I bought this for my parents, who had it installed yesterday atop their new Delta Riosa concealed trap toilet bought earlier this year. I had listed a question on Amazon and spoken also to the manufacturer by phone, and both times was told there'd be no problem using the furnished mounting kit and no other parts would be needed. However, my parents say installation was delayed because the professional installer had to buy an adapter because the bidet's water line was larger than the toilet's water line--agh, this confusion is exactly what I'd been trying to avoid! It works. Controls: 1. The control panel needs to be 1.5-2 inches longer--otherwise elderly persons to have to twist around in order to reach the controls. 2. The buttons should be raised, not flat, so that the user can operate the controls by touch. 3. The buttons respond only if they are pressed on the right, not the center of the button. 4. Per another reviewer here, the controls need to be renamed. The term BIDET needs to be used, and DRYER instead of MASSAGER for the airdry function--as is, it's unnecessarily confusing, esp. for guests, etc. 5. Again, per the other reviewer, it should be programmable. My mother, who is Japanese, says the quality isn't comparable to any Japanese bidet she has used, and is esp. difficult for seniors. However, she's keeping it because it would cost her another $100 to have it uninstalled. I am thinking that if I buy them a different model with a programmable remote and raised buttons that are properly centered, I'll have this one relegated to their guest bathroom.

I got the Biobidet LW-1000. It fit great on my Kohler tank toilet. No issues with installation. The manual has everything written in small letters and pictures are small also. Hard to see. Needs improvement. I was expected lots of water and front and back nozzle. Well, I got little amount of water and only one nozzle on the back. The nozzle moves toward the center of the toilet, but not enough to take care of cleaning all female parts. Maybe if there was more water pressure, this could be achieved. The nozzle has the function to rotate sideways a bit to clean a wider area, but the change is very minimal for the low water pressure. Is it worth the money? Not. This company need major review of the design to provide significant more amount of water. I do have tons on water pressure on the toilet water source. This bidet reduces it to below a minimal. In the lack of toilet paper, it will be better than nothing. But like I said before, if I knew that the amount of water would be just a tiny little stream, with no pressure whatsoever, I would not have bought it. Maybe their luxury models are better?

After experiencing our first-ever bidet while vacationing in Hawaii, my husband got this for me for Christmas. I take medication which results in a lot of flatulence and occasionally liquid bowel movements, so I am delighted to have a more civilized way to clean up than toilet paper. The Bio-Bidet Ultimate BB-600 works as expected. I appreciate the warm seat in the winter and the warm water cleaning. I find the air-drying feature to be useless (unless I have 15 minutes to wait to dry). I dislike the attached control panel and would prefer a remote. It is too hard to see the controls, although over time, I have learned where they are by touch. I think the plastic is very flimsy and dislike that the toilet seat cover can no longer be used as a temporary shelf in my very small half-bath. My primary issues with the BB-600 involve the posture in which one must use it. It is necessary to sit forward on the seat and since the back of the seat angles upward, it aims waste at the back of the toilet, rather than straight down into the bowl, where the water is. For someone with the above issues, it results in a mess after each use. Not only is the toilet bowl flecked with waste, the outside of the (still retracted) spray unit also gets splattered. I feel like I'm making a second career out of cleaning the thing. Directions also say to clean the unit (and the toilet) using no cleaning products, only a "damp cloth". NO WAY! I'm an RN and do not clean any of my three bathrooms using a "damp cloth". The basic idea behind the BB-600 is wonderful, but a redesign is indicated to make it a more practical product.

Great bidet, easy to install, convinient remote, connected to the bidet. Easy to clean and working great. Good purchase.

Well-thought-out product and an easy installation if you're a little handy. Works nicely and seems to be made well. Bravo!

Good delivery time. All parts included Very well packaged.

Bidet works great but the seat is uncomfortable. Needs to be a little larger to be more comfortable

We bought the bio-Bidet Ultimage BB-600 Toilet Seat about 2 months ago. We had fun with running the seat with all the options and they worked GREAT! We are so glad we got this. The advertising was spot on and we recommend it to anyone wanting a Bidet.

Since we start using this toilet seat we can tell the difference from too much work of cleaning to all in one time cleaning. We never had this experience. Love the design and feel the better living than before. Thanks for making our family happier life!!

I had Hemorrhoid surgery and suffered greatly. Several years later I needed a similar surgery and bought a BIO600. Being a guy, I procrastinated until it was too late and never installed it. many years later, my Girlfriend was talking about Italy having them and how much she preferred it. The Best Boyfriend ever installed it at her home. Naturally I had to test it out. I was amazed at how well this thing worked. I immediately went to the computer and ordered one for MY house. The installation is easy enough and the kit had ALL parts needed except the pipe dope. Unfortunately in Ralph's world nothing is ever TRULY easy. I turned off the angle stop valve and began unscrewing the original fill hose while checking that it wasn't dripping while I worked on the rest. The top came off fine and I began to position the Bidet hoses. About 6 min. into this, the fill hose began to seep and then the valve completely FAILED! I had to run downstairs to the main to shut it off. After Cleanup I finished and it works MARVELOUSLY! I look back now and wonder why I hadn't installed it WAY before now. Especially considering I have been losing the COVID war on Toilet paper.
