The Bidet Attachment connect to the bolt holes between the toilet bowl and toilet seat of your toilet. These Bidets do not come with a seat or lid and use your existing seat and lid. For the most part they will only fit two-piece toilets.

Some of the Bidet Attachments are cold water only and others connect to your hot water supply under the bathroom sink like the Bio Bidet BB-250.

 As with all Bidets that I sell, they all come with the parts necessary to install them.

I have discovered that a lot of people don't adapt well to the cold water Bidets, including myself but some people are okay with it. The warm water is very therapeutic and soothing. If you live in a very warm climate and your cold-water temperature is lukewarm to the touch, then you should be okay, unless you like all the extras that Electric Bidet Toilet Seats have to offer.

You are always welcome to call us toll free at 866-928-8497 or here is the email link for the Contact US form and we will be very happy to help you. As far as I know I am the only person that has personally tried most of the units on the market and all the ones I sell, so I understand very well how they all work and help you with your choice.
