What a full kitchen refurbishment includes
Strip-out of the existing kitchen, removal of old units, plumbing and electrics. Full first-fix plumbing for sink, dishwasher, washing machine, hot and cold runs to island if relocating. Full first-fix electrics to current Part P standards by an NICEIC-registered electrician — new circuits where existing capacity is insufficient. Plastering and skim, splashback waterproofing, floor preparation. Installation of supply-only kitchens (Howdens, Magnet, Wren, B&Q, IKEA) or bespoke kitchens (Plain English, deVOL, Naked Kitchens, our own joiners). Worktop templating and installation (granite, quartz, solid wood, laminate). Appliance installation and commissioning. Tiling, painting, sealing.
What a full bathroom refurbishment includes
Strip-out, soil and waste pipe replacement where required, full retiling, tanking of wet areas, installation of bath, shower enclosure, WC, basin, towel rail, ventilation. Underfloor heating where appropriate (electric mat under tile is standard for London bathrooms). Recessed shaver sockets, mirror demister pads, lighting on a separate isolator. We work with most major UK suppliers (CP Hart, Bathroom Heaven, Wickes, Soak.com) but can also source bespoke fittings on request.
Typical timelines
A standard kitchen refurbishment runs 4 to 7 weeks. A standard bathroom runs 2 to 4 weeks. Bespoke kitchens with imported worktops can extend to 9 to 12 weeks because of supplier lead times. We coordinate all delivery dates and store materials safely off-site if required.
Why work with one contractor on a kitchen or bathroom
The two most common ways a London kitchen or bathroom goes wrong are interface issues — the plumber finishes before the tiler, the tiler sees a misaligned drain, work stops, dates slip. We control every trade in-house, so the plumber, tiler, electrician and joiner are all on the same payroll and the same daily plan. The only external supplier is the kitchen or bathroom showroom delivering the units.
Kitchen extensions in London
A kitchen extension combines a side-return or rear extension with a full kitchen refit. The most popular format in our East and South East London catchment is a side-return on a Victorian terrace, opening into the existing rear addition and creating a single 25 to 40 square metre kitchen-dining-living space. Every estimate is individual: the price depends on size, glazing, kitchen brand and finish. The scopes we build:
- side-return extension only (no kitchen fit-out);
- side-return with a Howdens or Magnet kitchen;
- side-return with a bespoke kitchen (deVOL, Plain English, KRAMAN joiners);
- wrap-around extension with a premium kitchen;
- open-plan kitchen-living-diner with a structural opening only (no extension).
For side-return extension options and planning permission see our house extension page. The kitchen fit-out itself typically runs 4 to 7 weeks once the extension shell is complete, including templating, worktop fabrication, appliance installation and tiling. KRAMAN handles the entire programme as one project — extension build, kitchen install, decoration and snagging — under one contract and one project manager.
Bathroom refurbishment in London
Our bathroom work covers supply and install of all fixtures, plus all plumbing, electrical, tiling and decoration. Every estimate is individual and depends on the room and the fittings you choose. The programme for each type of bathroom:
| Bathroom type | Programme |
|---|---|
| Compact en-suite (3 to 4 m²) | 2 to 3 weeks |
| Standard family bathroom (5 to 7 m²) | 2 to 4 weeks |
| Master bathroom with bath and walk-in shower | 3 to 4 weeks |
| Wet room conversion (full tank, level floor) | 3 to 4 weeks |
The cost drivers are: tile choice (large-format porcelain costs more than standard ceramic), brassware brand (Hansgrohe, Vola or Crosswater cost more than Hudson Reed or Wickes), underfloor heating (electric mat under tile), structural changes such as relocating the soil stack, and waterproofing complexity (a wet room needs full tanking and level floor formation, which costs more than a shower enclosure).
Frequently asked questions
Can you supply the kitchen or do I supply it?
Either works. Most clients use a showroom for design and supply (Howdens, Magnet, deVOL) and we install. We also have our own joiners who build bespoke kitchens to spec.
How disruptive is a bathroom refurbishment?
Very. There is no plumbing in the bathroom for the duration of the strip-out and first fix (typically week 1 of a 3-week schedule). We can install a temporary shower in another room if the house has only one bathroom.
Do you guarantee the work?
Yes. KRAMAN gives a 24-month workmanship warranty on all kitchen and bathroom work. Manufacturer warranties on appliances and fittings sit on top.
How much does a kitchen extension cost in London?
Every estimate is individual. The price depends on the size of the side-return or wrap-around extension, the glazing, the kitchen (Howdens or Magnet, or bespoke from deVOL, Plain English or our own joiners) and the finish. We price the extension and the kitchen together after a free site visit.
How much does a bathroom refurbishment cost in London?
Every estimate is individual. The price depends on the room (a compact en-suite, a family bathroom, a master bathroom with bath and walk-in shower, or a wet room with a tanked floor), the tiles and brassware, underfloor heating and any changes to the soil stack. We price each bathroom after a free site visit.
How long does a kitchen refurbishment take?
A standard kitchen refit (no extension) runs 4 to 7 weeks. A bespoke kitchen with imported worktops can extend to 9 to 12 weeks because of supplier lead times. A kitchen extension (side-return plus kitchen install) runs 10 to 16 weeks in total.
Do I need planning permission for a kitchen extension?
Most side-return kitchen extensions on terraced houses fall under permitted development (no planning fee). Wrap-arounds and extensions in conservation areas need full planning permission. See our <a href="/services/house-extension-london/">house extension page</a> for the full rules.
