Sorry, for me that is a recipe for disaster. My flooring guys would refuse the job. Elevation change and tripping hazard not worth it. I get wanting to save money and less mess, and sometimes taking the easy and cheap road now will cost more down the road.
Unfortunately, I would not do this, I would take up the vinyl floor first. Taking a short cut in the beginning could end up taking much longer later on and ceramic tile is not cheap. In addition, I would imagine that you would get little cracks in the grout over time.
If the existing vinyl floor was installed over concrete and is glued down firmly, you should be able to tile right over it without any problem. Scrub the floor first to remove any dirt and grease then apply a bed of thin-set mortar and tile.
If the vinyl was applied over a wood subfloor, you should install 1/2” thick cement backer board on top of it first, using corrosion resistant screws driven into the floor joists. Another option to backer board on wood floors is one of the new polyethylene membranes such as Schluter®-DITRA. At only 1/8” thick, it can shave 3/8” off the finished thickness of your floor if height is a problem.
You can also tile directly over an existing tile floor as long as it is sound. As with vinyl, clean it first so the mortar will adhere well to the old tile.
I don't advise it and I wouldn't do it. BUT my daughter had it done in her master bath. I was skeptical. Going on five years and still holding up. Thinset and ceramic tile directly over vinyl. Guess it can be done.
From what I've read, you can, but some experts don't recommend it especially if it's vinyl tile.
Yes but you have to put a backer board down first
