Drilling porcelain tiles

[hern]

I have fitted Italian travertine porcelain tiles to wall and floor in our bathroom - and now find i cant drill them to put in the waste pipe and screw the toilet down and screw the shower cubicle to the wall.

Can anyone advise how to getr over this problem please. I realise I can mastic the toilet (probably) but the waste pipes and shower pose a more serious problem.
Thanks is anticipation of your help

Jason has already answered your question in the last place you posted it.

Yes - thanks. I am still unable to locate a bit to drill a smaller hole for toilet screw and shower screw inserts. B and Q / Plumco etc not able to help either with supply or advice.

One guy is suggesting mastic-ing the toilet to the floor and wall - is this sensible?

Thanks. Topps Tiles have in fact now supplied me with 6mm and 8mm diamond tipped bits which appear to work slowly but fine.
