The fittings that come with the basin are a pair of headless bolts
(with a flat bit in the middle for screwing into the wall), two metal
washers, a pair of polythene sleeves with 4mm thick polythene washers
at one end, and two nuts.

I am assuming that the nylon washer and the metal washer go back to
back so that the basin can be as flush against the wall as possible, or
is there a reason to have the nylon washer between the basin and the
wall?



On a separate note, the pedestal and the basin (both B&Q "Barcelona"
brand) don't seem to be an exact fit. Are these tolerances usual? I
mean, how difficult can it be to use the same mould for manufacturing
the basin and the pedestal?

Probably to accomadate sliding a tile down behind the basin if tiling has
not been done before fixing the basin to wall?

Wall - basin - polythene washer - metal washer - nut.

The plastic is there to even out the load from the metal washer which is
there to spread the load from the nut.

Screw the headless bolts in. Hang basin onto them then place on the
nylon washer followed by the metal washer and nuts to secure.

Sounds about right. Most sanitaryware is like that.

Make sure you use correct fixings for the wall against which you're
attaching the basin.

IF plasterboard:
If a stud wall chop out section of plasterboard, add a horizontal
noggin, replace, tile over and screw into noggin.
If breeze block behind then chop out plasterboard, attach a sheet of
18mm ply to the wall behind the sink, tile over and screw into plywood
behind.

IF brick/plaster:
No worries just drill correct size hole and using rawplugs supplied
with fixing kit.

Others may say just use plenty of silicon to ensure good adhesion but I
wouldn't like to trust it! For example at Uni a girl once ****ed in her
bedroom sink and it fell of the wall flooding the corridor.

Some people would pay to see that.

And it's probably a good idea to put a thin layer of plumber's mastic or
silicone in the wall-basin join, rather than tightening two ceramic surfaces
directly onto each other?

Unless you waited till it had set then any high points will just touch
through the mastic anyway and you'd be back to where you started.

For all that, I do put a thin bed on the wall first but that's more to
do with sealing thoroughly than stability.
