Replace a sink

⭐ Introduction

Replacing a sink is a common plumbing job in UK homes. You might need to change your sink if it’s damaged, outdated, or you’re upgrading to improve your kitchen or bathroom’s look and functionality. Sometimes, replacements happen during a wider renovation or when the existing sink isn’t practical for your needs.

Whether you have a ceramic sink, stainless steel, or composite material, swapping it out can refresh your space and resolve problems like leaks or blockages.

🔧 What the job involves

Replacing a sink means carefully taking out the old unit and fitting a new one. This includes:

• Disconnecting the water supply and waste pipes.
• Removing the taps (faucets) if they are part of the swap.
• Lifting out the old sink, which might be fitted with sealants or clips.
• Adjusting the cupboard or worktop if needed to fit the new sink size or style.
• Installing the new sink securely—making sure it’s watertight and level.
• Reconnecting all pipework correctly to avoid leaks.
• Testing all connections and taps to ensure proper water flow and drainage.

For some sinks, like undermounted or inset types, there may be additional steps to secure the sink beneath the worktop, which requires some skill to avoid damaging your kitchen units.

📝 Step-by-step from booking to completion

1. Enquiry
   Contact a reputable plumber with details about your current sink and the replacement you want, including measurements if possible.

2. Survey and quote
   The plumber may offer to visit your home to check sizing, pipework, and access before providing a written quote. This helps avoid surprises on the day.

3. Arrange installation date
   Agree on a suitable date and confirm what's included in the job (e.g. waste pipe alterations).

4. Day of works

   • The plumber will protect your floors and work area.
   • Water and waste connections will be isolated and disconnected.
   • The old sink will be carefully removed.
   • Any necessary adjustments to the worktop or cupboard will be done.
   • The new sink and taps will be installed and sealed.

5. Testing and wrap-up
   Water supply is turned back on, and the plumber checks for leaks or drainage issues. The area is cleaned, and you’ll receive any paperwork or guidance on your new sink.

💷 Main costs to expect

• Labour (£80–£150 per hour; typical install 2–4 hours)
• Materials/parts (new sink £100–£400+, taps extra if replaced)
• Waste disposal (some plumbers include, others charge £20–£50 for old sink removal)
• Additional parts (new pipes, seals, clips if needed, £20–£60)
• Certification (usually not needed for just a sink, but check any related plumbing work complies with local regs)

Sample simple job itemisation:

• Labour (3 hours) – £300
• Sink and basic sealing materials – £150
• Waste disposal – £30
• New pipe fittings and seals – £40
• Total estimate: approx. £520 (prices exclude VAT where applicable)

📊 What affects the price

• Sink type and size (large or bespoke sinks cost more)
• Access to plumbing (tight spaces or awkward cupboards add time)
• Complexity of pipework changes needed
• Need for additional cupboard or worktop alterations
• Whether new taps or waste fittings are installed
• Urgency of the job (emergency or out-of-hours visits cost more)
• Location of your property (labour costs vary across UK regions)
• Any remedial works once the sink is removed (e.g., water damage repairs)

⏱ How long does it take?

• Simple like-for-like sink swap: 2 to 3 hours
• Slightly larger or different style requiring minor cupboard adjustments: 3 to 4 hours
• Complex installations with new pipework or tap replacements: 4 to 6 hours or more

Unexpected complications, such as corroded pipework or sealed-in units, can extend the job.

🏠 Can you DIY it?

If you have basic plumbing skills and tools, you may manage a simple sink replacement, especially if it’s a standard inset sink with the same dimensions and taps. However, not everyone has the confidence or experience to:

• Safely isolate and reconnect water supplies
• Work with waste pipe fittings (including traps) to avoid leaks or blockages
• Modify cupboards or worktops without damage

Incorrect installation can lead to leaks, water damage, or failed fittings. Plumbers are registered professionals who understand UK plumbing standards and regulations. For anything other than a straightforward swap, or if you have gas or electrical appliances nearby, it’s wise to hire a pro.

💰 Typical UK price range

A standard domestic sink replacement typically costs between £350 and £700. This is an approximate range, including parts and labour but excluding VAT. Prices vary widely depending on the work involved and location.

✅ Handy tips before you start

• Measure your existing sink dimensions and note tap types before contacting tradespeople.
• Choose your replacement sink with installation practicality in mind (size, style, material).
• Clear out under-sink cupboards and worktops for easy access.
• Ask the plumber if removal and disposal of your old sink is included so you can plan accordingly.
• Keep all paperwork, including quotes and invoices, for warranty and future reference.
• Check whether your replacement requires changes to other parts of your plumbing system, and if so, ensure any work complies with Building Regulations.
• After installation, monitor the sink and pipework for leaks during the first few days and report any issues promptly.

By preparing well and using a qualified plumber, you can ensure your new sink is installed safely and functions perfectly for years to come.
