Deep Kitchen Sinks
Stainless steel deep kitchen sinks in standard pressed depths and custom handmade options for OEM, wholesale, and project supply.
Deep Kitchen Sinks Supplier & Manufacturer
Matrix supplies and manufactures stainless steel deep kitchen sinks for kitchen brands, importers, wholesalers, retail programs, project buyers, and OEM customers. A deep kitchen sink is not one fixed product type. It can be handmade or pressed / drawn, single bowl or double bowl, undermount or top mount, simple or workstation-style.
For pressed / drawn models, bowl depth is usually around 180mm and depends on mold availability, forming depth, and material stability. For deeper or custom-depth programs, handmade deep sinks are usually the better choice because the structure can be adjusted more flexibly.
For buyers, the key is not only choosing a deeper bowl. Bowl depth, cabinet clearance, drain height, plumbing space, installation type, drain position, accessory fit, surface finish, packaging, and repeat-order consistency all affect the final product program.
What Is a Deep Kitchen Sink?
A deep kitchen sink is designed with a deeper bowl than standard sink models, giving users more vertical space for washing larger cookware, trays, pans, and kitchen tools. Deep sinks are commonly used in modern kitchens, workstation sink programs, farmhouse-style kitchens, apartments, and project kitchens where washing capacity matters.
For B2B buyers, deep sink should be understood as a bowl-depth choice that can be combined with different manufacturing methods, installation styles, bowl configurations, finishes, and accessories.
A deep kitchen sink can be:
- handmade or pressed / drawn
- around 180mm depth for many pressed / drawn models
- 200mm, 220mm, 230mm, or custom depth for handmade models when feasible
- single bowl or double bowl
- undermount or top mount
- workstation or standard basin
- apron front or standard front
- brushed stainless steel, black, PVD, or Honeycomb surface
Note: A deeper sink can improve washing capacity, but it must be checked with cabinet height, drain position, plumbing layout, countertop type, and accessory clearance before production or project approval.
Pressed / Drawn Depth vs Handmade Custom Depth
Not every deep sink should be evaluated in the same way. The available depth depends heavily on the manufacturing method. Matrix can supply deep kitchen sinks through both methods depending on your program needs.
Pressed / Drawn Deep Sinks
Pressed / drawn deep sinks are formed by mold. Their depth is usually around 180mm, depending on the existing mold, stainless steel thickness, forming depth, and corner stretching. This option is suitable for standard programs where repeatable shape, controlled cost, and stable volume are more important than custom depth.
Best For:
- Standard deep sink SKUs
- Wholesale sink programs
- Retail replacement lines
- Apartment and rental housing projects
- Cost-controlled volume orders
Key Points to Confirm:
- Existing mold depth (typical ~180mm)
- Formed thickness after drawing
- Corner and sidewall stretching
- Rim and edge profile
- Batch consistency
Handmade Deep Kitchen Sinks
Handmade deep kitchen sinks are more flexible for custom depth because they are fabricated from stainless steel panels. They are suitable for 200mm, 220mm, 230mm, or project-specific depths when the cabinet, drain height, plumbing layout, and installation method allow.
Best For:
- Custom deep sink programs
- Premium kitchen collections
- Deep workstation sinks
- Deep apron front / farmhouse sinks
- OEM sink programs
Key Points to Confirm:
- Target bowl depth vs Cabinet clearance
- Drain height & Plumbing layout
- Welding and polishing quality
- Radius and corner consistency
- Packing protection
Available Deep Kitchen Sink Configurations
These are not mutually exclusive categories. A deep kitchen sink can combine several options, such as deep + single bowl + handmade + undermount + workstation, or deep + pressed / drawn + top mount + around 180mm depth.
Deep Single Bowl Kitchen Sinks
Provide one open basin with more vertical capacity for cookware, trays, and larger items. Cabinet width, drain height, and plumbing clearance should be reviewed.
View Single Bowl Sinks →
Deep Double Bowl Kitchen Sinks
Provide more capacity while keeping two separated work zones. Buyers should review bowl ratio, divider height, dual-drain layout, and cabinet space.
