Hi all - looking for some expert advice. I need to put a low-base washbasin in my laundry area. I will place the sink in the area that currently doesn't have tiles (see pics). Could you please advise if I should water proof this area and then put tiles on it or it is ok to just put tiles directly? Secondly, tiles or splash back, which one is a better option? Also any advice on the tools and materials to be used for putting tiles on a wall will be appreciated?

Thanks
