About this service
What bathroom installation in London actually involves
What a full bathroom installation includes
A full bathroom installation covers considerably more than swapping out a toilet and basin. The scope typically includes a bath or shower tray, WC, basin and vanity unit, mixer taps, shower enclosure or wet room formation, wall and floor tiling, new flooring, all pipework alterations, waterproofing (tanking), lighting, and a heated towel rail. Each element has a correct sequence — get it wrong and you are re-tiling over uncured adhesive or installing a shower valve before the wall is tanked.
London properties add layers of complexity that out-of-area contractors routinely underestimate. Most purpose-built flats built since the 1960s are served by a gravity-fed cold water system with low mains pressure — often insufficient for a thermostatically controlled concealed shower valve. The solution is either an electric shower (which heats water independently and needs only a cold supply) or a booster pump fitted inline. We assess water pressure at the survey stage and advise on the right solution before any sanitaryware is ordered. Buying a pressure-dependent shower valve for a low-pressure flat is an expensive mistake we help clients avoid.
Victorian and Edwardian terraces — a huge proportion of London's housing stock — present a different challenge: aged cast-iron soil stacks. Connecting new sanitaryware to a crumbling soil pipe mid-project causes delays and unexpected cost. We inspect the soil stack at the survey and include any remedial work in the fixed price, so there are no surprises once the old suite is out.
For en-suite installations, we can create a new bathroom from a corner of an existing bedroom. A typical en-suite job involves erecting a stud wall, rerouting a soil pipe to connect into the nearest stack, installing positive-pressure mechanical ventilation (as there is rarely an external wall), and running new hot and cold supplies from the airing cupboard or existing bathroom pipework. Our Gas Safe registered engineers handle all associated hot water work — cylinder upgrades, unvented system adjustments — as part of the same project. We cover all 33 London boroughs and carry 60 Checkatrade reviews and 120 MyBuilder reviews across 180+ verified jobs.
Wet rooms, project management and timelines
Wet rooms have become the preferred choice for smaller London bathrooms — removing the shower tray and enclosure opens up the floor plan and makes the space feel considerably larger. They are also far easier to clean and maintain. However, a wet room is only as good as its waterproofing. We use Schluter KERDI tanking membrane bonded to the substrate before any tiles go on, ensuring that water cannot reach the structural floor or walls regardless of tile or grout condition. In flats with concrete floors, a linear drain is recessed flush into the screed. In properties with suspended timber floors, we assess the structure and typically add a plywood subfloor before tanking. All wet room installations carry a 10-year waterproofing guarantee.
One of the most common frustrations with bathroom renovations is managing multiple trades. We eliminate that problem entirely. Prestige Engineers coordinates the plumber, tiler and electrician (for lighting circuits, extraction and the heated towel rail) from a single point of contact. You deal with one team, one schedule and one fixed price. There is no chasing separate contractors, no gaps between trades and no finger-pointing if something needs rectifying.
On timeline: a standard like-for-like bathroom swap — strip out the old suite, replumb, tile and install new sanitaryware — takes five to seven working days. A new en-suite creation or a full bathroom refurbishment with structural alterations runs seven to fourteen days depending on the scope. We provide a clear pricing breakdown before work starts and aim to restore hot water access each evening during the project so the household is not without a working shower for the full duration.

London bathrooms
Bathroom renovation in London properties
London bathrooms present specific challenges that contractors unfamiliar with the city's housing stock often underestimate. Victorian and Edwardian properties typically have solid brick walls and suspended timber floors — very different from modern cavity construction. Wall fixings, waterproofing details and tile adhesive selection must account for the movement characteristics of old lime mortar walls.
Drainage in older properties is often a network of cast iron pipes with varying falls. Before any bathroom renovation, we inspect the drain condition and soil stack connection to identify any remedial work required before new sanitaryware is installed. Replacing a bathroom and finding a cracked soil stack mid-project is a common source of budget overrun — we identify these issues upfront.
Hard London water (Thames Water supplies most of London at 300+ mg/L hardness) affects grout joint longevity and limescale on showers. We specify appropriate grout sealers and advise on shower head designs that are easy to descale.
Wet rooms in Victorian terraces
Solid ground floors in Victorian terraces allow for wet room drain installation without floor height issues. Suspended timber upper floors require assessment — we may need to add a plywood subfloor before waterproofing. Schluter KERDI system is our standard for tiled wet rooms.
Leasehold flat bathrooms
Many London flats are leasehold. Major bathroom works may require freeholder consent under the lease. We advise on what is likely to need consent and can provide technical specifications for your management company or managing agent.
Listed buildings and conservation areas
Internal bathrooms in listed buildings may require listed building consent for significant alterations. We advise on specification choices that minimise intervention — reversible rather than permanent where possible.
HMO bathrooms
HMO bathrooms require robust sanitaryware and tiling that withstands heavy use. We specify commercial-grade products suitable for HMO environments and can turn around bathroom refurbishments between tenancies.
FAQ
Bathroom installation questions
How much does a bathroom installation cost in London?
Bathroom installation costs in London vary widely by specification and size. A standard bathroom refurbishment (new suite, retile, new flooring) typically costs £3,000-6,000. A fully designed bathroom with quality sanitaryware, feature tiling and bespoke storage runs £6,000-12,000. Wet room conversions including waterproofing and linear drain typically cost £5,000-9,000. En-suite installation in a bedroom with new plumbing supply runs £4,000-7,000. These prices include our own plumbers, tilers and electricians — no subcontracting. Supply costs vary significantly by choice of sanitaryware.
How long does a bathroom installation take?
A standard bathroom refurbishment (strip out, plumbing, first fix, tiling, second fix, decoration) typically takes 7-10 working days. A more complex wet room or en-suite with significant plumbing modifications can take 10-14 days. We aim to restore hot water access each evening during the works. For tenanted properties, we coordinate the schedule with the landlord to minimise disruption to occupants.
Do you supply the sanitaryware or do I buy it myself?
Both options are available. We can supply sanitaryware through our trade accounts at competitive pricing, or work from a supply list of items you have purchased yourself. If you supply the items, we ask that everything is on-site before work starts to avoid delays. We are happy to advise on compatible products and specifications — for example, confirming that a shower valve has sufficient flow rate for your system pressure before you purchase.
Do I need planning permission for a new bathroom in London?
Replacing a bathroom like-for-like does not require planning permission. Converting an en-suite or adding a new bathroom where one did not previously exist is permitted development for most properties. However, if your property is in a conservation area, is listed, or is a leasehold flat, additional consents may be required. Plumbing and electrical work in bathrooms must comply with Building Regulations Part P (electrical) and Part G (sanitation, hot water). Our electricians self-certify Part P compliance.
Can you install a wet room in a London flat?
Yes, but wet rooms in flats require careful waterproofing. We use Schluter KERDI tanking membrane or Wedi board systems to create a fully tanked wet room area, with a linear drain recessed into the floor. In older buildings with suspended timber floors, we assess the structural implications and may need to add a new subfloor. All wet room installations include a 10-year waterproofing guarantee. Leasehold flats may require freeholder consent for works involving structural modifications.
