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.
Newham overview
Bathroom Renovation in Newham
Stratford regeneration continues to drive refurbishment and repair demand across converted and new-build stock alike. Newham falls well within the East London ground Lian Construction covers on a regular basis. For bathroom renovation work in Newham, that local knowledge means fewer surprises once work is on site and a team that already understands the borough's typical property stock.
Newham's housing stock is a mix of eras rather than one dominant type. Older neighbourhoods away from the Stratford core still have Victorian and Edwardian terraces, along with inter-war and post-war housing, much of it converted into flats over the decades. Around Stratford itself, the picture is different: large-scale new-build apartment blocks have gone up since the Olympic regeneration began, alongside conversions of older industrial and commercial buildings into residential use. This mix means work in the borough spans everything from traditional repair and repointing on period terraces to snagging and remedial work on newer builds, plus the specific issues that come with converting non-residential buildings into homes. For a contractor, this variety matters: a Victorian terrace and a five-year-old conversion flat fail in different ways and need different approaches. Owners and landlords in Newham are as likely to be dealing with settlement cracks in a new block as damp in an old one, so it helps to work with a contractor who isn't only set up for one type of property.
The continued regeneration around Stratford has kept refurbishment and repair demand high across Newham, and that demand isn't limited to new-build. Converted properties, some created during earlier waves of development, are now old enough to need attention themselves, while newer stock often surfaces defects and snagging issues in the first few years. For homeowners and landlords, this means the borough has a steady flow of work but also a busy trade, and finding a contractor with availability can take longer than in quieter areas. Landlords managing flats in converted or new-build blocks tend to deal with a narrower set of recurring issues, plasterwork, minor leaks, finishing snags, while owner-occupiers in older terraces further from the centre are more likely to need broader repair or refurbishment work. Given how much building activity the regeneration has brought to the area, it's worth getting quotes early and being clear about timescales, since demand can affect how quickly work gets scheduled. Property type also affects who you need: not every firm working in Newham is equally comfortable across period terraces and modern conversions.

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 Newham?
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 Newham
How quickly can Lian start bathroom renovation work in Newham?
Newham is part of our regular 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 Newham?
Yes. Newham falls within the area Lian Construction serves across Greater London.
I'm a landlord with flats in both an older converted building and a newer block. Do they need different approaches?
Generally yes. Converted period buildings tend to need more attention to the original structure and older services, while newer blocks are more likely to need finishing or snagging fixes early on and then settle into standard maintenance. It helps to work with a contractor comfortable across both, rather than one geared only towards one type of property, especially if you're managing several units across the borough.
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.
