I notice that my new sink doesn't *quite* fit snugly onto the top of
my new pedestal (they were sold as part of the same suite), Apart from
fixing the sink to the wall, and the pedestal to the floor, is there
any need to use a filler of some sort (e.g. silicone sealant) between
the sink and pedstal ? - obviously not for waterproofness, but just no
make a good seat ?
