Everything You Need to Know Before Buying a Kitchen Sink
A kitchen sink is one of the hardest-working features in your home. Whether you're planning a full kitchen renovation, replacing an existing sink or designing your dream kitchen from scratch, choosing the right sink can make everyday life easier for years to come.
With hundreds of styles, materials and installation options available, it's easy to feel overwhelmed. Should you choose stainless steel or granite composite? Is a 1.5 bowl sink really worth it? Will an undermount sink work with your worktop?
At The Tap Specialist, we've helped thousands of homeowners, kitchen designers, installers and trade professionals choose the right kitchen sink. In this guide, we'll explain everything you need to know so you can buy with confidence.

How to Choose the Right Kitchen Sink
Before looking at colours or brands, ask yourself these questions:
✔ How much space do you have?
✔ What size cabinet are you fitting the sink into?
✔ Do you wash large pans regularly?
✔ Do you have a dishwasher?
✔ Are you fitting a boiling water tap?
✔ Would a second bowl make food preparation easier?
✔ What type of worktop do you have?
Your answers will determine which sink is best suited to your kitchen.
Step 1 – Choose Your Installation Type
Top-Mount (Inset) Kitchen Sinks
Top-mount sinks, also known as inset or drop-in sinks, are one of the most versatile installation options. The sink sits on top of the worktop with a visible rim around the edge.
Advantages
-
Suitable for almost every worktop material
-
Easier and more cost-effective to install
-
Excellent choice when replacing an existing sink
-
Wide choice of sizes and styles
Considerations
The visible rim can collect crumbs and water, requiring a little more cleaning than an undermount sink.
Undermount Kitchen Sinks
Undermount sinks are installed beneath the worktop, creating a sleek, contemporary finish.
This style has become increasingly popular in premium kitchens because it allows crumbs and water to be wiped directly into the bowl without catching on a raised edge.
They work particularly well with:
-
Quartz
-
Granite
-
Solid surface
-
Porcelain
Advantages
✔ Modern appearance
✔ Easy to clean
✔ Maximises worktop space
✔ Perfect for premium kitchens
Considerations
Undermount sinks require a solid worktop and professional installation.
Flush-Mount Kitchen Sinks
Flush-mounted sinks sit perfectly level with the worktop, creating an elegant, minimalist appearance.
They're popular in contemporary kitchens where design is just as important as practicality.
Step 2 – Choose the Right Number of Bowls
One of the biggest decisions you'll make is how many bowls your sink should have.
Single Bowl
Perfect for:
-
Smaller kitchens
-
Apartments
-
Utility rooms
-
Customers who prefer one large washing area
Pros
✔ Large uninterrupted space
✔ Ideal for roasting trays
✔ Easier to clean
1.5 Bowl
If there's one style we recommend most often, it's the 1.5 bowl.
The larger bowl is used for washing dishes and cookware, while the smaller bowl is ideal for rinsing vegetables, draining pasta, emptying drinks or separating food preparation from washing up.
It's a fantastic choice for busy households and one of the most popular configurations across our premium sink ranges.
Double Bowl
Ideal for:
-
Large families
-
Keen cooks
-
Entertaining
-
Traditional kitchen layouts
A double bowl sink gives you maximum flexibility, allowing you to wash, rinse and prepare food simultaneously.
Step 3 – Which Kitchen Sink Material is Best?
Stainless Steel
Stainless steel remains one of the UK's most popular choices, and for good reason.
High-quality stainless steel sinks are:
-
Durable
-
Hygienic
-
Heat resistant
-
Easy to maintain
-
Timeless in appearance
Premium stainless steel sinks also feature sound-deadening technology to reduce noise from running water and washing up.
Best for:
✔ Contemporary kitchens
✔ Busy family homes
✔ Professional-style kitchens
Granite Composite
Granite composite sinks combine natural stone particles with high-performance resins to create a durable, attractive finish.
They're resistant to:
-
Scratches
-
Stains
-
Heat
-
Fading
Available in colours such as black, white, grey and anthracite, they are an excellent option for modern kitchens looking for a statement finish.
Fireclay & Ceramic
Ceramic and fireclay sinks offer timeless character and exceptional durability.
They work particularly well in:
-
Traditional kitchens
-
Shaker kitchens
-
Farmhouse-style homes
Their smooth glazed finish is easy to wipe clean and resistant to staining.
Step 4 – Choosing the Right Cabinet Size
One of the most common mistakes is choosing a sink that doesn't fit your base cabinet.
Before ordering, always check:
-
Minimum cabinet width
-
Overall sink dimensions
-
Bowl depth
-
Installation requirements
Many premium sinks require:
-
500mm cabinet
-
600mm cabinet
-
800mm cabinet
-
900mm cabinet
If you're unsure, our team is always happy to help you choose the right model.
Step 5 – Which Kitchen Sink Brand Should You Choose?
Rather than one brand being "best", each offers different strengths.
| Brand | Best For |
|---|---|
| Franke | Premium stainless steel and granite composite sinks, innovative accessories and outstanding build quality. |
| Blanco | German engineering with market-leading granite composite technology and elegant contemporary designs. |
| Alveus | Modern European styling, practical features and excellent value across stainless steel and composite ranges. |
| Abode | Stylish designs with a wide choice of colours and contemporary finishes for modern kitchens. |
| Ellsi | Design-led sinks offering excellent value for contemporary homes. |
| Reginox | Reliable stainless steel sinks with practical configurations and everyday durability. |

Step 6 – Don't Forget the Accessories
A kitchen sink isn't just the bowl itself. Choosing the right accessories can improve functionality, save space and ensure a trouble-free installation.
Consider adding:
-
Colanders
-
Sink grids
- Accessories Sets
For many premium sinks, using genuine manufacturer accessories provides the best fit and performance.
Common Mistakes to Avoid
Even experienced renovators can make costly mistakes. Before placing your order, double-check these points:
-
Choosing a sink that's too large for your cabinet.
-
Selecting the wrong installation type for your worktop.
-
Forgetting to order the correct waste or plumbing kit.
-
Not considering bowl depth if you regularly wash large cookware.
-
Focusing on appearance without thinking about day-to-day practicality.
-
Assuming every sink is compatible with every tap—especially if you're planning to install a boiling water tap or filter tap.
