Bathroom refits and renovations in Southwark

Bathroom renovation in Southwark, London

Lian Construction carries out full bathroom renovations across London, from Kingston upon Thames out across 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.

How long does a full bathroom renovation take?

A straightforward like-for-like refit, replacing the suite and tiling without moving pipework, usually takes one to two weeks. Where the layout is changing, a WC or shower moving position, or a bath being replaced with a walk-in shower, three to four weeks is more realistic once you account for tanking cure times and any structural work to floor joists. We'll give a firm programme once we've surveyed the room and confirmed the layout, rather than a generic figure that doesn't reflect what your specific bathroom needs.

Can you fit a wetroom instead of a standard shower enclosure?

Yes. A wetroom needs the floor built to fall towards a drain, using a tapered former or screed, with the waterproof membrane taken across the whole floor and up the walls rather than just around a tray. It's a bigger job than fitting a shower tray, since floor height and drainage need checking early, particularly on an upper floor or in a flat where floor build-up is limited, but it gives a level, step-free finish that works well for smaller rooms and for anyone wanting easier long-term accessibility.

Can you move the toilet or shower to a different part of the room?

Yes, though it depends on how the new position relates to the existing soil stack and waste run. A WC generally needs a consistent fall back to the stack, and where the new position can't achieve that with standard pipework, we'd look at options such as building up the floor slightly or fitting a macerator unit. We'll check this at survey stage and tell you honestly if a layout change is straightforward or adds meaningful cost and floor build-up before you commit to a specific design.

Do you fit underfloor heating in bathrooms?

Yes, we can supply and fit electric underfloor heating mats or cables beneath the tiled floor, coordinated with a qualified electrician for the final connection, testing and certification. It goes in after levelling and before tiling, using a flexible adhesive suited to the slight movement caused by heating cycles. It's worth deciding on underfloor heating early in the design, since it adds a stage to the floor build-up and affects the finished floor height, which can matter in a small bathroom where door clearance is already tight.
