vinyl, plasticy stuff, also called lino or linoleum (dunno how to spell that one!), my uncles a carpet fitter so i know what you mean. we've got it in our bathroom, its been there like 20years, this place needs decorating!!
*tip* get a big roll of lino stuff, unroll it so you've got a masive area of it, then slide on it

brilliant fun if you're a little kid!
