In Charlton, a full bathroom refit typically costs £6,000 to £20,000 or more (indicative London ranges, MyBuilder and Checkatrade, 2026).

Waterproofing and wet rooms in Charlton
A lasting bathroom starts with getting the waterproofing right, especially in a Charlton terrace with suspended timber floors and solid walls. We tank the wet areas properly before tiling, form falls for a walk-in shower or full wet room, and make sure the drainage and extraction are sized to cope. Skipping the tanking is how leaks and damp start, so we never treat it as optional in SE7 period homes.
Ventilation matters just as much in these older houses, where trapped moisture leads to mould and rot. We fit proper extraction, upgrade the drainage where the original pipework is tired, and can add underfloor heating to keep tiled floors warm and the room drying quickly. The result is a bathroom that looks the part and stays sound in a period Charlton house for years to come.
Housing in Charlton
The valuation list shows roughly 9,540 homes in Charlton, of which 29% are pre-1919, 22% interwar and 49% post-1945, split 49% flats to 51% houses. Terraced houses make up 35% of homes here, and a terrace bathroom in Charlton vents front, back or up, never into a party wall.
Closet wing bathrooms and new soil runs in Charlton
29% of homes in Charlton were built before 1919, and in a Victorian terrace the bathroom was often added later in the closet wing, over the kitchen, with three outside walls and a flat or shallow roof. That can make it the coldest room in the house, and cold walls in a room full of steam grow mould. When the room is stripped, insulating the outside walls on the inside and the ceiling above is the moment to do it, and the extractor is sized for the room, not the smallest fan that fits.
Moving the WC or adding a shower in a Charlton bathroom often means a new connection to the soil stack or the drain outside. Royal Greenwich names a drainage alteration as simple work suited to a building notice, and the notice has to be in two days before that work starts. Plan the pipe route first: the fall from a WC across a closet wing floor is short, and a pan moved away from the stack may need a new branch through the outside wall.
Space-saving en-suites in Charlton terraces
Charlton's Victorian and Edwardian terraces rarely have space to spare upstairs, so a well-planned layout makes all the difference. We often carve an en-suite out of a bedroom corner or rework the awkward footprint of a rear closet wing, choosing compact fittings, walk-in showers and clever storage to get a usable bathroom into a tight SE7 space without it feeling cramped.
Every layout is planned around the existing structure, the run of the soil pipe and the window positions typical of these terraces. We handle the tiling, the underfloor heating, the sanitaryware and the lighting in-house, and any notifiable electrical work in the bathroom is certified by a registered electrician under Part P, or notified to building control, so the finished room is safe, warm and built to make the most of the space.

FAQ
Frequently Asked Questions about Bathroom Renovation Charlton
What is included in your bathroom renovation price in Charlton?
The bathroom renovation price for a Charlton home is itemised as labour, materials, approvals and reinstatement, typically totalling £6,000 to £20,000 or more (indicative). Where a floor or wall needs structural work, GS Renovation appoints and coordinates the engineer and builds to their specification at SE7. Any Royal Borough of Greenwich building control fee has its own line, and the lines follow the order of works: the fall to the waste is set and the walls tanked before tiling.
Can you fit an en-suite into my Charlton terrace without much space?
Usually yes. Charlton's Victorian and Edwardian terraces are tight upstairs, but we can carve en-suites out of a bedroom corner or rework a rear closet wing using compact fittings, walk-in showers and smart storage. We plan the layout around the soil pipe and window positions, tank it properly, sort the ventilation and have the electrics certified by a registered electrician, so a small SE7 space works hard and stays sound.
How long will my Charlton bathroom be out of action?
Budget for 10 to 15 working days between the first tile coming off and the last fitting going on. If it is the only bathroom in your Charlton home, the toilet stays usable for as long as the sequence allows, and you are warned ahead of the days when the water is off. Some families book a shower elsewhere for the tiling stretch, when the room is out of bounds.
Can I move the toilet in my Charlton flat?
Only within reach of the soil stack, which in a flat is usually shared with the homes above and below. The further the pan moves, the harder it is to keep the fall on the waste pipe. The freeholder's written consent is normally required for moving a bathroom, and the stack connection is tested before the floor is closed.
Does a Charlton bathroom above a neighbour need extra waterproofing?
It needs proper tanking, set in the right order. The waste falls are established before the shower tray or wet room former goes down, then the walls and floor are tanked before any tiles. In a flat, a leak comes through someone else's ceiling, so the waterproofing is checked and left to cure before tiling starts.
Will a new shower in my Charlton home have enough pressure?
It comes down to how hot water reaches the tap. Straight off a combi, flow is shared with every other outlet, so an oversized rainfall head can feel weak when the kitchen tap runs. A vented cylinder fed by a loft tank relies on gravity unless a pump is added, whereas an unvented cylinder runs at mains pressure. We look at what your Charlton home has before picking a shower.
Can a Charlton bathroom window be changed to obscure glass at a Rectory Field address?
Check the guidance note first. The Rectory Field Conservation Area Article 4 direction requires planning permission, at the addresses it names, for installing or altering windows or doors. Swapping clear glass for obscure glass in the existing frame may or may not count as altering the window, so ask the planning team with the house number before ordering. A blind or window film inside the room avoids the question.
Do extra en suites in a Charlton house need planning permission?
Not while it stays a family home. The trigger is use: since 27 September 2018 a Royal Greenwich Article 4 direction has withdrawn, across the whole borough, the right to turn a house into an HMO without permission. En suites fitted to every bedroom so each room can be let on its own point towards that use. Settle the planning position before the soil runs are designed.
Can a bathroom be moved in a Charlton flat built after 2000?
Only within the building's design. 14% of homes in Charlton were built in 2000 or later, and in a newer block the bathroom waste typically drops into a service riser shared with the flats above and below. The shower tray, WC and basin can be changed, but moving them away from the riser rarely works in a concrete floor. Ask the managing agent for the services drawings first.
