The sleek stylish design of this Riosa 2-Piece Elongated Toilet in White provides innovations, maximum performance and water-savings. Beautifully designed for easy installation, maximum flush and water savings, Delta toilets are the smart choice. All Delta toilets feature the exclusive Smart Fit tank-to-bowl connection. This technology eliminates potential leak points and the fear of over-tightening bolts. All while adding stability to the tank and making for an easier installation process. The Riosa features a factory-installed supply line that resided in a channel on the back of the tank above the water line, eliminating another potential leak point. The concealed trap way gives it a smoother, cleaner look. The elongated bowl and chair height allow for greater comfort. The quick-release seat allows for easy cleaning. This stylish design provides maximum performance and water-savings. Another smart innovation is the inclusion of a toilet removal kit. The kit includes items needed to aid in the removal of your existing toilet: a pair of disposal gloves, disposable scraper, highly absorbent sponge, and cloth. No additional tools are required to assemble and install this complete toilet.

Rated 4.4 out of 5 by 46 reviewers.
Rated 5.0 out of 5.0 by High toilet After a major remodeling of the master bath two years ago, it was time to do the guest bath. One of the major changes would be a high seating toilet to accommodate the aging in the! Besides meeting that need, this model is excellent as it will not collect dust on the base as those other toilets with the coil-like base showing. The smooth straight lines of the base will make my life easier as I won't have to bend and clean the collect of dust on those coils! It is the little things that makes my life happy! I do have to tighten the seat a couple of times a week. February 11, 2014
Rated 4.0 out of 5.0 by good enough pretty basic toilet, with the exception of the way it mounts. I really like the clean look with the way this toilet mounts to the floor using the side mount bolts instead of the floor mount bolts. Looks cleaner and more high end. February 28, 2015
Rated 4.0 out of 5.0 by What you need to know Very good flush. Modern but the tank lid befits a more traditional theme for wider appeal - if they offered a simple, thinner, plain tank top, with out crown-like edge, and a more spartan modern flush handle the toilet could compete with far more expensive brands/models. I knocked out a replacement tank top out of white Corian counter top material, polished it up (it’s only ¾” thick) and took a flush handle from our old Kohler Rochelle and man it looks like a very high end toilet. Parts. Delta has gone out of their way to make sure that absolutely no aftermarket internal tank parts can be substituted. All proprietary parts, locking you into their pricing for future repairs. Flex line comes attached and is also proprietary. It has a ⅜” compression termination so you will need a shut off that has ⅜ outlet. Seat. For this price you get a good seat included. Self / soft closing seat - both seat & lid. Cassette type quick release for easier cleaning. The release mechanism / part that bolts to toilet does not look durable. Mounting. Delta has this ‘wack’ mounting system - it’s two thick plastic ‘L’ brackets you bolt to the floor flange and then use two thin sheet metal screws, through side of bowl, to secure. This makes it necessary to lay out a good bead of silicone to bottom of bowl before it is set into place to avoid future movement. Set bowl into place on floor first - without wax or silicone - mark sides with tape close to edge of bowl - then remove, set wax (included but I buy another to use to smear flange and bottom of toilet flange first before setting wax ring), and then lay a thick bead of silicone onto clean floor where bottom edges of bowl will rest (the extra squeeze out will overlap onto tape. You can then wipe away the silicone (clear) removing it all deep from the crevice as this is just to seal bowl to floor & grip not for a finished bead. Use a terry towel to get all the clear silicon out. Later you can run an exterior bead of white silicone if you desire. If you cleaned out all the silicone and used mineral spirits to get it clean (off of floor and ceramic bowl sides you won’t have any issues with getting white finish bead to stick). The floor flange must be above floor line by about a ¼” for a proper wax seal - set toilet 'dry' to make sure you have the clearance plus a 1/16" for the wax they supply (was has internal black plastic reinforcer at least a 1/16" thick). If you have an old cast iron flange the plastic ‘L’ brackets will need to have the ‘teats’ on the bottom belt sanded off. The ‘teats’ lock into a more modern flanges slots. With cast iron there are not slots so you will get a better bolting if you cut off or sand off the teats. When you set the bowl and then later go to insert the two supplied sheet metal screw into plastic ‘L’ brackets it might be hard to tell when you have tightened them / threaded them in enough (to just make the plastic brackets snug against inside wall of toilet) - so a trick is to place a small mirror & flashlight behind and you can now see exactly what you are doing. *(for the final bead of white silicone exterior bead search Youtube for using aerosol glass cleaner to make a finish like the pros - you'll dig it. Silicone in a bathroom lasts & wears far better than modern water clean up 'loser' sealants. If your installer is afraid to use silicone you now know they are not professional and you can get someone else. You are paying for a pro they need to be pro). Don’t hire a standard shmoe plumber to put this toilet in either, you will want someone with a brain. Once in, you WILL like the toilet and be pleased with the purchase. I like TOTO toilets but this flush is every bit a good if not better. The price for what you get puts this into the bang for the buck category. People complaining about the difficulty of the seat installation just don't understand that what they are giving you is essentially two 'toggle' bolts. You have to take them apart first, firmly but carefully/gently tap in the plastic expansion toggles USING SOMETHING OTHER THAN METAL to seat them all the way in to avoid chipping. Then place seat 'cassette' over - then place square washers and bolts through. Don't use supplied Phillips screw driver for tightening - use a dedicated Phillips hand held screw driver. You will need to really tighten these down to secure. October 24, 2014
Rated 5.0 out of 5.0 by Best toilet yet We wanted a toilet with a higher height, had above average flushing ratings, and didn't show the harder-to-clean nooks and crannies on the rear of the base. Since we're plumbing challenged, we used Home Depot's installation service which worked out quite well (the San Antonio contractor was one of the larger and well-rated plumbing firms here). The toilet exceeds our expectations. After almost a month of use, it has performed flawlessly. The slow-close seat was an added bonus. No drips, no clogs, and quite quick and quiet - its performance confirms its top 1,000 MaP flushing rating. We'll be purchasing a second one for our guest bathroom later this week. Absolutely no buyer regrets! February 26, 2014
Rated 5.0 out of 5.0 by would do it again Replaced original built toilet in guest bathroom, looked at all makes and models, this clean hidden side was very appealing. looking at the price made me hesitate. But, knowing Delta and looking at advantages we went for this model. This product has all the stuff to help you do it, even a wrench and fitted screw driver, the soak up cloth and sponge too! took two hours, I just had a knee replaced so I was a little slow. This was fantastic, it looks good, the seat wont bang down. very innovative. going to do the other three soon, its worth it. And its quiet and efficient. October 22, 2013
