I need to increase the diameter of the holes in the
loo by 4mm. What is the best way to do it ?
Is there some sort of tapered boring tool for
china/earthenware (or whatever loos are made with) ?
I would echo the cautions of the other posts.
But Harry Bloomfield managed to drill a 6 mm hole through the shelf
across the back of a washbasin (much to my surprise; see his posts of
the 11th and 12th of this month), and loos and washbasins are made of
the same stuff (vitreous china, aka porcelain in common parlance), so
you may also be successful. He started with a small drill, 4mm, and
gradually increased the diameter until he got to the size he wanted,
6mm. I would take it very slowly and gently with minimum force, and be
prepared for tears! He may offer more advice.
But much safer to change the size of the fixings on the loo seat.
Thanks to all for the warnings - which I've heeded.
It's not possible to reduce the distance between the seat fixings.
But by leaving off the plastic sleeves intended to go round the
shanks of the fixing screws, those screws just fit into the inside
edges of the holes ! So problem solved.

I suspect those sleeves are provided to protect the porcelain from damage by the threads of the screws or studs during tightening or under mechanical impacts.
You might want at least to put some protective tape around them instead.
If obliged to bore-out a hole in porcelain, I would use a Dremel with a grinding bit. Laborious but at least no danger of cracking.
