I actually find the floor in the bathroom quite chic, I can live with that. If I get bored (without high priority) I might lay vinyl over it, if not it's OK. I think I'll paint the tiles, yes. Some light color. We'll see, there's inspiration online. Does anyone have tips on a brand for tile paint that lasts well?
Can I also paint the sink? It's curry brown too, it's really nasty. :D
Oh, about the kitchen I expressed myself poorly - I actually want to put the washing machine on that other wall (in front of the window), and the dryer, and just lay hoses over there very unprofessionally if that's possible. But I don't know if/how that works with the washing machine's wastewater, there has to be a slope.
Alternatively, there are still 2 washbasins in the other bathroom, it would also be conceivable to remove both old sinks and put in a new sink (then I wouldn't have to paint them either), and put the washing machine next to it.
