Question: Do we need to purchase anything else - like a sink strainer or a basket strainer? It shows those accessories - but doesn't say if you must have them.
Document: We bought this sink many years ago. Never got around to writing a review. So why review the sink now you ask? We are renovating our kitchen and we like this sinking we are reusing it. It's deep, cleans well and looks great.
Bought this sink for a kitchen renovation. Researched sinks online and in a local plumbing showroom. Sink retails for $700+. I think MSRP on Elkay website is $900+. I was a little reluctant ordering it hoping it wouldn't arrive dented and scratched. Order said would take additional 1-2 days to process. However, it arrived 2 days after I ordered it in great condition, packaged in an Elkay box with instructions, specs and template. Great purchase!
This was a great buy and much cheaper than buying it a local home store. Usually if something is close in price, I would rather just get it at a local store, but the price wasn't even close. Regarding the sink, it is perfect, with one side being deeper and larger which is perfect for washing larger items. We just installed new granite counters and this sink look perfect with it.
