Grease traps sit at the messy intersection of plumbing and daily kitchen cleanup. When hot water, oil, and food residue reach the drain, an interceptor that does not separate grease quickly can lead to clogs, odors, and more drain maintenance. For a warewashing sanitation and grease setup, the real question is whether a compact under-sink unit can handle your washdown routine without taking over the space beneath the counter.
Quick Verdict
The Commercial Grease Interceptor Grease Trap Stainless Under Sink Grease Trap US is a practical choice for a single sink station. Listed at USD 49.03, it brings four-stage filtration and an automatic shut-off for open-air placement. The 18-20L capacity makes it a fit for a food-prep sink or low-to-moderate wash station rather than a whole-building grease management system.
Who It Suits
This interceptor suits foodservice or catering kitchens where space is tight. The under-sink design keeps it out of walkways, and the compact footprint, about 35 x 25 x 23 cm, lets it work in confined plumbing spaces. The stainless steel body is relevant for a part that regularly meets oil and water. It handles mineral oil, animal oil, vegetable oil, mixed oil, and emulsified oily water, so it covers the typical range of kitchen grease.
What Stands Out from the Listed Details
The four-stage filtration stands out most. Instead of relying on one screen, the interceptor layers the separation process to keep oil from moving further down the drain line. The automatic shut-off is also useful: it allows the grease trap to sit in an open-air location and stop itself when rain arrives. That gives flexibility beyond a standard under-sink installation.
The 4.8 cm wastewater inlet and 2.2 cm grease outlet show a compact, low-profile design. If your sink drain is small and your grease volume is moderate, this geometry lines up well.

This unit is worth a close look when your drain line serves a sink that sees varied grease types. It is designed for mineral oil, animal oil, vegetable oil, mixed oil, and emulsified oily water, so it is not limited to one cooking style. The trade-off is the compact outlet: the 2.2 cm grease outlet is a small-connection design, so it fits best where the drain hookup is similarly sized.
Meaningful Trade-Offs
The main trade-off is size versus workload. An 18-20L interceptor is easy to tuck under a sink, but it stores less captured grease than a larger tank. If the sink sees one prep station with occasional frying, this size is workable. If heavy amounts of oily water flow into one drain all day, expect to empty it more often. No grease trap removes the need for maintenance; it just collects the grease in one place where it can be dealt with before it becomes a plumbing problem.
Bottom Line
The Commercial Grease Interceptor Grease Trap Stainless Under Sink Grease Trap US is a straightforward way to bring grease separation to a small sink area. At USD 49.03, the stainless steel design and the listed price make it a useful starting point for moderate kitchen use. The deciding factor is how much grease the sink actually sees. For moderate use, this is practical. For very high daily grease loads, capacity becomes the limit.
