can any one tell me if it safe to drill a intergrated fridge door ,
and is it safe to do so and not damamaging the fridge

Can?t say that I?ve ever come across an integrated fridge with
electrics or cooling pipes in the door. The latter would be a bit
tricky anyway.

So if it?s just a plain door, no problem at all. Of course you would
be best not to drill right through because the bolts (or whatever)
should be sealed to prevent moisture running into the insulation. Same
is true for the outside when cleaning. Silicone sealant under your
fitting will be fine but de-grease first.

To affix (towel rail etc) it would be best to use self-tapping screws.
A bolt right through to the insulation can?t be clamped hard because
the plastic inner would partially collapse against the insulation.
This would also reduce the efficiency of the insulation. So too would
the bolt right through but it would be minimal.

If self-tappers are not suitable you may need to cut out a small
rectangle of the plastic inner -- three sides so you can fold it back
-- and slice out a wodge of insulation. Re-insert with light gluing
after the bolt has been installed against the outside face.

Another alternative to clamp hard on the front is to drill a hole
large enough to get a socket onto a nut. The insulation can be
adequately restored with expanding filler. If you?ve never used the
stuff before, test it out to get a feeling for how much it will expand
and only inject enough so that it will just extrude as it could
compress the insulation. Let it set completely before you pare it off,
or even touch it, otherwise it sets to a hard solid lump. Foam wadding
would be almost as good, expanded polystyrene cut to size too.

If you want easy removal, you could use a long bolt and sleeve just
long enough to protrude through the inside. A nut on the sleeve would
clamp it hard against the front.

Several other variations on the theme, but as long as you take care
with the insulation I?m sure it will transform your space restricted
kitchen. (?) Most people never consider adapting household items --
seems not to occur to them, as if they are sacred objects designed by
a superior race. So respect to you.

As with Guzzi, never heard of electrics and cooling within the door
(except BOSCH appliances).

You can get clinch nuts which are nuts that fix to small holes in
sheet metal. This is the best way to screw something to the door, but
remember that fridges are made of extremely thin sheet metal.

Personally I would use an epoxy resin (two part, but not the quick
setting variety). Make sure you rough up the surface of the door
first, though.

PS remember to use stainless bolts, against rust

Hope this answers.

And I agree with thoughtful05. Thanks too thoughtful05 for
enlightening me on Bosch.
