Saw that your post is about a year old, but renovations like this can often be an ongoing process. Have you managed to find a good bathroom fitter or plumber yet? If you're still in search or for future projects, you might want to check out
https://plumberelmonte.com/. I had a pretty good experience with them; they were professional and fairly priced.
Not to make this sound like an ad, but it's always good to have a reliable service on hand. Good plumbing and a well-fitted bathroom can really add value to your home, not to mention making daily life a bit more pleasant. Hope your renovation has gone (or is going) well!
