Are Ikea sinks compatible with standard waste fittings?

No.

I seem to remember
that their wastes are bottle traps and I'd prefer to go for a "traditional"
bend. Knowing that Ikea tend to be a bit non standard with some dimensions
(like needing 620 mm worktops for the base units) I thought I'd better try
to find out first because it'll be a 160 mile round trip to go back for the
fittings if I need them.

I used the Ikea waste fittings to couple up to the sink, but sawed
off after that and connected to standard UK trap with washing machine
inlets, etc. Spent a while rummaging through waste fittings in a local
plumber, to find bits which were a near enough match to saw up and
solvent weld to the Ikea bits (which don't solvent weld very well).

Also meant I could position the u-trap at the back of the cupboard,
for minimum interferance with the storage space.
