Undermount Farmhouse White Cast Iron Sink
Undermount Farmhouse White Cast Iron Sink


Undermount Kitchen Sinks started their entry into the Kitchen Remodels in the 70's and Steadily they have increased in Popularity.

The Undermount Style is a Clean Impressive Look, Easier to keep clean around the Edges.

A Local Kitchen Remodeler claims the Undermount Farm House Sink, like in the Image above, Is the most popular in Today's Kitchen Remodel or Countertop Upgrade.

The lighter Stainless Steel undermount Sinks can be placed on the Underlayment under the Countertop Material. Silicone Caulk is used to Hold the Sink in Place for the Countertop Material on top.

The Heavier Composite and Cast Iron Sinks under mounted, will require a Substantial Support to hold the Sink up. The Heavy Sinks should NOT be supported by the Underlayment.

Possible Undermount Problems

Sinks can Wear Out, Break, Chip or become Discolored. Get a Good Sink that will outlast your Countertop. If you choose Granite, Quartz or Quartzite replacing a Undermount Sink without breaking the Countertop Material may not be possible.

Kitchen Sinks Do Not have an Overflow, Over filling a Sink that is Undermounted, will allow Water to get between the Countertop Material and the Underlayment and could cause possible Mold Problems.

Overflow Problems are 100% Preventable be Watchful don't fill more than half full. Check the Caulking between the Sink and Countertop often. Use a Mirror with good Light, inspect carefully.

Top Mount

Top Mount or Drop In Sinks are placed in a Cut Out less than the size of the Sink on the Countertop Material.

Top Mount Sinks have Metal Clips that clamp the Sink and Countertop together. Some Installers Do Not use the Clips they just Silicon the Sink to the Countertop, It does work but I have seen where the Cut-Out was oversized and the Silicon really was not enough.

It is recommended to use Clear 100% Rubberized Silicone Caulk to Seal the Lip of the Sink to the Countertop Material.

A word of Caution, 100% Rubberized Silicone Caulk is NOT Water Soluble and will always leave a film. You should not expect to wipe off any excess that came out from under the Sink Edge.
