In my previous product review, I listed the top models of complete luxury toilets.
But what if your toilets are already top-notch, and you just want to retrofit them with a state-of-the-art electronic toilet seat?
Here I assume you are shopping for a seat instead of a complete toilet, and focus on electronic bidet toilet seats.
There are many manufacturers of bidet seats and each has many models. This is a very confusing starting point.
So here is my simple methodology to strive to reach good conclusion: For each manufacturer, I will choose their best model, which is easy in most cases because most manufacturers do know and want to tell us that (but not all of them!), and in the second step I will compare the top models between manufacturers.
Prerequisites: What to Check to Make Sure It Will Fit
First things first: you need to have an electrical outlet in your bathroom, or be ready to have an electrician come install one.
Next, the toilet seat has to fit your toilet. There are two common standard types: round/D-shape and elongated, and most manufacturers offer each of their model in both sizes. We will not consider the non-standard sizes. Round and D-shapes are similar, with the difference being the straight edge of the toilet seat on the side of the toilet tank.
Note that elongated models are much more comfortable for males as well as for larger people in general, besides their more stylish look. This surely explains why most luxury toilet illustrations are of the elongated type.
For North American toilets, here are the measurements that help you check if your existing toilet is of the standard type:
Distance between centers of bolts for the seat attachment: 5″1/4
Distance from to reservoir: at least 1″1/2.
As for choosing whether your existing toilet needs and elongated or a round/D-shape seat, you would measure the distance between the center of the bolts and the front edge of the bowl. If it’s longer than 18″, up to 19″1/4, it is elongated; if it’s less, down to 16″, it’s the D-shape (or round) version that you need.
My list of top models from the main manufacturers
Note: most prices are from Amazon, typically with a large discount from the manufacturer’s price. Links to actual products coming soon!
- Toto washlet S550e (white or beige)
- Brondell Swash 1400 (white or biscuit)
- BioBidet BB2000 (white or beige)
- Alpha JX (white only)
- Euroto EUT3618 (elongated and white only)
- Blooming BL-1063
- Kohler Novita BH90. Note: Novita is a South Korean company that merged with Kohler.
Ove: although an interesting option for complete smart toilets, it does not sell toilet seats, only complete toilets.
Here are many other brands we will not review: GenieBidet, Luxe Bidet, Smart Bidet, Lotus Hygiene, Infinity Bidet, Inus, Living Star, Tushy, American Standard.
They surely offer great value for money, but they are not in contention for claiming a complete set of features.
However, I concede that Lotus Hygiene ATS-1000 is an interesting top model worth considering, but I haven’t found enough comparison information.
Comparison Between the Top Models
To begin, it should be said that all the above models are excellent choices, all with a fairly complete list of features of what you would expect an electronic toilet to be capable of.
Be realistic though, as none will actually brush your teeth 😉
Each manufacturer has engineering and implemented the key features differently, targeting its own niches in the market.
This makes a direct comparison between models fairly difficult.
As the leading innovator in the industry, Toto really stands out from the pack.
Its top washlet has a number of unique features: toilet bowl misting and ewater (electrolized water) for better cleaning, and the generic features are typically more advanced in the Toto toilets.
If they are essential for you, then by all means go for the Toto washlet.
A List of Differences Between Washlet Seat Functions
Only Toto and Kohler have automatic opening and closing of the lid.
Toto, Brondell and BioBidet have user preset preferences.
Also, only Toto and Brondell have a broad spray washing function.
In the above list, Toto comes out on top. But now please note the following features for which other manufacturers beat Toto:
If a stainless steel nozzle is a key feature for you, then do note that Toto washlet S550e does not have it. Alpha has an aluminum nozzle, the other manufactures all have stainless steel.
If user weight exceeds 300 lbs, and up to 450 lbs, the only model that meets the weight requirement is BioBidet BB2000.
The Toto washlets have only 1 year warranty, while Alpha, BioBidet, Blooming and Brondell offer 3 years or somewhat longer. These last three models are also offered under a free 30-day trial, but not Toto.
If you are looking for an enema wash, then only BioBidet features it. Along this line, the Toto cleaning jet has a maximum volume of up to 0.4 liters per minute, while BioBidet and Blooming offer a greater delievery volume of nearly twice as much, at 0.7 l/min.
If you want a bidet seat that you can sit on with the lid closed, then only the Brondell model has this sturdiness built-in.
Finally, the Alpha and the Novita are the only models with a one-button easy wash, or a one-button wash and dry for simple use.
In summary, all these models are excellent but each has its own strengths and downsides.
If you want the most features, the Toto S550e is the best option, but BioBidet and Brondell come very close.
I could not say much about the Euroto model, which looks full-featured at first glance, but is a very new player in the industry, and should be worth your serious consideration.
An important consideration which I have not addressed here in depth is the overall design: of course this is a matter of taste and preferences.
However, I’m confident that you’ll find most models listed here to be quite aesthetically pleasing.
If you have questions about special features that I have not covered, or found some mistakes or omissions, or anything else, please leave me a comment, and I will update the page with more accurate information.
