1. Tile can be done over clean well bonded tile only 2. You should only use a premixed adhesive in a non wet area only. Any areas such as a bath tub or shower enclosure a cement based thin set ( thin sets are all cement based) Mastics or premixed adhesive are water based and will dissolve or lose their bond over time in a wet area.Although there are some premixed thin sets but I don t trust them and have never used them since its so much cheaper to use and mix thin set. 3.Standard grout is cement based and IS NOT water proof at all! Only your epoxy grouts are.. 4 Tubs or shower base must be in before tile. Stools optional unless your doing floors which you only said walls. The exception is if your doing behind the stool as in a wainscot. 5.Putting water in a tub will not level it. Follow manufactures suggestions on this since they vary from maker to maker and styles. Water in a tub is recommended only when caulking the tile edge at the tub. Let caulking dry and let water out. Any questions you can e mail me through me avatar and check my qualifications there. GL
[1] Yes you can tile over the existing tiles, What you need to do first? Is to rough up with rough sandpaper on the existing tiles to give a bite for the new tiles to hold on. [2] It is better to have ready mix, because it will have every things in it [3] Most grout are waterproof and also you can get differ colour grouts to match your bathroom. [4] Put in your new suit first, then tiles on top of your existing tiles, and grouts it as well. [5] fill your bath first, then seal it, so it will have the weight of the bath and water in it and it wont break the seal and lest chance of a leak.
