Detailed Comparison

Look & Feel

The TOTO S500e fits elongated toilets, and it comes in two design options (classic or contemporary) and two colors (white or beige). The lid of the S500e Classic features an elegant beveled edge, whereas the lid of the S500e Contemporary is sleek and angular, giving it a more modern look. The Cascade 3000 by Dignity Solutions comes only in white and features a sophisticated design similar to that of the TOTO S500e contemporary. It’s worth mentioning that, compared to the S500e, the Cascade 3000 is compatible with a wider range of toilets as it comes in both elongated and round seat styles and its design allows for successful installation on difficult-to-fit French curve toilets.

Sittable Lid

Like most bidets on the market, the TOTO S500e’s lid can’t support the weight of an adult, and sitting on it carries the risk of seriously damaging or breaking the bidet. If you like to sit on your toilet lid to clip toenails or to assist someone in bathing, the Cascade 3000 bidet seat is a good option for you as it comes with a durable, sittable lid that safely supports 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 easiness to clean. In comparison, the TOTO S500e has 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 S500e, in comparison, uses sterile, electrolyzed water to sanitize the unit’s nozzles.

Wide Spray

The Dignity Solutions Cascade 3000 offers two wash modes (front and rear) whereas the The TOTO S500e offers four wash modes (front, wide front, rear and soft rear). Wide front cleansing, is a particularly useful feature as it broadens the water spray and increases the wash coverage area, minimizing the amount of body repositioning required for a comprehensive cleanse.

One Button Wash/Dry and User Presets

The Dignity Solutions Cascade 3000 gives users the option of manually selecting their desired wash and dry settings or to initiate a standard wash and dry cycle at the touch of a single button. When starting a wash, or running the auto wash, the Cascade 3000 uses whatever settings were used last unless the operator adjusts the settings. The TOTO S550e offers a similar, albeit more versatile, feature called “user presets”. User presets allows you to program two sets of favorite wash and dry settings into the remote ahead of time, so it doesn’t necessarily have to default to simply the last settings used.

Comfort & Convenience Features

Remote Options

The TOTO S500e 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 S500e is able to safely support up to 320 lbs, while the Dignity Solutions Cascade 3000 isn’t far behind, with a 350 lbs weight limit, but also allows you to sit on the lid.


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 S500e features a 1 year full warranty. If having a longer warranty is important to you, the Cascade 3000 won’t disappoint.

Final Thoughts

The TOTO S500e and the Dignity Solutions Cascade 3000 each bring a lot to the table when it comes to looks, quality, comfort and convenience. The TOTO S500e offers a few more features than the Cascade 3000, to include soft rear and wide front wash modes, two color options, two style options, user presets, and a slightly higher weight limit. That said, the Cascade 3000 offers several desirable features not found on the TOTO S500e: stainless steel nozzles, a sittable lid, elongated and round seat options, a four year full warranty, two remote styles and a design that is compatible with French curve toilets. Only you can decide which unit offer the features that best meet your needs!
