Luxury bathroom and wet-room refurbishment in Bow. Trusted, professional, 30+ years' hands-on experience.
GS Renovation renovates bathrooms and en-suites across Bow, working with the tight, characterful spaces found in the E3 area's Victorian and Edwardian terraces. With more than 30 years of experience, we deliver fully waterproofed wet rooms, walk-in showers and family bathrooms, handling the drainage, ventilation, tiling and heating as one properly sequenced job.

Getting the waterproofing right matters most in an old Bow terrace, where floors are timber and rooms sit above 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 full wet rooms we build the falls carefully so water drains where it should, then bond the tiling onto a substrate that will not flex and crack the grout over time.
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.
Bathrooms in Bow terraces are frequently squeezed into the rear closet wing or carved from a former box room, 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 instead of protruding shelving. The aim is a bathroom that feels generous even on the compact footprint these houses 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 solid-wall period house. Where soil connections are awkward we plan the runs discreetly so nothing boxes in the room unnecessarily. Notifiable electrical work near water is certified under the Building Regulations, giving you a bathroom that is both practical and properly signed off for an E3 home.
A bathroom lives or dies on what happens beneath the tiles, and that is where our 30 years show. Bow homeowners get proper tanking, upgraded drainage and real ventilation, not just a smart-looking surface. One team handles the plumbing, waterproofing, tiling, heating and electrics, all sequenced correctly and certified where required, so your E3 bathroom stays dry and sound for the long term.

FAQ
Scope first, condition second, access third. A bathroom renovation project in a Bow home is costed on what the structure is actually doing, which is why an engineer is appointed where the design requires one. Getting a lorry or a skip near the E3 property in Bow changes the labour line more than people expect. The Tower Hamlets Council fee is shown separately, and the E3 survey establishes all three before GS Renovation commits to a Bow figure. As a rough guide, bathroom renovation in London ranges from roughly £6,000 to £20,000 or more (indicative London ranges, MyBuilder and Checkatrade, 2026). Your figure depends on the size, specification and condition of the property, which is why we survey before quoting.
Structure first, then services, then finishes, with the Tower Hamlets Council inspections fixed between them. That sequence is what stops trades undoing each other on a bathroom renovation job at an E3 address, and it is written into the programme GS Renovation issues with the quotation. Your Bow project is updated against it weekly. Nothing is concealed anywhere in Tower Hamlets before it has been inspected. Ask GS Renovation on 07472 424 226 for the written E3 programme before you commit.
We build to a design, we do not write one. Where bathroom renovation in an E3 home involves beams, openings or altered load paths, GS Renovation appoints an independent structural engineer and coordinates them through Tower Hamlets Council sign-off. That separation protects the Bow homeowner. Propping and sequencing on site are then ours to get right. Ring 07472 424 226 and we will explain the Tower Hamlets sequence. The engineer is appointed and paid through the Tower Hamlets contract.
The electrical element is, under Part P, and it must be certified. Wet systems tie into the heating and engage Part L. We install and test underfloor heating before tiling at your E3 property, and the certification goes through Tower Hamlets Council with the rest of the work.
Only where planning designations apply, and internal work is often unaffected. Bathroom renovation in a listed Bow building needs listed building consent as well as Tower Hamlets Council approval, and unauthorised work is a criminal offence. GS Renovation leads that application for an E3 property. We confirm the designation before anyone spends money on drawings in Tower Hamlets. Ask on 07472 424 226 which consents bathroom renovation actually needs at an E3 property in Bow in the first place.
Yes. The key is thorough tanking and a rigid, well-supported substrate so the timber floor cannot flex and crack the tiling. We form the correct falls to the drain, upgrade the waste and ventilation, and can add underfloor heating. Done properly, a wet room works well upstairs in an E3 terrace and protects the rooms below from any water ingress.
Yes, from any part of Bow and the E3 area, and from the surrounding Tower Hamlets too. GS Renovation quotes bathroom renovation free of charge with no obligation, whether the property is at E3 or over towards Bethnal Green.
