I want to hang a Villeroy & Boch Omnia Classic Close Coupled WC on a breeze block wall using bolts (and no metal frame). Is it best to hang the toilet on the wall with bolts or should I drill right through the wall and secure the toilet to the wall using nuts and bolts. What bolts should I use? If the bolts go right through the wall, is it also best to put them all through a metal plate on the other side of the wall to spread the pressure? One problem is, that I want to tile the wall on the other side of the cistern. There is a cupboard on the other side of the pan, so nuts and bolts there are not a problem. Can anyone please advise me accordingly. Thanking you in advance.
