Bathroom renovation in North West London

Bathroom renovation in North West London conversions and mansion flats — tanking, extract and compact layouts, from a Hampstead office.

Bathroom renovation in North West London is a water problem before it is a finishes problem. Converted Victorian and Edwardian houses have timber intermediate floors, uneven joists and soil stacks that sit a long way from the room you want as an ensuite. Purpose-built mansion flats in St John's Wood, Maida Vale and Swiss Cottage have shared drainage, compact footprints and a neighbour below the waste. A renovation that treats tanking, falls and extract as afterthoughts will leak, stain or stay damp — whatever the tiles cost.

Hampstead Property Services Group renovates family bathrooms, shower rooms and ensuites from a Finchley Road office. The work is a coordinated fit-out: measured survey, layout, waterproofing to a documented system, first and second fix, tiling, sanitaryware, mechanical extract and a watertightness check before handover. We do not drop in a catalogue suite. The room stays as the building planned it unless the stack and the extract will honestly support a change.

Internal bathrooms in Hampstead, West Hampstead, Belsize Park and Kentish Town conversions are ordinary: no window, a long duct run, a door that opens the wrong way for a shower. Compact ensuites in mansion flats have the opposite problem — a sash onto a lightwell, but no space for a bath and a basin without losing the door swing. Half-landing bathrooms in terraces are a third type: the stack is on the party wall and the room is whatever is left. All three can be excellent bathrooms if waterproofing, ventilation and drainage are solved in that order.

Wet rooms are specified only where the floor depth and the waterproofing system will take them. A Victorian conversion rarely has the build-up of a new-build slab. We will not draw a level-access wet room onto joists that cannot accept the fall. A pump is a last resort, written into the proposal if it is the only way the layout works, not hidden as a day-two extra.

We survey in the room. Concealed wastes, previous leaks, failed plywood under a tray and extract that dies in a void only show when you look. A written layout and specification follow the visit. Strip-out does not start until long-lead sanitaryware and tiles are dated. We do not quote bathroom renovation in Hampstead or anywhere else from photographs.

Who bathroom renovation in North West London is for

The work is for owner-occupiers and landlords in the same North West London stock as our kitchens: converted flats, mansion blocks and family houses. Typical instructions are a single family bathroom, a shower room replacing a failed suite, an ensuite in a former dressing room or box room where the building will accept it, or two bathrooms in one programme so the house is not opened twice.

Waterproofing on timber intermediate floors is not optional. We tank wet areas to a documented system. Paint-on afterthoughts over boarded floors are how the flat below gets involved. In a mansion block we isolate, test, and do not cut into another demise without the building's process.

Facts that shape bathroom renovation in North West London

Checkable facts — office, councils, conservation dates and the housing stock — not a brochure.

    Hampstead Property Services Group Limited (company no. 17404557) renovates bathrooms from Unit 3 Palace Court, 250 Finchley Road, London NW3 6DN.
  2. 02
    Converted Victorian and Edwardian houses in Hampstead, West Hampstead, Belsize Park and Kentish Town typically have timber intermediate floors — tanking is a documented system, not a paint-on afterthought.
  3. 03
    Purpose-built mansion flats in Maida Vale date mainly from the 1890s–1910s; bathrooms sit on stacked wastes over a neighbour.
  4. 04
    Highgate Conservation Area was designated on 21 December 1967 and is split between Camden and Haringey; the skip licence follows the borough on the address.
  5. 05
    The Queen's Park Estate cottages were built from 1875 by the Artizans', Labourers' and General Dwellings Company; Westminster's Estate conservation area is a separate map from Brent's Queen's Park Conservation Area.
  6. 06
    Internal bathrooms without a window need mechanical extract with a clear route to outside. We will not leave a room dependent on a fan that dumps into a void.
  7. 07
    A Victorian conversion rarely has the floor build-up of a new-build slab. Level-access wet rooms are specified only where the joists will take the fall.
  8. 08
    Lord's Cricket Ground affects access on St John's Wood streets on match days; bathroom crates often go up the stair, not in the lift.
  9. 09
    Leasehold flats usually need a licence to alter if wastes move or extract is cut through a common void. Consent is the freeholder's, not ours.

What has to be right before the tiles

Bathroom renovation in this housing stock fails from water, air and the stack — not from the choice of brassware.

  1. 01

    Waterproofing

    Timber floors in conversions and stacked mansion flats need tanking as a system, with falls that actually drain. A coat of tanking paint over boarded floor is not a system. This is the decision that protects the room below.
  2. 02

    Extract

    Internal bathrooms cannot rely on a window that does not exist. Duct routes through common parts, roof voids or a conservation elevation are agreed before we open up. We will not punch an insensitive grille through a principal front as a convenience.
  3. 03

    Drainage

    Layout follows the stack that exists. Moving a WC a long way, or forming an ensuite that cannot reach a soil pipe without cutting another demise, is often the item that is not possible. Pumps are last resort, written down if needed.
  4. 04

    The room as found

    Door swings, chimney breasts, half-landings and out-of-square walls decide whether a bath, a shower or both will fit. We survey before we specify sanitaryware. Concealed leaks and failed trays only show in the room.

Typical bathrooms we renovate

Family bathrooms, compact mansion-flat rooms, shower rooms, ensuites and half-landing stacks — each written to the building it sits in.

  • A principal bathroom — honed marble walls, a stone oval bath and a brass floor tap

    Family bathrooms

    A bath, a separate shower where the plan allows, a basin and a WC in village houses and family houses toward the Heath, Highgate, Muswell Hill and the Suburb. Weight, floor build-up and extract on the elevation are recorded before a stone bath is ordered.

