Labour Costs and Time Frames

A standard plumber will normally charge £75 to £150 to replace a kitchen sink in around 3 to 4 hours, although this will depend on how easy the sink is to install and if any cutting or pipework is needed.

Cost Affecting Factors of Replacing a Kitchen Sink

There are several cost factors you need to consider when having a new kitchen sink installed; for instance, you need to decide on the size and type of sink you want.

If you have a low budget, you need to look at the price of a kitchen sink, and you may want to opt for a single bowl stainless steel sink which normally ranges from £100 to £360 for materials and labour.

However, if you are looking for something more luxurious, you could consider a cast iron double basin sink which costs around £730 to £1840 to install.

You may also need to consider additional costs such as extra plumbing work which may be required if you are moving the sink to a different area of the kitchen.

This should cost around £600 to £1200 with the final price depending on how easy it is to access the installation area and how long the job will take.

Your location will also determine the final price, as plumbers in areas such as London may charge up £500 to install a new kitchen sink, while tradesmen in northern areas only charge around £400.

What Does Installing a Kitchen Sink Entail?

Replacing a sink is not a difficult job for a competent kitchen fitter or plumber and usually involves the following steps:

  1. Sink Assembly

The first thing an installer will do is assemble the sink on-site which involves fitting the waste outlet and overflow, as well as ensuring that all the seals are installed correctly, so there is no chance of a leak.

The fixing clips should also be attached to the sink at this point along with your new taps.

  1. Cut off the Water and Waste Supply

The next step involves turning off the hot and cold water supply under the sink or at the mains.

They will then double-check the water is off by testing the taps in your home.

Once the water is off, they will disconnect the waste connection by unscrewing the plastic pipes underneath the sink.

  1. Old Sink Removal

Once everything is turned off and disconnected, they will then remove the old sink by first removing the taps with the use of a wrench.

Once the taps are off, the sink clips can then be loosened and then cut through any sealant to lift the sink up completely.

  1. Altering the Worktop

If your new sink does not fit properly, then the contractor may have to cut into the worktop using a jigsaw to ensure the sink slots in perfectly.

They will take great care when doing this to avoid damaging your worktop and should clean the area once they are finished cutting.

  1. New Sink Installation

Once the worktop is prepared, the plumber will then fit the sink, making sure that the waste pipes are lined up properly.

When they are sure that the sink is secure, they will then attach sink retaining clips to secure it in place.

They will then attach the original or new taps to the installation, making sure to follow the manufacturer's instructions.

  1. Leak Testing

Before connecting the waste pipe and turning the water back, the plumber will test the taps to make sure there are no leaks.

To do this, they will place a bucket underneath the sink before turning on the water and running the cold tap.

If there any leaks at this point they will fix them quickly by turning the water off and fixing the joint.

  1. Connecting Plumbing and Pipework

Once all diagnostics are complete, the tradesman will then re-fit the waste pipework while checking that all seals are still in good condition.

The water should then stay on to check for additional leaks after applying the waste plugs which will be tested by filling up the sink and releasing it.

DIY Install Kitchen Sink

If attempting to do this job as a DIY project, there are a number of potential pitfalls, the most serious of which is to make a mistake measuring the new sink and cut a hole too large in the worktop, or if ordering a new worktop from the manufacturer to get one with a hole that is too big for the sink.

There is not much that can be done about this, except buy a completely new worktop.

While installing a new kitchen sink with new plumbing should be left to the professionals, a simple replacement is possible for most DIY enthusiasts.

To do this, you will need the following tools:

  • Utility knife (£1 to £18)
  • Pipe wrench (£15 to £85)
  • Screwdriver (£2 to £100)
  • Silicone sealant (£3 to £10)
  • Eye protection (£1 to £40)

By installing a kitchen yourself, you could save around £75 to £150, as this is the typical labour cost that professionals charge.

However, you may want to hire a plumber to check over your installation to ensure that it is fitted safely and properly to avoid leaks and other issues later on.

