A bathroom renovation in London involves 7 distinct trades working in a precise sequence. Soraiz Builders coordinates every one of them under a single named project manager, eliminating the scheduling conflicts and miscommunication that cause most renovation delays.
Full Strip-Out and Rebuild
Complete demolition back to the structural substrate. In Victorian and Edwardian properties near roads like Northcote Road in Wandsworth or Argyle Road in Ealing, this stage regularly uncovers original lath-and-plaster walls, cast-iron soil stacks, and lead supply pipes dating to before 1970. Every discovery is reported the same day, with a written cost update before any additional work begins.
Plumbing and Pipework
Supply and waste connections are set during first-fix plumbing, before walls are boarded. Soil pipe positioning has the largest single impact on cost: keeping the toilet in its existing position saves £600–£1,200 compared to moving it across the room. Hot and cold feed routes are confirmed at the survey stage. All drainage complies with Building Regulations Part H.
Waterproofing and Tanking
Soraiz applies a tanking membrane to all wet areas before any tile adhesive is used. In wet rooms, a full waterproofing screed is laid with a calculated fall to the linear drain — minimum cure time of 24 to 48 hours before tiling begins. In Victorian properties, original lath-and-plaster is removed entirely and replaced with moisture-resistant board before tanking. Skipping this step is the leading cause of tile failure within five years.
Wall and Floor Tiling
Tiling accounts for 3 to 5 working days on a standard mid-range renovation. Soraiz works with formats from classic 300×300 ceramics to 1200×600 large-format porcelain and natural stone. Complex layouts — herringbone, feature walls, recessed niches — are priced separately at the quote stage. Silicone detailing at all internal corners and junctions is included as standard, not added as an extra.
Suite and Fixture Installation
Second-fix covers the full suite: bath or shower tray, WC, basin, taps, shower enclosure or frameless glass panel, towel radiator, and all brassware. Soraiz installs client-supplied suites at a fixed labour rate, or sources fittings at trade price where supply is included. Wall-hung fixtures use reinforced noggins built during first fix. All connections are pressure-tested before sign-off.
Electrical and Lighting
All bathroom electrical work is completed by Part P certified electricians. Scope includes LED downlights, extractor fans to Part F ventilation requirements, underfloor heating thermostat wiring, mirror demister connections, and shaver sockets outside the exclusion zone. A Building Control notification is submitted for all notifiable electrical work, and a compliance certificate is provided at handover.
Carpentry and Fitted Storage
Storage is frequently overlooked in bathroom planning, particularly in London flats where the average bathroom measures under 5 square metres. Soraiz builds and fits vanity units, mirror cabinets, built-in shelving, and bespoke panel systems. Wall-hung vanities are fixed with structural mounts into the stud frame or blockwork — not toggle bolts — because a ceramic basin and water demand solid fixing.
6 Types of Bathroom Renovation Soraiz Builders Delivers in London
London’s housing stock produces 6 distinct bathroom renovation contexts. A Victorian terrace in Clapham has fundamentally different challenges from a purpose-built 1970s flat in Greenford, and both differ from a 1930s semi in Chiswick. Each type requires a specific approach to plumbing routes, waterproofing specification, and structural preparation.
Full Bathroom Renovation — Strip to Handover
A full bathroom renovation covers every element from demolition to the final silicone bead. The sequence runs in a fixed order: strip-out, structural repairs, first-fix plumbing, first-fix electrical, waterproofing and boarding, tiling, second-fix plumbing, second-fix electrical, suite installation, finishing, and snagging. Skipping or reordering stages produces failures within two to three years.
Soraiz manages this sequence to a written project plan shared with the client before work begins. Typical London properties: Victorian terraces in Wandsworth (SW18), Edwardian semis in Ealing (W5), 1930s houses near Streatham and Norbury (SW16).
Bathroom Fitting and Suite Installation
Bathroom fitting covers projects where the layout stays broadly the same and the focus is replacing the existing suite, tiles, or both. This is the most common request from landlords and property investors managing properties across Ealing, Hounslow, and Brent. Soraiz offers two approaches: fit-only, where the client supplies the suite; or supply-and-fit, where Soraiz sources fittings at trade price and manages delivery. Both are quoted as fixed prices.
