Full project management in Kensington and Chelsea
What a full bathroom renovation involves
A full bathroom renovation in Kensington and Chelsea begins with a complete strip out — removing the existing suite, tiles, floor covering and redundant pipework back to the substrate. We then assess the floor void, joist direction and existing waste runs before committing to the new layout. This matters particularly in Kensington and Chelsea properties where the Georgian and Victorian stucco terraces, mansion flats and mews properties.
The first fix stage covers replumbing of hot and cold supply connections and rerouting the waste stack where required. We install the bath or shower tray, connect the WC and basin, and run all supply lines to the correct terminations before the walls are closed up. Waste pipe gradients are checked to Building Regulations requirements to prevent siphonage and odour ingress.
Wall preparation for tiling begins with tanking and backer board installation on any walls receiving tile. This is critical in wet zones — standard plasterboard is not a suitable substrate for tiled shower enclosures, regardless of how the tiles are fixed. We use cement backer board or a dedicated wet wall system throughout the wet zone and apply a waterproof tanking slurry behind all shower and bath areas before any tile adhesive goes on.
Tiling is completed by our in-house tiling team, not subcontractors. We set out from a datum line, cut around pipe penetrations cleanly, and finish all external corners with matching profiles. Grout and silicone colour selections are agreed with you before works start. All movement joints are silicone-filled — never grouted — to allow for natural building movement.
London property considerations
Bathroom renovation in London properties
London properties present specific challenges that differ from newer housing stock elsewhere in the country. Victorian terraces — common across Kensington and Chelsea — typically have shallow floor voids with floor joists running front to back of the property. This constrains drain routes significantly: a new shower waste may need to connect back into the existing stack rather than taking a direct fall to an external gully, and the drain position relative to joists must be planned before the floor is opened up.
For wet rooms in upper-floor flats, the weight of a wet room former differs from a standard shower tray and a structural assessment may be warranted before committing to a full floor screed. We check joist sizes and spans before specifying the build-up, and we use lightweight wet room formers where floor loading is a concern.
London flats in leasehold buildings require notification to the building management company before any work that affects shared services, drainage stacks or structure. We advise on this as part of the pre-works consultation. If the property is in a conservation area or is listed, any new external vent openings — for an extractor fan, for example — may need prior approval before drilling begins.
Part P electrical compliance is non-negotiable for any bathroom renovation that includes new electrical circuits or work within the defined zones around a bath or shower. Zone 0 is inside the bath or shower itself, Zone 1 is the area directly above, and Zone 2 extends a further 600mm outward from the bath or shower edge. Any new wiring, socket, extractor or light fitting within these zones must be installed by a registered Part P electrician and the work notified to the local authority.
Prestige Engineers hold Part P registration and carry out all bathroom electrical works in-house. This covers extractor fans on timers, heated towel rail connections, shaver sockets, illuminated demisting mirrors and underfloor heating thermostats. All work is certificated and notified on completion — you receive the electrical installation certificate as part of the project handover pack.
We do not use subcontractors for electrical works. The same team that manages the plumbing and tiling coordinates the first and second fix electrics, which eliminates the programme delays and responsibility gaps that arise when trades are brought in separately.
Options for your space
Bathroom types for Kensington and Chelsea properties
Classic all-in-one bathroom
Bath, WC and basin in a single room. The standard layout for family homes across Kensington and Chelsea. We can retain the bath footprint or reconfigure to gain storage or a larger shower enclosure within the existing space.
Wet room (level access shower)
A fully waterproofed room with a level-access shower floor and no tray or screen threshold. Requires full tanking of all walls and floor, and careful drain positioning relative to the floor joists. Popular for accessible bathrooms and premium finishes.
Shower room only
Removing the bath and installing a walk-in shower is one of the most popular space-saving conversions in London flats. A properly tiled shower enclosure with a quality tray outlasts a bath recess and frees up significant floor area in smaller rooms.
Pod shower enclosures
Prefabricated shower enclosures with factory-finished walls can be installed faster than a full tiled wet room and suit rental properties where speed of installation and ease of maintenance are priorities. Less customisable than tiling but a practical mid-range option.

Common questions
Bathroom renovation Kensington and Chelsea: frequently asked
How long does a bathroom renovation take in London?
A standard bathroom renovation in London typically takes 1 to 2 weeks from strip out to final finish. Wet rooms may take slightly longer due to the required drying time for the waterproof membrane before tiling can begin. For tenanted properties, factor in that the property will be without a bathroom during this period — we recommend coordinating the work between tenancies where possible.
How much does a bathroom renovation cost in London?
Bathroom renovation costs in London vary by scope and finish. A basic refresh with a new suite and tiling typically costs between 3,000 and 5,000 pounds. A mid-range full renovation including replumbing, tiling and electrical works runs from 5,000 to 8,000 pounds. A premium wet room or luxury finish with underfloor heating and high-end materials can reach 8,000 to 15,000 pounds or more. We provide a fixed quote after a site visit.
Do I need planning permission to renovate my bathroom in London?
Planning permission is generally not required for an internal bathroom renovation. However, listed buildings and properties in conservation areas — both common across London — may require consent for any new external vent openings. If your property is a leasehold flat, you should notify your building management company before works begin. Our team can advise on any consents relevant to your specific property.
Can you renovate a bathroom in a tenanted property?
Yes. We regularly carry out bathroom renovations in tenanted London properties. Coordination with tenants is essential — the property will be without a working bathroom during the works. We provide clear daily progress updates and aim to minimise disruption. For landlords, we can also issue all relevant certificates including Part P notification on completion.
