TOTO S7A vs Bio Bidet BB-2000 - Bidet Seat Comparison

TOTO announced in June of 2023 that it would be discontinuing the fan favorite S550e Washlet and replacing it with the brand new upgraded TOTO S7A Washlet.

This new “best bidet seat money can buy” is now the most state-of-the-art TOTO bidet seat on the market.

The BB-2000 from Bio Bidet is another very popular bidet seat due to its variety of high quality features and very affordable price.

The brand new S7A Washlet from TOTO does have a number of advantages over the BB-2000 Bliss, as it’s a newly revamped product vs one that’s been around a few years now.

That’s not to say the BB-2000 can’t hold its own though. This luxury bidet seat from Bio Bidet still offers a surprising number of features and value for its price.

Let’s start off with the main areas of difference between these two units. 

The TOTO S7A and BB-2000 differ in seven main ways: 

  1. Price
  2. Seat height
  3. Components 
  4. Water heater type
  5. Features
  6. Wash pressure
  7. Warranty

Let’s get into each of these in more detail so you can find out which category is more important to you.

TOTO Washlet S7A vs BB-2000 - Price

Price is a pretty obvious difference between these two popular bidet seats. With the TOTO S7A being the most feature rich on the market, it definitely commands a much higher price than the BB-2000 from Bio Bidet.

Seat Height

Another important area in which these two models differ is seat height and general dimensions. The TOTO S7A is one of the sleekest seats on the market with a rear height of only 4.06”.

The Bio Bidet BB-2000 round size however is 5.71” in the back and elongated is 6" tall, so about a full two inches higher than the TOTO S7A. This can result in a less comfortable seating experience as the bulk in the back tends to push the user forward slightly.

The reason the BB-2000 has a taller, bulkier back area is because of the type of water heater that it uses. 

Bidet Water Heater

This is one of the main areas where the TOTO S7A and Bio Bidet BB-2000 Bliss differ. 

The BB-2000 has a hybrid water heating system, which means that it uses both a tank water heater and also has an inline heating element to supply unlimited warm water while it’s being used.

This system is much better than other electric bidets with just a normal tank water heater, which has a finite amount of warm water available. While the hybrid tank set up is better than just a standard tank heater, it’s still not ideal.  

The TOTO S7A on the other hand, has a tankless in-line water heater that supplies instant, unlimited warm water from the very start and never runs out. Because of the inherent nature of a tank water heater taking up space, the S7A Washlet is able to be much sleeker overall.

When people wonder why the TOTO S7A is much more expensive than the Bio Bidet BB-2000, this is one of the main reasons.

In order to have a seat as slim as comfortable to sit on as the TOTO S7A Washlet, you’d need an instant water heater and no tank, regardless of whether it’s hybrid or not.

Spray Nozzle

The spray nozzle on the BB-2000 is constructed of stainless steel and has a replaceable plastic tip on the end.

The TOTO S7A Washlet's bidet spray nozzle on the other hand, is composed of high quality antimicrobial plastic.

This is an area where the Bio Bidet BB-2000 definitely has the advantage. Plastic is obviously less durable and more sanitary than plastic, which can hide microbes in its more porous surface. 

Self Cleaning

The S7A Washlet uses EWATER to sterilize the wand, spray nozzle, toilet bowl and under the bidet seat before and after each use.

EWATER is electrolyzed water that has a lower PH than normal water and is a very effective cleaning agent. 

toto ewater feature explained

The Bio Bidet BB-2000 has a self cleaning feature but rinses the nozzle with regular water only before each use. The self cleaning feature for the BB-2000 only extends to the nozzle and not the toilet bowl or under the seat like the TOTO S7A. 

With the use of EWATER there shouldn’t be any real concern over cleanliness. As far as germs are concerned though, stainless is always better. 

Remote Control 

The remote control for the BB-2000 vs TOTO S7A has some differences worth noting as well. Both come with wireless remote controls, but since the S7A Washlet is brand new, there are some upgraded features that the BB-2000 lacks. 

The TOTO S7A remote is pictured below:

toto s7a washlet remote control

Some of the features that the TOTO S7A remote has that the BB-2000 doesn’t include:

  • 4 user memory presets 
  • Touch sensitive functionality
  • Larger, easier to use buttons

The buttons on the TOTO Washlet S7A remote control are definitely larger and more user friendly than the ones found on the BB-2000. For those with impaired vision or a disability, the TOTO S7A might be a better fit. 

The Bio Bidet BB-2000 on the other hand does have an "Auto" clean mode. This enables for a one-touch wash and dry feature, which the S7A Washlet does not have. 

You can check out the Bio Bidet BB-2000 remote control here:

Spray Pressure

While both the TOTO S7A Washlet and the Bio Bidet BB-2000 have excellent spray pressure, the BB-2000 has the advantage here.

With max rear and front spray pressure of 0.185 GPM, the BB-2000 has possibly the strongest spray pressure of any bidet seat on the market. 

Bio bidet bb 2000 nozzle

The S7A Washlet has a max front and rear spray pressure of 0.11 GPM in comparison. Still ample by any means but not as strong as the BB-2000. 

To recap, here’s the max spray pressure for each model: 

  • BB-2000 Max Spray Pressure : 0.185 GPM
  • TOTO S7A Max Spray Pressure : 0.11 GPM 

Enema Wash

While we’re comparing spray pressure between the BB-2000 vs TOTO S7A, we should mention that the BB-2000 also has an enema wash feature. Those suffering from constipation would benefit from this somewhat unique wash mode.

Enema wash sends a powerful stream of water into the user’s lower intestine in an attempt to loosen stool and stimulate a stubborn bowel movement. It might seem intense but we can assure you that this does in fact work.

Just be sure that you’re lined up properly!

The BB-2000 again has the advantage here with this feature as the TOTO S7A Washlet does not have this capability. For a list of all the bidet seats we carry with enema wash functionality, click here

Auto Flush Capability

Those interested in a bidet seat that also offers auto-flush will be happy to hear that the TOTO Washlet S7A has this capability, while the Bio Bidet BB-2000 does not.

Auto-Flush is a feature that enables a completely hands-off bathroom experience, along with the adjustable warm air dryer

Auto-flush uses a body sensor on the seat to detect when you’ve stood up and automatically flushes the toilet for you. This feature can also be used via the S7A Washlet remote control and can now be programed to flush only after the lid has been closed, an upgrade over the TOTO S550e.

A compatible auto-flush kit must be purchased and installed separately, or as part of a TOTO Washlet+ Combo

Warranty

The last major category that differentiates the TOTO S7A vs BB-2000 is warranty coverage. 

The Washlet S7A comes with a one year limited warranty, whereas the BB-2000 comes with a 3 year full warranty. There’s really no contest here as the Bio Bidet BB-2000 has the better warranty offer, hands down. 

TOTO however, is an industry leader in the bathroom and more specifically bidet category. You would be hard pressed to find a lot of unhappy TOTO bidet customers out there!

Seat Options

If you’re wondering if a Bio Bidet bidet seat or TOTO Washlet can be installed on any toilet, the short answer is no.

The TOTO S7A is only available in elongated size and won't fit round size toilets. 

round vs elongated toilet measurements

The Bio Bidet BB-2000 is available in both elongated and round size, so those with round toilets would still be able to install the BB-2000.

Neither of these bidet seats will fit on a toilet with what's known as a "french curve," so please make sure your toilet is compatible first.

When comparing these two bidet seats and the companies that produce them, what’s ultimately going to make you decide which one is right for you comes down to one or more of the major categories of differences we’ve laid out for you.
