The difficulties with the manufacture and safe storage of an apron sink in Silgranit (which can crack in storage and transport), vs. in cast iron (which would NOT crack), probably make this uneconomical. The front flap of the apron sink might be especially fragile, I would expect it to be, because of the full bend around the edge, and the hanging part.

Also, demand for these sinks is probably lower, Silgranit is not the right material for this shape.

Just a guess.

I have no idea why they don't, but I sure wish they would add a farm sink to their silgranit line. I've wondered the same thing for over a year.

I have actually wondered the same thing...I suspect it is just that they aren't convinced there is a big enough market, though they might be wrong about that.

Your friend does have some options other than fireclay and stainless. There are lots of copper farmhouse sinks, and I have also seen them made from concrete, teak wood (see William Garvey in the UK), bamboo (see Lenova and Alfi), and a number of natural stones including granite, slate, marble and soapstone. Depending on her counter choice, one of those could work.

Finally...Mitrani at least used to make farmhouse sinks made from quartz composite. They only came in white, though, and they seem to have been discontinued (though some online retailers look like they have them in stock). There are some previous threads about these sinks, and there are some members who own them and seem to be happy. See, for example, Shelayne's post with pic in the linked thread.

Chez_carol, you are bringing up a thread that is 5 years old. The Silgranit apron front sinks were introduced this year.
