Installing or replacing a bath is a common bathroom plumbing job. In many cases the work is straightforward when the existing pipework, waste connection, and access around the bath are in good condition. The time required usually depends on the type of bath, access to pipework, and whether panels, taps, or waste fittings need adjusting or replacing.
Below is a general guide to labour costs for bath installation and replacement.
Bath Replacement
Removing an existing bath and installing a new one using the existing pipework and waste connection is usually a manageable job when access is good.
Typical labour cost: £280 — £480
Time: around 3–5 hours
New Bath Installation
Installing a bath where pipework needs minor adjustment or repositioning may take longer depending on the layout of the bathroom.
Typical labour cost: £350 — £550
Time: around 4–6 hours
Bath Panel Installation or Replacement
Installing or replacing a bath panel is normally a quick job when the bath is already fitted securely.
Typical labour cost: £70 — £140
Time: around 30–60 minutes
Bath Waste & Overflow Replacement
Replacing the bath waste, overflow, or trap usually requires access under or behind the bath and may involve removing the panel.
Typical labour cost: £90 — £160
Time: around 1 hour
When costs can vary
Labour costs can change depending on the condition of the existing plumbing and accessibility of the bath installation. Additional time may be required if:
pipework needs adjusting
the waste connection needs replacing

the bath panel needs modifying
access under the bath is limited
All prices shown are labour-only estimates intended as a general guide. The final cost is confirmed after seeing the job and checking the existing installation.
