Differences between the Toto Washlet G500 and G400


The Toto G400 comes with an extra feature which is the PreMist. This function uses incoming water supply and a premist wets the toilet bowl surface. In return, it helps get rid of waste, approximately 80% more effective than a dry bowl.

Allows the user to select volume

Apart from the PreMist, the G400 also allows the user to select the volume of water to use for flushing the toilet. This is not the case with the G500 which makes the choice after you stand up from the toilet bowl. As a result, you may end up saving more water.


Pricewise, the G500 is more expensive when compared to the G400 because of its old production cost. The features in these two models are almost the same, but G400 features are slightly advanced.

It is also worth noting that the G400 is slightly heavier than the G500 toilet. But, you will not face any challenge to install G400 or G500 toilet because of their straightforward installing process. And no need a professional plumber to install them.

Which is better? Toto G400 OR G500?

Both toilets share the same features and have similar performance. But, It is not difficult to decide which one of these two toilets is better. The G400 has PreMist feature, and it is the improved version of the G500. And the G400 toilet price slightly cheaper too. Thus, I will recommend the Toto Washlet G400 one-piece toilet. While for those who are ready to spend a little bit more for the most popular Washlet version, I will suggest the Toto Washlet G500 one-piece toilet.
