Bathroom plumbing ranges from a 20-minute shower cartridge swap to a two-week refit. Get scope, day-by-day timeline, and a written quote before work begins — especially for refits where tiling, electrics and plumbing overlap. No call centres, no middlemen — you contact the engineer directly, describe the job, and agree scope and price before booking.

Single-item bathroom plumbing jobs

Showers

• Electric shower faults — unit failure, fuse tripping, weak flow or cold water only. Electric showers are usually replaced as a unit rather than repaired.
• Mixer / thermostatic shower faults — worn cartridge, failed thermostat, scale build-up. Cartridge replacement is often possible; severe scale damage may need full valve replacement.
• Shower pump failure — gravity-fed systems in older Croydon properties often use a pump to boost pressure. Pumps have a limited lifespan and are replaced rather than repaired.
• Shower tray / enclosure leaks — silicone seal failure, cracked tray, or waste leak. Often shows up as staining on the ceiling below.

Basins, baths and toilets

• Basin or bath replacement — typically 2–4 hours if the existing waste and supply positions are re-used. Longer if repositioning.
• Toilet issues — see Toilet Repairs Croydon for cistern and pan-specific work.
• Waste trap blockages — see Blocked Drains Croydon if clearing the trap doesn’t fix it.

Valves and fittings

• Isolating valves — small valves on each fixture’s supply, essential for safe repair work. Replace any that are seized during bigger jobs.
• Flexible tails — often need replacing during tap or toilet changes; cheap parts, easy work.

Bathroom refits — what to expect

A full bathroom refit is a multi-trade project. Plumbing is only part of it; tiling, electrics, extraction fans, flooring and making good all play a role. A typical sequence:

1. Strip out — remove existing sanitaryware, tiles, flooring (day 1)
2. First fix plumbing and electrics — pipework and wiring in place for new layout (days 2–4)
3. Wall preparation and tiling — board, waterproof, tile (days 4–7)
4. Second fix plumbing and electrics — install sanitaryware, taps, shower, lights (days 7–9)
5. Sealing, testing and snagging — silicone, flush-through, leak checks (days 9–10)

Timings vary widely. A small ensuite with no layout change can be done in 5 working days; a family bathroom moving the toilet, changing the shower to a walk-in and retiling can take 2–3 weeks.

Who does what: some engineers handle the whole refit as a project; others do the plumbing only and work alongside a tiler and electrician you’ve booked separately. Clarify this before agreeing the quote — a quote for “bathroom refit plumbing” is not the same as a quote for a “complete bathroom refit.”

Electrics in bathrooms: bathroom electrical work must comply with Part P of the Building Regulations.¹⁰ Some bathroom electrical work is notifiable and must either be carried out by a registered competent person who can self-certify, or notified to Building Control before work begins. Replacements, repairs and maintenance are not generally notifiable. Any engineer quoting for a full refit should confirm who is responsible for electrical compliance and any required notification before work starts.

Shower performance — pressure and flow in Croydon properties

Shower performance depends on two things: the supply (pressure and flow rate) and the shower unit itself.

Mains-fed (high-pressure) system: most newer Croydon properties and modern refits run off the cold mains, producing 2–3+ bar pressure. Any modern shower will work well.

Gravity-fed (low-pressure) system: older properties with a cold water tank in the loft supplying the bathroom may produce only 0.1–0.5 bar at the shower head. Typical issues:

• electric showers work fine (they boost the incoming cold mains)
• mixer showers run weak unless a pump is fitted
• thermostatic showers may not meet their minimum pressure requirement

If your shower runs weakly, check whether you have a pump (usually in the loft or airing cupboard) — if it’s failed, that’s the issue. If there’s no pump and you want stronger flow, a pump installation is typically a 2–4 hour job.

Unvented cylinders: some Croydon properties have unvented hot water cylinders supplying high-pressure hot water throughout. Work on unvented hot water cylinders must be carried out by a competent person with appropriate unvented/G3 competence; annual servicing is commonly required by manufacturers and is good safety practice. Any engineer working on an unvented cylinder should hold a current G3 certificate — ask to see it.