  • A compact ensuite in a London mansion flat — dark limestone, chrome taps and a lightwell sash

    Compact mansion-flat bathrooms

    Original rear rooms on risers in St John's Wood, Maida Vale and Swiss Cottage. A short bath or a shower, a basin, a sash onto a lightwell. Lifts often will not take a bath crate; the stair is the working assumption until we measure. Licence to alter is ordinary if wastes or extract move.

  • A walk-in shower lined in book-matched marble, with a brass rain head

    Shower rooms

    A replacement for a failed suite, or a second room where a bath is not needed. Frameless screens and stone trays still need a substrate and a fall. We do not treat a shower as a simpler bathroom; the waterproofing is the same work.

  • A shower wall of handmade blue-green metro tiles with a brass niche

    Ensuites in conversions

    Former dressing rooms and box rooms in Hampstead, Belsize Park and West Hampstead houses. Possible where drainage can reach a stack without damaging a principal room, and extract can be routed without an insensitive grille. Some rooms cannot take a shower without a pump; we will say so at survey.

  • A compact ensuite in a London mansion flat — dark limestone, chrome taps and a lightwell sash

    Internal bathrooms

    No window, a long duct, a door that fights the shower tray. Common in conversions. Mechanical extract with a clear route to outside is not optional. We will not leave the room dependent on a fan that dumps into a void.

  • A walk-in shower lined in book-matched marble, with a brass rain head

    Half-landing stacked bathrooms

    The West Hampstead and Kentish Town type: the soil stack is on the party wall and the room is the remainder. Layout follows the stack. Moving the WC a long way is often the item that is not possible without work we do not do.

Conversion bathrooms, mansion flats and family houses in North West London

What a typical bathroom renovation includes

The list is the core of a typical instruction. The written proposal after survey is the contract scope.

  • Measured survey of the existing bathroom, soil stack, extract route, floor build-up and waterproofing as found
  • Layout for family bathrooms, shower rooms, compact ensuites and internal rooms, including door swings and access
  • Strip-out, protection of floors and common parts, and licensed waste removal
  • Tanking and waterproofing to wet areas to a documented system, not a paint-on afterthought, especially on timber intermediate floors
  • Falls, trapped wastes and drainage alterations to existing stacks where the building allows
  • First- and second-fix plumbing, including concealed cisterns, thermostatic showers and client-supplied sanitaryware
  • Electrical work for lighting, extract, shaver supplies and underfloor heating circuits, notified where the regulations require it
  • Tiling, flooring within the bathroom envelope, and installation of sanitaryware and brassware specified as products, not brand partnerships
  • Decoration of the envelope, seals, and a watertightness check before handover
  • Coordination with neighbours, freeholders and managing agents in mansion blocks where drainage or extract is shared
  • A written snagging pass and care notes for seals, stone and coatings

How a bathroom renovation programme runs

  1. 01

    Survey

    We record the existing bathroom, the stack position, extract route, floor build-up and any listed or conservation constraints on external grilles. Concealed wastes and previous leaks are looked for, not assumed away. No layout is started from photographs.
  2. 02

    Layout and specification

    You get a layout that fits the room you have, a specification for sanitaryware, brassware and finishes, and a note of anything that needs the freeholder, building control or a pump. Items that the stack cannot serve are taken out of the drawing, not left as a hope.
  3. 03

    Lead-in

    Sanitaryware, tiles and any stone are ordered against the approved layout. We do not start strip-out until long-lead items have confirmed dates, so the room is not left open waiting for a tap.
  4. 04

    Strip-out, tanking and first fix

    The room is stripped, substrates prepared, waterproofing installed to a documented system, and plumbing and electrics first-fixed. In mansion blocks we agree hours and common-parts protection with the building in advance. This is the stage that determines whether the bathroom lasts.
  5. 05

    Second fix and finishes

    Tiling, sanitaryware, brassware, glass and decoration follow in sequence. Wastes and showers are tested before the room is signed off. Variations are written, not verbal.
  6. 06

    Handover

    A snagging walk-through, care instructions for seals, stone and coatings, and a clean room. Outstanding items are listed in writing. Final account follows the agreed specification.

How a North West London bathroom is specified

Sanitaryware and brassware are specified as products, not as brand partnerships. Concealed cisterns, thermostatic showers, stone or ceramic trays and tiled wet walls are ordinary items; they still need a substrate that can take them. A stone bath is a weight and access problem in a conversion stair as much as it is a finishes choice.

Underfloor heating, where used, is treated as an electrical circuit and a floor-build-up problem, not as a brochure extra. In a conversion the available depth often decides whether it belongs. We will say so at survey rather than thin the insulation to make it fit.

Drainage alterations stay within the existing stacks wherever the building allows. Pumps are a last resort and are written into the proposal if they are the only way the layout works. Tiling over existing tiles is not the default; failed adhesive and trapped moisture in this housing stock make it a false economy.

What bathroom renovation in North West London costs

We do not publish a price list for bathroom renovation in North West London. Timber floors in a Hampstead conversion, a stacked mansion-flat bathroom in Maida Vale, and a family bathroom in a Highgate house are different jobs. Floor depth, the stack, extract and whether a licence to alter is needed change the figure.

The written proposal after a visit is the price. It covers tanking as a documented system, first and second fix, tiling, sanitaryware as specified products, mechanical extract and a watertightness check. We do not quote a suite from a photograph. Telephone 020 7101 3168.
