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.
Beyond its forward thinking design, the Bio Bidet Discovery DLS also features a 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.

Bio Bidet designed the DLS remote control with beauty and simplicity in mind. 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. The remote control itself has a nice, minimalist aesthetic to it and the button positions are well thought out.

Features and Functions

The Bio Bidet Discovery DLS is targeting the top end of the bidet toilet seat market and it certainly has the full gamut of luxury features one would expect. It is powered by an energy efficient tankless water heating system and its spray pressure is solid, above average - more than adequate for effective cleansing. The DLS’s default wash setting includes nozzle oscillation. If you prefer a stationary nozzle, simply press the wash button a second time.

Its warm air dryer and heated seat are adjustable, comfortable to use and provide consistent heating temperatures. The Discovery DLS uses a single, stainless steel wash nozzle with different sections for the different wash functions. We found the stream nicely aerated and comfortable in both front and rear wash cycles.

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. One note is that the DLS proximity sensor is disabled by default so the lid will not automatically open upon approach. To activate the sensor, press Nozzle Clean + Dynamic Stream and hold for 3-5 seconds. The seat and lid will automatically close after being idle for 2 minutes.

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.

5 Year Warranty – Bio Bidet is so confident in the quality of the Discovery DLS that they’re offering an industry leading 5 year warranty. The warranty covers 100% of parts and labor costs for a full 5 years from the date of purchase without needing to purchase an extended warranty.

A Decent Product

The lid stays open too long after leaving the toilet.
The heater is very close to one cheek and burns if running too long. also, I wish they could have put the air dryer above or below the cleaner, as it would be more effective and efficient. After 4 minutes, which is the shutoff time, I am sufficiently dry.
As for increasing the water pressure while cleaning, it sounds like a gattling gun, with the water pressure varying I guess.
Also, when initiating the clean phase, I notice that initially, there is a second or two of cold water, but then after that it is warm water from there. It would be nice if they would flush the water for a second or two, so that it starts out warm.
I wish there were user 1 and user 2 memory settings on the remote.
For the Auto function, I wish there was a way to re-program it. It will run the water cleaner, and then dry, but the fan speed is only on low. I wish the fan speed for the Auto function could be modified.
Lastly, I wish the occupancy sensor could be triggered to turn on/off the heated seat. The heated seat also takes quite a while to warm up; about a minute.
Overall, I would give it a 8/10.

Best Bidet

I replaced a older bidet with the BB-2000 which was great. I then decided to get a second for my other bathroom and decided on the BB Discovery DLS. I was worried about the low pressure as some users posted but that has not been an issue at all. This is a great bidet and I wouldn't look at anything else.

Best Bidet out there - 5 year warranty and YES - you can Mute the Sound!

I did a lot of research. The reasons that make this Bidet stand out from the rest are the UV sanitizing light, the Tankless water heater and the 5 year warranty. All of the many other options are great if not incredible.... and YES... if you Hold the 'Night Light' bottom for about 3 seconds... then the notification sounds become silent. Other people are saying they can't shut off the sounds... well... they are wrong. The size of this device is about the slimmest on the market... and the seat size appears to be very adaptable to most toilets on the market. I cannot say enough good things about the Bio Bidet DLS. If you try to save a few dollars... and buy something else.... you will have lots of opportunities to think about your decision :)

An outstanding experience!

I decided to purchase the Bio Bidet Discovery DLS from Bidet King after considerable research of bidets and vendors. I placed my order and received the carefully packaged bidet in 3 days. I looked over the enclosed materials detailing the installation and operation of the DLS and also reviewed the well done Bidet King YouTube video about installing this particular item The printed materials from Bio Bidet are excellent, very thorough and easy to understand with superb graphics. Likewise, the Bidet King YouTube video was outstanding.
Yesterday, my son-in-law also reviewed the materials mentioned above and installed the DLS unit in less than 30 minutes. Since that time, my wife and I have both found the DLS to be an outstanding product. It performs it's tasks exactly as described in all of the printed materials and videos. It it does so quietly, efficiently and quickly.
We are thrilled with our purchase of the Bio Bidet Discovery DLS through Bidet King. I had spoken with Vincent at Bidet King when I had some questions about various Bio Bidet models and he was very professional and very knowledgeable about all of the features of the various products. I highly recommend the Bio Bidet products and the fine folks at Bidet King if you are in the market for a quality product and experience.

Best in Class

I took a chance and spent a bit more for this model. The main selling points were: decent water pressure, promised an effective dryer, had solid build construction (I'm not a lid-sitter but why spend $100s on something a guest might break if they happen to?) and, frankly, with the recessed lid it just looks good. In terms of features, it is punching well above its weight class.

BidetKing shipped the order within 24 hours and it arrived in three days. I had it installed in 30 minutes. To be honest, I was a bit disappointed with it initially. The pressure was not as strong as I'd hoped (my only point of comparison was a cold water manual attachment that was basically a fire hose). I had nothing to compare the dryer to but if this is a good one, the dry on lower-end models must be feeble. Aesthetically, it's great. It is well-designed and everything works smoothly. I did not want to return it for something cheap and clunky-looking so I decided to give it a few days and I'm glad I did.

I guess any bidet is going to have a learning curve - mainly the settings you need and how you'll want to position yourself on the seat to optimize the effectiveness of various functions. After a week of experimenting, I'm happy with it. The stream could be stronger but used properly it will get the job done in one cycle. I noticed that a lot of warm air escapes from between your legs during the dry cycle so closing them and basically trapping the warm air in the bowl helps but it still will not get you completely dry in one cycle... but it's close enough. The seat has features I don't really need. Some can be disabled, which I did for the proximity sensor because it worked too well in the tight quarters of the room. But probably better to have features you don't need/use than spend a small fortune on a toilet seat and really wish it was also a nightlight or whatever.

In the end, I highly recommend this seat and think it's well worth spending a little more for if you're already making the investment. It's not perfect but rounds up to 5 stars.
