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.
Bexley overview
Bathroom Renovation in Bexley
South East outer London borough with suburban family housing well suited to roof replacement and property repair work. Bexley falls well within the South East London ground Lian Construction covers on a regular basis. For bathroom renovation work in Bexley, that local knowledge means fewer surprises once work is on site and a team that already understands the borough's typical property stock.
Bexley is a South East outer London borough made up largely of suburban family housing, the kind built up through the interwar and post-war decades as London's suburbs expanded outward. Semi-detached and detached houses with pitched, tiled roofs are the dominant type, often dating from the 1920s to 1950s, alongside pockets of later 1960s and 1970s estate housing. This mirrors the pattern found across much of outer South East London, where dense Victorian and Edwardian terraced stock gives way to more spaced-out family homes with gardens, driveways and traditional gable or hip roof designs. Roofs of this age and type are now well past their original lifespan in many cases, particularly where original tile coverings, flashing and guttering have not been replaced or properly maintained over the decades. This makes roof replacement and repair a recurring, practical need for homeowners across the borough rather than a rare event. The suburban layout, with reasonable space and access around most properties, also tends to make scaffolding and roof work more straightforward to carry out than on denser, terraced inner-London streets.
The suburban family housing that dominates Bexley means demand for roof replacement and general property repair tends to be steady and ongoing rather than driven by large development projects. Owner-occupiers make up a significant share of this type of housing, and owner-occupiers are usually the ones commissioning repair work directly, rather than managing agents overseeing large contracts. For a homeowner in Bexley, this generally means less competition from big multi-contractor developments for local tradespeople's time, though it can also mean a smaller pool of established contractors experienced with the specific mix of interwar and post-war roof types found here, compared with more built-up parts of London. Ageing roof coverings, worn flashing and guttering issues caused by general wear and London's weather are the most common triggers for enquiries in this kind of borough, rather than large-scale renovation or extension work. Homeowners weighing up roof replacement or repair in Bexley are usually best served by getting a clear, itemised quote that separates like-for-like repair from full replacement, since the age of much of the housing stock means both options are genuinely on the table depending on the condition of the existing structure and covering.

What drives the cost of a bathroom renovation
Bathroom cost varies more than most rooms in a house because so much of it depends on what's happening behind the tiles rather than the visible finish alone. Moving the WC or shower to a new position is usually the single biggest cost driver, since a soil pipe needs a consistent fall, typically around 18mm per metre for a 100mm pipe, back to the stack or drain, and where the new position doesn't allow that fall naturally, the floor sometimes needs building up, joists notched and strengthened within Building Regulations limits, or a macerator unit considered instead of gravity drainage. Retiling from scratch costs more once you factor in stripping old tiles, checking and levelling the substrate, and fitting a waterproofing membrane before a single tile goes up, rather than tiling over what's already there. Sanitaryware and fittings vary enormously in price for a similar footprint: a basic close-coupled WC and a wall-hung one with a concealed cistern occupy the same floor space but cost very differently to supply and fit, and taps, shower valves and brassware range from budget chrome mixers to thermostatic bar valves and rainfall heads at several times the price. Underfloor heating, a walk-in shower rather than a bath, and a wetroom floor formed to falls rather than a standard shower tray, all add both cost and time to the programme. We break quotes down by these categories, structural and plumbing changes, waterproofing, tiling, sanitaryware and electrics, rather than a single lump figure, so you can see exactly where a change in specification moves the overall price. As a broad guide, a like-for-like refit with standard sanitaryware and mid-range tiling sits at the more affordable end of the range, a full reconfiguration with a wetroom floor and higher-specification fittings sits considerably higher, and a small ensuite squeezed into an awkward space can sometimes cost more per square metre than a larger, more straightforward bathroom, simply because the fixed costs of plumbing, tanking and electrics don't shrink in proportion to the room size.
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.

Signs to look for
Do you need bathroom renovation in Bexley?
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.
A leak or damp issue has damaged the bathroom floor or walls and the room needs stripping back and reinstating properly.

Questions
Bathroom Renovation questions in Bexley
How quickly can Lian start bathroom renovation work in Bexley?
Bexley is part of our regular South East 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 Bexley?
Yes. Bexley falls within the area Lian Construction serves across Greater London.
My house is from the 1930s, does the roof need full replacement or can it just be repaired?
It depends on the condition of the roof structure, not just its age. Many 1930s roofs in Bexley still have sound timber underneath, and if only the covering, flashing or guttering has failed, a repair or partial re-cover can be enough. But if there's been ongoing damp ingress, sagging, or the felt underneath has broken down, replacement usually works out better value than repeated patching. A proper inspection is the only way to know for sure, so it's worth getting one before deciding either way.
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.
What ventilation does a bathroom legally need?
Building Regulations Part F requires mechanical extraction in any bathroom without an openable window to outside air, ducted out rather than just recirculating into the loft or a void. Even where there's a window, many bathrooms still benefit from a fan, particularly windowless ensuites and shower rooms where condensation builds up quickly. We size the fan to the room volume and, for windowless bathrooms, typically fit one with a timer overrun so it keeps running for a few minutes after the light switches off, which clears humidity properly rather than stopping the moment you leave the room.
Can bathroom renovation work be done while I'm still living in the property?
For a single bathroom, yes, provided there's another bathroom or WC available elsewhere in the property during the works, since the room being renovated will be out of use for most of the job, typically from strip-out through to the tanking curing. Where it's the only bathroom in the property, we'll talk through options for minimising how long you're without facilities, though a full renovation with tanking and tiling realistically needs the room out of action for the bulk of the programme rather than usable in stages.
