Bathroom refits and renovations in Southwark

Bathroom Renovation in Southwark, London

Lian Construction carries out full bathroom renovations across London, across all of London, from inner boroughs out to South West London and the wider capital. We handle the whole refit as one project: strip-out, replumbing, tanking wet areas, tiling, electrics and sanitaryware, rather than leaving you to coordinate a plumber, tiler and electrician separately. Work ranges from a straightforward bathroom refresh in a Victorian terrace to a small ensuite squeezed into a box room, or a full wetroom conversion. We survey the room, agree a realistic layout for the space available, and sequence the trades properly so the finished bathroom is watertight, compliant and built to last, not just good-looking on handover day.

Southwark overview

Bathroom Renovation in Southwark

Active property market around Peckham and Bermondsey, with 800+ new council homes underway and strong buy-to-let refurbishment demand. Southwark falls well within the South London ground Lian Construction covers on a regular basis. For bathroom renovation work in Southwark, that local knowledge means fewer surprises once work is on site and a team that already understands the borough's typical property stock.

Housing stock in Southwark spans several distinct eras. Peckham and the surrounding streets have a good deal of Victorian and Edwardian terraced housing, typical of inner London's rapid nineteenth-century expansion, alongside interwar and postwar low-rise estates. Bermondsey, given its history as a working wharf and warehouse district, has a mix of converted industrial buildings sitting alongside traditional terraces and mid-rise blocks, a pattern common in London's former riverside industrial areas. With 800+ new council homes underway across the borough, there's also a growing share of newer build stock, which brings different maintenance and refurbishment needs than the Victorian terraces nearby, think modern insulation, service runs and warranty considerations rather than solid-wall damp and old timber. For homeowners and landlords, this mix means a wide range of jobs: period property repair and upgrade work on older terraces, conversion and refurbishment work on ex-industrial buildings, and fit-out or snagging work on newer stock. It's a borough where a contractor needs to be comfortable moving between very different building types and ages, sometimes on the same street.

Southwark's property market, particularly around Peckham and Bermondsey, has stayed active for some time, and that shows in the volume of refurbishment and improvement work landlords and owner-occupiers are commissioning. Buy-to-let refurbishment demand is strong: with rental interest firm in these areas, landlords are investing in kitchen and bathroom upgrades, rewiring and general modernisation to keep properties competitive and up to current letting standards. The 800+ new council homes underway across the borough also point to a wider building pipeline locally, which tends to pull more trades and subcontractor activity into the area generally, and can make it harder to get a reliable contractor booked in at short notice. For homeowners, this means it's worth planning refurbishment work with some lead time rather than expecting immediate availability, particularly for larger or structural jobs. For landlords managing multiple units, coordinating between-tenancy refurbishment efficiently matters more here than in quieter markets, since void periods are costly and good contractors are being pulled in several directions by both private and public sector work at once.

Tanking, waterproofing and wet zones

Any area that gets wet regularly needs proper waterproofing behind the tile, not just grout and silicone holding the water back at the surface. We follow the zone approach set out in BS 5385 for tanking: the shower enclosure itself, the floor area immediately around a bath, and a reasonable margin beyond a basin splash zone all get a waterproof membrane, either a liquid tanking system rolled onto boards in several coats or a bonded sheet membrane taped at joints and corners, before any tile adhesive goes on. Shower trays and formed wetroom floors are treated differently. A shower tray sits on a supporting frame or upstand, with the membrane dressed up the surrounding walls and over the tray edge so water can't track behind it, while a true wetroom floor is built to fall towards a linear or point drain, using a tapered former or a screed laid to falls, with the membrane taken up the walls and across the whole floor area, not just around the drain itself. Getting the falls wrong on a wetroom floor is one of the more expensive mistakes to correct after tiling, since standing water pooling away from the drain usually means lifting the floor and starting the build-up again from scratch. We pressure-test or flood-test waterproofing on wetroom floors and shower enclosures before tiling wherever practical, leaving standing water in place for a set period and checking below for any sign of a leak, rather than assuming a membrane has taken without checking it. Finding a pinhole or a poorly sealed corner joint after the tiles are down is a far bigger and more disruptive job than finding it before a single tile has been laid.