Hard water and bathroom plumbing in Croydon postcodes

Clean-water supply across Croydon is split. Croydon Council confirms Thames Water supplies clean water to the majority of the borough while SES Water (Sutton & East Surrey) provides clean water to the southern part of the borough.⁴ Thames Water confirms hard water can lead to limescale build-up on household appliances and fittings.¹ SES Water publishes postcode-level water hardness reports — southern Croydon postcodes should be checked against the SES Water postcode report.⁵

In bathrooms this shows up as:

• scale on shower heads and aerators (regular descaling helps)
• shower valve cartridges seizing or leaking over time
• limescale marks on glass and chrome
• scale in hot water cylinders, reducing efficiency

Ask your installer about scale-reducing fittings (inline inhibitors, magnetic filters) if you’re doing a full refit — fitting them during installation is far easier than retrofitting later.

Croydon housing stock — practical context for bathroom plumbing

The practical context of a bathroom refit or repair differs widely by Croydon property type. The notes below are general observations to help frame a call to an engineer — your engineer’s site visit will confirm what your specific property actually has.

Pre-1914 Victorian and Edwardian terraces — Thornton Heath CR7, South Norwood SE25, Norbury SW16, Addiscombe CR0, parts of West Croydon and Selhurst SE25. Older terrace stock often has bathrooms in extensions or converted return rooms, with awkward soil pipe routes, original cast-iron waste runs, and shared soil stacks with neighbouring properties. Floor levels and joist directions affect what’s possible in a refit — particularly when moving a toilet or shower. Lead supply pipework pre-1970 is not uncommon and may need attention during a refit.

Inter-war semis and 1930s housing — Purley CR8, Coulsdon CR5, Sanderstead CR2, parts of Shirley CR0 and Selsdon CR2. The semi-detached belt across south Croydon typically has gravity-fed hot water systems with cold water tanks in the loft and cylinders in airing cupboards. Many showers in this stock are weak without a pump; pump replacement is a common bathroom job. Original bathroom layouts often had a separate toilet — combining into a single room is a frequent refit goal.

Post-war estates and tower blocks — Selhurst SE25, New Addington CR0, Shrublands CR0, parts of central Croydon CR0. Council and ex-council estate flats commonly have shared soil stacks and waste runs. For council tenants, repairs go through the council on 020 8726 6101.² For leaseholders, bathroom refits typically require landlord/freeholder permission, particularly where work could affect communal pipework. Check your lease terms before quoting.

Modern flats and town-centre regeneration — East Croydon CR0, town centre CR0, Saffron Square CR0, Ruskin Square CR0. New-build flats around East Croydon typically have mains-fed pressurised systems with unvented hot water cylinders and walk-in showers. Wall-hung sanitaryware and concealed cisterns are common; access panels may be needed for repairs. G3 competence required for unvented cylinder work.

Council tenants in Croydon — bathroom repair route

If you live in a Croydon Council home, bathroom plumbing repairs go through the council, not a private engineer. Full bathroom refits in council properties are handled through the council’s planned maintenance programme.

Call 020 8726 6101 for Croydon Council repairs. The repairs contact centre is open Monday to Friday, 8am to 6pm for routine repairs; emergency repairs can be reported at any time of the day or night.² Non-emergency repairs can also be reported via the council’s online portal.

Do not arrange private refits or major plumbing changes in a council property without written permission.

Private tenants in Croydon — landlord obligations

Bathroom plumbing repairs in a rented property are generally the landlord’s responsibility where the issue falls within the landlord’s repairing obligations. Section 11 of the Landlord and Tenant Act 1985 requires landlords to keep in repair and proper working order the installations for the supply of water and for sanitation (including basins, sinks, baths and sanitary conveniences).⁶ Some bathroom work may fall outside this — for example, bathroom improvements or refits that aren’t repair work, tenant-caused damage, or tenant-owned fittings — and tenancy terms apply.

Report the fault to your landlord or letting agent first, in writing.

Croydon Council advises private tenants that for an urgent repair they should contact their landlord or agent immediately and follow the call up with a letter or email.³

If your landlord does not respond or gives an unreasonable response, contact Croydon Council’s Private Sector Housing Team on 020 8760 5476. The council uses the Housing Health and Safety Rating System to assess the hazards and risks in your home and, if they are serious, may be able to take action to get the landlord to complete work.³
