Wet rooms and en-suites in Bloomsbury
Where a Bloomsbury townhouse is still a single house, or a flat takes a whole floor of one, there is often room to carve an en-suite from a bedroom or landing, or to turn a tired family bathroom into a walk-in shower or wet room. The key to any of these is proper tanking, so we fully waterproof the floor and walls before a tile goes down, then form falls to the drainage and fit reliable ventilation. Get the waterproofing right and a bathroom in a period home lasts for decades.
Drainage is the real challenge in these older WC1 properties, where existing pipe runs and floor levels were never designed for a modern shower. We plan waste routes carefully, sometimes raising floors or using pumped systems where gravity will not cooperate, and add underfloor heating and heated towel rails to keep a solid-walled period home warm. Every layout is worked out to suit the room, not forced from a showroom plan.
Housing in Bloomsbury
Roughly 14,890 dwellings sit on the valuation list for Bloomsbury. 3% are houses and 97% flats, and by age 49% predate 1919, 13% are interwar and 37% post-war. Most homes here are flats, and a bathroom in a flat in Bloomsbury sits over a neighbour's ceiling, so it is tanked before tiling and a moved WC needs the freeholder's licence.
Bathrooms in newer Bloomsbury blocks and older houses need different surveys
12% of Bloomsbury homes were built in 2000 or later, and a bathroom in one of those flats is likely to sit on a concrete slab, with wastes cast in or run through a shallow screed. Moving the shower there is limited by the depth available for a fall rather than by timber joists, and a raised floor or a pumped waste may be the only way to put a walk-in shower where the bath was. Ask the managing agent for the as-built drainage drawings, because they show where the stacks and any cast-in pipes run before a floor is broken out.
In the 49% of Bloomsbury homes built before 1919 the question is the opposite one. The floor is timber, and the risk is the joists: notching them for a new waste across the span weakens them, and an old plumbing repair may already have done so. We lift boards along the proposed waste route at survey, so the route runs with the joists where it can and the structural engineer we appoint sees any that need strengthening before the tanking and tiles hide them for good.
Space-saving bathrooms in Bloomsbury flats
In Bloomsbury's mansion-block flats, bathrooms are often small and boxed in by the building's structure, so clever layout matters more than square footage. Wall-hung sanitaryware, walk-in showers and slim fittings free up floor space and make a compact room feel larger. We plan the plumbing and ventilation around what the flat allows, and because you are usually above another home, we pay close attention to sound insulation and reliable waterproofing to protect the flat below.
Leasehold rules shape bathroom work in these blocks, so moving a soil stack or altering drainage can need the freeholder's licence to alter and the managing agent's sign-off, and we coordinate that for you. New circuits and work close to the bath or shower are notifiable under Part P, so they are certified by a registered electrician or notified to building control as part of the job. Whether it is a single en-suite or a full family bathroom, we deliver a watertight, well-ventilated room that respects both the building and the neighbours.

FAQ
Frequently Asked Questions about Bathroom Renovation Bloomsbury
What happens to the bathroom renovation price if the scope changes in Bloomsbury?
Changing the scope of bathroom renovation in Bloomsbury produces a written variation before anything else happens, priced against the original figure within £6,000 to £20,000 or more (indicative). The commonest cause is upgrading a finish once the WC1 space is open, which is simple to cost. A layout change is different, because a timber floor over the room below decides how the wet area is built. GS Renovation rebooks Camden Council building control inspections where needed.
Can you fit a wet room in my Bloomsbury flat without leaks reaching the flat below?
Yes. The answer is thorough tanking. In a Bloomsbury mansion flat we fully waterproof the floor and walls, form correct falls to the drain and fit good ventilation before tiling, which protects the home beneath yours. We also check the lease, as altering drainage often needs the freeholder's licence to alter and managing-agent approval, and we coordinate that before starting.
How long will our Bloomsbury flat be without its bathroom?
Allow 10 to 15 working days for a full refit. Where the flat has only one bathroom, it is out of use for almost all of that. Strip-out, first fix, tanking before tiling, tiling and fitting run in order and cannot usefully overlap. Arranging a gym membership or a nearby stay for the wet stages avoids a difficult fortnight.
How is an internal bathroom in a Bloomsbury flat ventilated?
By a fan ducted to outside, as Part F requires. An internal room has no window, so the duct runs through the ceiling void, and the joist direction decides whether it can reach an outside wall. In a listed building a new vent on the elevation may need consent. Sometimes an existing opening or a shaft within the building is used with the freeholder's agreement.
Will a new shower have good pressure in my Bloomsbury flat?
It depends on how hot water reaches it. A combi boiler gives mains pressure but shares flow between outlets, and a gravity cylinder in an older block may give very little. Where the block has communal hot water, the building's system sets the pressure. The flow is measured at survey, so the right shower valve is fitted before the walls are tanked and tiled.
Can the upper floor of a Bloomsbury Georgian house carry a freestanding bath?
It can once someone has looked at the timbers under it. Full of water, a freestanding tub puts a heavy load through small feet, and upper-floor joists in Georgian houses were often cut into for later plumbing. With boards lifted, their depth and condition are checked, weak ones are sistered or bolstered, and a spreader board goes beneath the feet. In a listed house the repair keeps as much original timber as it can.
Does moving a bathroom in a Bloomsbury flat need Camden building control approval?
Where new waste pipes connect to the building's stack, yes, because that is drainage work under building regulations. As a leaseholder in Camden you need the freeholder's consent and a full plans application, not a building notice. A refit with the bath, basin and toilet in their existing positions usually needs neither, although any new electrical circuit near the shower still has to be certified.
Can a bathroom be moved above a neighbour's bedroom in a Bloomsbury flat?
Check the lease before the layout. Some leases forbid putting a wet room over a neighbour's living space, and the freeholder can refuse a licence on that ground alone. With 97% of Bloomsbury homes being flats, the room below yours almost always belongs to someone else. Where consent is possible, ask for any conditions in writing, such as tanking, a leak test before the floor closes and an acoustic layer under hard tiles.
Can a new bathroom go into a listed Bloomsbury house without disturbing historic floors?
Only with listed building consent, since any change to a listed building in Camden needs it, separately from planning. The application should show the pipe routes, not only the room layout, because notching historic joists or lifting original boards is what the consent is judged on. Running wastes in a new raised floor or along a later partition keeps historic fabric intact and is easier to justify in the heritage case.
