Modifying a sink base for non-IKEA apron-front farm sink
We modified a 36" IKEA sink base to hold an undermounted 36" Whitehaus Quatro Alcove fireclay farm sink.
This particular sink is 36" x 20" x 10" and weighs about 100 lbs. I intended to get the Domsjo sink base, but purchased the regular sink base instead, and it really made no difference in the end.
Because the sink is wider at the top than it is at the bottom, as an undermount, the only way it would fit into the 36" base was if the sides of the cabinet were cut down.
