Bathroom Pipework Upgrade

A bathroom pipework upgrade replaces ageing or poorly installed pipes behind walls, under floors and around fixtures. It is the best time to do it during a bathroom refurbishment, so everything is routed correctly, sized properly, and pressure tested before surfaces are closed up.

More information

What a bathroom pipework upgrade covers

A pipework upgrade refreshes the hidden plumbing so your new bathroom performs as well as it looks. Depending on the layout and the condition of the existing system, the service can include:

  • Removal or isolation of redundant hot, cold and waste pipe runs
  • New hot and cold feeds to bath, shower, basin, WC and any extras
  • New waste and venting arrangements where needed for good flow
  • Correct pipe sizing to maintain pressure and reduce noise
  • Neat routing, secure fixing and proper access to valves
  • First fix and second fix plumbing to suit your bathroom schedule
  • Connection of sanitaryware and brassware once fitted
  • Leak and flow testing of all water and waste before handover

When this service is the right fit

A pipework upgrade is most relevant when you are refurbishing and any of the following apply:

  • The current pipework is old, undersized or prone to leaks
  • You are moving fixtures and need new supply and waste routes
  • You are fitting a high performance shower or changing to a mixer
  • You want to reduce the risk of hidden leaks after tiling and decorating
  • You are updating a rental property and want dependable, serviceable plumbing

How the work is delivered

The work is usually planned around the refurbishment programme.

  1. Assessment and plan: confirm the new layout, pipe routes, isolation points and any constraints.
  2. First fix: run new hot, cold and waste pipework before walls and floors are closed.
  3. Second fix: connect taps, shower valves, WC, basin and bath once fitted.
  4. Testing and checks: pressure and leak test, confirm waste flow, and check for correct operation.

After completion

You will have a bathroom plumbing setup that is easier to maintain and less likely to cause hidden damage. If anything needs fine tuning after other trades finish, adjustments are typically straightforward because the pipework has been planned with access and isolation in mind.

Frequently Asked Questions

Do I need to upgrade pipework if I am only changing the bathroom suite?
Not always, but it is worth checking the condition, sizing and layout of what is hidden. If the pipework is old, poorly routed, or difficult to isolate, upgrading during the refit can prevent leaks and performance issues later.
How long does a bathroom pipework upgrade take?
It depends on whether the layout is changing and how accessible the runs are. Many jobs are split into first fix and second fix visits to suit the refurbishment schedule.
Does this include both supply pipes and waste pipes?
It can include hot and cold supplies, wastes and traps, and any required adjustments to improve flow. The exact scope is confirmed once the new layout and existing plumbing are reviewed.
Can you coordinate with my bathroom fitter, tiler or builder?
Yes, the pipework is typically programmed around other trades so first fix happens before boarding and tiling, then second fix once fixtures are installed. Clear handover points help avoid delays and rework.
Will the water need to be turned off during the work?
Usually yes for parts of the job, especially when altering feeds or fitting new isolation valves. Where possible, shutdowns are planned and kept short, but full isolation may be required during first fix.
