The skirted design prevents stains

First and foremost, the toilet comes with a skirted design. This hides the trapway, which not only makes the toilet look lovely but as well as makes cleaning seamless. Besides, the toilet is made of vitreous china material, which is sturdy and easy to clean. So you will have an easy time cleaning the toilet surface and maintaining it. After all, it is also a one-piece toilet with no place for mold and mildew to hide. Also, the washlet G400 integrated toilet will provide you adjustable water pressure control system.

Effective Dual-Max 3D Tornado flush technology

Having a quality toilet is not enough if its flush system is not efficient. This is not the case with the Toto G400 Bidet toilet. It features dual-max 3D tornado flush technology. The tornado flush technology is very excellent in getting rid of waste from the toilet. It has three powerful nozzles that form a power centrifugal rinsing action to clear waste in the toilet bowl. In the process, it uses 0.9 GPF or 1.28 gallons per flush for liquid or solid waste, respectively.

Premist spray moist the bowl surface

Another exceptional function of the Toto G400 Washlet toilet is the Premist sprays. When the toilet lid opens automatically, the Premist sprays water on the toilet bowl surface before doing your thing. This helps to moisten the bowl surface so that waste and other particles can’t stick to it. As a result, this makes cleaning easy and keeps the toilet cleaner even when you’re done.

Cefiontect glaze makes it easy to maintain the toilet

Apart from having a Premist function, this unit also comes with the Cefiontect glaze that keeps the surface always clean. The Cefiontect glaze prevents substances from sticking to the toilet. This includes waste, mold, mildew, and even stains. In the end, this makes cleaning simple and straightforward.

Automatic open/close seat

What makes the Toto G400 toilet even more special is the hands-free operation. The toilet features an automatic opening and closing seat. The seat can automatically open as you approach the toilet. Also, when you finish your business, you can close it automatically. The toilet seat doesn’t slam, and it is a joy to sit on.

Heated seat for the winter season

One of the most challenging parts of using a toilet is during the cold season. But with this toilet, you will be able to use it comfortably all year round as it comes with a heated seat. The seat has an integrated sensor that maintains temperatures between 82 degrees F to 97 degrees F. It has five temperature settings that you can choose from for your comfort. So, no more cold toilet seats in the morning or during winter, as you can control the temperature and pressure setting while using.

Self-cleaning wand for hygiene

Older adults and those with disabilities may find it hard to clean their under. But with this toilet, they will not have to worry as the unit will do the cleaning for them instead of using tissue paper. This is not only hygienic but as well as preserves the environment as trees are saved.

The self-cleaning wand features three adjustable functions, which include rear, rear soft, and front. The rear function offers a pleasant and intense water pressure setting, while the soft rear function delivers a larger radius to cover a larger area. And finally, the front wash provides large and soft drops for comfortable, intimate cleansing.

Dryer and deodorizer to keep the toilet odor-free

Unlike regular toilets, this one features an air dryer and deodorizer. The work of the air dryer is to dry your under after the self-cleaning wand has done its job. So, you will leave the toilet very clean and with no traces of water on your under.

On the other hand, the deodorizer gets rid of the foul smell, thus, leaving the toilet smelling fresh and ready for use.

Hand-free automatic flushing technology

As we stated earlier, this is a hands-free toilet. Meaning that you don’t have to touch the toilet to use it. With simple remote control, you get to control the toilet as you go about your business. One of the features that you can command is the automatic flush. As soon as you stand up from the toilet, it will flush automatically.

ADA-compliant is ideal for all users

What’s more, the Toto G400 Washlet bidet is a comfortable toilet as it is ADA-compliant. This means that people of different ages will have an easy time sitting on or standing up from the toilet. Besides, it comes with an elongated bowl design that provides more sitting space. So, it is more comfortable than a round bowl toilet.

What are the alternatives to Toto G400 Toilet?

Compare with the Toto G500:

People often make mistakes choosing between G400 and G500 because they think G500 is more advanced. But the Toto G400 is the upgraded version and is cheaper than the Toto G500. However, there are lots of similarities between them, like water usage, modern design, hand-free operation, etc. The main differences between them are in their flushing systems, weight, and prices. The Toto G500 is lightweight and compact in design. So the toilet is ideal for a small bathroom. Also, the G500 comes with a cyclone flushing mechanism, which is less powerful than the G400’s 3D Tornado Flush. That’s why G400 needs less water to evacuate all the waste in a single flush.

Toto Ultramax II Toilet:

If you are a budget shopper and can’t afford the Toto G400 toilet, then the Toto UltraMax II would be the best alternative. The toilet doesn’t offer advanced features like a heated seat, an auto-open lid, or an air deodorizer, but the overall features are quite the same. The Tornado flushing mechanism on the toilet uses 1.28 GPF of water per flush. The toilet has a CEFIONTECT Glaze finish that prevents stains, bacteria, and mold from sticking to the toilet surface. The universal height design and soft-close seat make it ideal for all users of all ages.

Toto G400 Vs. Toto Neorest:

Toto’s Neorest series is more advanced and costly than the G400. The toilet has a dual flushing mechanism that allows you to choose between 0.8 and 1.0 GPF. Unlike the Toto G400, the Neorest is EWATER+ certified, which means the cleaning agent cleans the nozzle automatically after each wash. For night use, the toilet has beautiful illuminating lights with unlimited warm water. But to get all these additional features, you have to spend a little more than the Toto G400 toilet.

Bottom line

The Toto Washlet G400 Bidet toilet seat with an integrated dual-max flushing system is a luxurious and powerful unit. Not only will it change the look of your bathroom, but the experience as well. The toilet will also help you to maintain a high level of hygiene by not using toilet paper. Similar to other top-end toilets, the G400 bidet toilet offers you comfort, and you can use it no matter the season of the year. This is because of its heated seat with five temperature settings.

Besides, the toilet is very comfortable and straightforward to clean. Overall, this is a perfect toilet for people who want luxury and convenience in their bathroom. Toto is a famous brand and offers quality toilets. So, expect this toilet to last for a very long while. I hope you have got a clear idea after reading this Toto G400 review article.


Question: Can I install the Toto G400 toilet?
Answer: Yes, you can. However, installing this toilet is quite cumbersome and time-consuming. Unlike a regular toilet, the Toto washlet G400 integrated toilet is quite heavier; thus, you may need the help of another person to install it securely. The good news is that it comes with a toilet seat, and you won’t have to buy a separate toilet seat.

Question: Is it possible to replace this toilet with another bidet model?
Answer: If the toilet seat gets damaged or breaks accidentally, you can get a replacement immediately. However, you cannot install another seat model that is not a G400 bidet. So, the answer is you cannot replace it with another type of toilet seat like with regular toilets.
