A kitchen sink looks simple until it does not fit the cabinet, blocks the tap, splashes too much, or leaves no counter space for food prep. The best kitchen sink sizes are the ones that fit your base cabinet, suit your washing routine, leave enough countertop space, and work with your tap, plumbing, and kitchen layout.
This guide updates our kitchen sink buying advice with a stronger size-first approach. It covers standard sink widths, bowl depth, single versus double basins, cabinet fit, mounting types, materials, accessories, HDB and condo checks, and what to measure before buying a kitchen sink for an HDB, BTO, condo, resale, or family kitchen.
Quick Answer: What Kitchen Sink Size Should You Choose?
Most kitchen sink sizes fall around 24 to 36 inches wide, or about 61 to 91cm. Compact kitchens often suit a 45 to 60cm single bowl sink, while larger kitchens may use a 75 to 90cm single or double bowl sink. For depth, 6 to 8 inches is easier to reach, while 9 to 12 inches helps with larger pots and splash control.
The clear position: do not choose the biggest sink that fits the countertop. Choose the sink that fits the cabinet, gives enough bowl space, leaves prep space beside it, and does not create awkward bending or splash issues during daily washing.
Kitchen Sink Sizes at a Glance
| Sink Size | Approximate Width | Best For | Watch Out For |
|---|---|---|---|
| Compact single bowl | 45 to 55cm | Small HDB kitchens, rental homes, pantry areas, and light cooking | May feel tight for large woks, trays, and family cookware |
| Standard single bowl | 60 to 75cm | Most everyday kitchens and homeowners who wash larger pots | Needs enough base cabinet width and counter space |
| Large single bowl | 75 to 90cm | Frequent cooking, large cookware, baking trays, and families | Can reduce prep space in compact kitchens |
| Double bowl sink | 75 to 90cm or more | Homes that wash and rinse separately or hand wash many dishes | Each bowl may feel smaller than one large single basin |
| Single bowl with drainer | 75 to 100cm or more | Homes without a dishwasher or with limited drying space | Drainer takes countertop length, so check total footprint |
| Prep sink | 30 to 45cm | Larger kitchens, islands, wet and dry kitchen layouts, and food prep zones | Usually needs extra plumbing planning |
What Kitchen Sink Sizes Mean in Real Use
Sink size is not only the visible bowl width. You need to check the full outer dimension, bowl dimension, cut-out size, cabinet width, bowl depth, tap position, draining board, and under-sink plumbing space.
A sink listed as 75cm wide may have a smaller internal bowl because the rim, drainboard, divider, or mounting edge takes space. A double bowl sink may be wide overall, but each basin may feel too small for a large wok. A deep sink may hide dishes well, but it may also make you bend more.
Before buying, read the product drawing carefully. The number that matters most depends on the installation type. For top-mount sinks, the countertop cut-out and rim size matter. For undermount sinks, bowl support, countertop material, and cabinet space matter more.
Kitchen Sink Width Guide
45 to 55cm sinks
A 45 to 55cm sink suits small kitchens, light cooking, pantries, rental rooms, and compact counters. It is useful when countertop space is more important than washing large cookware.
This size may feel small if you cook daily with woks, large pots, oven trays, steamer baskets, or big cutting boards. It works best when the household has a simple dishwashing routine or uses a dishwasher for heavier loads.
60 to 75cm sinks
A 60 to 75cm sink is a practical starting point for many Singapore homes. It gives enough basin space for daily plates, bowls, cups, pots, and small pans without taking over the whole counter.
This range often works well with standard base cabinets and compact HDB kitchens, but you still need to measure the cabinet and countertop. Do not assume the sink will fit because the kitchen looks wide enough.
75 to 90cm sinks
A 75 to 90cm sink gives more washing room and can suit families, frequent cooks, and homes that hand wash many dishes. This size can also work for large single bowls, double bowls, or sinks with a drainer.
The trade-off is counter space. In a narrow kitchen run, a large sink can leave too little room for chopping, plating, rice cooker use, coffee prep, or appliance placement.
90cm and above
Large sinks above 90cm suit bigger kitchens, island counters, landed homes, spacious condos, or homeowners who want a large sink and drainer setup. They are not automatically better for daily use.
Large sinks need stronger cabinet planning, careful countertop cutting, enough under-sink space, and a proper plumbing layout. Check whether the cabinet can support the sink, especially for heavier materials.
