Still in the downstairs cloak, fitting a toilet roll holder. Dropped a
screw, rested my forearm on the lid of the WC to reach down & get it & the
piggin lid cracked in half! As thick as a fag paper. Replaced it like
for like from B&Q for £8.

There are two British Standards for WC lids. Only one includes the
requirement to support an externally applied weight.
