Picking an under-sink grease trap for warewashing sanitation grease can get tricky when two options carry the same product name and share the same core dimensions but differ in condition and cost. One is described as new and lower-priced; the other as used and higher-priced. Everything else is nearly identical, so your decision comes down to whether you want the new-condition unit at the lower price or prefer the used unit with its stable performance and high quality emphasis.
Quick verdict
Both options share the same 18-20L stainless-steel body and overall dimensions of 35 x 25 x 23 cm. Neither one offers a larger capacity or a different footprint in the comparison, so the practical differences are condition and price. For most kitchens, the new lower-priced unit is the more direct pick, especially if you prefer not to have used-condition as a variable. The used unit can still make sense if you specifically want a pre-owned unit and are comfortable with a higher price.
Side-by-side comparison
| Feature | New option | Used option |
| Price | USD 49.03 | USD 129.99 |
| Condition | New | Used |
| Capacity | 18-20L | 18-20L |
| Overall dimensions | 35 x 25 x 23 cm | 35 x 25 x 23 cm |
| Wastewater inlet | 4.8 cm | 4.8 cm |
| Grease outlet | 2.2 cm / 0.86 in | 2.2 cm / 0.86 in |
Where each option wins
The new option wins on condition and price. You get a new stainless-steel commercial grease interceptor with the same capacity and dimensions as the used unit, but at the lower price. The used option wins only if you deliberately want a used unit and prefer the stable performance and high quality emphasis. It does not bring a spec advantage to the table, so the higher price rests mainly on the used-condition preference.
Product notes
New option: Commercial Grease Interceptor Grease Trap
This is the straightforward choice if you want a brand-new unit without paying more than necessary. Highlights include creative design, durable material, beautiful appearance, and high reliability, along with a high-quality thread line on the head of the water-oil separator. It comes with one grease trap interceptor, one drainage pipe, and one lid. Its capacity and dimensions match the used unit, so you are not sacrificing size or footprint. The main thing to keep in mind is that the styling and material highlights are descriptive claims rather than quantified performance specs, so the comparison stays about condition and price rather than an upgraded specification list.
Used option: Commercial Grease Interceptor Grease Trap
If you are deliberately shopping for a used unit, this is the option that fits that need. Its highlights include stable performance, high quality, great durability, and an exquisite appearance, and it shows the same compact dimensions as the new option. The sticking point is price: the used unit costs $129.99 while the new unit costs $49.03, so you pay substantially more for the same capacity without getting a condition advantage. Choose it if used-condition is a preference rather than a compromise. Pause if you want to avoid a higher price for identical dimensions and capacity.
Final choice by use case
If you want the lower-priced new unit with the same capacity and dimensions, the new option is the clean pick for most under-sink warewashing sanitation grease setups. If you specifically want a used unit described as stable and high-quality, the used option will satisfy that preference, but the higher price buys no quantified spec advantage over the new unit.
