Detailed Comparison

Look & Feel

The Bio Bidet dib-850 features a polished silhouette along with a sleek, low-profile design that eliminates unnecessary bulkiness for a streamlined overall look. The Cascade 3000 by Dignity Solutions has a classic look with a contoured lid that adds understated elegance to any bathroom. One unique aspect to the Cascade 3000’s design is that it can fit on most one and two piece toilets, including many French Curve toilets that are often unable to accommodate bidet seats. Like most other bidet seats, the dib-850 won’t fit on French curve toilets.

Wash & Dry Features


Stainless steel has long been considered the most hygienic and durable material for bidet nozzles, and the Dignity Solutions Cascade 3000’s single, 2-in-1 nozzle is crafted entirely from stainless steel. In comparison, the Bio Bidet dib-850 has a single, 3-in-1 nozzle featuring a wand constructed from stainless steel and nozzle tip made out of plastic. The numbers “2-in-1” versus “3-in-1” simply refer to the number of nozzle spouts at the end of the wand. The Cascade 3000 has two nozzle spouts, one for the front wash and one for the rear wash, while the dib-850 has three nozzle spouts, one for the front wash, one for the rear wash, and one for the enema wash.

Nozzle Sterilization

Nozzle sterilization is a specialty feature offered by some bidet seats, including the Dignity Solutions Cascade 3000. The 3000’s nozzle sterilization system relies on a silver nano solution that coats the interior tubing of the unit as well as the inside of the nozzles. This coating uses silver’s natural antibacterial qualities to ensure that the bidet’s interior components stay sterile and clean, thus ensuring that the wash water stays optimally clean as well. The Bio Bidet dib-850 doesn’t come with nozzle sterilization technology.

Water Flow

A higher water flow rate often corresponds with a more efficient and effective wash, so it’s a relevant detail to keep in mind when purchasing a seat. That said, there isn’t a huge difference between the Dignity Solutions Cascade 3000 and the Bio Bidet dib-850 when it comes to flow rate. The Cascade 3000 has a flow rate of 0.18 gallons per minute and the dib-850 comes in a close second at 0.16 gallons per minute. However, due to the design of the the nozzle, the Cascade 3000’s wash offers drastically better water pressure.

Enema Wash

An enema wash function is a must-have feature for individuals dealing with chronic constipation. The Bio Bidet dib-850 features an enema wash that shoots a powerful stream of water into the rectum to help loosen stool and stimulate bowel movements. The Cascade 3000 bidet seat doesn’t come with an enema function.

Pulse Wash

The Bio Bidet dib-850 offers an option called “pulse wash”, which varies the pressure of the water stream to create a soothing massage that relaxes sensitive areas and encourages the bowels. The Dignity Solutions Cascade 3000 doesn’t offer pulse washing.

Wide Spray Option

While the Dignity Solutions Cascade 3000 offers a single, standard spray width, the Bio Bidet dib-850 offers both a standard spray width and a wide spray width. Wide spray is handy for times when you need increased wash coverage to get clean, and it can cut down on the amount of body repositioning required for a thorough cleanse.  It is important to note that as the width increases, the water flow does not, so the pressure gets weaker as the spray widens.

Comfort & Convenience Features

Control Options

Operating the Dignity Solutions Cascade 3000 is easy thanks to the wireless remote control that comes in two different sizes and styles: a larger remote or a standard size remote with a display screen. The Bio Bidet dib-850 comes with a standard size remote control featuring flat buttons (no display screen).

User Presets

User presets, which come with the Bio Bidet dib-850, are a handy feature that allow users to program their favorite settings into the remote for a completely customized wash cycle at the press of a single button. The Cascade 3000 by Dignity Solutions doesn’t have customizable presets, but does save the last settings entered for furture washes. It also comes with a one button wash and dry feature that initiates a standard wash and dry cycle at the touch of a button.

Weight Limit

Both the Dignity Solutions Cascade 3000 and the Bio Bidet dib-850 have a generous weight limit, but the dib-850 comes out ahead in this category with its 400 lb weight limit compared to the Cascade 3000’s 350 lb weight limit.


A good warranty can provide you with peace of mind regarding your investment. The Bio Bidet dib-850 comes with a 3 year full warranty and the Dignity Solutions Cascade 3000 comes with a 4 year full warranty. The main difference between the two companies is that Bio Bidet offers the option of upgrading to a 6 year full warranty whereas Dignity Solutions doesn’t offer warranty extensions at this time.

Final Thoughts

Both the Bio Bidet dib-850 and the Dignity Solutions have a lot to offer and provide all the features necessary for a comfortable, high-quality cleansing experience. The best way to decide between the two is to evaluate what you consider to be must-have features given your needs and preferences. If you want a wide spray option, pulse washing, an enema wash, user presets, an extendable warranty, or a higher weight limit, the Bio Bidet dib-850 is the unit for you. On the other hand, if you’re looking for a bidet with 100% stainless steel wand and nozzles, nozzle sterilization technology, slightly higher water flow, an easy to use remote, better water pressure and a choice between remote styles and sizes, the Cascade 3000 by Dignity Solutions will meet your needs best.
