How to Choose a Cabinet Basin for Your Vanity: Size, Fit and Material
A cabinet basin — also called a drop-in basin — sits into a cut-out in the vanity top, with its rim resting on the countertop. It is the workhorse of hotel and residential bathrooms: simple to install, easy to replace, and available in widths from 600mm to 1000mm to match any vanity. This guide explains how to choose the right cabinet basin for your project, covering sizing, installation, material and what to confirm with your supplier.
What Is a Cabinet Basin?
A cabinet basin is a ceramic basin designed to drop into a countertop rather than sit on top of it. Unlike a vessel basin, which stands above the counter, a cabinet basin sits flush with the surface, creating a clean, integrated look with no raised rim to clean around. The rim flange carries the weight of the basin on the countertop edge.
This installation style is preferred in hotels and commercial washrooms because the flat surface is easier to wipe down, and the basin can be replaced independently without replacing the whole vanity. It is also the most common basin type in budget-to-mid-range residential bathrooms.
YINGJIE’s cabinet basin range covers widths from 600mm to 1000mm, with depths from 360mm to 500mm, so you can match virtually any vanity programme.
Step 1: Measure Your Vanity Before You Choose a Size
The most common mistake in cabinet basin specification is ordering by vanity brand rather than by actual countertop dimensions. Always measure three things:
- Countertop width: the basin must fit within the usable width, leaving at least 50mm on each side for the faucet and edge clearance.
- Countertop depth: the basin depth must be smaller than the countertop depth, with enough front and back margin for the rim flange and the faucet base.
- Cabinet cut-out size: the drop-in template of the basin must match the existing cut-out if you are replacing a basin.
The YJ-860B and YJ-860C series illustrate standard sizing: each is offered in 600, 700, 800, 900 and 1000mm widths, with a fixed 190mm height. The 860B has a 480mm depth for standard vanities, while the 860C offers a wider 500mm bowl for roomier counters.
Step 2: Match the Basin to the Countertop Depth
Cabinet basins are typically grouped by depth. In our range, the 890A series is the slimmest at 360mm deep — ideal for compact vanities and narrow bathrooms. The 890B, 891 and 899 series sit in the 390–440mm band, the most common range for standard vanities. The 892 through 898 and 900 series extend to 475–500mm for wide, hotel-style counters.
Here is the practical rule: on a standard 600mm-deep vanity with a backsplash, a 440–480mm basin leaves comfortable room for the faucet and countertop edges. Going wider than 500mm starts to crowd the countertop and complicates plumbing access.
| Series | Width | Depth | Height | Best fit |
|---|---|---|---|---|
| YJ-890A-80 | 800mm | 360mm | 170mm | Compact vanities |
| YJ-890B-80 | 800mm | 440mm | 190mm | Standard vanities |
| YJ-891-80 | 800mm | 400mm | 200mm | Deep-bowl preference |
| YJ-892-80 | 800mm | 480mm | 195mm | Spacious counters |
| YJ-893-80 | 800mm | 500mm | 190mm | Wide counters |
| YJ-898-80 | 800mm | 475mm | 210mm | Splash control |
| YJ-900-80 | 805mm | 475mm | 205mm | Premium suites |
Step 3: Understand the Installation Types
Nearly all cabinet basins use the same drop-in principle, but confirm two details with your supplier:
- Rim style: standard flat rim, or a subtly curved rim that creates a soft shadow line on the countertop.
- Cut-out template: ask for the exact template dimensions before ordering so your stone or laminate countertop can be cut correctly in one pass.
A drop-in basin should always be sealed around the rim with silicone during installation. The basin itself carries no weight from the countertop, so it is one of the most reliable installations in bathroom fit-out — and one of the easiest to replace during renovation.
Step 4: Material, Finish and Drainage
Our cabinet basins are high-fired ceramic with a glossy white glaze — the standard specification for hotel and residential projects. Glossy white is specified because it is the easiest finish to keep clean and the easiest to match across a project programme. Drain holes are pre-drilled to the standard size; pop-up drains and overflow configurations can be supplied on request for OEM orders.
Step 5: Confirm the Ordering Details
Before you finalise a bulk order, confirm these with your supplier:
- MOQ: 50 pcs per model per width.
- Lead time: 25–35 days depending on quantity and customisation.
- Mixed widths: most projects mix 600/800/1000mm widths — confirm the MOQ applies per width or per model family.
- OEM: custom logo, packaging, and glaze colour are available; for large hotel programmes we can supply matched sets with your vanity manufacturer.
- Packing: basins are foam-wrapped and shipped in export cartons on wooden pallets — confirm the packing method protects the rim flange, the most vulnerable part in transit.
Choosing a Complete Bathroom Vanity
While a cabinet basin solves the washroom layout puzzle, many buyers pair it with a complete bathroom vanity collection to match storage, mirror and basin in one set. Our hotel-grade sintered stone vanity and luxury vessel vanity are the two most requested models for UK hospitality projects.

Frequently Asked Questions
Q: What is the difference between a cabinet basin and a countertop basin?
A: A cabinet basin drops into the countertop so its rim sits flush with the surface; a countertop (vessel) basin sits on top of the counter. Cabinet basins are easier to clean around and are the standard choice for hotels and rental properties.
Q: What sizes are available?
A: Our cabinet basins are available in 600, 700, 800, 900 and 1000mm widths, with depths from 360mm to 500mm and heights around 170–210mm.
Q: How do I know if a basin fits my vanity?
A: Measure your countertop width and depth, then check the basin dimensions and its cut-out template. Leave at least 50mm clearance on each side of the basin.
Q: Can I replace an existing basin without replacing the vanity?
A: Yes — if the existing cut-out matches the new basin’s drop-in template. Measure the cut-out before ordering a replacement.
Q: Do cabinet basins come with drain holes?
A: Yes, all our cabinet basins have pre-drilled standard drain holes. Pop-up drains and other accessories can be supplied on request.
Q: What is the MOQ and lead time?
A: MOQ is 50 pcs per model; standard lead time is 25–35 days. Samples are available for evaluation before bulk orders.
Conclusion
Choosing a cabinet basin comes down to three numbers: countertop width, countertop depth, and the basin’s drop-in template. Match those, confirm the MOQ and lead time with your supplier, and the basin becomes one of the simplest, most reliable components of your bathroom programme.
