Product Reviews

Anthem Cast Iron Undercounter Kitchen Sink with 5 Hole Drilling 5 5 2 2
No regrets! I researched many undermount sinks before purchasing this one and considered others that have a combination of one small and one large bowl. I purchased the custom wire racks that fit inside and am very pleased. Glad I chose the two equal sides because it's great for handwashing delicate china that you want to allow to air dry inside the bowl on the wire racks. June 6, 2011
Awesome sink We absolutely love this sink. The extra inch in depth makes a big difference when washing pots, and the lower divider makes it easier to transfer items from one side to the other without spilling. One thing to note is that the basin on the right side is slightly smaller than the left, but it doesn't seem to make much of a difference. We are very happy!! February 27, 2010

Are there any basin racks in white to fit this sink?

Unfortunately the only basin rack that fits Kohler's K-5840-5U is model K-6157 and is only available in the Stainless Steel finish.

What drain strainer and garbage disposal do you recommend with the K-5840-5U?

Question about all undercounter sinks. How are they installed to cancel out water seepage? Can they be removed from below if damaged and needing replacement?

Under mount sinks require the use of a sealant between the counter and sink. You generally have to remove the counter top to remove the sink.

Do all five holes need to be used, or can some be covered/sealed when the sink is installed?

Not all five holes need to be used. You can acquire an escutcheon plate that can cover up the unused holes or you can use single hole pluggers.

Why don't we show the price?

Like many retailers, Build.com can choose to set its own prices independently. And even though manufacturers require Build.com and other retailers to display a product's "minimum advertised price" (or MAP), the retailer can choose to sell for less than that. But the price must be conveyed in other ways, and each individual manufacturer's MAP policy determines where the price can be seen.

To see the price for this product at Build.com, you'll need to place it in your shopping cart, and maybe even proceed to final checkout. If you're not ready to buy the product, simply remove it from the cart.

Build.com apologizes for any inconvenience. We'd just like to offer you the chance to save extra money while we adhere to manufacturers' MAP policies. Build.com is also working to educate manufacturers on how their policies impact customers and their buying behavior.
