Can you patch disappointingly destabilized plaster walls? I've just bought a house and whoever owned it previously be horrendous...

I've just bought a house and whoever owned it previously be horrendous at DIY! The units are adjectives fine and quite modern, but they've stripped some tiles bad the walls and left an awful mess. There's not a smooth surface to be see, lumps have fall out etc.. but I'd really like a adjectives splash back. They've even "painted on" some plaster contained by one area!

I've have a suggestion of a stainless steel splash back which I really dont want (reminds me of working kitchens) and we've even considered putting plastic boarding designed for shower interiors on the wall.

Can you not freshly patch up the surface with fresh plaster? And ideally not hold to bring in a proffessional plasterer?
