Let customers speak for us
Great bidets
I really liked them, they wash well
I will never be without one.
I installed a Discovery DLS in my master bath up north, loved it so much, I ordered another one for my master bath down south. Love the heated seat, thenightlight, the pre-flush, what a phenomenal product.
Bio Bidet Amazing
I bought this bidet several months ago and it has been the best purchase. It took me months to pull the trigger on a a bidet because you want to pick the best one. This has everything I wanted heated seat, air dry, temperature controlled water. I’d recommend this to anyone who is looking for a top notch bidet. Highly recommended. It came with all the pieces and nozzles so installation took literally 10 minutes. Highly recommended again.
Excellent Product!
We absolutely love all of the features this smart toilet has. It’s become the star of our recently renovated main bathroom. This was a bit of a splurge for us, and so far, we have no regrets. We purchased it about 2 years ago in anticipation of the bathroom reno, and finally installed it last month, so we’re hoping all the amazing bells and whistles that we love so much about it continue to work for a long time to come!

Excellent product!
I bought this a month ago and couldn’t be happier with the purchase. The simplicity of the design and install made it a breeze. This was purchased because a friend had one and recommended it. Solid product and detailed instructions.
Luxury modern bidet toilet
Bio Bidet Discovery DLX bidet toilet is an amazing product. This bidet toilet definitely elevates bathroom experience. It is packed with variety of features, the design is modern and sleek. Motorized seat and lid are great. The spray pressure is perfect and warm air dryer feature is amazing. This toilet also has a blue LED nightlight which makes it easy to find it in the dark without turning all the lights on. It also has UV sterilization feature. I cannot say enough great things about this product, it is truly luxurious.
Super clean
Wow! Thank you Influenster! In my head I was going to receive the toilet seat bidet. I got a phone call for a special delivery of 130lbs! It did take me a second to find someone to get electricity and set up the toilet. The toilet!! It’s amazing! It seems to be very well built. Some of the highlights need to include the heated sensor seat and the front kick button. It controls seat raising and lowering and flushing. My favorite is that it will flush itself once you stand up. The bowl has a water stream from the right side that gives the bowl a little rinse when you get started. I feel like it keeps the bowl cleaner. The remote control is very easy to use. There are so many settings that control temperature and water pressure. The dryer also has temperature settings. It would be great if there were dryer speed settings. The only issue I can see is that directly behind the fan and nozzle it seems to catch debris. Thanks for the great opportunity!
Satisfied customer
A number of years ago we purchased our first Bio-Bidet and thoroughly enjoyed it. We have just upgraded to this new seat and expect to get the same dependable service from this model. We recommend this brand!
Installation Was SUPER easy!!!
I never thought I'd be writing a love letter to a bidet, but here we are... This magical contraption has turned my bathroom into a cozy spa retreat. The seat warmer is like a toasty hug for your behind, and the heated water feels like a warm sponge bath from a very considerate robot. The self-cleaning nozzle is a game changer! No more weird acrobatics trying to scrub the un-scrubbable. And can we talk about the large wireless remote?! It's like I'm piloting a spaceship to the cleanest region of the universe. I don't know why bidet remotes need to be so large, but I'm not complaining! It's the TV remote I never knew I needed for my bathroom adventures.... (wait...TV... in my bathroom?! I would have never considered it before, but now that I enjoy sitting on the throne so much I think that would be a wonderful addition!) Now let me brag for a moment - I managed to install this technological marvel in about 20 minutes from unboxing to first squirt. I'm no plumber, but the instructions were so clear that even my goldfish could probably have done it. All the necessary parts were included, and it turns out, I must have a secret talent for bidet assembly/installation. In conclusion, my bathroom is now a high-tech sanctuary, and I am the reining bidet champion of my household. Bow down to the throne of cleanliness!
BB-1000 Sweet Features! My first bidet.
I was skeptical. I'd never even seen a bidet. But after a couple surgeries my doctor and wife suggested we get one for me. I just didn't really know what a bidet really did. I thought they were for women. Man, was I wrong and living in the stone age! So, I ordered one from BioBidet. After my last surgery I still couldn't use a toilet, but the bidet and a new toilet arrived. About 2 months later I was beginning to get back on my feet...so I called my plumber and had him install. Man, talk about my surprise after reading the manual, adjusting some settings from the remote. It's like heaven. The seat is warm instantly. Rinsing water is warm too...and adjustable! You can have the Nozzle stationary or have it move forward and reverse. I've got a little issue with the remote not always working..but hoping customer support will swap it out for me. I'm considering a second bidet for the other bathroom. Why not!
Simple and effective
This bidet attachment was easy to install and works very well.
Great features, fun, and keeps you fresh
The product is very futuristic and modern, love it!
Fantastic upgrade to any bathroom in your home
Fantastic upgrade to our guest bath, very happy with the installation process and the sleekness of the design. Our guests have been impressed with the features, after a month of use, we are ready to add more of this model to our home.
Love it!
Love this toilet! Looks so good and flushes nice! Would recommend anyone looking for a wall hung toilet.
