You could try Nitromors, a paint stripper. I would read the tin carefully before proceeding with this though, wouldn't want it to have any effect on your tiles.

Hi what kind of floor tiles are they ceramic, porcelain etc depending on what they are depends on what you can use on them, If the paint is coming off quite easily id suggest just try using some warm soapy water and a sponge with a scouring pad on the back to start with.

If it is not flaking to much then repaint but first go to b and q get some p.v.a water down with 3 parts water paint the whole area with it let it dry for 24 hours then paint on top should then be fine

Hope this helps David

Hi Sorry to hear things didn't go so well I would suggest a lot of elbow grease you could try nail varnish remover somtimes works or any other ethyl acatate cleaner or try Ajax alchohol based window cleaner. Please go careful if using different cleaners make sure the room is well ventilated. Also mixing different cleaners can give of deadly fumes especialy in a confined space such as a bathroom . Good Luck

Hi, try NITRO MORS all purpose paint and varnish remover. This will remove the paint and not damage the tiles at the same time. You can puchase at B&Q.
( you may possibly have to regrout the tiles).

plastic scotch pad and hot soapy water and a big jar of elbow grease. you might need to rake out some of the grout and then regrout because the paint will be hard to remove from it.

i know this is going to sound daft but use some petrol on a spuns it smell a bit but it fast and it works keep a window open in bathroom
