breezer said:painting tiles is never a good option, no matter how its done.
(it actualy creates more work in the long run, and costs more £)
as you yourself said the hand painted ones can not match the ones you have, to have them custom made exactly like the ones you have will be extortionate (trust me)
plese don't get the A**e with me about the fact you should buy more tiles when doing a tiling job, i dont have a crystal ball and you neglected to mention in your first post the previous owners had put the tiles up.
I didn't say that I put them up either, you just assumed it.
And I'm not particularly after an exact match. Just something to cover the new bricks/plasterboard to tide us over for a couple of years until the whole lot may be re-done perhaps. Something close will do.
