The reason it is on back order is because Kohler had a factory burn down. They lost a lot of inventory, so no one will have it unless they ordered ahead of time and it is just sitting around.

I noticed yesterday that some places seemed to be getting some in:

I'm aware of the fire since we encountered the same thing with our cast iron bathtub for our kids' bathroom. But those tubs started to come in much faster so I was hoping the foundry was up and running by now. Apparently only 2 of 6 kilns are up and running according to Kohler.

Thanks, jhmarie. This is actually where I ordered it from and then they turned around and said it would ship in October (!) So I had to cancel that order. The same thing happened at Home Depot.

Your sink cabinet should have been designed specifically for the apron sink you specified. You may not be able to change sinks without changing the cabinet as well.

You cannot use a temporary sink because of the template issue.

Jemile - call them (Build.com) if it was a few weeks since you originally ordered. It says they have 20 in stock - yesterday it said 12, and a few weeks ago it said out of stock. I think they may be starting to come in.

Thanks, jhmarie, I'll try again but it was just Tuesday! I bought it through Build.com and then they changed their dates. I can't imagine they suddenly have 20. Ferguson Kitchen & Bath supposedly has a ship date of August so for now I'm going with them.

Let us know if you find anyone with some.

My Whitehaven, ordered after the fire, took about double the promised 45 days to arrive. I think my customers thought it worth the wait, but since you asked for alternatives, I'd suggest the new Quartz Luxe from Elkay. It has the short apron, so no special cabinets are necessary:

This sink was retrofitted; no need to pull the top.

I'd put in a thorough search as these are now intermittently coming back into stock. We had the same exact problem but it was early enough for us to switch to fireclay. Since then I've gotten email alerts from Home Depot a couple of times that they have it back in stock (and then sells out quickly). Definitely call around and actually talk to customer service folks too rather than just checking stock online.

Get fire clay.

I disagree with Zalco's rec of fireclay. There are really a lot of posts on this forum about crazing of fireclay, particularly around the drain. Also a lot of reports that fireclay is a more complex and expensive installation due to the irregularities of its edges and no two being the same.

Agree with friedajune about fireclay - this post made me sad:

I got one at Home Depot online 2 days ago. It was delivered today. Still don't have a delivery date on the the one I ordered through Ferguson's in mid-May....I was told 6-8 weeks then. My cabinets go in next week so I decided to bite the bullet and buy elsewhere. The only catch was I had to buy the sink as a package with a faucet - I bought the cheapest faucet available and I will get rid of it on eBay. Worth it to me to get the sink now!

Kohler is still having issues with the whitehaven. Has anyone found a cast iron alternative. My big hang up is the flange. We are cabinet dealers/installers so the whitehaven flange that covers the cut out is extremely important for us. The Elkay Luxe also has a flange but that is a composite so it doesn't have the same allure of the cast iron or fireclay (which is a cabinet makers nightmare).
