Dual Flush Toilet Toto Aquia Review 2024

If you are renovating your home and need an efficient and easy-to-clean toilet, the Aquia two-piece toilet should be on top of your list. Continue reading this review of the Toto Aqua toilet to learn more about the Toto Aquia toilet.

Quality and design

Toto produces some of the best toilet designs on the market. The Toto Aquia toilet is made of vitreous china material, with a chrome dual button flush trigger located at the top of the tank. The chrome buttons are not durable, and you may have to change them every year. Additionally, the toilet features a semi-skirted base which has the clean appearance of a skirted design but has no risk of interfering with the water supply pipe at the center of the wall.

The toilet seat is of the recommended height and ADA-compliant, but the flush lever isn’t, as it is located on the top of the toilet. If you have kids at home, then this toilet seat is not ideal for them but just for adults. The toilet is also very comfortable to use as it has an elongated bowl design.

Easy to install

If you know basic installation, there is no need to hire a professional plumber to install it for you, as the installation is straightforward and easy. The installation process is the same as the standard toilets. The toilet needs a 12-inch rough-in from the wall to the center of the waste pipe. Note that it has a 2,1/8-inch trap seal.

Since it is a two-piece toilet, there is no burden as you can easily lift the toilet seat alone and then fix the tank after tightening the screws. You will require items like toilet seat securing screws and the waste trap seal to finish the installation.

Easy to clean

Another feature that makes this toilet special is its ease of cleaning. You don’t have to clean the bowl surface after every use; a single flush leaves the toilet clean. Additionally, the toilet has an elongated bowl, which is easy to clean, and the white color can easily reveal where dirt and stains are for a sparkling look.

The semi-skirted design of the toilet not only makes it look good but cleaning outside is also made easy. You won’t have to brush around the crannies like in some toilets.

Efficient & Powerful flushing system

The Toto dual-max flushing system makes the Toto Aquia a perfect bathroom toilet. It allows the user to choose between 1.6 gallons of water per flush for a long call and 0.9 gallons of water per flush for a short call or liquid waste. Hence, no water is wasted, and it meets the EPA WaterSense requirements.

This powerful flush system is estimated to reduce your water consumption to 1.13 gallons per day. In some states, you might get rebates if you install the Aquia two-piece toilet. With such a low water consumption level, we can say the toilet is eco-friendly.

On top of that, it will take up less space as it is compactly made. So, if you want to have a modern look in your bathroom, this is a nice toilet to consider installing.

One year warranty

Some people might shy away from this toilet because it comes with a one-year warranty. But it is worth noting that despite Toto toilets offering just a one-year warranty on most of its products, they are very durable and proven to last for more than 10+ years. Thus, the warranty shouldn’t deter you from buying this quality toilet.
