Detailed Comparison of the Bio Bidet A8 Serenity and the TOTO S550e Washlet Bidet Seats

The Bio Bidet A8 Serenity and the TOTO S550e are both state-of-art bidet seats that feature some of the best technology on the market today. While you can't go wrong with either choice, we will detail the differences in these to models so you can choose the best product for you and your family.

Design

For ultimate comfort, cleanliness and style, both the Bio Bidet A8 Serenity and the TOTO S550e features beautiful construction alongside top-tier features. The Bio Bidet A8 has a modern and luxurious design and is available in a classic white color. In contrast, TOTO offers the S550e in two different trim options. Easily match your style and bathroom decor by choosing the S550e in either the classic beveled trim or the sleek contemporary trim. In addition to white, the S550e is also available in beige.

Nozzles

The Bio Bidet A8 comes with a single 2-in-1 stainless steel nozzle, while the S550e has a single plastic nozzle. Stainless steel is the more durable and long lasting of the two materials, and it is also a more hygienic choice because it’s resistant to bacteria growth. Comparatively, The S550e does offer nozzle sterilization with Ewater + for protection against germ build up.  Nozzles on both seat models utilize great features like self cleaning, adjustability and oscillation.

It's also worth mentioning that the nozzle on the A8 also has the ability extend the water stream a bit further than the S550e for maximum cleansing coverage.

Lid

Both the TOTO S550e as well as the Bio Bidet A8 offer the convenience of a soft closing lid. This is a great feature to ensure your seat won’t be damaged by lid slamming. Additionally, The S550e goes a step further and offers an automatic lid opening function. While this feature is incredibly impressive and handy, the auto open can be turned off if desired.

Weight Limit

The TOTO S550e can accommodate up to 320 lbs, while the Bio Bidet A8 has a higher limit of 400 lbs.

Wash

Both of these seats offer high quality wash options for an enhanced bathroom experience. Some of the features that both the A8 and S550e offer include: front and rear washes, adjustable water temperature and pressure, wide spray for more coverage, and pulsating spray stream that both soothes and stimulates the bowels.  

One Button Wash and Dry

For simplicity, the A8 offers the convenience of a one button wash and dry. If you happen to be in a hurry and don’t have time to configure multiple settings, you can choose the auto wash and dry with just the touch of a button. This is also a great feature for older users who are looking for a way to experience all the benefits of a bidet seat but don’t want the hassle or inconvenience of messing with numerous buttons.

Water Flow

The TOTO S550e utilizes a standard water flow rate of 0.1 gallons per minute, while the Bio Bidet A8 offers a higher flow rate of 0.18. A higher water flow rate produces a more powerful stream and therefore results in a faster cleansing process. Although the Bio Bidet A8 offers nearly double the water flow as the TOTO S550e, the nozzle spout is a bit wider so it does not result in twice the water pressure.

Through aeration, the A8 also offers the ability to control the power of its wash without changing the water flow. Aeration, which is the infusion of bubbles into the water, can be turned on for a more powerful stream and turned off for a softer, gentler wash.

Other Differences

Child Mode

For those with children who may also benefit from using the bidet seat, the A8 offers a child mode function which provides a gentle wash specifically designed for youngsters. The S550e does not offer a child mode function.

Warranty

Users who desire a lengthy warranty will be impressed by Bio Bidet’s 3 year full warranty for the A8 Serenity that can also be upgraded to an impressive 6 years. Alternatively, TOTO offers just a 1 year full warranty with no option to upgrade.

Final Thoughts

Both the Bio Bidet A8 Serenity as well as the TOTO S550e will turn any regular bathroom into a luxurious, spa-like experience. With so many wonderful and similar features, whether you choose the A8 or the S550e will depend on your personal needs, design preferences and how long you want your warranty to last. Regardless of your choice, you will be taking a wonderful step towards a comfortable and supremely hygienic bathroom routine.
