, it is recommended to be 8 inches from the center line of the trapway. Including at link to the specs sheet. Thanks, Nick http://www.deltafaucet.com/customersupport/documentation/c43906-wh-rsl.html?document=ts&fromDetailArea=bath&documentIndex=0#flashWrapper

Tank Sounds like it is Refilling

Rough-in measurements

I have a toilet that is 11.5 inches from the wall to the center of the bolts. Will this toilet with a 12-inch rough-in measurement work in this space?
Asked by: db
Hi David, Thank you for your question. This toilet should fit your 11-1/2" rough. The other possible rough in sizes are 10" or 14" which will not fit your measurement. Thanks, Dave
