TOTO CST416M-01 Aquia II 2-Piece Toilet Review

Have you heard of the washlet? Perhaps you have not or probably you have experienced it but you don’t really know what it is. Either way, let’s give you a brief description. It’s a popular toilet technology in Japan that uses features like a small panel for the settings (especially for flushing), a steady stream of jet water for cleaning the butt, heated toilet seats. It’s actually a beautiful toilet that many Americans would love, and we bet that you’re thinking the same way too. That’s why we’ll also be talking about Toto Aquia II 2-piece Toilet.

Toto is a Japanese company, and how it relates to washlet is pretty simple: it manufactures them. The good news is you don’t have to order something similar in Japan as you can already buy them in Amazon.

Design and Installation

The Aquia II toilet has been designed to be closely related to the toilet bowl you used to know. In fact, it shares the same dimensions as your toilet seat (the initial purchase doesn’t come with it). Its size is also perfect for retrofitting even if it seems longer or more elongated than traditional bowls. In other words, you don’t have to perform massive changes in plumbing before you can adopt it into your home or even business space. This smart design can be partly attributed to the company’s vast experience in the plumbing industry.

It has a total height of around 15 inches, which makes it a very comfortable height for Americans who are significantly taller than the Japanese, and children who are at least 7 to 8 years old wouldn’t have an issue sitting on it. With the seat, it tends to increase to an inch.

Performance and Efficiency

The toilet has a dual-flush system that uses water economically. Represented by two buttons (so no more touching and holding on to levers), these are high volume (lots of water) for fecal matter and low volume for your urine. This is very important since you want the entire waste to go down. Definitely low volume doesn’t really work like a charm with stool. With this toilet, the water pushes down the waste effectively as well as rinses the bowl entirely.

Now one of the greatest complaints people have about flushing, in general is it tends to get noisy, as if informing anyone who gets to hear it that you’ve been in the toilet. Although doing so is as natural as eating, it can still be pretty embarrassing even when you’re in your home.

The Toto Aquaia II toilet is efficient not only in water consumption but also in its level of noise. It still produces sound, but it’s relatively quiet than most of the other toilets in the market.


The toilet is a beautiful-looking them. It’s sleek and contemporary and doesn’t occupy too much space. But more than its design, it is also very durable. On the average, it can still be in great working condition after 3 to 5 years.
