Wet rooms and en-suites in Greenwich
Wet rooms and walk-in showers are a favourite in Greenwich homes, but they only work if the waterproofing is done right. We fully tank the floor and walls before a single tile goes on, set the falls so water runs to the drain, and make sure the ventilation clears moisture, which matters most in the solid-walled period houses. In SE7 and SE18 that groundwork is what keeps a wet room reliable.
En-suites are a common ask in Greenwich's larger Georgian and Victorian houses, where a bedroom can spare the space. We plan the drainage runs carefully, since routing new soil pipes through a period property takes thought, and add underfloor heating and good extraction. The finish, from tiling to fittings, is chosen to suit the age of the house rather than fight it.
Housing in Greenwich
The stock in Greenwich runs to roughly 125,080 dwellings, 55% of them flats and 45% houses, built 22% before 1919, 17% between 1919 and 1939 and 60% after 1945. Where most homes are flats, a bathroom in a flat in Greenwich sits over a neighbour's ceiling, so tanking comes first.
En-suites for sharers and cellar shower rooms in Greenwich
Adding en-suites is one way a Greenwich house is prepared for letting by the room, and that is where a bathroom project meets planning. Since 27 September 2018 Royal Greenwich has had a borough-wide Article 4 direction requiring planning permission to convert a house into an HMO. Three or more unrelated tenants sharing a kitchen or bathroom puts a house in HMO use, even when every room has its own shower, so an owner fitting en-suites to let rooms should have that permission before the soil pipes go in. A family adding an en-suite for its own use is not affected.
A shower room in a cellar is the other bathroom that brings Royal Greenwich's rules in. Where the scheme needs planning permission, turning a cellar into habitable accommodation next to other homes needs a Basement Impact Assessment. In flood zone 2 a basement is not normally permitted unless it has no habitable rooms, and in flood zone 3 it is not permitted at all. Whether a cellar shower room counts as habitable, and whether a pump is needed to lift the waste to the drain, are two questions to settle before a Greenwich cellar is tanked.
Space-saving bathrooms in Greenwich period homes
Not every Greenwich bathroom is generous. Many terraces in SE10 and SE18 have a narrow bathroom over the rear closet wing, so a clever layout matters. We use wall-hung units, compact walk-in showers and considered storage to make a small room feel larger, while keeping the plumbing sensible. The aim is a bathroom that looks calm and uncluttered without sacrificing what you actually need.
Every bathroom we fit includes proper tanking, tiling, drainage and ventilation, with any notifiable electrical work certified by a registered electrician under Part P or notified to building control, as bathroom electrics must be. Underfloor heating is a popular upgrade under stone or porcelain tiles. Across Greenwich one team runs the whole job, from stripping out the old suite to the final seal, so there is no gap between trades and no water finding its way where it should not.

FAQ
Frequently Asked Questions about Bathroom Renovation Greenwich
Are there hidden costs with bathroom renovation in Greenwich?
The risk of extra cost on bathroom renovation in Greenwich sits in what is concealed. GS Renovation lists what the SE10 survey could not inspect, so you know where the figure within £6,000 to £20,000 or more (indicative) might move. The route for an extract duct to outside decides how much ceiling comes down, which is why that point is opened up early. Any Royal Borough of Greenwich building control fee and any Part P electrical certificate are priced from the start.
Can you fit a wet room in my period Greenwich home?
Yes. Wet rooms work well in Greenwich period homes provided the waterproofing is thorough. We fully tank the floor and walls, set the drainage falls correctly and fit proper ventilation to handle moisture in solid-walled rooms. No planning permission is needed for an internal bathroom, though new circuits and circuit changes near the bath or shower are notifiable under Part P. We manage the whole installation so it stays watertight for years. A listed building is the exception: work that affects its character, inside or out, including an extension or taking out a wall or chimney breast, needs listed building consent from the Royal Borough of Greenwich, and doing it without consent is a criminal offence.
How long will I be without a bathroom in my Greenwich home?
Usually 10 to 15 working days from strip-out to handover. The order is fixed: first fix pipework and wiring, then waste falls set before the tray or former goes in, tanking before tiling, and sanitaryware last. The toilet can often be reconnected overnight during the middle stage, so a house with only one bathroom is not without a toilet for the whole period.
Can the toilet move to the opposite wall in my Greenwich bathroom?
Only if the soil pipe can reach the stack with a steady fall. That depends on distance and on joist direction: running between joists is easy, crossing them means notching that weakens the floor. On a concrete floor in a post-war block the run must be chased or raised. Where the stack is too far away, a small macerator unit is sometimes the fallback, though a gravity connection is always better.
Will a rainfall shower work with the combi boiler in my Greenwich house?
It depends on the combi's flow rate and the mains pressure in the street, because every outlet shares that one supply. An unvented cylinder can feed several outlets at mains pressure, while an older gravity system with a tank in the loft often needs a pump. The hot water arrangement is decided before first fix, as the pipe sizes and the valve depend on it.
Can the joists in an older Greenwich house carry a heavy freestanding bath?
They need checking first. A cast-iron or stone bath filled with water and a person weighs far more than the joists ever expected to carry at one point. Joists previously notched for pipes are the weak spot. The engineer may specify doubling the joists under the bath or spreading the load across more of them, done while the floor is up at first fix.
Can an en-suite be added to a Greenwich flat without touching the building's drains?
Rarely, since it needs a connection to the shared soil stack. In Greenwich 55% of homes are flats, and Royal Greenwich building control lists drainage alteration among the simple jobs a building notice suits. The notice covers the building regulations; the lease covers the rest. The stack serves the whole building, so the lease usually requires the freeholder's consent for a new connection, which is made at a point building control can see before it is boxed in.
Who tells Royal Greenwich when a new Greenwich bathroom is finished?
Whoever you agree. The completion notice has to reach Royal Greenwich within five days of the work being completed, and the client, the agent or the builder can send it. On a bathroom with new drainage or electrics, agree at the start what counts as the finish date and who sends the notice, and file the certificate that follows with the electrician's paperwork.
Where does a second bathroom fit in an interwar Greenwich house?
One candidate, where the house has one, is the small box room over the front hall. In Greenwich 17% of homes were built between 1919 and 1939, and that room is a familiar feature of the period. The layout question is the soil pipe: it has to reach the existing stack with a steady fall, or run to a new stack on an outside wall. The structural engineer we appoint checks the floor for a bath, and the drainage goes on the building notice.
