That is a hard one with those tiles. I would have to think if you did a white, it would kind of work with the colour of your tiles. At the end of the day, they do need to be replaces, but as you said, due to budgeting reasons, you cannot, I can pass on this photo of a nice bathroom with those tiles for you though for inspiration... : )

I really hate black and enjoy natural bathrooms. You can add colour in various ways, including towels, accessories. And change the accents as you get sick of them. I've never got over black baths that existed in my childhood (and looked dated then) - too dark for most spaces and show up soap, powder etc far more than natural tones.

Both are right for different houses, no right or wrong here

Hi there, I would be thinking to go for white cabinets and walls,with white appliances that you plan on Keeping or can change to stainless, your choice of benchtop. as this picture shows the timber door frames etc will then fit, White cream and timber should blend in with the floor tiles, maybe even the blinds will look ok, photos help
