Stick on tiles?

[Zippedydoobaah]

Moved recently and tiles in bathroom and kitchen are a very boring white. I'm not in a position to change them yet, keep seeing ads for stick on tiles on social media. Are they any good? Hard-wearing etc?

I'd wait until you can afford to change them for something that is more your style.
Boring white isn't bad OP - it's a blank canvas. Dress the room in other ways for now. Rugs? Plants? Pictures? Chalk Board? bring some texture and colour to the spaces

We had some stickers to liven up the tiles in one room that were quite fine - from b&q

I used them to spruce up the bath panel and sink backsplash in a bathroom. They were quite fiddly especially if you’re a perfectionist. Fortunately once finished I couldn’t see the imperfections (that might have more to do with the fact that I am supposed to wear glasses but rarely wear them!) The ones I used showed the texture of the awful mosaic behind them around the sink but was fine on the bath panel. A bit of lifting at the edges, so I might hesitate to use them in a very wet area but nothing major, they coped well with steam and if I was doing again I think sealant at the edges would protect against this as it was hard to stick them down perfectly in the corners. Overall I was pretty happy with them, but they were nearing the end of their life due to the lifting about a year in, but at that point I was buying a new flat anyway

A friend has recently put them in her downstairs loo. They look well and seem to be holding up so far. She bought them online from Temu I think. Long term she plans to tile but is saving to do so.
