Bathroom refits and renovations in Hounslow

Bathroom renovation in Hounslow, 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.

Hounslow overview

Bathroom renovation in Hounslow

West London borough close to Kingston and Richmond, with a mix of suburban housing stock needing general repairs and roofing. Hounslow falls well within the West London ground Lian Construction covers on a regular basis. For bathroom renovation work in Hounslow, that local knowledge means fewer surprises once work is on site and a team that already understands the borough's typical property stock.

Hounslow's housing stock is largely shaped by its position between the inner suburbs and the Thames-side towns of Kingston and Richmond, meaning much of the borough consists of suburban semi-detached and terraced houses built through the interwar and post-war expansion of west London. Rows of 1930s semis with bay windows and pitched tiled roofs are common, alongside pockets of Victorian and Edwardian terraces closer to older village centres, and later 20th-century estates further out. This mix means roof types vary across the borough: traditional pitched slate or tile roofs on older properties, and a mix of tile and flat-roof extensions on inter-war and post-war stock. General wear is the main driver of work - guttering, pointing, roof coverings and rendering that have simply aged, rather than anything structurally unusual. Many houses have had extensions or loft conversions added over the decades, which means roofline junctions, flashings and old extension roofs are often where problems show up first. For a homeowner, that typically means routine maintenance and repair work rather than large-scale rebuilds, though older properties can throw up surprises once you get up on the roof or open a wall.

Hounslow sits at the edge of west London's commuter belt, within easy reach of Kingston and Richmond, and demand for repair and roofing work tends to track the age of its suburban housing rather than any single trend. A lot of the borough's semis and terraces are now well past the point where original roofs, guttering and brickwork need attention, so ongoing maintenance and reactive repair work - fixing leaks, replacing worn tiles, sorting out damp - make up a steady share of the work available. Because Hounslow sits between higher-profile areas like Richmond and Kingston, some homeowners default to calling contractors based further out or in those neighbouring boroughs, which can mean longer wait times or higher call-out costs for straightforward repair jobs. That leaves room for a contractor who responds promptly to general repairs and roofing work without treating it as an afterthought to bigger projects. For landlords with rental stock in the borough, keeping on top of routine repairs also matters for avoiding bigger, costlier issues later, particularly with roofing, where a small leak left unaddressed can lead to more extensive internal damage.

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 Hounslow?

  • You're planning a wider refurbishment and want the bathroom sequenced alongside other rooms rather than treated as a separate later project.
  • 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.

Questions

Bathroom renovation questions in Hounslow

How quickly can Lian start bathroom renovation work in Hounslow?

Hounslow is part of our regular West 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 Hounslow?

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

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.

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.