Enquire about bathroom fittingWet Room Installation London
A wet room is a fully waterproofed shower space with no tray, no enclosure, and a floor gradient that drains to a linear or point drain. The floor build-up requires a minimum 75mm screed to achieve the correct fall — existing floor levels must be assessed at the survey stage. Full tanking from floor to ceiling is mandatory, not optional.
Soraiz installs wet rooms with certified waterproofing systems, recessed niches, frameless glass panels, and thermostatic shower valves as standard inclusions.

An ensuite renovation covers two scenarios: renovating an existing ensuite, or converting a box room, large cupboard, or bedroom section into a new ensuite. The conversion scenario requires routing a new waste pipe to the existing soil stack. In a two-storey London terrace, this means running the pipe through the floor void or a duct within the bedroom wall.
Sound insulation between the ensuite and the sleeping area is a detail most contractors omit. Soraiz includes it as standard, because it directly affects daily comfort. Typical properties: loft conversion ensuites in Islington (N1), box room conversions in Chiswick (W4), master bedroom ensuites in Fulham (SW6).
Get an ensuite renovation quoteSmall Bathroom Renovation
The average bathroom in a London purpose-built flat measures between 3.5 and 5 square metres. In that footprint, layout decisions determine whether the room feels usable or cramped. Wall-hung WCs and basins clear 150mm of floor depth and make the room visually larger. A walk-in shower in the corner removes the bath — a decision that works for most London flats where a second bathroom handles bathing separately.
Large-format tiles (600×600 minimum) reduce grout lines and make small walls feel continuous. Recessed niches replace freestanding shelving without losing storage. Soraiz has delivered small bathroom renovations in purpose-built developments across Ealing, Hounslow, and Brent, where sub-5m² bathrooms are the norm.
Traditional Bathroom Renovation — Victorian and Edwardian Homes
Traditional bathroom renovations in pre-1920 London properties require a different specification from modern builds. The original fabric — lath-and-plaster, cast-iron pipework, solid timber joists, and narrow floorboards — demands careful stripping before any new installation begins.
Period-appropriate finishes are achievable with modern materials: concealed cisterns in classic white gloss cabinetry, wall-mounted cross-head taps in brushed chrome or unlacquered brass, subway tile schemes in authentic proportions, and freestanding roll-top baths. The waterproofing behind these finishes is fully modern. The aesthetic is period. The performance is 2026 standard.
How Much Does a Bathroom Renovation Cost in London in 2026?
Last updated: June 2026 — cost data reviewed quarterly against Checkatrade, MyJobQuote, and Soraiz project records.
A bathroom renovation in London costs between £5,500 and £22,000 for most residential projects in 2026. The range is wide because the scope varies substantially: a like-for-like suite replacement in a Hounslow flat is a fundamentally different project from a full wet room conversion in a Victorian terrace in Battersea. London costs run 15 to 20 per cent above the UK national average, driven by higher labour rates and the logistical reality of working in dense urban areas with limited parking and material access.
Bathroom Renovation Cost in London — 2026 Price Guide

| Full mid-range renovation | £8,000–£12,000 | 9–14 days | Victorian terraces, family homes |
| Ensuite creation or conversion | £6,000–£10,000 | 8–13 days | Loft conversions, box rooms |

4 Factors That Move Your Bathroom Renovation Cost
1. Soil Pipe Position
Keeping the toilet where it is saves £600–£1,200 compared to moving it. Moving the soil pipe even 30cm adds a full day of plumbing. Moving it across the room can add three days. This is the first question raised at every Soraiz site survey.
2. What the Strip-Out Reveals
Lead supply pipes, rotten floor joists, and subfloor damage from slow leaks are common in London period properties. Every hidden issue is flagged the same day with a written cost update before any additional work begins.
3. Tile Format and Pattern
Standard 300×300 ceramics cost less to install than 1200×600 large-format porcelain. Herringbone and feature patterns add 20–40% to the tiling labour cost. All pattern choices are priced at the quote stage, not discovered on the invoice.
