Pros & Cons

– For 200, I can get Bidet.
– Easy mount – somewhat
– Water get warmed real quick.
– Pressure of the water is really good

– Seat is angled I don’t know why but it makes uncomfortable to seat
– The water tank for warm water is so small, it cannot even run full cycle with same temperature
– It use abnormal size of hose (one for faucet) meaning you need two converter, one for toilet infeed(1/4) to 3 way(5/8 I believe, it comes with 3 way), than you need to convert back from 3 way which is 5/8 to 1/4 the normal toilet size. However its quite hard to find the right size if you don’t know it. It would be ideal to sell with 2 converters

Bio Bidet Discovery DLS Bidet toilet seat review


The Discovery DLS is just 4.7” high in the rear. This is by far Bio Bidet’s slimmest bidet seat and is almost as low as the class leading TOTO S550e Washlet (4.5”). Compared to their best selling Bio Bidet BB-2000, which is almost 6” tall in the rear, the DLS has a much sleeker silhouette that gives it a more modern aesthetic.

LED indicator

It ha cool white LED nightlight that shines into the bowl. LED nightlights that shine into the bowl not only provide the wow factor for guests, but are also more functional and allow users to use the toilet at night without needing to turn on their bathroom lights.

UV Sterilization 

A nice luxury touch that sets the Discovery DLS apart is the use of UV technology to sterilize the nozzle. After each wash cycle, the DLS will use an internal UV light to help sterilize the nozzle. This is in addition to the nozzle’s self-cleaning function that uses water like other bidet seats. UV sterilization is a nice added benefit for users that are keen on keeping the nozzle surface extra hygienic.

Warmed seat function

The warmed toilet seat is wonderful during the colder months of the year and can be adjusted over different settings to find a comfortable temperature.  The Discovery’s enhanced multi-speed (three speeds) air dryer is the fastest, most efficient dryer Bio Bidet has produced and boasts increased drying times when compared to the previous generation Bio Bidet BB 2000.


The remote control itself has a nice, minimalist aesthetic to it and the button positions are well thought out. The front face features just 5 easy to read buttons for the basic functions STOP / FRONT / REAR / DRY / AUTO. All other adjustments will be found on the backside while the lid and seat lift/close buttons are along the top edge for easy access. 

Motorized Opening/Closing Seat and Lid

The DLS features a motorized seat and lid that open and close at the press of a button. The motorized action is impressively smooth so the lid and seat do not slam into each other. This feature is perfect for users wanting a truly hands free experience when using the toilet – no touching of the seat or lid required.

Bio Bidet Discovery DLS Bidet toilet seat Installation

-The seat attaches to the toilet by sliding onto a mount that is bolted to the usual toilet seat mount holes. It then locks into place.
-The electrical cord is located in the middle of the back of the seat, making it equally as usable with a left-sided or right-sided electrical outlet. It measures about 46″ and is a 3-prong grounded plug.
-No plumber’s tape is included, but it is necessary for installation to prevent leaks. It is a 50-cent item that should just be included with the box.

Great Design and Features in a Well Priced Bidet Seat

The Discovery DLS is a well designed, feature-rich, luxury bidet seat that will meet the expectations of the most discriminating individual. I was looking for a well designed but not over-engineered product that the manufacturer would stand behind, not just next year, but for the foreseeable future (5-yr parts/labor warranty).

The seat has a low profile design and well engineered installation and setup. Installation was relatively straightforward, though there is room for improvement in the installation instructions (which side of the metal brackets face upwards) and some basic FYI’s related to standard cord length (4′), cord side (RH side when viewing from the front), power requirement 120vac GFCI-protected outlet supporting ~8.75 amps (1050 watts/120vac). That said, I found a YouTube product review video from an installation professional that stepped through the install (simply Google “Discovery DLS Installation”).

Finally, the price point is very reasonable given the luxury features/function, design, and warranty.

TOTO Washlet S550e

As the flagship model from TOTO, decades of engineering have gone into the S550e design and it shows. At just 5” tall at its tallest point in the rear, the TOTO S550e is the thinnest electronic bidet toilet seat in the world. This slim design adds greatly to the modern look of this seat, when compared to the more bulky design of other seats in this list. Having all the cordage on the same side of the seat helps too. Most other bidet seats have the electric cord on one side of the seat, with the water hookup on the opposite side. But with the TOTO S550e – both the electric cord and water hose are on the same side which makes things look a bit more tidy.

If you’re looking for something sleek and modern to match the look of your high-end bathroom, look no further than the TOTO Washlet S550e. Simply beautiful in its design, this bidet seat actually comes in your choice of two lid styles – contemporary and classic. The contemporary version has a minimalist vibe – with a clean, top lid which fully covers the seat underneath. The classic version has contoured edges as you look around the corners of the lid, adding a touch of cosmetic refinement in its design. With these two lid styles you can really choose a seat which looks best to you.

Brondell Swash DS725

What makes this seat of extra special value, is the fact that it still comes with wireless remote control! Most seats in the sub-$400 range come with the controls attached to the side of the seat. With attached control panels you’ll find some of the buttons way in the back. This results in having to twist your torso around and looking behind you while seated in a forward-facing position to access some of the controls. Not fun! But with the handy remote control of the Brondell Swash DS725, you can simply hold the remote in front of you. A wall mounting kit also comes included so you can hang the remote back on the wall when you’re finished.

Selling at a price point of $300 – $400, the Brondell Swash DS725 is the best “bang-for-buck” electronic bidet seat you can buy. Despite its very reasonable pricing, this seat still comes with all the features you would expect in modern bidet toilet seat such as posterior wash, feminine wash, adjustable water temperature, adjustable water pressure, and adjustable spray position. The Swash DS725 even comes with some advanced features too, for example – its stainless steel nozzle, air deodorization system and in-bowl night light which illuminates the toilet bowl with a cool-blue glow.