Electrics, ventilation and lighting in bathrooms

Bathrooms are a special location under BS 7671, the UK wiring regulations, and the room is divided into zones based on distance from water: zone 0 is inside the bath or shower itself, zone 1 covers the area directly above it up to 2.25 metres, zone 2 extends a further 0.6 metres beyond that, and everywhere outside those areas is treated as zone 3 or unzoned. Fittings need an ingress protection rating suited to the zone they sit in: a shower light typically needs at least IP65 if it's positioned in zone 0 or 1, and standard 13-amp socket outlets aren't permitted within the zoned area at all, other than a shaver socket to BS EN 61558-2-5, which is the reason bathrooms only ever have a dedicated shaver point rather than a normal switched socket near the basin. Mechanical extraction is a Building Regulations Part F requirement, not just good practice, and a bathroom without an openable window to outside air needs a fan ducted out, sized appropriately to the room volume, and in windowless bathrooms it typically needs a timer overrun so it keeps running for several minutes after the light switches off rather than stopping the moment you leave the room. Switch position is worth planning early in a small bathroom too. A standard light switch mounted on the wall inside the room needs to sit outside the zoned area or be a pull-cord type if it's within reach of the bath or shower, which is why older bathrooms often have a ceiling-mounted pull-cord even where a modern wall switch would otherwise be preferred. In a tight ensuite where every wall is close to the bath or shower, this sometimes limits switch position more than people expect, and it's worth confirming with the electrician at first-fix stage rather than after the wall's already been tiled. We coordinate all of this electrical work with a qualified electrician who tests and certifies it, since bathroom electrical work is notifiable under Part P of the Building Regulations, and we build the certification into the handover pack alongside the rest of the job's documentation and photographs.

Signs to look for

Do you need bathroom renovation in Southwark?

  • Ventilation is poor, with condensation and mould building up on the ceiling or around the window despite an existing extractor fan.
  • The bathroom hasn't been updated in fifteen years or more and the sanitaryware, tiling and waterproofing all show their age together.
  • Grout or silicone around the bath or shower has failed repeatedly despite resealing, suggesting the waterproofing behind the tiles has broken down.
  • You're converting a boxroom, understairs space or end of a landing into an ensuite and need the layout properly worked out first.

Questions

Bathroom Renovation questions in Southwark

How quickly can Lian start bathroom renovation work in Southwark?

Southwark is part of our regular South London coverage, so once we've surveyed the property we can usually confirm a start date quickly. Send the address and scope and we'll arrange the next step.

Do you cover all of Southwark?

Yes. Southwark falls within the area Lian Construction serves across Greater London.

What's driving refurbishment demand in Southwark at the moment?

A large part of it is the combination of an active property market around Peckham and Bermondsey and ongoing council house-building, with over 800 new homes underway locally. That tends to push up general demand for trades and refurbishment work across the borough, both from landlords upgrading existing stock to stay competitive and from owner-occupiers improving properties they've bought into an active market. It's not something you can pin down to one single cause, but it does mean the trades market locally is busier than in some other parts of London.

Do you offer a guarantee on waterproofing and tanking work?

We agree workmanship cover as part of the written quote before work starts, since the appropriate period depends on the scope of tanking and tiling involved. We test wetroom floors and shower waterproofing before tiling wherever practical, rather than assuming a membrane has taken without checking, because finding a fault after the tiles are down is a far more disruptive fix than catching it beforehand. If an issue does show up after handover, get in touch and we'll come back to assess it properly.

How much does a bathroom renovation cost in London?

It varies considerably depending on whether the layout is changing, the sanitaryware specification, and how much tiling and waterproofing the room needs. A like-for-like refit on a small bathroom with standard fittings costs meaningfully less than a full reconfiguration with a wetroom floor, underfloor heating and higher-specification sanitaryware. We give a fixed price after surveying the room and agreeing the specification with you, broken down by plumbing, electrics, waterproofing, tiling and fittings, rather than a single figure that hides where the money is actually going. Getting more than one quote is sensible, but check each one is pricing the same scope in the same detail.

Can you fit an ensuite into a small room like a boxroom?

Often yes, though it depends on the room's dimensions and where the nearest waste and water supply runs are. A boxroom or the end of a landing can frequently take a corner shower, a wall-hung WC and a slimline basin, but door swing, ceiling height and where pipework can realistically be routed all need checking before committing to a layout. We'll survey the space and tell you plainly if a workable ensuite is achievable within it, rather than promising a layout that turns out not to fit once work starts, and we'll suggest sensible alternatives where the original idea doesn't quite work.