Choosing a Kitchen Sink

When choosing a new kitchen sink, you should consider the cost, functionality and aesthetics.

Each should be considered carefully when selecting your sink material as there will no doubt be some sort of compromise to be made along the way.

The material of your sink is up to you – it may depend on your budget or the type of look that you want to create in your kitchen.

Before choosing, you should really weigh up the pros and cons to decide which of the following options is best for you.

Ceramic Kitchen Sink Cost

Ceramic sinks are made of a mixture of fillers, clays and fluxed that are blended together to create a durable material that works well with most kitchen interiors.

You should expect to pay around £200 to £730 for a brand new ceramic sink for your kitchen.

The main advantage of choosing a ceramic sink is its extreme robustness which resists excess heat and chemicals that may ruin less durable sink materials.

Ceramic sinks are also low-maintenance and only require some water and all-purpose cleaner to keep it looking pristine.

They are also very easy to install due to their seamless design which is normally available in a variety of colours and sizes.

The downsides of ceramic kitchen sinks are that they are susceptible to cracking and chipping, which can also cause discolouration.

It is also not the best option if you are looking for an eco-friendly installation as manufacturing ceramic wastes a significant amount of energy in comparison to more sustainable sink materials.

Stainless Steel Kitchen Sink Cost

Stainless steel sinks are made up of iron-based materials which makes it one of the favourable reasonably priced sink options with prices ranging from £30 to £700.

Stainless steel sinks are one of the most durable materials which are resistant against chipping, cracking or peeling.

They are also not susceptible to stains due to their extensive thickness and ability to withstand dents.

Steel kitchen sink

Despite stainless steels durability against corrosion, when in contact with abrasive acids, there is the issue of rust.

Another problem with stainless steel sinks is that they scratch easily and show watermarks.

Granite Composite Kitchen Sink Cost

Granite composite sinks are becoming increasingly popular due to the high-quality mixture of granite stone and acrylic resins used to construct kitchen sinks—prices for sink material range from £120 to £1000.

This high-end sink option will offer your kitchen and unique and aesthetically-pleasing design that is long-lasting and can be adapted to fit any kitchen interior. It is also highly resistant to heat, scratches and stains.

The issue with granite composite kitchen sinks is they can be very expensive and aren't necessarily bulletproof either, despite popular belief.

They also need to be sealed at least once a year to prevent damage.

Cast Iron Kitchen Sink Cost

Cast iron sinks are made of iron alloy with a porcelain enamel coating which makes it one of the most durable kitchen sinks on the market.

The average cost of a cast iron sink is around £380 to £1690.

In comparison to solid surfaces like stainless steel, cast iron is much more robust, which means they will not crack or dent even when exposed to extensive damage.

Cast iron kitchen sink

Cast iron sinks are also very easy to clean due to their smooth and non-porous surface, which is highly resistant to stains.

While cast iron is a durable material, the porcelain coating may be susceptible to wear and tear if it is knocked hard.

You also need to be careful when cleaning it, as abrasive cleaners can scratch the surface.

Fireclay Kitchen Sink Cost

Fireclay sinks are made using a fusion of clay and glaze which forms at temperatures up to 1600 degrees.

Fireclay sinks tend to cost around £140 to £1090.

Similar to cast iron sinks, fireclay is a non-porous material which is highly resistant to acids, alkalis and scratches.

It is also much more hard-wearing than other sink materials as it is hardened under extremely hot conditions.

Due to its extensive hardness and durability, you need to be extra careful when washing the dishes as dropping them could lead to them breaking.

You may also have to pay extra during installation to ensure that the weight of the sink is held up by durable support.

Copper Kitchen Sink Cost

Copper sinks are one of the most unique choices available which also offer extensive durability due to it being made in exceedingly hot temperatures. You should expect to pay around £270 to £1700 for a copper kitchen sink.

The main advantage of choosing a copper sink is that the material is antimicrobial, which means it prevents microorganisms from growing, which makes it one of the most hygienic kitchen sinks. They are also highly resistant to rust and corrosion.

