TOTO G450 vs S7A Washlet: Which One is Right For You?

Are you looking for a new bidet toilet but aren't sure whether to look into an all-in-one unit or add a Washlet to a traditional toilet?

Our guide to the TOTO Washlet G450 vs Washlet S7A will help you decide.  

TOTO G450 vs S7A

Before we really get started, we need to mention that the TOTO G450 was replaced by the upgraded TOTO G5A. If you'd like to know how these two compare, you can read all about that here. 

The TOTO Washlet G450 is the most affordable option when looking at other Neorest bidet toilets.

Although TOTO confuses things by calling this a “Washlet,” when it really is more in line with its other smart bidet toilets. 

The TOTO S7A on the other hand, is the most expensive in the line of bidet seats that bear the name Washlet. It’s also considered the new “best bidet money can buy” after replacing the Washlet S550e.

So how do these two popular products compare to each other? Read on to find out in our complete guide to the TOTO G450 vs S7A.

TOTO Washlet G450 Explained

So what's the difference between the TOTO G450 and a Neorest?

As we mentioned earlier, this can be a confusing topic.

On its website, TOTO calls the G450 Washlet an “Integrated Smart Toilet” which is exactly what it is. 

For those that don’t know, TOTO calls a bidet seat a Washlet and an Integrated Bidet Toilet a Neorest.

TOTO G450 vs S7A - Differences

So what are these two products and how are they different? 

The main areas where these products differ are:

1. Self-Cleaning
2. Auto-Flush
3. User Presets
4. Color options
5. Price
6. Installation

We’ll go into more detail about each of these and explain what all of them have to offer. 

EWATER 

One of the only cleaning feature differences between these two is the extra EWATER rinse that the TOTO S7A gets underneath the seat. This is a new, upgraded feature from the S550e Washlet. 

EWATER is electrolyzed water that has a lower PH and is very effective with cleaning surfaces without the use of harsh chemicals. It’s safe to touch and is used in food production plants as well.  

Both the TOTO G450 and the S7A Washlet use EWATER to clean the toilet bowl and bidet wand, but the Washlet S7A gets an extra rinse on the underside of the seat that the TOTO G450 doesn’t have. 

Auto-Flush

Have you ever wished there was a toilet that could flush itself? With TOTO’s line of smart bidet toilets, that dream becomes a reality. 

The Washlet G450 has the Auto-flush feature included, as do all the other Neorest models.  

While the TOTO S7A is auto-flush compatible, unless it’s ordered as part of a Washlet+ combo, an auto-flush kit is not automatically included. 

So while you can definitely still have the auto-flush feature with the TOTO S7A, it just doesn’t always come with it. 

As far as overall TOTO Washlet compatibility and auto-flush is concerned, the only Washlets that are able to use this feature are the TOTO S7 and S7A.

Now, if you were to order something like the TOTO Nexus Washlet + S7A, then the auto-flush kit is included with that SKU and you’re good to go. 

Because the TOTO S7A is replacing the Washlet S550e, there are new auto-flush kits that you’ll need to be aware of. For all the new auto-flush kits that are only compatible with the S7 and S7A Washlets, click here. 

User Presets

The brand new TOTO Washlet S7A has a newly upgraded remote control that allows for up to four user’s memory settings to be stored. That means that multiple household members can store their own personalized settings or you could even have different settings for the different seasons. 

The G450 Washlet allows for users to store their settings as well, but only offers the standard two user presets found in other Neorest models like the TOTO RH and Neorest AH models. 

Color Options

If you're looking for a bidet product in a color other than cotton white, the TOTO Washlet S7A in Sedona Beige might be the deciding factor here.

You can pair the Sedona beige S7A Washlet with a compatible sedona beige TOTO toilet.

While the TOTO Washlet G450 is only available in white, there are some other Neorest options in sedona beige like the Neorest RH and Neorest AH. 

These Neorest models in sedona beige are being discontinued though, so they will only be available as supplies last.

TOTO G450 vs S7A Price

Because these two products are fundamentally different, there is a difference in price to consider. 

With the Washlet G450 Integrated Smart Toilet, you’re getting an entire bathroom fixture. Whereas with the TOTO S7A, you’re just purchasing a bidet seat that will replace your current toilet seat. 

Which one do you think is more expensive?

TOTO G450 Installation

Because you are getting an entire toilet, the installation for the Washlet G450 is going to be more involved than with the TOTO S7A which just replaces your toilet seat. 

The TOTO G450 manuals for use and installation are included below:

• TOTO Washlet G450 User Manual
• TOTO Washlet G450 Installation manual 

Neither are overly complicated to install, but there are more dimensions and specifications to consider with the TOTO G450. Comparing the TOTO G450 specs vs S7A specs is important here when considering which one to buy. 

The product specification sheets for each are included below:

• TOTO Washlet G450 specification sheet 
• TOTO Washlet S7A specification sheet 

TOTO S7A vs Washlet G450 - Similarities

Besides those differences, the main bidet cleaning functions of both the Washlet S7A and TOTO G450 are basically the same. 

The main cleaning and convenience features that both products share include: 

• Auto open/close lid
• Heated seat
• Instant/unlimited warm water 
• Premist of bowl before use
• Auto-flush (the S7A is auto-flush compatible but it’s not included)
• Air deodorizer
• Adjustable spray position
