Ikea kitchen sink and waste disposal

[Toodog]

Does anyone know what size the waste outlet (plug hole) is for a ikea stainless steel sink and will an insinkerator waste disposal fit? I am hoping to fit an insinkerator waste disposal unit to a ikea norrsjon sink.

The waste disposal unit will have a different thread to the supplied Ikea waste. There is an thread adapter available but the easy way is to use a different waste from the likes of McAlpine and others.
