The farmhouse sink must sit on the custom supports built inside the farm sink base cabinet.
The top of the farmsink must be level with cabinet tops before the countertop slab is lifted in place.
After the slab is positioned in place and the seams have been epoxied together, come back to the sink and make sure the sink is sitting even under the slab edges before gluing the top rim of the sink to the underside of the countertop with silicone.
Note: Allow silicone 48 hours to fully cure before hooking up the sink plumbing.