4. Layout Change vs. Like-for-Like
A like-for-like replacement is the most cost-efficient scope. Moving any fixture connected to waste plumbing adds cost and time. Soraiz maps all drainage at the survey and includes a drainage schematic in the quote for any layout-change project.
Budget Contingency: How Much to Set Aside
Set aside 10% of the quoted price as contingency on any property built after 1970. For Victorian and Edwardian properties — which account for roughly half of all residential housing in inner London boroughs including Wandsworth, Islington, Lambeth, and Hammersmith — 15% is the more realistic figure. Older buildings regularly conceal conditions that a survey cannot identify until walls are opened. This is not a warning that something will go wrong. It is recognition that period properties in London almost always carry surprises.
5 Stages of a Soraiz Builders Bathroom Renovation
From first call to final handover, every bathroom renovation Soraiz completes follows the same 5-stage sequence — managed by a single named project manager throughout. One point of contact means one person accountable for the schedule, the trades, and the outcome.
Free Site Survey and Written Quote
A Soraiz site visit begins with a physical inspection of the bathroom: wall structure, floor substrate, existing pipework routes, and any visible signs of damp or structural movement. In period properties, this inspection includes checking for lath-and-plaster walls and cast-iron soil stacks, which affect the waterproofing specification and tiling schedule.
A written, fixed-price quote is issued within 2 hours of the survey. The quote itemises labour and materials separately, states the project timeline by stage, and identifies any conditions that could affect scope. Nothing changes after the contract is signed without your written agreement.
Fixed price — no hidden extrasDesign Confirmation and Material Selection
Layout options are presented alongside the quote. Where the client has an existing design or has sourced a suite, Soraiz reviews the specification and flags any installation considerations before materials are ordered. Where supply is included, Soraiz sources suite, tiles, and fittings at trade price and confirms lead times — a common cause of project delay that is managed out of the process at this stage.
A written project plan covering each stage, the trades involved, and the daily schedule is shared before work begins.
Strip-Out and First Fix (Days 1–3)
Full demolition is completed first: tiles, suite, flooring, wall board, and any damaged substrate are removed and disposed of. Skip hire is arranged by Soraiz and included in the quote — skip hire in London typically costs £200–£350 and is not added as a surprise line item.
Hidden conditions found at strip-out are reported the same day with photographs. A written cost update is provided before any remedial work begins. First-fix plumbing follows: waste and supply routes are set, soil pipe connections confirmed, and drainage layout agreed. First-fix electrical runs lighting circuits, extractor fan cabling, and underfloor heating cables before boarding begins.
Waterproofing, Tiling, and Second Fix (Days 3–10)
Tanking membrane is applied to all wet areas. In a wet room, a full screed is laid with a calibrated fall to the drain: this cures for a minimum of 24 to 48 hours before tiling begins, and this waiting period is built into the project plan, not discovered as a delay.
Wall and floor tiling follows. Large-format tiles are set out from the centre of the room so cut tiles are symmetrical and positioned in the least visible locations. Second-fix plumbing connects the suite, tests all joints under pressure, and checks shower valve flow rate. Second-fix electrical installs fittings, commissions underfloor heating, and connects the extractor fan.
Finishing, Snagging, and Handover
Silicone sealing, grout finishing, panel fitting, mirror installation, and accessory fixing complete the visual finish. A full snagging walkthrough is carried out with the client before sign-off: every item on the snagging list is resolved before the project is marked complete.
Building Control is notified for all Part P electrical work. The compliance certificate is provided at handover, along with manufacturer documentation for the suite, shower valve, and underfloor heating thermostat. This documentation protects the homeowner at the point of any future property sale.
Part P compliance certificate at handover Workmanship warranty issuedWhat Makes Bathroom Renovation Different in London’s Victorian and Edwardian Homes
Approximately 47 per cent of London’s residential housing stock was built before 1946. Victorian terraces near Northcote Road in Wandsworth, Georgian houses off Upper Street in Islington, and Edwardian semis lining Argyle Road in Ealing all share construction characteristics that alter the bathroom renovation process in ways that a standard specification does not account for.
