When installing over top of old ceramic/porcelain be aware that you will most likely have to "sink" the old tiles in cement to do this. That means grinding down the tiles a little (rough up the surface) then the self leveling cement is poured and allowed to dry. The new floor is then laid over top. Vinyl is notorious for requiring EXTREMELY flat surface. A ceramic tile rarely has this requirement (grout lines and "high spots" around tile corners give problems). A glue in place tile is also going to have the same problems and the same solution = sinking the tiles in cement. This adds extra costs to the floor. A rigid floor like a cork floating floor can handle a bit more floor deflection than vinyl or laminate planks. If labour in your area is relatively cheap...you could probably have the tile removed and the sanding of the mortar done for the same price as coating in concrete. You will also have the luxury of being able to lay any floor you want once it is done AND you don't have to worry about increasing the floor height. It is possible to sink the ceramic in cement...but is it the most cost effective option? Maybe not.

Nice reno :) Few things imo... don't think you need any artwork next to the hexagonal mirror, it could get too busy, if you're after a more balanced look I would move the chest of drawers & mirror to the left more centered on the wall, then relocate the white rack to the other side near the door in place of where the bin is now, not sure the bin should be a feature and be the first thing you see when entering the room, if the drawers have moved that far corner may now be better for the bin... yes the wall above the bed definitely needs some artwork, which I think should be as wide as or wider than the bed, if a large artwork is too costly maybe three squares alongside each other to create the width, stick with the style of the room (can't quite work it out) and pick colours to complement the more permanent fixtures like the blinds rather than colours from the bed linen etc which will change

Hey! I think it'd be good if you used the 'Find Professionals' tag to find a bathroom renovation specialist who could help you with what you need.
