No, this replaced the one that Dom broke when he didn’t correctly hook it up to the new food disposal (we’re even since I broke the disposal).
We got ours at the Sears Outlet in Lawrenceville a few days ago and they did have a nice stainless steel Bosch that had a stainless interior. It has one little scuff mark on the bottom left corner, not very noticable. It was a little over $500. It may still be there since it wasn’t actually out on the floor yet, it was still in the back employee only section.
I’ve never heard of slate in a dishwasher. Are you sure that’s what it is?
The new one we bought has a plastic interior. Same as our old one and it held up just fine until Dom burned up the motor because he didn’t have the plumbing hooked up right after we put a new food disposal in.
