Hi all

The lack of a service void on IKEA kitchen cabinets has been discussed
several times here. In my case (if I choose an IKEA kitchen) this will
be as issue under the sink as there are two pipes running horizontally
behind the sink unit and the adjacent corner unit. Could a solution be
simply to miss out the hardboard backing board and cut notches in the
side-walls of the base units to accommodate the pipes? Presumably the
backing board is there to give rigidity rather than load-bearing
strength so perhaps I could use some angle brackets instead in order to
give the base units rigidity?

thanks

Probably not a good idea to do it this way. The backing board on knock
down carcasses is there to prevent it from being pushed sideways.
The problem is that if this does happen at all, the load bearing
capability fails rapidly - think of the effect of a cardboard box with
the end flaps all open.

Angle brackets are not really a good way either because they are
located only in the corners and are liable to bend quite easily - even
the steel ones.

A better solution would be to cut some strips of softwood (not less
than 100mm or so wide and say 35mm thick) and fit them side to side at
top and bottom of the carcasses at the back, screwing through the
chipboard into the sides of the softwood and then the ends. This will
give you a fairly rigid structure. You can then notch out the sides
of the chipboard sides of the carcasses to take the pipes.

Finally you can trim the supplied rear panels and fit them to the
softwood with dome head screws.
