If the tile is that slippery then what about just replacing it? Yeah, it's a messy job but if the tile is "that bad" then it's probably better to just get rid of it and replace it with something less problematic.
Otherwise most stores with a housewares department are going to have rubber-backed mats suitable for bathrooms. Get one of those first, it'd certainly be a lot cheaper than a tile job. But then again, a tile job is probably a lot cheaper than a busted hip from falling down...