Copper kitchen sink

In comparison to other sink materials, it is more high maintenance as it needs to be cleaned regularly to avoid staining. It is also extremely sensitive to excessive heat and abrasive cleaning agents which can cause the copper to discolour.

Single Basin Kitchen Sink Cost

A single basin sink is one of the most popular options for the majority of kitchens due to its simple design with no dividers.

Single basins usually cost around £30 to £180.

The main benefit of single-bowl sinks is that they are ideal for smaller kitchens which have limited counter space.

They also have a lot more room for washing dishes, unlike double basins which tend to have two smaller sections.

If you just have a sink without a dishwasher, then a single basin does make it a lot harder to clean your dishes as they will all be packed in one space.

Double Basin Kitchen Sink Cost

A double basin features two bowls in one compact unit, which can be the same size, although some models have one section larger than the other.

Double-bowl sinks tend to cost around £150 to £2300.

Double basins are ideal for homeowners who tend to cook a lot as they can use one side for dirty dishes and the other for food prep.

This way, you are not mixing dirty water with fresh food and creating a more hygienic kitchen space.

The downside of opting for a double-bowl sink is that it tends to take up a significant amount of under-counter space which can be used to store all your cooking or cleaning equipment.

It also provides less space for washing up large items such as pans due to the divider getting in the way.

For everyday cleaning, you should simply rinse your composite sink with water and use a lint-free cloth to remove any dirt or debris from the sink's surface.
For more stubborn stains, you can use any household cleaner, although try to avoid using acidic products as this can weaken the composite surface.

You can also use a nylon scrub brush and some dish soap to remove food stains or for limescale staining and water stains, you should use diluted vinegar to get rid of the marks, making sure to rinse the sink after you are done.
To ensure your new sink is the right fit, you will need to measure your existing sink with a straightedge ruler.
You should start measuring at the edge of the sink near the counter, then record the length of the sink by measuring the left edge to the right edge. To work out the width, you should place your ruler at the back of the sink and line it across to the front edge.

Then finally, you should measure the depth of your basin by putting the ruler across the top of the sink, then use a tape measure to measure the deepest part of the sink up to the bottom line of the ruler.

If you have an undermount sink, you should remember to measure the height of the basin from the sink to the countertop.
There are various ways to unclog your sink, although one of the easiest and cheapest options is to simply use salt and boiling water from a kettle.
Before pouring it, you should try to remove as much water from your sink using a cup. After pouring the salt and boiling water, you should wait a while to see if the clogged water moves.

If the above method does not work, you can try again or pour a mixture of baking soda and salt down the drain. You should leave this for several hours before checking to see if it has shifted the blockage and if not repeat the process.

If none of the above works, then you may need to hire a plumber to solve the issue with an auger which will involve disconnecting the drainpipe and P-trap before inserting the auger into the pipe.
This should dislodge whatever is causing the blockage quickly, although it may be a more expensive option.
Popular in the USA for many years, now becoming more so in the UK, a variety of kitchen waste disposal systems are now available in the UK designed to fit into the kitchen sink.
These new waste disposal systems are much quieter and more efficient than their predecessors. Modern features include two-stage grinding technology, which helps to reduce the amount of waste going to landfill.

It is estimated that at least 20% of household waste is food waste that could be ground up and discreetly washed away with no smells or dirty bins.
Modern waste disposal units are incredibly safe to use, most don't have a blade and if they jam the grinder system reverses and switches off to allow you to remove anything that was put in the waste by mistake.

Most modern sinks can accommodate a waste disposal unit with a 90mm outlet. Failing that, adapters can be bought for sinks to match most units, in fact, higher quality waste disposal units come with adapters to fit all popular sinks.

How to Find & Hire a Kitchen Sink Installer

To ensure that your kitchen sink is installed properly, you should consider hiring a professional plumber or kitchen sink installer who both charge around £75 to £150.
