Why should I choose the Bio Bidet BB-2000?

The Bio Bidet BB-2000’s number one strength is its ability to generate superior wash pressure.  High wash pressure is important in bidet toilet seats for more efficient cleaning, heavy / bariatric users, and the enema function.  It is the first bidet seat that offers both high water pressure and unlimited warm water.  It achieves this through its advanced hybrid water heating system that provides warm water from start to finish.  So, for users that value high wash pressure and a dedicated enema function, the BB-2000 is the best seat on the market. 

Besides its high wash pressure, the BB-2000 demonstrates its value with some luxury touches like a stainless steel nozzle and an LED night light.  The overall construction is very strong and the seat itself is one of the sturdiest available.   Bio Bidet backs up its flagship product with an industry best 3 year warranty that covers 100% of parts and labor.  

TOTO s350e Washlet

Why should I choose the TOTO s350e?

Because you want the best and nothing but the best.  TOTO is the biggest player in the bidet toilet seat market and its brand also carries the most weight.  TOTO uses the latest in bidet technology and their products set the industry standard for quality and functionality.  The s350e washlet is certainly no exception.  This model (along with the s300e) is the lowest profile bidet seat available at just 4” in height at the rear and its overall construction quality is best in class. 

The TOTO s350e’s auto open/close seat and lid is very convenient and gives this washlet the “wow” factor when users walk into the bathroom.  You can program it to automatically open just the lid or both seat and lid when someone gets near the toilet.  TOTO’s exclusive eWater+ feature uses electrolyzed water to spray your toilet bowl before and after each use—keeping it cleaner and free of debris.  Its warm air dryer is also the most effective one on the market today.  The only fault on that TOTO s350e is the short 1 year warranty for such a high price tag. 


The Bio Bidet BB-2000 and TOTO s350e are two luxury class bidet seats that represent the best of what their respective manufacturers have to offer.  Deciding which one to buy really depends on what the user values most in a bidet toilet seat.  If superior wash pressure and cleaning ability is what the user wants, then the BB-2000 is the clear choice.  If uncompromising quality and the “wow” factor are important, then the TOTO s350e is the best bidet seat money can buy.
