View Full Bathroom Renovation Guide →Bathrooms in Central London homes are often the most constrained rooms in the building: tight footprints, ageing soil stacks, awkward joist directions, limited drainage falls and strong expectations around finish and durability.
Start with the existing floor, drainage, water supply and ventilation route. For a flat, check shared services, the lease and freeholder requirements. For a listed home or work affecting external fabric, establish the property-specific approval requirements. Conservation-area status alone does not make every internal bathroom alteration a planning application.
Our team delivers family bathrooms, wet rooms and en-suites across Marylebone, Mayfair, Belgravia, and Knightsbridge and the wider Central London area, coordinating design, plumbing, joinery, tiling and final snagging under one programme.
From a compact cloakroom WC to a hotel-standard master en-suite — we design and build every bathroom type that London homes demand.
Full-size bathroom with bath, separate shower, WC, basin and storage. The centrepiece of most London homes.
Shower room adjacent to the bedroom — walk-in shower, wall-hung WC, vanity basin and heated towel rail. Compact but complete.
Fully tanked level-access shower room with gradient floor to a linear drain. Sleek, minimal and accessible — ideal for loft en-suites and contemporary interiors.
Compact ground-floor WC with basin, vanity and feature tiling. Small space, big impact — often the first bathroom visitors see.
A structured design-and-build process that eliminates guesswork and protects your budget.
We measure the existing bathroom, photograph it from every angle, check the plumbing routes (waste positions, water supply, soil stack location) and assess the floor structure for underfloor heating and any stone-bath loading requirements. We discuss your brief — shower vs bath preference, storage needs, aesthetic direction, must-have brands or finishes — and produce a 3D concept design with two to three layout options. Materials are selected from physical samples at our Finchley Road studio.
Existing bathroom stripped out — old tiles, sanitary ware, plumbing and flooring removed. Walls checked for damp and repaired where needed. New plumbing roughed in to the exact positions specified in the design: hot and cold feeds, waste connections, shower valve position, toilet waste and underfloor heating loops. Electrical first fix for lighting circuits, heated mirror, extractor fan and any shaver sockets. For wet rooms, the tanking membrane is applied and tested before tiling begins.
Our specialist tilers lay the wall and floor tiles — whether that's large-format porcelain, handmade Zellige, marble mosaics or encaustic cement tiles. Tile cuts around valves, niches and corners are precise and consistent. Sanitary ware installed: wall-hung WC with concealed cistern, basin on vanity or wall-mounted, bath (freestanding or built-in) and shower enclosure or wet room screen. Brassware fitted — shower valves, taps, towel rails and accessories.
Light fittings, mirrors, glass screens, towel rails, toilet roll holders and all accessories fitted. Silicone sealing around baths, showers and basins. Underfloor heating commissioned and tested. Full clean, snag inspection and client walkthrough. We hand over with all product warranties, care guides (particularly for natural stone) and a 12-month defects liability guarantee.
A typical bathroom renovation in London costs £10,000–£30,000 excluding VAT. All tiers include design, plumbing, electrics, tiling, sanitary ware, brassware and accessories.
What separates a Hampstead Renovations bathroom from a plumber with a catalogue.
Where included in the design scope, visualisation can help compare the layout, tile pattern, brassware and lighting. Agree the drawings, samples and revision allowance before design work begins.
Agree the tile layout, cuts, niches, trims and grout joints before installation. The substrate, waterproofing system and setting-out determine how the chosen finish is delivered.
The accepted quotation identifies design, removal, plumbing, electrics, waterproofing, tiling, fittings and making-good where included. Check allowances, exclusions and the process for variations before strip-out.
Confirm the selected sanitary ware and brassware, supplier quotation, availability and delivery responsibilities before ordering. Any trade saving must be confirmed for the actual products.
Underfloor heating can be considered where the floor build-up, electrical supply and agreed specification allow it. Confirm the system, controls and commissioning requirements in the quotation.
Specify the waterproofing system, falls, drain connection and junctions together. Installation, inspection and curing must follow the selected system before the tiled finish is completed.
A wall-hung WC, basin or vanity needs suitable support, service connections and maintenance access. Select the arrangement for the actual wall and floor construction.
Recessed shower niches, mirrored cabinets, under-vanity drawers and towel storage designed into the bathroom architecture — not bolted on as afterthoughts.
In Victorian and Georgian homes, we design bathrooms that respect ceiling heights, proportions and sightlines — using materials that acknowledge the property's heritage character.
Layered bathroom lighting: recessed downlights, backlit mirrors, niche lighting and dimming circuits designed to create both bright task lighting and relaxing ambient mood.
Electric or wet-system heated towel rails specified as part of the design — positioned for maximum convenience and integrated with the heating controls.
Illustrative arrangements to discuss during design, not records of completed projects. The room dimensions, services and specification need to be checked for your home.
Compare the bath and shower clearances, screen movement and route to the basin. Check the floor, drainage and hot-water supply before committing to the arrangement.
Resolve the floor build-up, drainage falls and waterproofing together. A level-access proposal depends on the existing construction and available drainage route.
Plan the shower-over-bath, basin and storage around the household’s needs. Allow access to valves and traps, and show how doors and drawers will open.
