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.
Lambeth overview
Bathroom Renovation in Lambeth
Clapham, Brixton and Pimlico-adjacent streets with a healthy mix of refurbishment volume and manageable competition. Lambeth falls well within the South London ground Lian Construction covers on a regular basis. For bathroom renovation work in Lambeth, that local knowledge means fewer surprises once work is on site and a team that already understands the borough's typical property stock.
Lambeth's residential streets, particularly around Clapham, Brixton and the areas bordering Pimlico, are dominated by housing stock typical of inner south London: Victorian and Edwardian terraces, many long since split into flats and maisonettes. Alongside these sit purpose-built mansion blocks from the early twentieth century and pockets of post-war and ex-local authority housing, a pattern common across much of inner London where original street layouts survived but individual buildings were subdivided, extended or replaced over the decades.
This mix means refurbishment work in the area rarely follows one template. A single street can include a converted terrace flat with shared access and party walls, a self-contained Victorian house, and a mid-century block, each with different structural quirks, service runs and access constraints. Older properties commonly bring the issues associated with ageing housing stock: outdated wiring and plumbing, solid or poorly insulated walls, and roofs that have had several past repairs rather than one full replacement. A contractor working here needs to be equally comfortable adapting to a period conversion as to a more straightforward modern refurbishment.
The blend of refurbishment volume and manageable competition around Clapham, Brixton and the Pimlico-adjacent streets reflects an area with steady demand but without the sheer density of contractors chasing every job that you'd find in some more central boroughs. A large share of the housing stock is ageing and in continuous need of upkeep, upgrading or conversion work, which keeps a fairly constant flow of refurbishment, repair and roofing enquiries coming from both owner-occupiers and landlords.
For homeowners, this generally means it's possible to get a contractor booked in and a quote turned around without the long waiting lists seen in busier parts of London, though good tradespeople are still in demand and it pays to book ahead for larger projects. For landlords managing flats or converted houses in the area, the practical implication is similar: routine maintenance and larger refurbishment work can usually be scheduled without excessive delay, but it's still worth getting multiple quotes and checking availability early, particularly for work that needs to happen between tenancies or during void periods.

How bathroom renovation fits with other trades
A bathroom renovation rarely stays entirely within the bathroom walls. Moving a waste pipe sometimes means lifting floorboards in the room below or accessing a void through a neighbouring room, and rerouting a soil stack in a converted flat can affect a shared wall or a floor void serving the flat below, which needs planning around and, in some cases, notice to a neighbour rather than discovering the constraint once floorboards are already up. Where the property is part of a wider refurbishment, we sequence the bathroom alongside the rest of the programme so first-fix plumbing and electrics happen at the same stage as the rest of the house, rather than as an isolated job that holds up decoration and second-fix work elsewhere in the property. Tiling within a bathroom renovation is delivered to the same standard as our dedicated tiling service, since the two are effectively one job in practice and the finished waterproofing depends on the tiling and the tanking beneath it being coordinated properly, but where a client only wants the existing bathroom retiled without a full refit, that smaller scope sits under our tiling service instead rather than being priced as a full renovation. We also coordinate with plasterboard repair where a wall needs opening up for new pipework or cabling and making good afterwards to match the surrounding finish, and with leak repair where a bathroom renovation follows water damage that needs the affected structure properly dried out and reinstated before the new suite goes in, rather than building a new bathroom on top of a problem that hasn't actually been resolved. Having one team responsible for the whole sequence avoids the common problem of a tiler being booked before the plumber has confirmed final fitting positions.
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.

Signs to look for
Do you need bathroom renovation in Lambeth?
You want a walk-in shower or wetroom instead of a bath, which needs the floor built to falls rather than just retiled.
The bathroom floor feels uneven, spongy or has a visible dip, pointing to a joist or subfloor issue beneath the existing finish.
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.

Questions
Bathroom Renovation questions in Lambeth
How quickly can Lian start bathroom renovation work in Lambeth?
Lambeth 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 Lambeth?
Yes. Lambeth falls within the area Lian Construction serves across Greater London.
Do I need planning permission for an extension or loft conversion in the Clapham or Brixton area?
It depends on the property. Many extensions and loft conversions fall under permitted development, but this isn't automatic, especially for flats and maisonettes rather than houses, and can be affected by previous alterations to the building. Some streets in inner London boroughs also sit within conservation areas, which can bring extra restrictions. We'd always recommend checking with the local planning department or a planning consultant before committing to a design, rather than assuming permitted development rights apply.
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.
