Description

The TOTO Aquia IV Two-Piece Elongated Dual Flush 1.28 and 0.9 GPF Toilet with CEFIONTECT is the epitome of modern form and function. 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 IV features TOTO’s DYNAMAX TORNADO FLUSH, utilizing a 360 degree cleaning power to reach every part of the bowl. This version of the Aquia IV includes CEFIONTECT, a layer of ceramic glaze that minimizes waste from sticking to ceramic surfaces. This feature, coupled with DYNAMAX TORNADO FLUSH, assists to reduce the frequency of toilet cleanings, minimizing the usage of water, harsh chemicals, and time required for cleaning. The enhanced design of the Aquia IV inner bowl reduces water flow resistance and turbulence, resulting in a quieter flush. The chrome center- mounted push button that sits atop the tank allows you to proactively conserve water by choosing between a 0.9 GPF rinse or 1.28 GPF for tougher jobs. The TOTO Aquia IV meets the standards for EPA WaterSense®, and California’s CEC and CALGreen requirements. The Aquia IV comes ready for install into a 12" rough-in, but may be adapted for a 10" or 14" rough-in with the purchase of a separately sold adapter. The Aquia IV bowl and tank set includes tank to bowl hardware, a tank to bowl gasket, outlet socket, and toilet bolt caps. Additional items needed for installation and use must be purchased separately: seat, wax ring, toilet mounting bolts, and water supply lines.

  • Excellent toilet
Style: Toilet
This is a great toilet. Less than a gallon of water used per flush for #1 and a little bit more for #2. It's pretty amazing how forcefully the water swirls when flushing. Less cleaning is required.

  • Update: from 1 star to 3 to 5! Toilet had arrived with corner broken off, new one sent FAST
Style: Toilet
Final update: replacement toilet came in less than a week; husband installed it yesterday, got the Toto Washlet bidet on earlier today (highly recommend the Washlet). Both work spectacularly! Yes, the lid of the tank just sits on top, doesn't overlap like other toilets: I assume that's because the flush buttons that communicate from lid to tank need it to be that way. We don't find it a problem. Toilet is low, comfortable; flushes strong and fast. It IS considered a very difficult toilet to seat; I wish we'd paid someone else to do it. Read instructions thoroughly first. Our instruction sheet was in the box with the tank; I don't know if we did that or the maker. But 2 friends said these toilets are difficult; one says he's installed about 25 so he should know. Update: I haven't heard back from the seller yet but it looks like the replacement I asked for is already on its way! I'll update again if that's true. First review: We love Toto toilets and we were excited to open the (slightly damaged) outer box yesterday, which had a big notice saying "This Side Up" on it. Inside was the Toto box with the toilet in it, with plenty of packing around that box. However, THAT box was ON ITS SIDE. We took photos of everything, including that little issue--which seems an issue given the "This Side Up" on the outer box. When we opened the Toto box, sure enough, a back corner had broken off the toilet into pieces, leaving an hole exposing a channel water runs through. It's not a small cosmetic problem: it's structural. I've written the seller for a replacement and will update this review upon getting that, and installing and using the toilet. ... show more

  • Make sure you know who is shipping this product.
Style: Toilet
I received this item via PlumberStock.com and needed to return it (with initial plans to exchange it for a version with a higher toilet bowl) as it looked great. To make a phone call with urgency and be told to submit an email AS I was giving the order number that the rep/employee who answered requested of me (it's a-relatively-expensive product and a toilet, so being able to quickly arrange getting the right version after returning this one so I could use it was key) was beyond rude and a waste of time. It read as the person changing their mind on helping me, so just know where this is coming from if you order it. My only main concern with the toilet was how small the tube (wrong term) that the waste would go through is, but couldn't test that out. The plumber said it was exceptionally small but acknowledged that Toto is a brand with great aesthetics and a good reputation, but it was worth noting that the size differential could present an issue down the line. ... show more

  • I wish I had purchased this a lot sooner
Style: Toilet
This is the second toilet we've replaced in our home. We purchased an American Standard H2Option for the previous toilet project, and it was $210. It's been fine, but I wanted to try a high end toilet this time, and I'm extremely glad I did: the Toto flush is 10x better - it's completely consistent, reliable, and even the smaller 0.9 gpf blows away any flush I've seen in any toilet. One note on the installation, as other reviewers have noted, it does not include an expensive part (somewhere between $80-$100) that is needed if your rough-in opening is not 12" on center. Ours was 14", and at first I panicked, but I did a little more research and decided that I could live with the toilet being 2" away from the wall. It ended up making the installation much easier, and doesn't look 'off' or bad at all in my opinion. I'm far from handy, and my wife and I got the entire project (including removing the old toilet) in about 3 hours. We transferred over our existing bidet seat and it works beautifully on the new Toto. Bottom line: Treat yourself - get this bad boy - you will be very happy every time you sit on the throne. ... show more

  • Missing hardware
Style: Toilet
Didn’t come with any hardware (eg trapfit) and Toto refused to ship it. They made me buy it, and all this delayed our remodel. Wouldn’t buy again

  • Cracked
Style: Toilet
I love the product but after I paid a plumber $150 to install it, we noticed it had a crack in the bowl. After spending over $500 for a toilet plus installation, I’m pretty disappointed that there is a crack. I’m not paying to have it uninstalled or going through the trouble of sending it back.
