Bidet Toilet Seat Comparison: Bio Bidet BB-2000 vs Bio Bidet Discovery DLS

The Bio Bidet BB-2000 and the Discovery DLS are Bio Bidet’s two flagship bidet seats. Both seats provide quality cleansing and are some of the best bidet seats money can buy. While the BB-2000 and Discovery DLS are both packed with high end features and unique functionalities, there are some key differences that set them apart.  Let’s break down the two models and compare them side by side to see how they stack up so you can decide which Bio Bidet is the best bidet seat for you 


Between the BB-2000 and the Discovery DLS it is clear which bidet focuses more on contemporary style and aesthetic. The Bio Bidet DLS boasts a low profile design standing at 4.7 inches at its peak, having one of the sleekest silhouettes out in the bidet market.  Additionally, its design is more minimalistic without any color accents on the body.  The Bio Bidet BB-2000, on the other hand, is slightly wider and taller in the rear.  It sports a silver accent that runs across its rear portion. The BB-2000 has a robust look that’s more similar to other bidet seats on the market. If the contemporary aesthetic is your thing then this may be the deciding factor between the two.

Spray Capability 

Strong spray pressure is where the Bio Bidet BB-2000 made its name. It undoubtedly still has some of the strongest spray pressure out on the bidet seat market. Additionally, the Bio Bidet BB-2000 has a true enema function - a powerful, narrow spray which helps alleviate constipation. Of course spray pressure is fully adjustable, so there is no need to worry about its spray functions being too powerful.

The DLS Discovery has above average spray pressure compared to the market.  It delivers a robust spray that is capable of effective cleansing and is not weak by any standard, but it does lack an enema function.  We estimate its rear wash to have about 10% less pressure than the BB-2000 when set to max.  The DLS oscillates its nozzle in the rear wash function by default, a nice shortcut feature for users that prefer it.  

Water Heating Type

The Bio Bidet 2000 utilizes a hybrid heating system. This means that the seat’s heating system functions by having a small reservoir of warm water preheated. During a wash, the BB-2000 will draw from this reservoir while also continuing to heat the water for an endless supply.  This assures that you never feel a spurt of cold water. 

The Bio Bidet DLS, on the other hand, uses a tankless water heater. This means that there’s no internal reservoir with preheated water. This absence of a reservoir allows the seat to be a bit sleeker, as it heats the water on-demand during a wash. This method is the most energy efficient because water is not preheated until you begin washing.

Unique Features

Bio Bidet BB-2000

Enema Function - Although there are a handful of enema functions out in the market for bidet seats, none can really compare to the BB-2000’s enema spray (other than the BB-1000). The main reason here is because of how powerful and narrow the spray is on this function. The spray pressure really aids the narrow shape to penetrate and relieve constipation or cleanse the rectal area.

Powerful Pump- Powerful spray is the definition of the BB2000. The Bio Bidet’s pump puts out the most amount of water on the bidet market. Not to fret though, this power is fully adjustable as well as aerated in order to have a very comfortable, yet thorough wash.

Bio Bidet DLS:

Auto Lid - The auto lid is a feature limited to only a handful of bidets on the market, and the Bio Bidet DLS is one of the few to boast such technology. This fully automatic lid senses when you approach and lifts the lid and/or seat automatically. For those who do not wish for the seat and lid to open every time one passes by the toilet, the auto function can be turned off and lifting/lowering can be controlled via remote instead.

UV Nozzle Sterilization- The Bio Bidet DLS sports a UV nozzle sterilization system which helps eliminate bacteria and other virals. A very high tech and truly rare feature not found on many bidet seats.

The Bio Bidet DLS’s remote control is a dual sided wireless remote displaying all basic functionality on the front side while all fine tuning resides on the rear side.The DLS remote is a slim, contemporary, and easy to use remote displaying all functions in text for clear distinguishability between functions. 

Differences in Nozzle Construction

The Bio Bidet DLS nozzle is fully constructed of stainless steel for simple cleansing. Additionally, the Bio Bidet DLS’s nozzle is fully sterilized by the UV light system, stopping bacteria from festering on the nozzle.

The Bio Bidet BB-2000’s nozzle is constructed of stainless steel with a plastic removable tip. This plastic tip is designed for easy replacement in the case of any issues with the spray of the unit or simply if you question the integrity of it. The Bio Bidet also uses a self-cleaning, single nozzle system with different sections for its various wash functions.