Lead Pipework and Pre-1970 Plumbing
Properties built before 1970 frequently contain lead supply pipes connecting the mains to internal fittings. Lead pipework must be replaced when a bathroom is fully renovated — not because it is a legal requirement in every case, but because a new bathroom installation is the practical point at which replacement is easiest and least disruptive.
Cast-iron soil stacks — common in pre-1930 London builds — are retained where structurally sound, with push-fit or lead-wiped adaptors connecting new plastic waste runs to the existing iron spine.
Lath-and-Plaster Walls and Tanking
Victorian and Edwardian interior walls are constructed from timber laths covered with lime-based plaster — not the modern cement render or plasterboard that accepts a tanking membrane directly. Applying tanking over lime plaster produces adhesion failure, usually within two to three years.
The correct method is full removal of the lath-and-plaster to the timber stud frame, followed by moisture-resistant board installation, then tanking, then tiling. Soraiz confirms this requirement at the survey stage and includes it in the fixed-price quote.
Conservation Areas and Internal Bathroom Works
London contains over 1,000 designated conservation areas, covering large parts of Islington, Kensington and Chelsea, Wandsworth, and Hammersmith and Fulham. Conservation area restrictions apply primarily to external changes — rooflines, windows, facades, and extensions. Internal bathroom renovation works are not subject to conservation area consent in most cases.
Listed building status is a separate matter: any property with a listed building designation requires a Listed Building Consent application for works affecting the character of the building. Soraiz advises clients to check listed building status with their local council before any structural bathroom work begins.

Converted Victorian Flat — Parsons Green Area
Full renovation · High-spec finish · Noise insulation
A full bathroom renovation in a first-floor converted flat near Parsons Green. The shared waste stack running through the party wall required copper-to-plastic adaptors and noise insulation to prevent sound transfer to the neighbouring flat — a detail specific to London period conversions.
Finish: Full-height 600×1200 grey stone-effect tiles, concealed cistern behind flush access panel, walk-in shower with thermostatic valve and rainfall head, LED mirror with demister pad.
★★★★★
“The attention to detail was impressive — they even insulated the pipes before boarding. The finish is genuinely high quality.”

Victorian Maisonette — Abbeville Road Area
Wet room · Subfloor remediation · Dual-fuel towel rail
A bathroom renovation in a Victorian conversion maisonette near Abbeville Road, Clapham South. The shower tray had been leaking into the subfloor for an estimated 3 to 5 years. Full subfloor remediation, joist treatment, and new structural screed were required before the new installation could begin.
Finish: Wet room specification with linear drain, full-height subway tiles in sage green, wall-hung suite, heated towel rail on dual-fuel setup for year-round use.
★★★★★
“They found the subfloor damage on day one and showed us photos before doing anything. Every decision was explained. We trusted them completely.”

Georgian Terrace — Upper Street Area
Ensuite creation · Period aesthetic · Conservation area
An ensuite renovation in a Georgian mid-terrace near Upper Street, Islington. The property sits within a conservation area — no external works were involved, so no consent was required. A new waste pipe was routed from the first-floor ensuite to the shared soil stack via a concealed duct built within the bedroom wardrobe space.
Finish: High-level cistern, wall-mounted cross-head taps in unlacquered brass, handmade brick-shaped tiles in off-white, solid oak vanity with undermount ceramic basin.
★★★★★
“Exactly what we wanted — period look with modern waterproofing and ventilation behind it. Soraiz clearly understood what we were trying to achieve.”
— [VERIFY: Client name] · MyBuilder · Islington
Edwardian Semi — King Street Area
Full renovation · Enhanced waterproofing · Dual-layer damp barrier
A full bathroom renovation in an Edwardian semi near King Street, Hammersmith. The ground-floor bathroom showed signs of rising damp in the subfloor. A dual-layer waterproofing specification was applied: liquid membrane to walls and floor before moisture-resistant board, providing a barrier against both shower moisture and ground moisture.
Finish: 600×300 warm white wall tiles, charcoal hex mosaic floor, freestanding roll-top bath with shower attachment, period chrome fittings, bespoke painted MDF vanity.
★★★★★
“The team identified the damp issue before we even knew it was there. The fix cost less than we expected and the finished bathroom is exactly right for the house.”