Kitchen Sink Depth Guide
| Depth | Best For | Trade-Off |
|---|---|---|
| 6 to 8 inches | Small kitchens, shorter users, light washing, and easy reach | More splash risk and less room for large pots |
| 8 to 10 inches | Most daily kitchens and balanced household use | Still requires comfortable counter height and tap reach |
| 10 to 12 inches | Large cookware, frequent cooking, and better splash control | Can cause more bending during long washing sessions |
Depth affects comfort as much as capacity. A deeper sink can hide dirty dishes and reduce splashing, but it can strain your back if you wash for long periods. A shallow sink is easier to reach, but may not handle large cookware well.
For most homes, a middle depth is the safest starting point. Choose very deep sinks only if you regularly wash large pots, pans, trays, or baby bottles and you are comfortable reaching the basin floor.
Single Bowl or Double Bowl?
Single bowl sink
A single bowl sink gives one open basin. It is useful for washing large pots, woks, baking trays, and chopping boards. It is also easier to clean because there is no centre divider.
Single bowl sinks suit compact kitchens because they give more usable basin space within a smaller overall footprint. They are a strong choice for HDB and condo kitchens where counter length is limited.
Double bowl sink
A double bowl sink gives two separate washing zones. You can wash on one side and rinse or drain on the other. This can be useful for households that hand wash many dishes or separate food prep from dishwashing.
The trade-off is bowl size. A double bowl sink may not fit large cookware as easily as a large single bowl. If you cook with big woks or trays, check each basin dimension, not only the total sink width.
Sink with draining board
A sink with a draining board can be helpful if you hand wash dishes often and do not have much space for a separate dish rack. It keeps drying items close to the basin and helps water drain back toward the sink.
The trade-off is countertop length. In a small kitchen, a large drainer can reduce your prep area. Choose this only if drying space is a real daily problem.
Match Sink Size to Cabinet Size
The sink must fit the cabinet below it. This is where many buying mistakes happen. The countertop may look wide enough, but the base cabinet, internal supports, plumbing, drawers, doors, and waste trap may limit what can be installed.
Many kitchen base cabinets are around 60cm deep, while sink base modules are often wider to handle plumbing and basin width. A practical sink base may be 80 or 90cm depending on the sink type and under-sink layout. Always check the product drawing and cabinet opening before buying.
For ready-made kitchen cabinets, the sink, hob, and fridge often act as fixed points. Work backwards from these positions before filling the rest of the run with storage modules.
Sink Size by Kitchen Type
| Kitchen Type | Good Sink Starting Point | Why |
|---|---|---|
| Small galley HDB kitchen | 45 to 60cm single bowl | Keeps more counter space for prep and appliances |
| New BTO kitchen | 60 to 75cm single bowl | Balances washing space with compact cabinet planning |
| 4-room or 5-room HDB kitchen | 60 to 80cm single bowl or compact double bowl | Works for daily family cooking if cabinet width allows |
| Condo kitchen | 60 to 75cm single bowl or undermount sink | Needs careful counter, cabinet, and appliance clearance |
| Large dry and wet kitchen | Large main sink plus optional prep sink | Supports heavier cooking and separate prep zones |
| Rental home | Replace like-for-like where possible | Minimises plumbing changes and landlord issues |
Kitchen Sink Mounting Types
Top-mount sink
A top-mount sink, also called a drop-in sink, sits into a cut-out in the countertop. The rim rests on the counter. It is usually more straightforward to install and can work with many countertop materials.
The trade-off is cleaning around the rim. Dirt and water can collect along the edge, so regular wiping matters.
Undermount sink
An undermount sink is installed below the countertop. It gives a cleaner counter line and makes it easier to wipe crumbs and water straight into the sink.
The trade-off is installation. It needs precise fitting, strong support, and a suitable countertop material. Check the installer’s method and warranty before choosing this style.
Farmhouse or apron-front sink
A farmhouse sink has a large, deep basin and visible front panel. It can look warm and traditional, but it needs more cabinet planning and support.
This type is usually less plug-and-play in compact HDB kitchens. Confirm the cabinet cut-out, weight, countertop fit, and delivery before buying.
Integrated sink
An integrated sink is made from the same material as the countertop for a continuous look. It can be easier to wipe down visually, but it is more custom and usually needs professional fabrication.
Repair and replacement can also be more involved because the sink is part of the counter system.
Prep sink
A prep sink is a smaller secondary sink used for washing vegetables, hands, or small tools during food preparation. It suits larger kitchens, islands, wet and dry kitchen layouts, and homes that cook often.
