Bathroom repairs: the usual suspects
Failed silicone and grout. The most common “leak” in any bathroom isn’t a pipe — it’s water escaping past perished silicone or cracked grout at the bath or shower edge, soaking into the wall or floor a little with every use. The fix is cheap and unglamorous: rake out, dry, reseal properly. The damage from skipping it isn’t — by the time a ceiling below shows a stain, the joists have been drinking for months. If the stain is already there, the Leak Detection page explains how the source gets confirmed.
Shower problems. Dribbling flow is usually a scaled head or a pressure mismatch (next section); temperature that wanders is typically a worn thermostatic cartridge — a serviceable part, not a new shower; a shower that drips after shut-off is the valve itself. In this borough’s water, all three arrive on a schedule.
Bath and basin wastes. Slow draining is hair and soap until proven otherwise; recurring smells are often a trap or seal issue rather than a blockage. Persistent or multi-fixture problems move to the Blocked Drains page.
Leaks under the bath. Bath waste and overflow connections work loose with use and thermal movement, and they leak only when the bath is full and draining — which is why the floor looks fine until it doesn’t. A removable bath panel is the difference between a five-minute check and exploratory demolition; if your panel is tiled in, say so when you book.
Shut-offs that don’t exist. Plenty of older Richmond bathrooms have no local isolation at all — every small repair becomes a whole-house shut-down. Having isolation valves fitted during any other bathroom job is the standing recommendation from the General Plumbing page, and it never matters more than in a bathroom.
Showers and the pressure question
More bathroom disappointment is manufactured at the point of purchase than at installation, and the cause is almost always pressure. What a shower can deliver is set by what feeds it: a gravity-fed system from a loft tank produces gentle pressure unless pumped; a combi boiler delivers mains-pressure hot water but only at the flow rate the boiler can heat; an unvented cylinder gives mains pressure with stored volume. Each suits different showers — and a high-pressure rain head on a gravity system will drizzle, however much it cost.
So the order of operations for any new shower in Richmond: identify the system (one look in the airing cupboard), match the shower’s requirements to it, and only then choose tiles. Where the system itself is the limit, the honest options are a shower pump (gravity systems), a system upgrade — which becomes a boiler conversation — or choosing a shower designed for low pressure and being pleasantly surprised.
And the borough’s standing tax applies: Thames Water confirms all the water in its region is hard, with blocked shower heads among the everyday consequences it names.1 Descale heads routinely, treat thermostatic cartridges as service items, and if a softener enters the plan, remember Thames Water’s advice to keep a separate unsoftened drinking supply1 — a kitchen detail decided by a bathroom purchase. The wider picture is in the London Hard Water guide.
Refits done right: the plumbing underneath the pretty
A bathroom refit is judged on tiles and lives or dies on first-fix plumbing. The parts that matter are the parts you’ll never see again:
- Falls and waste runs. Every waste needs continuous fall to the stack; wet rooms need it built into the floor. Get this wrong and no amount of finish rescues it.
- Pipework sized and routed for the new layout — not the old one with extensions. Moving a basin two metres on microbore and hope is how flow problems get tiled in.
- Isolation valves on everything, accessibly placed — the refit is the one moment this costs almost nothing.
- Access preserved. Bath panels removable, concealed cisterns with genuine service openings (the Toilet Repairs page explains why), shower valves serviceable from the room.
- Waterproofing as a system — tanking in wet zones, sealed penetrations, silicone as the last line rather than the only one.
- Ventilation in the design. The refit should include the extractor route and capacity, because condensation can mimic leaks and ruin fresh finishes — especially in well-sealed modern refurbishments.
- Electrics agreed up front. If the refit includes an electric shower, extractor fan, lighting, shaver point or underfloor heating, agree who handles the Part P electrical certification before work starts.
- The paperwork. Fittings work must meet the Water Supply (Water Fittings) Regulations 1999, Regulation 4 — appropriate quality, installed in a workmanlike manner2 — and depending on what moves (drainage, ventilation, electrics), ask what must comply with Building Regulations, what needs Building Control approval or competent-person certification, and who is responsible for notification.
A refit is also the cheapest moment to fix everything this site warns about elsewhere: the seized stop tap, the missing isolation, the unlagged run through the cold floor void. The walls are open once. And before handover, ask for the closing checks as a package: pressure testing, waste testing, shower temperature commissioning, silicone cure guidance and any certificates or product manuals.
Richmond’s three bathroom wrinkles
1. The outside of the bathroom is sometimes the council’s business. Bathroom changes often touch the building’s exterior — a new soil pipe, a moved waste, a vent. With 85 conservation areas across the borough,3 external pipework on a visible frontage in places like Richmond Hill, Kew or Barnes can need planning sensitivity rather than just a hammer drill — route wastes internally or to rear elevations where the design allows, and ask the question before the holes are made.
