What a bathroom install involves — and getting the shower right
Most of a bathroom is the part you stop seeing once it’s finished: the hot and cold supplies to each fitting, the waste pipes with the right falls and trap seals, and the connection to the soil stack for the WC. Get those wrong and you get smells, slow drainage or a leak into the structure; get them right and the visible suite is the easy part.
The decision that catches people out is the shower, because the right type depends on your water system:
- Gravity-fed system (a cold tank in the loft feeding a hot cylinder) gives low pressure, so a mixer shower often needs a pump to feel powerful.
- Combi boiler runs at mains pressure with no tank — you can’t fit a pump, so you choose a shower rated for mains pressure.
- Unvented (pressurised) cylinder gives strong mains-pressure hot water and suits most mixer showers without a pump.
- Electric shower heats its own water from the cold mains, so it works regardless of the hot-water system — useful where hot-water flow is limited.
A plumber will match the shower to the system rather than the other way round. On safety, thermostatic shower and bath valves hold a steady temperature and guard against scalding — and in a hard-water area like London, where Thames Water classes all supplies as hard, scale on shower cartridges and valves is a routine cause of failure over time.2
Bathrooms in Hackney flats: soil stacks, the flat below and the rules
Installing a bathroom in Hackney is shaped by the borough’s housing and a few rules worth knowing.
Flats, soil stacks and the flat below. With Hackney’s housing strategy evidence recording 83.8% of dwellings as flats,5 most bathroom work means connecting into a shared soil stack and accepting that anything that leaks goes into someone else’s ceiling. That puts a premium on sound waste connections, proper trap seals and waterproofing (tanking) under the tiling — and, in a managed block, on checking what the lease and freeholder allow before moving anything.
The 48°C rule — and when it applies. Building Regulations require the hot water to a fixed bath to be limited to 48°C to prevent scalding, normally via a thermostatic mixing valve — but the Government’s Approved Document G guidance is clear this applies to baths in new homes (including those created by a change of use), not to a bath you replace in an existing home — though it’s still worth considering, especially with very young or older household members.1 Separately, altering drainage can be notifiable building work, and bathroom electrics — an electric shower, an extractor fan — are a job for a qualified electrician.
Period versus new-build. The stock pulls in two directions. Conservation-area period homes such as those around the 1830s De Beauvoir Square6 often have a single bathroom in a tight space and original soil pipes, and any change to external soil or vent pipework can need conservation consent. The new flats of regeneration estates like the Hackney Council and Berkeley Homes scheme at Woodberry Down7 tend to have en-suites and modern pressurised systems, so the work is more often a like-for-like upgrade.
Who’s responsible. If you rent privately, the bath, basin and hot-water installations are the landlord’s to keep in repair under section 11 of the Landlord and Tenant Act 1985;3 tenants don’t usually refit. Council tenants should report bathroom repairs to Hackney Council on 020 8356 3691.4
Find a verified bathroom plumber by district
What a bathroom job involves changes with Hackney’s building stock.
- Clapton, Stoke Newington & De Beauvoir (E5 / N16 / N1). Victorian and period homes, often with a single bathroom in a small room and original soil pipes; in the De Beauvoir conservation area6 changes to external soil or vent pipes can need consent.
- Woodberry Down & Kings Crescent (N4 / N16). New regeneration flats7 with en-suites and modern pressurised systems, where work is usually a like-for-like upgrade.
- Dalston, Hackney Central & Hoxton (E8 / N1). Converted flats where a new bathroom means tying into a shared soil stack and protecting the flat below with sound waste connections and tanking.
- Hackney Wick & Haggerston (E9 / E2). Warehouse conversions and new-builds with concealed services, wet rooms and designer fittings that need careful waterproofing.
- Shoreditch & the Old Street edge (E1 / EC2 / N1). High-spec conversions and en-suites, often with pumped or pressurised showers.
- Homerton & London Fields (E9 / E8). Family terraces adding a second bathroom or en-suite, sometimes in a loft conversion that needs a new waste and soil run.
- Stamford Hill & Upper Clapton (N16 / E5). Larger family homes with more than one bathroom and higher hot-water demand, so the system has to be sized to keep up.