It usually needs extra plumbing planning, so check HDB, condo, and Licensed Plumber requirements before committing.
Kitchen Sink Materials Compared
| Material | Strength | Care Note |
|---|---|---|
| Stainless steel | Durable, practical, stain-resistant, and common for everyday kitchens | Can show scratches and water spots, so choose gauge and finish carefully |
| Porcelain, ceramic, or fireclay | Classic look and good stain resistance | Can chip or crack if heavy cookware is dropped |
| Granite composite | Solid feel, scratch resistance, and many colour options | Can cost more and needs correct cleaning for the finish |
| Cast iron with enamel | Heavy, glossy, and long-lasting when properly supported | Needs strong cabinetry and careful installation due to weight |
| Copper | Warm look and natural patina over time | Needs regular care and can scratch or dent more easily |
Material choice should match how you cook and clean. Stainless steel is the safest everyday choice for many households. Composite and porcelain can look more styled, but they need more careful product-specific care. Heavy sinks need stronger cabinet support.
Faucet and Accessory Fit
Sink size also affects tap choice. A small sink with a very tall tap may splash. A large sink with a short tap may not reach the bowl properly. Check tap height, spout reach, water pressure, and whether the tap hole is pre-drilled.
Also check accessory space. Useful kitchen sink accessories include:
- Sink grid or mat to protect the basin floor
- Dish drainer for hand-washed plates and bowls
- Colander for rinsing vegetables
- Cutting board that sits across the sink
- Sponge holder or soap holder
- Roll-up drying rack
- Strainer basket
- Under-sink organiser for cleaning supplies
Accessories are helpful only if they do not block the sink. Measure the basin, tap position, and nearby counter before buying organisers.
Under-Sink Storage and Plumbing Checks
The area below the sink often has pipes, bottle traps, hoses, water filters, cleaning supplies, bins, and sometimes a dishwasher connection. A large sink can reduce under-sink storage if the bowl is deep or the plumbing takes up more space.
Check these before installation:
- Sink bowl depth below the counter
- Bottle trap position
- Drain outlet position
- Water inlet position
- Dishwasher or washing machine connection, if any
- Space for a water filter or under-sink organiser
- Cabinet shelf position
- Door or drawer clearance
- Access for future repairs
A sink that looks good above the counter should still leave the plumbing accessible below. Do not box everything in so tightly that a simple leak becomes difficult to inspect.
HDB, Condo, and Plumbing Checks
For HDB homes, check current HDB renovation guidelines before replacing, relocating, or changing plumbing around a kitchen sink. Replacing a sink in the same position is different from moving a sink to another wall or changing discharge pipes.
PUB states that regulated water service and sanitary plumbing works must be carried out by Licensed Plumbers, except for listed simple plumbing works. Since sink works can involve sanitary discharge, bottle traps, water fittings, or pipe changes, confirm the scope before hiring anyone.
VERIFY: Before publishing or starting renovation work, confirm current HDB, PUB, condo MCST, and Licensed Plumber requirements for your exact sink replacement, relocation, tap work, pipe work, and cabinet changes.
How to Measure Before Buying a Kitchen Sink
- Measure the countertop length where the sink will sit.
- Measure the base cabinet width below the sink area.
- Check cabinet depth, especially if the sink is deep or has a drainer.
- Measure the current cut-out if replacing an existing sink.
- Check the tap hole position and backsplash clearance.
- Measure the distance to the hob, wall, fridge, and dish-drying area.
- Check under-sink plumbing and bottle trap position.
- Confirm whether the sink is top-mount, undermount, integrated, or custom.
- Check whether the countertop material can support the installation method.
- Ask the installer to confirm cut-out size before any cutting starts.
For replacement sinks, the cut-out is one of the most important measurements. A new sink that is slightly smaller than the existing cut-out may not sit securely. A larger sink may require cutting, support changes, or a new countertop plan.
Common Kitchen Sink Size Mistakes
Buying a sink before choosing the cabinet
The sink and base cabinet must work together. Choose sink size, cabinet width, countertop material, and plumbing position as one decision.
Forgetting bowl depth
Width is easy to notice, but depth affects comfort. A deep sink can be useful, but it may cause bending if the counter is already high or the user is shorter.
Choosing double bowl without checking bowl width
Double bowl sinks look practical, but each bowl may be too small for large cookware. Check internal bowl dimensions before choosing one.
