Undermount Epoxy Sinks Overview

Undermount, underside or undercounter mount epoxy resin sinks are molded in one piece construction with inside corners coved, with the bottom dished or pitched to the drain outlet. All undermount epoxy sinks, produced of the same material as the epoxy resin countertops or bench toppings, are resistant to high mechanical or thermal shock and are chemical resistant. Dry Ice or liquid nitrogen however, should never be placed on the countertops or within the epoxy sinks, at any time or for any duration.

In accordance with SEFA 2.3. underside installation of epoxy sinks should be made using the supplier's recommended chemical-resistant sealing compound or adhesive such as Smooth-On PC-3 epoxy adhesive or Dow 786 silicone sealant.
Apply chemical-resistant sealant to the top edge of the sink rim and the underside of the countertop work surface and firmly secure the sink to the underside of the epoxy or solid phenolic counter top, while using supplier's recommended sink supports (see below). Adjust sink into position and secure the underside support rods to prevent movement. Ratchet up the adjustable nut / bolt "J" hook system to create a tight fit of sink to countertop underside. Remove excess sealant or adhesive while still wet or apply additional sealant under the countertop edge to form a chemical and leak proof seal. This should produce a tight and fully leak proof joint seal to prevent liquid migration into the cabinets.


NEW 2022 MODEL U30U-CR (* below)

L-30CR-2X-1 Based on industry demand for a true undermount double bowl sink with flat wall slope, we now offer a glued U30-U Double Bowl Epoxy Resin Sink.

Based on the size of the sink cabinet and the depth of the countertop, the U30-U double bowl sink can be oriented vertically or horizontally, per the attached cut sheets.

If a glued sink construction is not required, the D30D Lipped Drop-In sink can be used as a undercounter mount application.
