Waterproofing and wet rooms in Tower Hamlets
Getting a bathroom right in Tower Hamlets starts below the surface. We tank and waterproof properly before a single tile goes down, which matters especially in E14 and Wapping flats where a leak reaches the neighbour below and the block's management is quickly involved. For walk-in showers and full wet rooms we form the falls, tank the whole area and bond the tiling to a surface that will stay watertight for years.
Drainage and ventilation get the same care. In a converted flat we work with the existing soil stack and limited routes for waste, and we fit proper extraction to keep moisture from causing damp. Underfloor heating, thermostatic showers and quality tiling all follow once the waterproofing is sound, so the finished bathroom looks sharp and performs reliably day after day.
Housing in Tower Hamlets
Roughly 149,830 dwellings sit on the valuation list for Tower Hamlets. 10% are houses and 90% flats, and by age 12% predate 1919, 4% are interwar and 83% post-war. A bathroom in a flat in Tower Hamlets sits over a neighbour's ceiling, so tanking comes first, which matters here because most homes are flats.
Bathroom wiring and letting rules in Tower Hamlets
Electrical work is one of the ways a bathroom refit in Tower Hamlets touches building control. A shower circuit, a heated towel rail, an extractor fan or underfloor heating near the bath or shower all count, and Tower Hamlets building control prices its domestic work on the basis that a registered Part P electrician carries it out. Using anyone else adds a supplementary Part P charge. We use a registered electrician for bathroom circuits, so the certificate comes from the scheme and no separate electrical inspection is needed.
Adding bathrooms so a house can be let room by room is a planning matter here. Tower Hamlets Council's Article 4 direction removing the right to convert residential dwellings (C3) to small HMOs (C4) came into force on 1 January 2021. Letting a Tower Hamlets house to three to six unrelated sharers is that change of use, however many en suites it has, so it now needs planning permission. Settle the use before the bathrooms are designed, because shared living also brings its own fire separation and ventilation rules that decide where the new rooms can go.
En-suites and clever layouts across E1 to E14
Space is tight in many Tower Hamlets homes, so smart planning earns its keep. In a Bethnal Green or Bow terrace we fit an en-suite into a former box room or a slice of a larger bedroom, and design family bathrooms that make the most of an awkward footprint with wall-hung units, recessed niches and a walk-in shower instead of a bulky enclosure. Period homes reward a layout planned around the existing plumbing runs.
In leasehold conversions and riverside apartments the constraints are different but just as real. Structural change is limited, sound insulation between flats matters, and the freeholder's licence to alter and managing agent may need to approve the works. We plan within those rules, keep bathroom electrics and any notifiable work compliant with building regulations, and deliver a clean, well-finished space that suits the home.

FAQ
Frequently Asked Questions about Bathroom Renovation Tower Hamlets
How accurate is a bathroom renovation quote for a Tower Hamlets house?
The accuracy of a bathroom renovation quote in Tower Hamlets depends on the information behind it. A phone figure will move; one written after GS Renovation has checked the E1 property usually does not, because soil stack distance decides where a Tower Hamlets WC can go, and that is only visible on site. Any Tower Hamlets Council building control fee is shown separately, and the range to compare against is £6,000 to £20,000 or more (indicative).
Can you fit a wet room in my Canary Wharf apartment?
Yes. Wet rooms work well in E14 apartments provided the waterproofing is done properly, which is essential when a leak would reach the flat below. We fully tank the area, form the falls and check the drainage and ventilation against the building's constraints. In a leasehold flat we also confirm the freeholder's licence to alter and any managing-agent rules before starting, and keep notifiable electrics compliant.
How long does a bathroom renovation in a Tower Hamlets flat take?
Plan for 10 to 15 working days on site. Part of that is waiting: tanking cures before tiling, and adhesive sets before grouting. In a block, the tanking is water tested before any tile goes on, since a leak lands in the flat below, and noisy stripping out is kept to the hours the managing agent allows. With one bathroom, arrange a shower elsewhere for the duration.
Can I move my Tower Hamlets bathroom further from the soil stack?
Only a short way in most flats. The stack serves every flat in the vertical line, and the toilet pipe must fall steadily into it; a concrete floor offers no joist void to hide that pipe in, so a raised floor across the room becomes the only option. The lease usually requires the freeholder's written consent to move a bathroom. A macerator is possible but is best kept as a last resort.
Can a renovation improve shower pressure in my Tower Hamlets flat?
Often, once the supply is understood. A combi is limited by the mains flow reaching your flat, which can vary by floor in a tall block. An unvented cylinder can give a stronger shower but needs a cupboard and a discharge route outside. Where hot water comes from a communal system, the shower has to suit what it supplies. Measure the flow before choosing the shower.
What electrical rules apply in a Tower Hamlets bathroom?
In Tower Hamlets, as elsewhere, new circuits and wiring near the bath or shower are notifiable Part P work a registered electrician certifies. Fittings are chosen for the zone they sit in: lights and fans close to the shower need a water protection rating suited to that position, and switches go outside the room or use a pull cord. Mirror demisters and heated towel rails are wired as fused connections.
Does a new bathroom in a listed Tower Hamlets house need listed building consent?
Usually, if it alters the building. Altering a listed building in Tower Hamlets, internally or externally, needs an application for listed building consent. A new bathroom tends to need a new soil pipe route, an extract vent through an outside wall and floorboards lifted for pipework, and each of those can affect historic fabric. Plan the pipe and vent routes early and include them in the application, since they are the part most likely to be questioned.
What is different about refitting a bathroom in a Tower Hamlets flat built since 2000?
It may not be a room in the usual sense. Of the homes in Tower Hamlets, 45% date from 2000 or later, and some blocks of that age use factory made bathroom pods, where the walls and floor arrive as a single unit. Cutting into a pod can affect its waterproofing and the fire and acoustic line around it. Ask the managing agent whether the flat has a pod before planning a new layout.
Where can a new soil pipe or extract vent go on a Tower Hamlets house in a conservation area?
Check the area's guidance first. Tower Hamlets has 58 conservation areas, each covered by its own appraisal and management guidance. In a conservation area a new soil or vent pipe on a wall of a house fronting the road is not permitted development, so it needs planning permission. Route new drainage and extraction to the rear or internally where the layout allows, and check it against the guidelines.