Ignoring tap reach
A tap that does not reach far enough can make the sink awkward to use. A tap that is too tall for a shallow sink may splash more.
Not planning drying space
If you hand wash dishes often, plan where wet plates, bowls, pots, and utensils will dry. This may mean a sink with drainer, roll-up rack, dish rack, or sink organiser.
Forgetting future repair access
Under-sink plumbing needs space. Avoid designing a cabinet so tightly that leaks, traps, or hoses are hard to reach later.
Where to Plan Kitchen Sink Storage and Accessories
Browse kitchen cabinets at Mega Furniture if you are planning the storage around your sink zone. Kitchen cabinets can help organise cookware, pantry items, plates, appliances, and cleaning essentials, but the sink base must be measured carefully around plumbing and bowl depth.
You can also explore sink organisers for sink mats, drainers, sponge holders, and daily washing accessories that help keep the basin area cleaner and easier to use. For wider kitchen planning, browse kitchen organisers, kitchen and dining accessories, kitchen appliances, hobs, cooker hoods, and dishwashers.

Complimentary delivery and professional assembly are available on qualifying Mega Furniture orders. This matters for kitchen cabinets and storage because correct placement, levelling, door alignment, and delivery access affect daily use. Sink fixtures, tap installation, cut-outs, and plumbing works should still be confirmed with the relevant product supplier, contractor, or Licensed Plumber.
A growing share of Mega Furniture's cabinet, dining, storage, and furniture range now comes from its own factories in Batu Pahat, Johor and Foshan, Guangdong, both operational since late 2025. Quality checks happen in-house before pieces ship to Singapore, where delivery and professional assembly are handled locally. It is not the whole range yet, and sink fixtures, taps, plumbing, stone tops, or third-party carpentry details should still be verified by product and supplier, but the programme is expanding through 2028.
Kitchen Sink Sizes FAQs
What are standard kitchen sink sizes?
Standard kitchen sink sizes often range from about 24 to 36 inches wide, or roughly 61 to 91cm. Compact sinks can be around 45 to 55cm wide, while larger single or double bowl sinks can be 75 to 90cm or more.
What kitchen sink size is best for a small HDB kitchen?
A 45 to 60cm single bowl sink is often a practical starting point for a small HDB kitchen. It gives enough washing space for daily use while preserving counter space for food prep and small appliances.
Is a single bowl or double bowl kitchen sink better?
A single bowl sink is better for washing large cookware, woks, trays, and chopping boards. A double bowl sink is better if you like to wash and rinse separately, but each basin may be smaller.
How deep should a kitchen sink be?
A kitchen sink depth of 8 to 10 inches suits many homes. Shallower 6 to 8 inch sinks are easier to reach, while deeper 9 to 12 inch sinks help with larger pots and splash control but may require more bending.
What size cabinet do I need for a kitchen sink?
The cabinet must be wider than the sink bowl and strong enough for the installation type. Sink base cabinets are often around 80 or 90cm for larger sinks, but you should check the exact sink drawing, cabinet width, plumbing, and countertop cut-out.
Can I put a large sink in a small kitchen?
You can, but it may reduce counter space and under-sink storage. In a small kitchen, a balanced sink size is usually better than the largest sink possible.
Is an undermount sink better than a top-mount sink?
An undermount sink gives a cleaner countertop line and easier wiping, but it needs stronger support and careful installation. A top-mount sink is usually simpler to install and can work with more countertop materials.
What kitchen sink material is easiest to maintain?
Stainless steel is one of the easiest everyday materials to maintain. It is durable, practical, and common in busy kitchens, though it can show scratches and water spots over time.
Do I need a sink with a draining board?
A draining board is useful if you hand wash dishes often and need drying space. It may not be necessary if you use a dishwasher, have a separate dish rack, or need more counter space.
What should I measure before buying a kitchen sink?
Measure the countertop length, base cabinet width, cabinet depth, existing cut-out, bowl depth, tap position, backsplash clearance, drain position, water inlet, and nearby appliances before buying.
Do HDB homeowners need approval to replace a kitchen sink?
Requirements depend on the work scope. Replacing a sink in the same position is different from relocating a sink or changing plumbing. Check current HDB guidelines and PUB Licensed Plumber requirements before starting.
Where can I buy kitchen sink organisers in Singapore?
You can browse sink organisers, kitchen organisers, kitchen cabinets, kitchen and dining accessories, and kitchen appliances at Mega Furniture. Measure your sink and counter area before buying organisers so they do not block your washing space.
