TOTO Neorest AS vs LS: The Differences Explained
Are you looking into the differences between the TOTO AS vs LS? We have all the information you need.
The Neorest AS and Neorest LS share identical cleaning features, but the LS has a porcelain toilet bowl, a curvier and more luxurious design, a larger seat area, and three trim color options (silver, black, and nickel).
The TOTO AS has plastic side panels, a more angular look, and comes only in the standard color at a lower price. Choose the LS if you want extra seat room and a more premium look, and choose the AS if you want to save some money without giving up any cleaning features.
Both models replaced older Neorest units in 2023, with the AS replacing the Neorest AH and the LS replacing the Neorest 700H.

While there are some differences, you should know that these two Neorest toilets are very similar when looking at certain areas..

That being said, there are three distinct areas where these two new TOTO Neorest toilets do differ:
- Design
- Dimensions
- Price
We’ll go into each of three categories in more detail so that you can make the best decision for your home or business.
Design
What immediately sets the TOTO Neorest LS vs AS apart is the appearance.
The Neorest LS toilet lid has some slight waves and smooth curves.
The Neorest AS on the other hand, is a bit more angular and utilitarian.
The bowls on each Neorest are different as well, where the Neorest AS bowl is a bit straight and tight and the Neorest LS angles out more where it meets the seat.
Also important to note, the Neorest LS toilet bowl is composed of porcelain, whereas the Neorest AS has plastic side panels held on by magnets.
The TOTO LS definitely stands out in this regard as having a more luxurious look and feel.
Color options
Another design difference between these two models is the ability to have different trim and remote control color options. These color options are only available for the Neorest LS.
The TOTO Neorest LS has three color options:
- Silver
- Black
- Nickel
The silver color option comes standard and the black and nickel are a step up price-wise, but we’ll get to price later.
TOTO Neorest Dimensions
This is an area where you will want to make some careful considerations. The dimensions are important, not just for knowing how these Neorest toilets will fit in your home, but also for your seated comfort.
The seat area on the Neorest LS is both wider and longer.

Neorest LS seat area:
- 28.56” long
- 16.19” wide
The seat area on the Neorest AS is a bit shorter and thinner than the TOTO LS.

Neorest AS seat area:
- 27.25” long
- 15.19” wide
That may not seem like a lot when you first look at those numbers, but when you’re sitting down and using the seat everyday, every inch counts.

Price
The various design and dimension differences all lead us up to consider price, as this is another important area of difference.
While not wildly different in price, the TOTO LS is more expensive than the Neorest AS. The main reason for this is because of the additional seat room found on the Neorest LS vs AS.
This is actually the main difference between all of the new Neorest models. The TOTO RS is the smallest and slimmest and costs the least, where the Neorest LS is a larger unit with a more comfortable sitting area.
If you’re a larger person, then you’re probably going to want the additional seat area that the Neorest LS provides.
If you’re more on the petite side and you like the look of the Neorest AS or RS, then those models might be the right choice for you.
That’s not to say that the Neorest LS is only for larger users or that the Neorest RS and AS aren’t comfortable to sit on. The additional seat area would work out well for anyone, but especially if you know you need a few extra inches here and there.