View Double Bowl Sinks →
Deep Undermount Kitchen Sinks
Create a clean countertop transition while offering more bowl capacity. Rim flatness, cutout size, bowl depth, and cabinet clearance should be confirmed.
View Undermount Sinks →
Deep Top Mount / Drop-In Sinks
Practical for replacement, retail, and apartments. Pressed / drawn top mount deep models are often around 180mm depending on mold.
View Top Mount Sinks →
Deep Workstation Sinks
Combine washing capacity with accessory ledges. Bowl depth, ledge height, accessory fit, drain position, and under-sink clearance should be checked together.
View Workstation Sinks →
Deep Apron Front / Farmhouse Sinks
Combine deeper capacity with a stronger front-facing design. Usually better supported by handmade construction when deeper custom requirements are needed.
View Apron Front Sinks →Handmade or Pressed Deep Sink — Which One Fits Your Program?
| Buyer Need | Handmade Deep Sink | Pressed / Drawn Deep Sink |
|---|---|---|
| Typical depth range | Custom depth such as 200mm, 220mm, 230mm when feasible | Usually around 180mm depending on mold |
| Depth flexibility | Higher | Limited by mold and forming |
| Custom size | Easier to support | Usually based on existing mold |
| Workstation ledge | Easier to support | Depends on mold and structure |
| Cost structure | Higher | More cost-controlled |
| Order volume | Suitable for OEM and premium lines | Strong for repeat volume |
| Forming risk | More fabrication control | Needs formed thickness and corner stretching review |
| Best for | Premium, custom-depth, workstation, apron front programs | Wholesale, retail, apartment, standard 180mm deep sink programs |
If your market needs 200mm, 220mm, 230mm, or project-specific depth, a handmade deep sink is usually the more practical choice. If your program needs stable volume, standard sizing, and cost control, a pressed or drawn deep sink around 180mm may be the better option.

Top-Mount vs Undermount Installation for Deep Kitchen Sinks
Top-Mount
- Easier drop-in installation
- Visible rim supports the sink edge
- Useful for renovation, retail, apartment, and replacement projects
- Requires countertop opening, rim sealing, and faucet hole check
Undermount
- Cleaner countertop appearance
- Usually needs more precise cut-out
- Suitable for modern kitchens, showroom displays, and premium projects
- Requires mounting support, sealing, and cabinet clearance review
Which Installation Fits Your Deep Sink Program?
Choose top-mount when the project needs easier installation, visible rim support, faster replacement, or broader renovation compatibility. Choose undermount when the buyer values a cleaner countertop transition, premium kitchen presentation, and precise cut-out control. For deep sinks, always confirm bowl depth, cabinet clearance, drain connection and accessory fit, and support before sample approval.
Send Deep Kitchen Sink RequirementHow Buyers Should Choose a Deep Kitchen Sink
For professional buyers, choosing a deep kitchen sink should start with the target depth, cabinet structure, and installation requirement. A 180mm pressed / drawn sink for a volume retail program is different from a 220mm handmade workstation sink for a premium kitchen line.
Confirm the Target Bowl Depth
Decide whether the market needs a standard deep option around 180mm or a custom deeper option such as 200mm, 220mm, or more. More depth is not always better if cabinet clearance or drain height is limited.
Choose the Manufacturing Method
Select pressed / drawn if the required depth matches available molds and the program needs stable volume and cost control. Select handmade if the program needs custom depth, sharper lines, workstation ledges, or premium positioning.
Choose the Installation Type
Undermount works well for clean countertop transitions. Top mount / drop-in is better for replacement and easier installation. Apron front works for farmhouse-style or design-led kitchens.
Check Cabinet & Plumbing Clearance
Bowl depth, drain position, garbage disposal space, P-trap layout, and under-sink storage must be reviewed before production.
Match Accessories & Surface
Deep workstation sinks need proper ledges and accessory fit. Surface finish should match the target channel and expected use.
Confirm Packing & Order Plan
For wholesale and project supply, carton label, SKU control, accessory packing, and pallet plan should be confirmed before shipment.
