Detailed Comparison between the TOTO S350e Washlet and the Dignity Solutions Cascade 3000

Look & Feel

The Cascade 3000 by Dignity Solutions features a classically elegant design and is available in a crisp white color. It’s a very versatile seat as it comes in both elongated and round seat styles and its design enables it to be successfully installed on French curve toilets. The TOTO S350e features a similarly sophisticated look but only fits round toilets. It does come two color options, white or beige, making it easy to match with most bathroom color schemes.

Sittable Lid

Like most bidets on the market, the TOTO S350e’s lid isn’t designed to support the weight of an adult, and sitting on it carries the risk of seriously damaging or breaking the bidet. In contrast, the Cascade 3000 by Dignity Solutions comes with a durable, sittable lid that safely supports up to 300 lbs, so it’s a great option if you regularly sit on your toilet lid to dress or complete personal hygiene activities like clipping toenails.

Wash & Dry Features

Nozzles

The Cascade 3000 by Dignity Solutions features a top-quality, stainless steel nozzles. Despite the fact that most bidet seats on the market have plastic or aluminum nozzles, stainless steel has long been considered the best for nozzle construction due to its durability and bacteria resisting properties. Unlike the Cascade 3000, the TOTO S350e is equipped with a plastic nozzle.  Despite this, both the Cascade 3000 and the TOTO S350e offer nozzle sterilization.

Wide Spray

The TOTO S350e goes above and beyond, offering four wash modes (front, wide front, rear and soft rear). Wide front cleansing is not found on many bidets, but it’s a useful feature that broadens the water spray for a frontal cleanse that covers greater surface area. The Dignity Solutions Cascade 3000 offers washes more similar to most other seats on the market with standard wash modes (front and rear).

One Button Wash/Dry and User Presets

The one button wash/dry feature on the Dignity Solutions Cascade 3000 initiates a no-frills wash/dry cycle at the touch of a button. Regardless of if you’re choosing the one button wash and dry, or using the wash and dry buttons on their own, the Cascade 3000 will default to pressure, temperature, and position settings used last. The TOTO S550e takes this idea a step further by offering a feature called “user presets”. User presets allow you to program two different sets of favorite wash and dry settings into the remote ahead of time so that when you’re ready to start your customized wash and dry, all you have to do is press the preset button.

Comfort & Convenience Features

Remote Options

The TOTO S350e 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.

Auto Open/Close Lid

The TOTO S350e comes with an impressive auto open/close lid feature that eliminates the need for manually opening the lid. It not only creates quite the wow factor but is also a handy feature to have during flu season or for anyone with physical limitations. The Cascade 3000 by Dignity Solutions doesn’t come with an auto open/close lid, but does offer soft close, so no need to worry about the seat slamming.

Weight Limit

The TOTO S350e 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.

Warranty

Dignity Solutions offers a 4 year full 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 S350e features a 1 year full warranty. Knowing that the Cascade 3000 offers the best warranty on the market makes it a great contender with the best seats on the market.

Final Thoughts

The wide array of features and benefits that come with both the Cascade 3000 by Dignity Solutions and the S350e Washlet by TOTO can make it difficult to decide between the two! The first question you’ll need to consider is your seat style needs and color preferences. The Cascade 3000 comes in both round and elongated styles but is only available in white, whereas the TOTO S350e only comes in round seat styles but is available in both white and beige (for the same seat in an elongated style, check out the S550e). Next, consider what’s on your list of must-have features. Can’t live without wide spray and soft rear washes (in addition to standard front and rear washes), user presets, a nightlight, an auto open/close lid, and a slightly higher weight limit? Then the TOTO S350e may be the best fit for you. On the other hand, if having hygienic stainless steel nozzles, two different remote options, a sittable lid, and a 4 year full warranty are on your list of non-negotiables, you’ll want to go with the Cascade 3000 by Dignity Solutions. Whichever you choose, you’ll be getting a high quality unit that will provide comfort and convenience for years to come.
