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.
Hillingdon overview
Bathroom Renovation in Hillingdon
West London borough near Heathrow, with a broad mix of housing types needing refurbishment and general building work. Hillingdon falls well within the West London ground Lian Construction covers on a regular basis. For bathroom renovation work in Hillingdon, that local knowledge means fewer surprises once work is on site and a team that already understands the borough's typical property stock.
Hillingdon's housing stock reflects its position as an outer west London borough that grew substantially through the interwar and postwar periods, alongside older cores around its traditional town centres. Expect a broad spread: 1930s semi-detached and terraced housing built as London's suburbs expanded along the western rail and tube corridors, postwar estates and infill from the 1950s-60s, and pockets of older Victorian and Edwardian terraces closer to the historic centres. More recent decades have added modern estate housing and some higher-density new-build, partly linked to the borough's role as a major employment and transport hub near Heathrow. This mix means refurbishment work varies widely in character: solid-wall older properties often need different approaches to insulation, damp and roofing than cavity-wall postwar housing, and newer stock brings its own snagging and extension challenges. A contractor working across Hillingdon needs to be comfortable moving between these eras rather than specialising in one type, since a single street can contain anything from a 1930s semi to a 1990s infill house.
Hillingdon's location next to Heathrow shapes demand in practical ways. A large share of housing serves a working population tied to the airport and surrounding logistics and business parks, which tends to mean higher churn in the private rental sector and steady demand for quick, reliable turnaround work between tenancies: redecoration, repairs, kitchen and bathroom refreshes, and general maintenance that keeps a property lettable. Landlords in this position usually want a contractor who can scope a job fast and work to a clear timeline, since void periods cost money. At the same time, the borough's broad mix of housing types means demand for larger projects - extensions, loft conversions, roofing - comes from owner-occupiers across very different property styles, not a single dominant demographic. Because Hillingdon sits toward the edge of a typical London contractor's usual coverage area, homeowners here can sometimes find it harder to get firms to travel out for smaller jobs, or face longer lead times than in more central boroughs. That gap tends to favour contractors willing to commit to the area consistently rather than treat it as an occasional job.

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 Hillingdon?
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 Hillingdon
How quickly can Lian start bathroom renovation work in Hillingdon?
Hillingdon 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 Hillingdon?
Yes. Hillingdon falls within the area Lian Construction serves across Greater London.
Do you cover general building work as well as roofing in Hillingdon?
Yes, we take on both. Given how mixed the housing stock is across the borough, jobs range from full extensions and structural work through to standalone roof repairs or replacements. If you're not sure whether your issue is a roofing job or something more structural, it's fine to describe what you're seeing and we can advise on the likely scope before committing to anything.
Can I fit both a bath and a shower in a small bathroom?
Often yes, depending on the room's dimensions. In tighter London bathrooms we commonly fit a shower over a shortened bath, or a corner shower alongside a bath, rather than losing one fitting entirely. Getting both into 2 to 3 square metres usually means choosing space-saving fittings such as a wall-hung WC with a concealed cistern or a slimline basin, and checking door swing carefully, since an inward-opening door can eat into the only usable floor space once the bath and shower are both in position. We measure and mock up tight layouts before ordering sanitaryware so we can tell you honestly whether both will fit.
Can you handle the whole bathroom renovation, or just parts of it?
We take on the full renovation as one project, strip-out, plumbing, electrics, tanking, tiling and fitting the sanitaryware, coordinated by one team rather than passed between separate tradespeople you'd need to book and manage yourself. If you only need one element, such as retiling an existing bathroom without changing the layout, that sits under our tiling service instead, and we're happy to be clear about which scope suits your project before you commit to either one.
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.
