Help Me Pick the Right Product! Too Many to Choose From!

Hey! I’m delighted to have found this sub! My biggest dream has always been owning a bidet toilet. Now is the time, but I’m lost among so many choices.

I have gas central heating and as part of bathroom renovation, I will get the hot water plumbed into the bathroom that’s currently working with an instant electric shower.

Is it better to go with an electric water heating system for the toilet or the ones that already take the hot water input?

I found [this one](https://www.bathhead.co.uk/product/bianco-wall-hung-smart-toilet-with-bidet-wash-function-heated-seat-dryer/) to be a reasonable price. Is it a problem if it’s floating rather than sitting on the floor?

P. S. I’m in Europe, and Toto doesn’t seem to be an option here.
