You don't have to have everything that looks cool at first glance. If you keep going like this, you'll have to enlarge all the windows because your designs absorb the light, see dark kitchens!
But the toilet is not going in the kitchen... :p Yes, we also want to keep the sinks and the bathtub white. But the niche for the toilet will get yellow subway tiles and the black toilet will simply give a cool contrast.... We think... :Do_O Oh, and the kitchen will be rather bright...
No nonsense: a mix is rather deplorable! No clear line in the tile design nor in the sanitary design - one line you should follow, otherwise it becomes disharmonious. It seems like you want a bit of everything. That is rubbish.
Black toilet and the rest white I find half-hearted. You really have to be careful with that, otherwise it comes across as forced but not well done. Regards
