Getting the tiles off the walls, intact might be an issue. You need to redo the supply plumbing to the new fixture. If you can open the wall from behind you should be able to replumb it without doing damage to the tile wall. You might be able to take the replacement tile from behind the toilet tank and fill it in with a close substitute. This is not a typical install. Very few people attempt it due to the machinations involved. The ease if the install, will depend on the wall's construction. Ron

Hey breezy! You and me both! LOL I had a different rainhead when we remodeled Mbath at previous house. It was also large and I loved it! Though when I washed my hair, I sometimes used DH's. ( I have very thick hair) We are probably still a month away of being in. The latests setback was the stair color. I told the GC I wanted kind of pecan colored to match my floor. Some how I ended up with BURGANDY! So, they were stripped and sanded and now 2 1/2 weeks later since starting the staining, they are the correct color. Sometimes I just want to pull my hair out! Good luck on your faucet choices! Bridge

Another source for ideas is Houzz. I just went to the site's [bathroom section[(https://www.houzz.com/photos/bathroom-ideas-phbr0-bp~t_712) and put "wall mount tub faucet" in the search box at the top. The result was many, many pictures, both contemporary and traditional, of wall-mount tub fillers, most without a diverter. While the fixture manufacturer is not always identified, it often is. You'll see that many have a narrow section built out from a wall (and often under a window) to mount the faucet. Talk with your plumber about what if doable. You can also select "Products" instead of "photos" in the drop-down section to the right of the search box. That will give you some more examples (though many will be for sinks rather than tubs). Here is one example. [Modern Bathroom design[(https://www.houzz.com/photos/modern-bathroom-ideas-phbr1-bp~t_712~s_2105) by San Francisco Architect At-Six Architecture

I wasn't being sarcastic on my post. I was just pointing out that there are a lot of people in the trades that dispense erroneous information. To me, a "professional" is someone who continues their education in their field. They become more knowledgeable and capable the longer they practice. There are too many folks out there today that call themselves a "professional" this or a "master" that, and too many of them seem to have received their educations from watching HGTV. Just keep asking questions, and if lazypup answers, ask no more. I've never seen her give bad advice. Mongo
