Customer Questions & Answers

How do you secure the toilet to the floor?

Is there a video on securing the toilet to the floor since the bolts are hidden when the toilet is placed?
Asked by: ace
Just installed this toilet a week ago. It does not secure well to the floor. Not good for 100 year old tongue and groove floors. Unlike traditional toilets you can't just tighten it to the floor.

Where do I go to buy a replacement seat for this model?

We installed this toilet in our guest bath last year. It's a great toilet, and we've been happy with it. The toilet seat seems to be wearing faster than expected, and I'd like to have a "spare" in case this one cracks or breaks. What part do I order?

How to install a bidet on this toilet?

I bought a Swash 300 ( in Home Depot. But I found the size & shape of the pipe connecting to toilet tank does match the diamension of the T-valve that comes with bidet which matchs most normal toilet. It takes me several hours to search online to find out an alternative T-valve but can not. What do you suggest to solve this headache? Thanks.

Any bidet seat designed for an elongated toilet will work. We installed one on ours.

Riosa 2-piece 1.28 GPF Elongated Toilet in White is rated 4.1 out of 5 by 178.

It works well, but the seat is very cheap and flimsy and cannot be replaced with standard toilet seats. If you are not a small person, you will break seats on this toilet often, my guess is monthly. Being that you have to buy a special seat from Delta that costs a minimum of $45, this will get expensive after a while. They look great. We have them in our new bathrooms with all new Delta plumbing fixtures throughout, but we are returning these and going with another brand for toilets. Delta should disclose that this is not a standard toilet seat and must be replaced with their own proprietary toilet seat that is overpriced and under-built.

You would not think that a toilet should make me this happy, but Delta Riosa toilet has! I choose this for the simple design and like the slim profile it has. My toilet is in a water closet, so removing the old bulky toilet and replacing it with this slim high toilet makes a huge difference. I did have to use two wax rings to make the connection fix securely, but that is because idiots built the house I live in and had nothing to do with the toilet itself. The flush is powerful with the 1.28 gallons of water. I would recommend this for those who like the sleek design and HATE cleaning around the trap of the toilet. Very happy:-)

After reading hundreds of reviews on various toilets, I wasn't exactly sure if this toilet would work for me. As soon as we opened the box, my husband was impressed with all the accessories that came with the toilet to help remove the old toilet. It was a pleasant surprise. I am extremely happy with the skirt around the base as it makes cleaning around the toilet so much easier. As far as flushing is concerned, it is as described - a powerful flush. Based on reviewed, I didn't install the toilet seat that came with the toilet - I simply installed a soft closing seat that was recommended by other Home Depot customers.

Rated 5 out of 5 by from Modern update. I got this Riosa 2-piece 1.28 GPF Elongated Toilet in White to eliminate some of the problems my wife was having using the bathroom after her stroke. I really like the modern look and the chair height, which makes it easier to sit, without the need for a seat lift. Installation was easy, simply followed the install steps. It came with a removal kit for the removal of the old toilet, very handy! It comes with a slow closure seat, which eliminates the occasional bang of a slipped seat.

Rated 1 out of 5 by from Disjointed in Delta Toilet hard to install.Had my bathroom re-done in November/December. First month all was good. Then toilet started to clog. It was very hard to unclog because plunger did nit fit into the opening securely. Bought 3 different plungers. Last week it started to leak from the bottom. I turned off the water and called the plumber. He told me that the toilet could not seal properly due to side mounting feature. He installed a different toilet because we did not want to have to constantly deal with the constant problems.

Rated 5 out of 5 by from Looks good, works well. I bought this toilet for its sleek looks. I am sure it will be much easier to clean and mop the floor around the bottom, than my old style toilet. I am not sure why a few people had trouble installing this toilet. I read the directions a few times to really familiarize myself with the different install concept. It took me about an hour for the complete install. It is solidly affixed to the bathroom floor, with no movement at all. The three bolts that hold the reservoir tank to the seat are not easy to install, but certainly not impossible. I threaded and tightened all three in about 10 minutes. The low GPF works really well. So far, every flush has been perfect. I highly recommend.

However, I used my own wrench to tighten the supply line to the water supply valve. I was more comfortable using adjustable wrench because it worked better than the plastic wrench. The instructions were simple and accurate and followed a logical procedure. The method used to secure the toilet base to the floor is neat and easy. I especially like the soft close toilet seat. The water level adjustment is simple to adjust.

Rated 5 out of 5 by from Awesome Toilet!!!! This toilet makes whatever you put into it disappear with very little water! I have issues with some of these reviews-follow directions use some common sense and installation is simple and trouble-free. My 300 lb behind can't get this thing to rock so I am guessing those that have issues didn't install it correctly. If there was one gripe it would be that you don't just hit the flush and run you need to hold the handle for a second