2. Basements: know which question you’re asking. If the bathroom is part of creating, extending or materially altering basement or subterranean accommodation, Richmond’s two basement Article 4 Directions — which cover the whole borough, with planning permission required for basement and subterranean development since 1 April 20184 — mean planning permission may be required. An internal bathroom fitted within an existing lawful basement may not need planning permission at all — but Building Regulations issues such as drainage, ventilation and electrics still need checking. Below-stack bathrooms also need pumped waste or a macerator: ask where the pump can be serviced, how backflow is prevented, and what alarm or access arrangement is included — design decisions that belong on the drawings, not the snag list.
3. Many Richmond bathrooms sit above someone else’s ceiling. In the borough’s mansion blocks, conversions and flats above shops, a bathroom refit is a neighbour-relations exercise: leaks travel down, work makes noise, and shut-offs may be shared — a refit in a Richmond or Twickenham mansion flat can need riser isolation and the managing agent’s involvement before the first fitting moves. Agree access and working hours early, photograph the existing ceiling below if you can, and keep the installer’s documentation; with nearly a quarter of households renting privately,5 the same paperwork answers landlord and tenant questions too.

What bathroom plumbing costs in Richmond upon Thames
Each listed plumber sets their own prices and quotes directly — these figures are an editorial guide to the local range, nothing more.
| Job | Typical editorial estimate |
|---|---|
| Reseal bath/shower (rake out + silicone) | £80–£150 |
| Thermostatic shower cartridge replacement | £100–£200 |
| New shower valve fitted | £200–£450 |
| Bath waste/overflow repair | £90–£180 |
| Basin replaced and plumbed | £150–£300 |
| Full bathroom refit (plumbing first + second fix) | quoted after survey |
Editorial estimates only — not regulated rates, not market data. On refits, insist the quote separates first-fix plumbing, second-fix, and making good — and ask what must comply with the Water Fittings Regulations and Building Regulations, what needs Building Control approval or competent-person certification, and who notifies. Our How to Read a Plumbing Quote guide shows the anatomy; the London Plumbing Costs & Compliance Guide has the wider picture.
Frequently asked questions
Probably, but from where matters: failed silicone or grout letting shower water past, a loose bath waste that only leaks when draining, a weeping joint, or the toilet’s pan connector.
Each leaves a different pattern — silicone failures track with shower use; bath wastes with bath use.
Confirming the source before opening anything is exactly what the Leak Detection page covers.
Pressure mismatch, almost always: the shower was chosen for the showroom, not the system.
A gravity-fed loft-tank system delivers gentle pressure unless pumped; a combi gives mains pressure at limited flow; an unvented cylinder gives both.
Check what feeds yours, then match — pump, system change or a low-pressure-designed shower. See showers and the pressure question .
Usually the thermostatic cartridge — a wear-and-scale service item in this borough’s hard water1 — or pressure being stolen by other outlets on an undersized supply.
A cartridge swap is routine; if temperature swings whenever a tap runs elsewhere, the conversation is about the system, not the shower.
For an ordinary internal bathroom in existing lawful space, normally no.
Two Richmond specifics deserve a check, though: if the work creates, extends or materially alters basement or subterranean accommodation, the borough-wide basement Article 4 Directions mean planning permission may be required,4 and external changes — new soil pipes, vents — on conservation-area frontages deserve a planning check first, with 85 conservation areas in the borough.3
Separately, Building Regulations issues — drainage, ventilation, electrics — can still apply: ask your installer what needs approval or certification and who notifies.

Four things: where the shut-offs are and whether they’re shared, what the lease says about works and hours, who’s below you and what their ceiling looks like today, and whether the design preserves access — bath panel, cistern opening, serviceable valves.
Riser isolation may need the managing agent.
The plumbing answer and the neighbour answer are the same answer: plan it before the first tile moves.
Very much.
A tray contains its own falls and failures; a wet room makes the floor the tray — falls built into the structure, tanking as a system, a flush drain with enough flow, and zero tolerance for shortcuts, because the failure mode is the whole floor.
Wet rooms are excellent when designed and built as one job; they’re unforgiving as an afterthought.
Ground floors and concrete bases take to them more readily than suspended timber.
Failed fixtures, leaking pipework and worn seals are generally the landlord’s repair; report problems in writing early, because bathroom water damage compounds quietly.
Nearly a quarter of the borough rents privately,5 so it’s a standard conversation.
