Stainless Under-Sink Grease Trap: Is This Commercial Interceptor Right for Your Kitchen?

A compact stainless under-sink grease interceptor for separating oil and water in commercial kitchens. Weigh the 18-20L capacity, 13.8-inch dimensions, and USD 49.03 price against your sink setup.

Last updated Aug 17, 2026

When hot water, food scraps, and cooking oils flow into a commercial drain, grease can coat the pipes and create expensive clogs. A grease interceptor sits under the sink and separates oil from water before the wastewater continues downstream. The challenge is matching the unit's capacity and connection sizes to your actual sink and grease load. This guide looks at the Commercial Grease Interceptor Grease Trap Stainless Under Sink Grease Trap US, a compact stainless option at a fixed USD 49.03.

Quick Verdict

If you need a compact under-sink interceptor for moderate grease output, this stainless unit is a strong candidate. Its 13.8 x 9.8 x 9-inch footprint makes it feasible for smaller prep sinks, food trucks, or low-volume kitchen stations. It is not built for heavy-duty continuous frying; understand your sink configuration before committing.

Who This Suits

This unit fits commercial kitchens, caterers, or food-service areas where cooking oils and greasy dishwater are common but not overwhelming. The separate wastewater inlet, water outlet, and grease outlet give you defined connection points for adapting to standard sink plumbing. If you deal with mineral, animal, or vegetable oils, the interceptor is intended to handle those oil types.

What Stands Out

The stainless steel material is intended to provide durability and a longer service life, and the unit is designed for separating oil and water, including mixed and emulsified oils. The package includes the grease trap interceptor, a drainage pipe, and a lid. The thread on the inlet head is even and smooth, which helps when connecting the trap to your plumbing. The listed price of USD 49.03 includes the accessories needed for installation, so there is no additional cost for the core components.

Meaningful Trade-offs

The 18-20L capacity is the most significant limitation. A sink line handling continuous frying or heavy dishwashing can fill this interceptor quickly, so plan for more regular grease removal. You also need to confirm the 4.8 cm / 1.9" inlet and outlet diameters match your existing drain pipe. The grease outlet is only 2.2 cm / 0.86", which is suitable for moderate grease accumulation but may be restrictive in high-volume scenarios.

Bottom Line

The Commercial Grease Interceptor Grease Trap Stainless Under Sink Grease Trap US offers a straightforward solution for separating grease from wastewater in a compact under-sink area. It is priced at USD 49.03 and includes the essential parts. If your kitchen's grease output stays within its capacity and your drain connections align, it is a practical choice.

The stainless interceptor measures 35 x 25 x 23 cm (13.8 x 9.8 x 9") and comes with a drainage pipe and lid. It is priced at USD 49.03. One concrete reason to choose it: it brings a dedicated under-sink grease trap at a clearly defined price with the necessary parts included. One concrete limitation: the 18-20L capacity means it works best for low-to-moderate grease loads; a busier sink will require more frequent grease removal.
