Detailed comparison of the TOTO S550e WASHLET and Bio Bidet dib-850 seats
Both the TOTO S550e and the Bio Bidet dib-850 offer top of line features for comfort and design and would be a great addition to any bathroom. Below we walk through the differences in these units so you can make the best purchase for your preferences and situation.
Look and Feel
Style Options
If you are looking for design options, The TOTO S550e is available in two different trim options, classic and contemporary, as well as two color options to match your style preferences. The Bio Bidet dib-850 is only offered in one trim and color option, but offers a sleek, modern look as well as a seat that is contoured for ultimate comfort.
Convenience
While both the TOTO S550e and the Bio Bidet dib-850 offer great features like an adjustable heated seat, warm air dryer, LED night light, wireless remote, and built-in deodorizer, there are some design differences between the two.
Lid
If a sittable lid is an important feature to you, the dib-850 will be your best option in this situation, as the S550e does not offer that feature.
Auto Open and Close Lid
The TOTO S550e also features an automatic opening and closing lid, while the Bio Bidet dib-850 only can auto close. Depending on your preference, these features can also be turned off and the lid can be opened and closed manually.
Wash
Nozzles
The S550e offers a single nozzle system made of plastic that is unfortunately not easy to replace, while the dib-850 features a single 3-in-1 stainless steel nozzle that is easily replaceable when necessary. It’s also worth noting that the TOTO S550e nozzle system offers on demand sterilization with EWATER+ (electrolyzed water) while the the Bio Bidet dib-850 does not.
Enema Wash
The TOTO S550e and Bio Bidet dib-850 each have features that provide a great, comfortable wash, but if constipation is something you struggle with and you are looking for an enema wash feature, the dib-850 is the seat for you.
One Button Wash & Dry
The Bio Bidet dib-850 offers the convenience of a one button wash and dry feature, while the S550e does not.
Other Differences
Warranty
The Bio Bidet db-850 offers a 3 year full warranty that can be extended to 6 years if you are looking for extra coverage, while the TOTO S550e only offers non-upgradable 1 year full warranty.
Final Thoughts
Both of these seats would be great addition to any home, but determining which is best for you comes down to your individual needs and preferences.
If an enema wash or a sittable lid are must have features, then the Bio Bidet dib-850 will be your best option. On the other hand, if an automatically closing and opening lid and nozzle sterilization is important to you, you will want to consider the TOTO S550e. Either way, you will be getting a modern, and top of the line quality seat for your specific needs.
