We have just had a bathroom fitted and the wall is 'finished' ie tiled, grouted and ready to take the basin. The basin in question is free standing and nothing touches the floor so all weight is taken by the wall. When the stud wall was built the builder installed horizontal pieces of 4x2 (i think) around the height where the basin goes so that he will have something to attach the basin to. My question is what fixing should be used to attach the basin through to the wood work behind as i imagine they would need to be rather meaty as the basin has some significant weight in it.
many thanks
