kitchen tile

I need to tile a kitchen splashback. Currently the wall is painted with emulsion. The laminate worktop has some skirting at the wall, should I remove this before I tile? If so how to get a good waterproof seal where tile meets worktop? Thanks

Hey guys, Pictured is a tile with a hole in it. We have underfloor heating and I am wondering if I can replace the tile and if so what’s best to use and how’s it best to go about doing it? I’ve never removed or laid a tile before and especially over underfloor heating Any help/advice is...
