Replace a shower (like for like)

Trade: Plumber

⭐ Introduction

Replacing a shower “like for like” means removing your existing shower unit and installing a new one in the same spot with similar specifications. You might need this if your current shower is old, faulty, leaking, or simply outdated. Sometimes homeowners want better performance, improved controls, or a more modern design without changing the plumbing or layout.

This job is quite common in UK homes and can refresh your bathroom without extensive renovation. Most often, it involves swapping showers of the same type – for example, a mixer or electric shower replaced by the same. This keeps disruption and costs to a minimum.

It’s important to use a qualified plumber for the work, who understands relevant UK regulations to ensure safety and compliance.

🔧 What the job involves

Replacing a shower like for like generally includes:

Removing the old shower unit carefully without damaging existing plumbing.
Checking the condition of pipework and valves behind the shower.
Installing the new shower, matching the existing connections for water supply and drainage.
Testing everything to ensure it works correctly and there are no leaks.
Cleaning up any mess created during the work.

If your shower is electric, your installer will check the electrical connections too, following Part P of the Building Regulations for electrical safety in domestic premises.

The main aim is to carry out the replacement quickly and with minimal disruption, keeping the shower’s position and water pressures the same as before.

📝 Step-by-step from booking to completion

Enquiry: Contact a reputable local plumber or bathroom specialist. Explain you want a like-for-like shower replacement and provide details or photos of your current shower.
Survey and quote: The plumber will visit your home to check your existing shower and plumbing. They’ll assess requirements and give you a written quote for labour, parts, and any additional work.
Book the work: Agree on a date that suits you. Confirm any access needs or preparations.
Day of works: The plumber will switch off water and electricity (for electric showers), remove the old shower, prepare fittings, and install the new unit.
Testing: They will test all functions, water pressure, and check for leaks.
Clean up: The work area is tidied, and waste materials disposed of responsibly.
Completion and paperwork: You’ll receive any relevant guarantees and potentially a certificate of compliance, especially if electrical work was involved.

💷 Main costs to expect

Labour: Usually charged per hour or as a fixed price. For a straightforward replacement, expect 2–4 hours of work.
Materials and parts: Price of the new shower unit plus fittings like valves, seals, and possibly new drill-proof wall fixings.
Disposal: Removal and safe disposal of the old shower unit and packaging.
Certification: If the shower is electric, certification under Part P electrical installation standards may be needed.
Extras: Any unexpected plumbing repairs or upgrades such as renewing pipework or upgrading isolating valves.

Example cost breakdown:

Labour: £120–£200
Shower unit: £150–£400 (brand/model dependent)
Parts and consumables: £30–£70
Disposal charge: £20–£40
Certification (electric shower): £50–£80

📊 What affects the price

Access to the shower: tight spaces or difficult wall materials can increase labour.
Complexity of plumbing or wiring: old or damaged pipework may need replacement.
Type of shower being installed (mixer, electric, digital).
Requirement for electrical safety certification (Part P).
Whether any building regulations or water regulations apply.
Location in the UK and local labour rates.
How urgently you need the work done.
Removal of old tiles or shower enclosure, if included.

⏱ How long does it take?

Straight swap: 2 to 4 hours, assuming the existing plumbing is in good condition and no adjustments to wiring or pipework are needed.
More complex replacement: Up to a full day if pipework needs repair, walls must be opened, or new electrical connections are required.
In general, most like-for-like shower replacements are completed within a single day.

🏠 Can you DIY it?

It is possible for experienced DIYers to replace a non-electric mixer shower or a simple mixer valve, provided you have the tools and plumbing skills.

However, there are important safety and legal considerations:

Electric showers must be installed by a Gas Safe or Part P registered electrician/plumber, to ensure electrical connections are correct and safe.
Any work affecting mains water supply must comply with UK water regulations.
Incorrect fitting may cause leaks, water damage, or electrical hazards.
Professional installation ensures your warranty is valid and the work is certified.

If you lack confidence in plumbing or electrical work, hiring a professional plumber is safest.

💰 Typical UK price range

For a like-for-like shower replacement, expect to pay roughly £350 to £800 including parts, labour, and VAT (currently 20%).

This is a general estimate. The price can vary based on shower model, installation complexity and your location in the UK.

✅ Handy tips before you start

Clear the bathroom area and ensure easy access to the work zone.
Check that your water pressure and temperature controls match the new shower specifications.
Ask your installer about guarantees and aftercare instructions.
Keep all paperwork, including invoices and compliance certificates, for future maintenance or if you sell your home.
Consider having a plumber inspect your pipework periodically to avoid leaks or damage.
If you’re installing an electric shower, check that the smoke alarms in your home are compliant and tested, as electrical bathroom updates sometimes prompt safety checks.

Replacing your shower like for like is a practical way to refresh your bathroom without major upheaval. With the right help, it can be hassle-free and safe, giving you years of reliable use.
