A few years ago I installed a WC on a ceramic tiled floor, and bedded it
in a sharp sand & cement mix of about 1:1. Since then it has cracked out
twice, so each time I have weakened the mix. It's just done it again, so
I guess I still used too strong a mix last time.

Any suggestions?


I can't understand why people still do this, surely this is the way they did
before the 1960s?
The 5 bogs I've fitted over the years all had holes to screw them to the
floor.
Some even came with stainless steel double ended screw/bolts to make the job
easier..


And mine is happily working with the one screw I managed to drill, and a
bed of silicone sealant underneath. Purrfect.
