The sink can make or break the look of your kitchen. If yours is beginning to look tired, you might want to replace it. But how much will it cost?

The average cost of replacing a kitchen sink in the same location is £115, but the final cost will vary depending on a few factors. We’ll explain everything in this guide.

How much do plumbers charge to replace a kitchen sink?

The average cost to replace a kitchen sink in the UK ranges from £100 to £250, depending on whether you’re replacing like-for-like, whether it’s in a new location, and other factors.

Here’s a general breakdown of costs:

If you're also updating your kitchen taps or installing a waste disposal unit, expect to pay more due to the extra time and fittings required.

Factors affecting the cost of replacing your kitchen sink

The cost of replacing a kitchen sink isn’t just about the price of the new unit. Several factors can influence how much you’ll pay for the full job:

• Type and size of the sink: Larger or heavier sinks such as Belfast or stone composite models may cost more to install than lightweight stainless steel ones. Undermount sinks usually require more labour than drop-in styles, as they need to be sealed from underneath.
• Worktop compatibility: If your new sink doesn’t match the size or shape of the old one, your worktop may need to be cut or modified. Solid surfaces like granite or quartz can be costly to alter, sometimes requiring a professional kitchen fitter.
• Additional fittings: If you’re also replacing the taps, adding a boiling water tap or fitting a waste disposal unit, the extra plumbing work will increase labour time and cost.
• Plumbing changes: If your plumbing is old, or you want to fit your new kitchen sink in a different location, it’ll cost more to have more pipework fitted.
• Accessibility: If your sink is in a difficult-to-access area, for example, in a tight corner or behind built-in appliances, the job may take longer which will push up labour costs.
• Disposal of the old sink: Some plumbers will remove and dispose of your old sink for free, while others may charge an additional fee for waste disposal.
• Your location: Plumber rates vary by region. You’ll usually pay more for kitchen sink replacement in London and the south east and less in northern parts of the UK.

Kitchen sink types

Choosing the right type of sink can have a big impact on installation costs as well as the functionality and look of your kitchen. Here are the main types to choose from:

• Inset/drop-in sink: The most common type of sink, designed to drop into a pre-cut hole in the worktop. Easy to install and replace. Ideal for most kitchen worktops.
• Undermount sink: Mounted beneath the worktop, leaving the counter edge exposed. Offers a sleek, modern look but typically requires solid surface worktops (like granite or quartz) and more skilled fitting to ensure there’s no water damage.
• Belfast/butler sink: A deep, ceramic apron-front sink that’s typically installed into a specially-designed unit. Stylish and practical, but heavy and often more complex to install due to size and support requirements.
• Top-mount composite sink: Made from materials like granite or quartz composite. Durable and available in various colours. Installation is similar to stainless steel drop-ins, but weight and size can vary.
• Corner sink: Designed to fit into kitchen corners, often used in compact or L-shaped kitchens. May involve custom fitting or additional plumbing work.
• Double-bowl sink: Great for multitasking, with separate sections for washing and rinsing. Takes up more space and may require changes to existing plumbing.

Each type has its pros and cons depending on your kitchen layout, worktop material and how you tend to use your sink. Speak to a plumber to check which options suit your space best.

How often should you replace your kitchen sink?

There’s no set timeline for replacing a kitchen sink - it often depends on condition rather than age. A quality stainless steel sink can last 15-30 years, while ceramic and composite sinks may last even longer if looked after properly.

You might want to consider replacing your kitchen sink if:

• It has cracks, chips or rust
• There are persistent leaks or signs of corrosion
• It's become stained or difficult to clean
• You’re upgrading your kitchen or worktops

Replacing your sink during a kitchen refresh is a cost-effective way to modernise the space without committing to a full new fitted kitchen.

How long should it take a plumber to replace a kitchen sink?

For a straightforward like-for-like swap, a professional plumber should be able to remove the old unit and install the new one in around 1.5 to 3 hours. More complex jobs, such as fitting a different size or shape, moving plumbing, or installing new taps alongside your sink, may take half a day or longer.

If your worktop needs to be cut or altered to accommodate the new sink, this could add extra time or require a joiner or kitchen fitter’s help.

Can I replace my kitchen sink without replacing the countertops?

Yes - in most cases, you can replace your kitchen sink without touching the worktops, provided the new sink is the same size and shape as the old one. This is especially true for inset or drop-in sinks, which are designed to sit in a cut-out section of the countertop.

If you're changing the style of sink (for example, from drop-in to undermount) or going for a significantly different size, your worktops may need to be cut or replaced. Always double-check sink dimensions before buying to ensure compatibility with your existing counter.

Can I move my kitchen sink to a different area in the kitchen?

If you’re planning on a kitchen refresh and the current location of the sink doesn’t make sense, then there’s no reason why you can’t move your sink to a better location.

Before you call in the plumber, decide on the location you want it moved to, as this will affect the price. Moving slightly from where it is means that current flexi hoses can be adapted using the same drain and waste pipes, but moving across the kitchen or to an island will mean needing to reroute a water supply and a waste pipe to connect to the main waste pipe. Usually, this will be run under floorboards or behind kitchen cabinets.

My kitchen sink is leaking - can it be repaired?

In some situations, when a kitchen sink is leaking, it may be a simple case of tightening a nut or replacing a deteriorated washer. Often, leaks under the sink are caused by the hand-tightened joints on the PVC that have loosened over time and may just need re-tightening.

In the worst case, if your sink has a pinhole, check with the plumber if it is a hole that can be patched to avoid having to replace your kitchen sink. Plumbers' putty is a great fix, especially when the drain needs resealing.

Can you replace a kitchen sink yourself?

You can replace a kitchen sink yourself if you're confident with plumbing and have the right tools, especially if it’s a like-for-like replacement. You’ll need to:

1. Turn off the water supply
2. Disconnect the plumbing and remove the old sink
3. Fit and seal the new sink in place
4. Reconnect the water supply and waste pipes
5. Check for leaks

However, things can get tricky if the pipework doesn’t align or if the sealant isn’t applied correctly. If you're unsure or the job involves significant plumbing adjustments or electrical connections, it’s best to call in a professional plumber to avoid water damage and ensure that the installation is safe.
