In a rented house I wanted to remove toilet to lay new floor. The cistern was held in place with silicone and I have cur behind this. It seems that there are no drilled/cast holes through which to send screws to secure to wall. The make of WC is unknown though suspect it is cheap product from a shed. Has anyone else encountered this. The basin is also siliconed in place but it does have the two holes for fixing to wall. I know it a cowboy practice but I am tempted to do the same.