Why Buyers Choose Deep Kitchen Sinks
More Washing Capacity
A deeper bowl provides more vertical space for cookware, baking trays, pans, and larger kitchen tools.
Better Fit for Premium Lines
Custom handmade deep bowls work well with workstation designs and premium sink programs where users expect more space.
Useful for Projects
For some project kitchens, a standard deep sink around 180mm can improve practicality without custom construction.
Flexible Positioning
Deep sinks can be developed as handmade custom models, workstation sets, or selected pressed models for volume programs.
Bowl Depth, Cabinet Clearance, and Drain Height
A deep kitchen sink should not be selected by depth alone. Buyers should review bowl depth together with cabinet height, drain position, garbage disposal clearance, plumbing layout, and under-sink storage. A sink that looks ideal in a product photo may create installation issues if the cabinet and drain layout are not checked.
Technical Checklist:
- Sink outer size
- Bowl inner size & depth
- Cabinet width & height
- Drain position & height
- Garbage disposal clearance
- P-trap layout
Drain Position and Under-Sink Space
Drain position is especially important for deep kitchen sinks because deeper bowls reduce the available space below the sink. Buyers should confirm whether the market prefers center drain, rear drain, or offset drain, and how the drain location affects storage, plumbing, and garbage disposal placement.
Professional Note: Rear or offset drains may help improve usable bowl workflow and under-sink storage, but they must be checked with cabinet design, plumbing layout, and garbage disposal requirements.
How to Choose the Right Drain Position →Material & Surface Architecture
Precision-engineered for demanding environments. Our deep kitchen sinks are configured with variable stainless steel gauges, advanced surface treatments, and PVD color profiles to align precisely with your market positioning and channel strategy.
Acoustic & Thermal Shield
Deep vertical bowl surfaces require superior acoustic management. Our comprehensive EVA sound pad matrices and heavy-duty anti-condensation coatings ensure silent operation and absolute cabinet protection.
Never treat sound pads as mere visual features. Coverage area, adhesion strength, and thickness consistency directly dictate perceived product quality and lower after-sales friction.
Accessory-Matched Deep Sink Sets
Deep kitchen sinks can work well with accessories because the deeper bowl provides more usable working space. However, accessories should be matched according to bowl size, depth, inner radius, ledge structure, drain position, and target channel.
Common Accessories:
- Drainer / Strainer
- Bottom Grid
- Basket / Colander
- Stainless Steel Dish Rack
For Deep Workstation Models:
- Chopping Board
- Roller Shutter
Where Deep Kitchen Sinks Are Commonly Used
Modern Residential Kitchens
For kitchens where users need more capacity for cookware, trays, and daily washing tasks.
Workstation Sink Programs
For brands that want to combine deeper bowls with accessory ledges, cutting boards, and grids.
Apartment & Project Kitchens
For project kitchens where buyers want stronger practicality without changing the countertop footprint.
Premium Kitchen Collections
For higher-positioned sink programs where custom depth, finish, and accessory matching support a strong story.
Utility and Secondary Kitchen Areas
For utility spaces, laundry areas, and secondary kitchen zones where deeper washing capacity may be useful.
OEM Options for Deep Kitchen Sinks
Matrix can support OEM deep kitchen sink programs based on existing models or custom specifications. Before production, buyers should confirm manufacturing type, target bowl depth, installation method, sink size, radius, drain position, cabinet clearance, accessory set, surface finish, logo, packaging, and order plan.
OEM Kitchen Sink Manufacturing →QC Points Before Shipment
Inspection focuses on details that affect installation, appearance, use, and repeat-order consistency. Bowl depth, drain position, rim design, surface finish, sound pad adhesion, back coating, accessory fit, and packing protection all matter.
- Overall size & Bowl depth check
- Rim flatness & Drain hole check
- Welding/polishing (handmade)
- Formed thickness (pressed)
Packaging for Export & Projects
Deep kitchen sinks need careful packing because deeper bowls may require stronger protection for the rim, sidewalls, bottom, corners, accessories, and surface finish.
