I need alternative basin fixings for a cavity wall

[BritishBeef]

Hello!
I have just installed a new basin in my bathroom but it's not attached to the wall strongly enough. The reason is because it's attached to a tiled plasterboard wall with large cavity behind and the fixings which were recommended by my local plumber's merchants (These: http://www.screwfix.com/prods/71804/Fixings/Furniture-Fixings/Fischer-Basin-Fixing-Kit) aren't suitable and start to pull out once I start to tighten the nuts. The basin's fixing holes are large (about an inch or so) hence the fixings I was given in a plumbing merchants.

What alternative fixing can I use that is suitable for such large fixing holes in the basin and is also suitable for the plasterboard cavity wall.

NB: The basin is on a pedestal so the wall doesn't need to take the weight of the basin.

Any help greatly appreciated!

without fitting a baton behind the plasterboard to screw into,spring toggles can be used as a last resort.

As above with spring toggles and gripfill.

Thanks for the replies!
The trouble with the spring toggles is that there is no room to use a screwdriver to tighten them, only room for a spanner. Unless there's a fancy gadget out there?!

plenty of room for a screwdriver,if you find it difficult use a quarter drive racthet with a straight/pozi/philips bit in it.

You'll find that, even with a half-decent attachment to the wall, the gripfill will hold it steady enough* (except if toddlers decide to swing on it)




* assuming your tiles are propely attached!
