JH-PS004 vs JH-PS003 — Which Should You Choose?
Both models share the same width and length footprint, so the deciding factor is basin depth:
- JH-PS004 (Small Sink B): 180 mm deep basin — ideal where under-bench clearance is limited or a shallower basin suits the workflow.
- JH-PS003 (Small Sink A): 280 mm deep basin — choose this when you need a deeper basin and have the clearance for it.
If you’re unsure which depth fits your bench, share your under-worktop clearance, and we’ll confirm the right model.
Key Features
- Good chemical resistance — High-grade PP resists many common laboratory reagents. Because performance depends on the chemical, concentration, and contact time, confirm compatibility for your specific application.
- Lightweight and easy to move — The PP body weighs far less than epoxy resin or ceramic basins, simplifying handling, transport, and installation during fit-outs.
- Durable, distortion-free construction — A maximum edge thickness of 7 mm helps keep the basin smooth and flat through daily use.
- Scratch-resistant matt lip finish — The matt finish on the lip resists scratches and matches the look of most lab worktops for a consistent bench appearance.
- Easy to clean — The smooth, non-porous surface resists staining and doesn’t absorb chemicals, so routine wipe-downs keep the basin hygienic.
- Complete accessory set — Ships with high-grade PP overflow pipe, stopper, and filter/PP basket trap as standard, so the unit is ready to install on arrival.

Sizing guidance for the JH-PS004:
- Shares the same width and length footprint as the JH-PS003 (Small Sink A), but with a shallower 180 mm basin — ideal where under-worktop clearance is limited.
- For a deeper small basin, choose the JH-PS003 (Small Sink A).
- For larger wash-up needs, step up to the JH-PS002 medium sink or the JH-PS001 big sink.
Share your bench depth and under-worktop clearance, and we’ll confirm the right model for your layout.
Applications
The JH-PS004 is designed for compact, space-limited settings where a shallower basin is an advantage:
- School and teaching labs — The compact, shallow design suits classrooms and instructional benches where space is tight and a smaller basin meets everyday needs.
- Compact workstations — A good fit for benches with limited surface area or reduced under-worktop clearance.
- Auxiliary wash-up points — Practical as a secondary rinse or hand-wash station alongside a larger main sink.
- Light-duty lab wash-up — Suitable for routine rinsing of glassware, tools, and small equipment.
Installation Options
Thanks to its light weight, the JH-PS004 supports two mounting methods:
- On-worktop (drop-in): The sink sits on top of the bench surface for straightforward installation.
- Under-worktop (undermount): The sink mounts beneath the worktop for a clean, flush finish.
The shallow 180 mm basin is especially helpful for undermount installation where under-bench clearance is limited, giving you more room for plumbing and cabinet space below the worktop. For a leak-free result, keep the worktop surface level and properly seal the joint between the sink and tabletop. Choose the method that best matches your bench design and plumbing layout.

FAQ
What material is the sink made from?
The JH-PS004 is made from high-grade polypropylene (PP), chosen for its balance of chemical resistance, strength, and durability. A maximum edge thickness of 7 mm helps keep the basin smooth and flat during repeated daily use.
What chemicals can the PP sink handle?
High-grade PP offers good resistance to many reagents used in labs. Because performance depends on the specific chemical, concentration, and contact time, we recommend confirming suitability for your application. Send us your main reagents, and we’ll advise on compatibility.
What is the difference between the JH-PS004 and JH-PS003?
Both share the same width and length footprint, but the JH-PS004 has a shallower 180 mm basin, while the JH-PS003 is 280 mm deep. Choose the JH-PS004 where under-worktop clearance is limited, and the JH-PS003 when you need a deeper basin.
What size is the JH-PS004?
The interior basin measures 380 × 270 × 180 mm. The exterior width appears in our records as either 330 mm or 340 mm, so we recommend confirming the exact exterior dimensions with our team before ordering to ensure a precise bench cutout.
Which labs is the JH-PS004 suitable for?
Its compact, shallow design is best suited to school and teaching labs, compact workstations, and auxiliary wash-up points where bench space or under-bench clearance is limited.
How is the sink installed?
The JH-PS004 supports two mounting methods: on-worktop (drop-in) and under-worktop (undermount). The shallow basin is a real advantage for undermount installations with limited clearance. For a leak-free result, keep the worktop level and seal the joint between the sink and tabletop.
What accessories are included?
Each sink ships with a complete set of high-grade PP accessories: overflow pipe, stopper, and filter/PP basket trap. These come as standard, so the unit is ready to install on arrival.
How do I request a quote?
Send us your bench depth, under-worktop clearance, preferred mounting method, drainage needs, color, and quantity. A drawing or bench layout helps us confirm the correct model and quickly prepare accurate pricing.