If your area isn’t listed, the principles hold: match the shower to the system, connect the waste and soil properly, and waterproof before you tile.
What it costs
These are plumbing figures — the labour to install and connect fittings — and exclude the suite itself, tiling, plastering and any electrical work. They’re editorial estimates to sense-check a quote — not regulated rates, not market data, and not a published cost survey — and a verified plumber will give you their own price.
| Bathroom plumbing job | Indicative cost (editorial estimate) |
|---|---|
| Install or replace a basin | £100 – £250 |
| Supply and fit a bath (plumbing) | £200 – £450 |
| Fit a mixer or thermostatic shower | £150 – £400 |
| Fit an electric shower (plumbing; electrics separate) | £150 – £350 |
| Install a new WC | £150 – £350 |
| Add or move a soil / waste connection | £300 – £900+ |
| Full bathroom refit — plumbing labour | £1,000 – £2,500+ |
A full refit usually involves more than one trade — a plumber for the supply, waste and fittings, a tiler, and an electrician for an electric shower or extractor — so a quote should be clear about what’s included. On travel: Hackney sits within the London-wide Ultra Low Emission Zone (ULEZ) but outside the central London Congestion Charge zone, so a ULEZ-compliant vehicle adds no daily driving charge to a Hackney job.10 For more on reading a quote, see our plumbing costs guide.
Frequently asked questions
It depends on your system.
A gravity-fed system — loft tank and hot cylinder — is low pressure, so a mixer shower often needs a pump.
A combi boiler is mains pressure and can’t take a pump, so you pick a mains-rated shower.
An unvented cylinder gives strong pressure that suits most mixers, and an electric shower heats its own water, so it works on any system.
A plumber matches the shower to what you have.
Sometimes.
Altering drainage can be notifiable, and electrical work in a bathroom is a job for a qualified electrician.
In a brand-new dwelling there’s also a rule limiting bath hot water to 48°C.
A bathroom installer will tell you what applies to your job.
Approved Document H — drainage and waste disposal
Approved Document P — electrical safety
Approved Document G — sanitation, hot water safety and water efficiency
In a new dwelling, yes — the hot water to a fixed bath must be limited to 48°C, usually with a thermostatic mixing valve.
When you’re refitting a bathroom in an existing home it isn’t a requirement, but it’s sensible to consider, particularly for very young or older household members.
Sound waste and soil connections with proper trap seals, and waterproofing — tanking — under the tiling before the suite goes in.
In a flat-heavy borough this is the detail that prevents a leak becoming your neighbour’s ceiling.
A managed block will usually want the work signed off.
The plumbing, yes.
Tiling and any electrics — an electric shower or an extractor — are separate trades, though some plumbers will project-manage the lot.
It’s worth agreeing up front who does what.
If you rent privately, the bath, basin and hot-water installations are the landlord’s to keep in repair under section 11 of the Landlord and Tenant Act 1985.
Council tenants should report repairs to Hackney Council on 020 8356 3691.
Tenants don’t normally carry out refits.
Why verified plumbers — not a general directory
A bathroom is one of the bigger spends in a home, and most of what you’re paying for is hidden behind tiles — so a botched waste connection or a shower wrongly matched to your system is expensive to put right. Every listing is checked before going live and re-verified annually: we confirm the business is legitimately trading and verify the named contact, we check evidence of public liability insurance, and we confirm the plumber covers Hackney’s E and N postcodes before a profile is approved. For work on your water supply and fittings you can also look a plumber up yourself on WaterSafe, the free, water-industry-backed national register,9 and where a plumber offers gas work — moving a boiler as part of a refit, say — we confirm Gas Safe registration directly with the Gas Safe Register.8 Profiles may be suspended or removed if credentials lapse or credible concerns are raised — see the full verification process →. No customer middleman fee: enquiries go directly to the plumber.

A bathroom is judged on the tiles and the suite, but it stands or falls on the plumbing behind them — the right shower for your system, waste that drains, and connections that don’t leak into the flat below. Get those right first. Everyone listed above is checked before they appear — identity, insurance and trading presence, plus Gas Safe registration where any related work needs it.
