Of course a standard wood cradle will work, although I prefer aluminum channel stock. its stronger and won’t rot. It’s just standard framing techniques, just like building a wall . Maybe you are misunderstanding how to build one. Show pictures of your attempt. A standard cable type HUSH will work as well. So will any type of harness. There’s nothing special about any of this.

A Kohler Whitehaven slipcover sink IS far easier to install, and a much more durable choice than an off brand fireclay that will chip and craze, and has no uniform sizing expectations. This is a permanent install. There aren’t Joe Corletts around every corner to fix decisions like that. Don’t cement this in stone.

The CoreGuard sink base is a big upgrade. It is not standard construction. It had to be added as an upgrade by your designer, and was worth every penny. Especially for a farm sink base that gets a lot more water damage than a standard one because of how farm sinks drip everywhere.

Keep your doors and ask Kraftmaid to remake their standard farmsink base with a plywood end upgrade (or order in all wood Vantgage series). You can specify the sink base be "wood" or "coreguard" with Kraftmaid. I don't think you can do a sink harness with the Coreguard material. It's never come up. I don't use the Coreguard option so I'm not sure on that.

You could also just take the front off and built out your own cabinet box if you're in a hurry.

Stiffen the plastic sides with metal or wood and use the Pete's please.

how did you end up doing this?

OP im just wondering how yall ended up installing this? im in the same boat now. thanks thanks!

Kraftmaid offers a few types of sink base construction: the standard engineered (MDF) box construction, plywood construction or the "plastic" construction called COREGUARD (engineered polymer construction). The Coreguard is for people that want a sink base that won't get ruined if their plumbing leaks. Great concept, but not sure it's practical. I don't care for it, myself. They offer both a standard sink and a farmhouse/apron sink cabinet in this Coreguard.

@itsourcasa Your sink and drip ledge are lovely and seem just perfect for your kitchen. I'm interested in an apron front sink, however, I want one that is flat and thin in the front, not rounded, thick or curvey. So a more modern look rather than vintage, but with all the charm of an apron front sink.

How is fireclay different from cast iron/enamel? Does fireclay need to be babied? How would you rate it now that it's been in use for a while? Where did you buy it? Did you end up using a Pete's Support kit? I'd appreciate any pictures of your kitchen you would post. I don't know if it's possible to PM folks on Houzz (you could on the Garden Web) but I would like to know how your blue cabinets from Kraftmaid are holding up. Do they ever seem too dark? Do you know which Ben Moore navy blue or Sherwin navy blue that you would compare the kraftmaid Midnight color to? Thank you!

K Hk - what solution did you end up coming up with for your farmhouse sink and Coreguard cabinet issue? We are currently running into the same issue. Thanks!

I know this is an old post but looking to install a farmsink and was wondering if anyone has gad luck with replacing their current sink cabinet. i was looking for something specific I had seen online on pinterest but was unable to find anything close to it anywhere. Maybe this is a custom piece or buffet server? any ideas or suggestions welcome! My current sink cabinet size is a 42 inch. thx

That's about 6K of custom sink cabinet there. Plus the counters, sink, and faucet.

Dana, I'm curious as to why you're replacing your sink base cabinet? You don't have to in order to get an undermount apron sink, you just get a short apron sink and use the existing cabinet. The bowl remains the same depth.

Yes i did have getting the short apron farm sink in mind but thought since i was having the cabinets painted i just wanted the sink to look more deco than the rest of the kitchen. thank you

What you end up doing installing undermount on kraftmaid coreguard sink base
