Wet rooms and waterproofing in Camberwell
Waterproofing is where a Camberwell bathroom succeeds or fails. In period townhouses with timber floors and old plaster, we tank the walls and floor properly before tiling, forming a continuous waterproof layer that protects the structure below. For wet rooms and walk-in showers, we set the falls correctly so water drains cleanly, and we upgrade the drainage and ventilation to prevent damp taking hold in SE5's solid-walled homes.
Underfloor heating suits Camberwell bathrooms well, warming tiled floors that would otherwise feel cold in an old townhouse and freeing up wall space taken by radiators. We run the plumbing and electrics to current standards, with notifiable electrical work certified by a registered electrician under Part P, or notified to building control. From large family bathrooms to compact shower rooms, we tile, seal and finish to a standard that stands up to daily use for years to come.
Housing in Camberwell
For Camberwell the Council Tax list gives about 13,560 homes; by type 85% flats and 15% houses, by age 56% post-war, 7% interwar and 34% older than 1919. Since most homes here are flats, a bathroom in a flat in Camberwell sits over a neighbour's ceiling, so tanking comes first.
A second bathroom or en-suite in a Camberwell flat
Adding a shower room or en-suite to a Camberwell flat is a new installation, and Southwark's final fees and charges schedule carries a separate building control charge for installing a new WC, shower or utility, shown before VAT. A like for like refit in the same position does not normally need an application. A new room does, because it adds a drainage connection, a fall to the stack and extraction to outside, and those are what building control inspects before the floor is closed up.
85% of homes in Camberwell are flats, so a new shower room is likely to sit over another household's rooms. The waste has to reach the shared stack without deep notches in joists that also carry the neighbour's ceiling, and the lease may need the freeholder's consent for a new wet room. Place the new bathroom above the existing wet rooms of the flat below where the plan allows, which keeps pipe runs short and puts any leak over a tiled room instead of a bedroom.
En-suites and space-saving layouts in Camberwell
Adding an en-suite to a Camberwell bedroom, or fitting a bathroom into an awkward SE5 corner, calls for careful planning. We work out where soil pipes and waste can run within a period structure, then design a layout that fits real fixtures without feeling cramped. Wall-hung basins, compact showers and clever storage help us make the most of the tight footprints so common in these older townhouses.
Period Camberwell homes rarely offer generous bathroom space, so every centimetre counts. We reconfigure existing rooms, borrow space from landings or cupboards where it makes sense, and choose sanitaryware scaled to the room. Ventilation is planned in from the start to keep the space healthy, and the tiling, heating and lighting are finished to suit the character of the house. Internal bathroom work like this needs no planning permission.

FAQ
Frequently Asked Questions about Bathroom Renovation Camberwell
Which parts of a bathroom renovation project in Camberwell cost the most?
Which part of a bathroom renovation project in Camberwell costs most depends on the house, which is why the survey comes first. In older stock reinstatement often outweighs the structural element; a newer SE5 property is the other way round. GS Renovation prices the two separately within £6,000 to £20,000 or more (indicative), so phasing is possible, provided the order holds: any underfloor heating is laid and tested before the floor is tiled.
Why does a Camberwell basement or lower ground floor stay damp?
Groundwater is a likely reason here, not simply condensation. Southwark's Strategic Flood Risk Assessment states that much of the borough is underlain by London Clay, an aquiclude. It adds that the London Clay is absent in parts of the Camberwell and Bermondsey areas, although British Geological Survey mapping still returns it at Camberwell Green and Denmark Hill, that hydraulic continuity between bedrock and superficial aquifers may exist, and that groundwater in the Chalk and Thanet Sand is high. British Geological Survey mapping records sand and gravel at the Coldharbour Lane and Denmark Hill junction and at Lettsom Street.
Can a bathroom window be changed to obscured double glazing in Camberwell?
Yes, provided the replacement is like for like in material, size and design. Southwark's Householder Development SPD states that like for like replacement in a conservation area does not need planning permission and that the glazing type can change from single to double. It also states that UPVC will not be permitted in a conservation area or listed building, even to the rear, and the Camberwell Grove appraisal rules out casement and tilt and turn designs.
Can a shower room go in the loft with a dormer in Camberwell?
Rarely in a conservation area, and a box dormer will be refused. Southwark's Householder SPD states that planning permission is required for roof extensions within a conservation area, and that dormers should sit within the existing roof without dominating its form. It adds that box dormers or overly large dormers will not be permitted in conservation areas or for listed buildings. The Camberwell Grove appraisal states that changes to the basic roof form are generally unacceptable.
Can a soil pipe be run up the front of a Camberwell New Road house?
No, the front elevation is the worst place for it. The Camberwell New Road Conservation Area was designated in September 1968. It takes in late Georgian terraces and groups of mainly terraced houses of mid to later 19th century date, along with a triangular area bounded by the railway line and Flodden Road. New pipework on a principal elevation there is resisted, so route it internally or take the stack to the rear.
Is a licence needed for scaffolding to reach a first floor bathroom window?
Yes, wherever any part of it stands on the highway. Southwark grants scaffolding licences under section 169 of the Highways Act 1980 and hoarding licences under section 172, and asks for at least 15 working days notice ahead of the start date. Charges run in bands by length, up to 10 metres, 10 to 50 metres and over 50 metres, with a deposit per metre applied to new applications. That notice period sets the start date.
Will a top floor shower in a tall Camberwell townhouse have enough pressure?
Not always on the original tank. The housing in Camberwell is described on the site as including Georgian and Victorian townhouses, and where the cold water tank sits in the roof, a shower on the floor just below has little head of water. The usual answers are a pump, an unvented cylinder fed from the mains, or a system boiler with the mains pressure tested first at the lowest tap.
How is a bathroom in a post-war Camberwell block plumbed?
Usually into a shared stack in a duct. 56% of homes in Camberwell were built after 1945, and in a block of that period the bathrooms on each floor may be stacked over one another around a common soil pipe. A concrete floor slab leaves no void to run a new waste across the room, so moving the WC away from the duct needs a raised floor or a pumped unit. The building drawings show the duct position.
Whose insurance pays if a new Camberwell bathroom leaks into the flat below?
Check before the work starts. 85% of homes in Camberwell are flats, and in a leasehold block the buildings insurance is often arranged by the freeholder, with its own terms about alterations. Tell the freeholder and the insurer about a new bathroom, keep the pressure test record for the new pipework and fit an isolation valve that the occupants can reach, so a leak is stopped in minutes rather than hours.
