Detailed Comparison

Look & Feel

The TOTO S550e is designed specifically for elongated toilets, and it’s easy to match with nearly any bathroom as it comes in two design options (classic or contemporary) and two color options (white and beige). The lid of the S550e Classic features an elegant beveled edge, whereas the lid of the S550e Contemporary is sleek and angular for a more modern look. In comparison, the Cascade 3000 by Dignity Solutions comes only in white and its sophisticated design is similar to that of the TOTO S550e contemporary. The Cascade 3000 is compatible with a greater range of toilets than the S550e as it comes in both elongated and round seat styles, plus its design allows it to be successfully installed on difficult-to-fit French curve toilets.

Sittable Lid

The lid of the TOTO S550e cannot support the weight of an adult due to the technology housed within the seat’s casing, and sitting on it carries the risk of seriously damaging or breaking the seat. This poses a challenge for individuals who habitually sit on their toilet lid to complete personal hygiene activities or to assist someone in bathing. On the bright side, the Dignity Solutions Cascade 3000 is one of the few bidets on the market that features a durable, sittable lid that is capable of safely supporting up to 330 lbs.

Wash & Dry Features


The Cascade 3000 by Dignity Solutions features a top-quality, stainless steel nozzles. Compared to plastic or aluminum, stainless steel has long been considered the industry gold standard for nozzle construction due to its durability and bacteria resisting properties. In comparison, the TOTO S550e comes with a plastic nozzle. Additionally, it’s worth noting that both units feature nozzle sterilization technology. The main difference is the type of sterilization method used. The Cascade 3000’s interior tubing and nozzles are coated with silver, which has natural antibacterial properties and prevents the interior surfaces from becoming contaminated. This keeps the water pure as it passes through the unit, and this clean water is then used for the front and rear washes, as well as for rinsing the bidet’s nozzles after each use. The TOTO S300e, in comparison, uses sterile, electrolyzed water to sanitize the unit’s nozzles.

Wide Spray

The TOTO S550e comes with an impressive four wash modes: front, wide front, rear and soft rear. Wide front cleansing, in particular, is a feature not found on many units. As the name implies, wide front cleansing broadens the water spray, thereby increasing the wash coverage area and reducing the amount of shifting necessary to achieve a thorough cleanse. In comparison, the Cascade 3000 features two wash modes, front and rear, with no wide spray option.

One Button Wash/Dry and User Presets

The Dignity Solutions Cascade 3000 comes with an auto wash/dry feature that, as the name suggests, initiates a standard wash and dry cycle at the touch of a single button. While the TOTO S550e doesn’t have a one button wash, it does feature two user presets. User presets allow you to program your favorite wash settings into the remote ahead of time, so two people can save their customized settings.  The Cascade 3000 on the other hand defaults the the last settings used.

Comfort & Convenience Features

Auto Open/Close Lid

The TOTO S550e features a sensor that detects when someone approaches or walks away from the seat and raises or lowers the lid accordingly. This impressive feature makes using the restroom a bit simpler and is sure to wow your guests. The Cascade 3000 by Dignity Solutions doesn’t feature an auto open/close lid, but does offer slow closing.

Remote Options

The TOTO S550e comes with an attractive, dual sided remote with a screen for displaying selected options. The Cascade 3000 by Dignity Solutions, on the other hand, offers two remote options: a large remote with easy-to-press buttons and an intuitive layout, or a smaller (standard size) remote with flat buttons and a screen that displays chosen options.

Weight Limit

The TOTO S550e is able to safely support up to 320 lbs, while the Dignity Solutions Cascade 3000 isn’t far behind, with a 350 lb weight limit.


Dignity Solutions offers a full 4 year warranty on the Cascade 3000, giving you peace of mind knowing that your investment is protected for several years to come. In contrast, the TOTO S550e features a 1 year full warranty. If having a longer warranty is important to you, the Cascade 3000 won’t disappoint.

Final Thoughts

Both the TOTO S550e and the Dignity Solutions Cascade 3000 have a lot to offer, both visually and functionally. From a features and looks standpoint, the TOTO S550e offers slightly more as it’s available in two colors and two styles, and features an auto open/close lid, customizable user presets, slightly higher weight limit, and four wash modes (including wide front washing). From a practical standpoint, however, the Cascade 3000 by Dignity Solutions is the more versatile unit as it comes in both elongated and round seat styles, features a design that’s compatible with difficult-to-fit French-curve toilets, offers a four year full warranty, and comes with a convenient, sittable lid along with high-quality stainless steel nozzles. Ultimately, your personal preferences and priorities will be your best guide in determining which unit is better for you.
