Bathroom Renovation Bow

GS Renovation renovates bathrooms and en-suites across Bow, working with the tight spaces of E3's post-war flats and its less common Victorian and Edwardian terraces. We deliver fully waterproofed wet rooms, walk-in showers and family bathrooms, handling the drainage, ventilation, tiling and heating as one properly sequenced job.

In Bow, a full bathroom refit typically costs £6,000 to £20,000 or more (indicative London ranges, MyBuilder and Checkatrade, 2026). GS Renovation Ltd, a building contractor based in Potters Bar, does the work in Bow: we carry the tanking, plumbing and tiling as one contract, with the electrics certified by a registered electrician.

How the job runs

1. Free design visit at your Bow home and an itemised quote.
2. Strip-out, then first-fix plumbing and electrics.
3. Tanking to the wet areas, then tiling.
4. Sanitaryware and second fix, with notifiable electrics certified by a registered electrician. Typically 10 to 15 working days on site.

Waterproofing and wet rooms in Bow

Getting the waterproofing right matters most in a Bow flat above a neighbour's ceiling, or an old terrace with timber floors over living space. Before a single tile goes down we tank the walls and floor, forming a continuous waterproof layer that protects the structure below. For walk-in showers and wet rooms we build the falls so water drains where it should, then bond the tiling onto a substrate that will not flex and crack the grout.

Older E3 homes often have inherited drainage and poor ventilation that leave bathrooms damp. We upgrade waste runs, fit proper extraction to clear moisture, and where you want it lay electric underfloor heating beneath the tiles for warmth and quicker drying. The combination of sound tanking, good drainage and real ventilation is what keeps a period-house bathroom dry and mould-free, rather than the surface fixes that fail within a couple of years.

Housing in Bow

The Council Tax list puts Bow at about 15,000 homes, 81% flats against 19% houses; 23% went up before 1919, 2% between the wars and 75% after 1945. Where most homes are flats, a bathroom in a flat in Bow sits over a neighbour's ceiling, so tanking comes first.

Bathroom refits in Bow flats, old blocks and new

81% of homes in Bow are flats, so a Bow bathroom often sits over someone else's ceiling. In a block built since 2000, the bathroom may be a factory made pod or sit on a concrete slab with the waste run cast in, and the managing agent may hold the as built drainage layout. Ask for it before choosing a new layout, because it shows whether the toilet can move at all. Older converted flats more often have timber floors, where the tanking and a water test before any tile goes down matter even more, since a leak runs along the joists before it shows below.

Electrical work is one of the ways a Bow bathroom touches building control. A shower, a heated towel rail, an extractor or underfloor heating near the bath all count. Tower Hamlets Council's domestic building control charges assume a Part P registered electrician carries out that work, and a supplementary Part P charge is made in other cases. We use a registered electrician for every bathroom circuit, so the certificate comes straight from the scheme and there is no separate council inspection of the wiring.

Space-saving bathrooms in E3 homes

Bow bathrooms are often internal rooms in a flat, tied to the shared soil stack, or squeezed into a terrace's rear closet wing, so smart planning counts for more than square footage. We rework the layout to gain usable space, wall-hung basins and toilets, a slimline shower in place of a bulky bath, and recessed niches. The aim is a bathroom that feels generous even on the compact footprint these homes provide.

Adding an en-suite to a Bow bedroom is popular too, and we handle the new plumbing, drainage and ventilation needed to make it work within a flat or a solid-wall period house. Where soil connections are awkward we plan the runs discreetly so nothing boxes in the room. Notifiable electrical work near water is certified by a registered electrician under Part P, giving you a bathroom that is both practical and properly signed off for an E3 home.
