Looking for opinions ...
The current vanity top is 4" white tiles, backsplash of same, bullnose at front. Looking at the sink cutout from underneath, it seems like the tiles are set in a mortar bed (wire mesh, and about an inch of mortar, over ply).
Googling, it seems that removing a mortar bed is a PITA, and tiling over tile is an option. Further, since I tiled the floor, the counter is a little low - so the added height would be a plus.
I'm thinking to remove the bullnose (so I don't end up adding depth) and backsplash, and tile upwards from there.
Does this sound reasonable? Should I thinset in a layer of hardi, then tile, or just tile? Sand down the tiles first, or just latex-modified thinset?
TIA, JSH
Bonus question: the current sink is a drop-in, but I'd like to use an above-counter / vessel style sink, so I'd need to fill in some of the cutout to support the tile underneath the vessel. Ideas?
