Product Overview

The TOTO Aquia II Two-Piece Elongated Dual-Max, Dual Flush 1.6 and 0.9 GPF Skirted Toilet is the epitome of modern form and function. The Aquia bowl and tank set includes tank to bowl hardware, a tank to bowl gasket, outlet socket, and toilet bolt caps. The skirted design conceals the trapway, which enhances the elegant look of the toilet and adds an additional level of sophistication. Skirted design toilets also minimize the need to reach behind the bowl to clean the nooks and crannies of the exterior trapway. The Aquia features TOTO’s Dual-Max dual flush option allowing you to proactively conserve water usage. The chrome center-mounted push button that sits atop the tank allows you to choose between a 0.9 GPF rinse or 1.6 GPF for tougher jobs. The TOTO Aquia meets the standards for EPA WaterSense, and California’s CEC and CALGreen requirements. Additional items needed for installation and use must be purchased separately: wax ring, toilet mounting bolts, water supply lines, and toilet seat.

Hello Georgia, The depth of the toilet from back of the tank to the front is 27-5/8 inches. When installed into a true 12 inch rough-in, there will be about 1/2 inch from the wall to the back of the tank. The overall depth form the wall will be 28-1/8 inches.

I have only had ours for about 8 months and it works fine. I suspect that there is something wrong with the drain flapper. Try flushing and watching the action. If you cant figure it discuss what you observed with Home Depot.

Asked by Sue July 24, 2018

If you'd like to compare colors you can get a set of swatches to see them in person. Please contact our Technical Support team for help in getting these swatches.

what is the difference between aquia II and aquia models

Asked by notaplumber January 8, 2018
4
Answers

according to the toto website comparison tool, the only difference is the seat height. the spec sheet shows 17 3/8" for the Aquia "universal" height and 16 5/8" for the Aquia ii "regular height". also make note if you prefer the one piece or two piece configuration and confirm the rough-in distance you'll need (10" or 12"; the distance from the wall to the toilet drain in the floor).

Is this toilet available in handicapped height?

Asked by sully November 6, 2017
1
Answer

Hello sully, ADA height is between 17 - 19 inches. Aquia model CST412MF has a rim height of 16-1/8 inches. Adding the separately sold seat will provide additional height and can reach the handicapped height, depending on the seat you choose. Aquia model MS654114MF comes with a seat that will be handicapped height of around 17.5 inches. Please understand that the height will be considered handicapped height, but the toilet is not ADA compliant due to the location of the push button being on the center of the tank. Please take this into consideration. I hope this helps and thank you for your interest in TOTO!

This is a good toilet. Flushes well, looks sleek, The only complaint is with installing a bidet. I bought a TOTO bidet, so you think it would fit easy. The problem is reaching underneath to screw the hoses from the bidet into the toilet tank. Had to get a special part made and now the hoses stick out and look clumsy taking away from the sleek look (see photos). It was that, or replacing the whole toilet after it was installed.

Nice toilet! It's a bit different to install then your average toilet for sure. First, it has two mounts that must be attached to the floor first - this may require drilling tile and concrete - at least in my case it was. Do not get the Toto SS204 seat for it (pictured) - it will not stay up. You should get a thinner Toto seat (SS114) .

The Aquia II's sleek lines add elegance to any bathroom. We bought 2 for our remodeled bathroom and powder room and liked it so much that we then ordered 1 more for remodeling the apartment we need to sell. It flushes well (but the installer said it was a bit tricky to install). Other reviewers have noticed (as we do) that the bowl at the bottom is narrow, so you do have to scrub brush the bowl daily to remove unwanted residue. We think it's worth it.

Great toilet
As far as a toilet goes, it looks great! Artistic even. Installed it myself in about 2 hours as it is not a standard installation but not too difficult -- This Old House has a video on installing this exact toilet (search for "install dual flush toilet" on Youtube) that helped a lot. Cleans easily.

Darn good toilet!
This is a great overall toilet. Supreme flushing with a big target area. If your a first time toilet installer, make sure you have a hammer drill with an 11/32" masonry bit if your drilling the anchors into concrete. Everything else was easy to figure out. Took about an hour to methodically install it the right way in this fashion. Overall a great purchase!

The toilet itself is sleek looking however the amount of water that fills the inside is ridiculous. You can't adjust the water level for more water in the bowl. So basically the water line barely covers the hole. It's ridiculous.

Response from TOTO USA AmbassadorJan 14, 2021
Hello Meli, We are sorry to hear that you are unhappy with the Aquia dual flush toilet. Dual flush toilets require a small amount of water in the bowl in order to accomodate the two different flush volumes. We have worked hard to develop dual flush toilets that work as effectively as a single flush, but sometimes they do not work out for everyone. We hope that you will try one of our single flush options in the future. If there is anything we can do to make your experience better, please reach out directly. Our Technical Support team is standing by to take your call. They can be reached at 1-888-295-8134 between 8am - 8pm Mon - Fri EST and press 4 when prompted. We also have live chat on the TOTO USA website. I hope this helps and thank you for choosing TOTO. TOTOUSA

WORST toilet ever
We bought THREE of these during a renovation. They are IMPOSSIBLE to clean. AWAYS stained at the bottom, holes under rim continually clog up, and the design makes it impossible to reach the attachments once it is installed so you can't attach a bidet. HORRIBLE product all round

This toilet is absolute garbage. The bowl is always stained with "#2". I am 44 years old and this is the first and only toilet that I have ever owned or used in my living place that leaves "#2" marks everytime you use it. I would have thought the problem was just me but my best friend has the same exact toilet in his guest bathroom and it has "#2" stains anytime his family uses it. The second major issue is that this toilet constantly leaks and neither toto nor the plumber can figure out why. Either the flap is replaced and doesn't leak for 3-6 months then while the fill valve is also replaced and doesn't leak for 3-6 months. Between the two devices inside the tank, it is constantly leaking. I am spending my saturday replacing this with a Delta Foundations from home depot because it got great ratings on consumer reports.
