Bathroom Renovation Holloway

GS Renovation refits bathrooms throughout Holloway, from compact bathrooms in N7's flats and converted Victorian houses to en-suites carved out of period bedrooms. We handle the full job, tanking and waterproofing, drainage, ventilation, tiling, underfloor heating and the fittings, delivering wet rooms and walk-in showers that work in the tighter spaces these homes have.

In Holloway, 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 Holloway: we carry the tanking, plumbing and tiling as one contract, with the electrics certified by a registered electrician.

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.

Wet rooms and en-suites in Holloway

Space is usually the challenge in a Holloway bathroom, whether it sits in a house's rear closet wing or in a room borrowed from a bedroom. We plan layouts that make the most of every inch, using walk-in showers, wall-hung basins and concealed cisterns to keep the floor clear. In a period terrace, fitting an en-suite often means routing new drainage and a soil connection carefully through existing joists, which we detail before any tiling begins.

Proper waterproofing is what makes a bathroom last, especially a wet room. We tank the walls and floor with a fully bonded system before tiling, so water cannot track into the timber structure of an older terrace. Falls are set correctly to the drain, ventilation is designed to clear moisture from rooms that often have no opening window, and any electrical work for showers, heating and lighting is certified by a registered electrician under Part P.

Housing in Holloway

On the valuation list Holloway counts about 10,640 homes, 90% flats and 10% houses; 40% predate 1919, 6% are interwar and 50% post-war. Where most homes are flats, a bathroom in a flat in Holloway sits over a neighbour's ceiling, so tanking comes first.

What sits under a new Holloway bathroom floor

In Holloway 90% of homes are flats, so a bathroom refit sits over somebody's ceiling or beside their bedroom wall. In a converted house from before 1919 the floor is timber, and a shower tray or wet room former can be dropped between joists only where the engineer confirms the joists can be notched or packed. In a post-war block the floor can be concrete, so a level access shower needs the floor built up, and the step at the door is either accepted or designed around. The survey records which floor you have before the layout is agreed.

Moving the bathroom to a different room brings in the building regulations for drainage and ventilation, and in a flat with a shared entrance a building notice cannot be used in Islington, so the change goes in as full plans. The lease usually requires the freeholder's consent as well, and a freeholder has most reason to question a bathroom moved over a neighbour's bedroom. We pressure test new pipework before the floor is closed and record the ceiling below with its owner, so any later stain in a Holloway flat can be traced to its real source.

Space-saving bathrooms for N7 terraces

In many N7 period houses the bathroom sits in the rear closet wing, a narrow room off the half-landing with little room to work. We use every trick to make these spaces feel larger, from large-format tiles and a wall-hung suite to a walk-in shower behind a single glass screen. Underfloor heating frees up wall space that a radiator would take, and recessed niches in the tiled wall give storage without eating into the footprint.

Where a Holloway family needs a second bathroom, we often find space for an en-suite or a downstairs shower room by borrowing from an oversized bedroom or an underused hallway. We handle the drainage, the waterproofing, the tiling and the fittings as one continuous job, so the room is watertight and finished properly. The result is a bathroom that suits modern life while fitting neatly into the constraints of a Victorian or Edwardian terrace.

• Pressure and leak testing before any tiling starts
• Floor strengthening before large-format tiles or stone
• Full plumbing, drainage and waterproofing (tanking)
