Bathrooms in Winchmore Hill's period houses are usually squeezed into the back addition or carved out of a small bedroom, sitting on a suspended timber floor over someone else's ceiling. GS Renovation builds them to be watertight first: tanking, falls, drainage and ventilation resolved before a single tile is chosen.
Timber floors, falls and tanking in N21
A bathroom on a suspended timber floor moves, and movement is what cracks grout and opens a seal. Before any waterproofing goes down we check the joists, stiffen where an earlier plumber notched them for a waste run, and lay a rigid deck rather than relying on original floorboards. Only then does the tanking membrane go on, taken up the walls in the wet zone and dressed into the shower tray or the formed former. For a level access wet room the falls are cut into the deck so water runs to the drain rather than towards the door.
Ventilation is the half of the job nobody photographs. In an Edwardian back addition with solid walls and a single small window, steam sits in the room, soaks into old plaster and rots the timber below the bath. We fit extraction rated for the room with a duct that reaches outside rather than terminating in a void, run it with the falls the right way so condensate drains out, and where the window is an original sash in a conservation area we look at the wall route instead. That is what keeps a new bathroom looking new after five winters.
Bathrooms above another flat in Winchmore Hill
Where the flat below is somebody else's home, a leak is not a snag, it is an insurance claim and a very bad relationship. That is why we tank fully rather than relying on tile adhesive, pressure test the pipework before boarding, and use compression or press fittings in positions that stay accessible. Any new connection to the shared soil stack, and any new pipe or vent through an elevation, needs the freeholder's consent under your lease, and we get the drawing to the managing agent early because those decisions are rarely quick.
Sound travels as easily as water in a converted N21 house. A WC flushing at midnight above a bedroom is a fair complaint, so we box and lag soil and waste runs, isolate them from joists with resilient clips, and build up the floor with an acoustic layer where the ceiling below belongs to a neighbour. All bathroom electrics, from the shower circuit to the lighting and the extractor, are notifiable under Part P and certified as part of the work, with zoned fittings appropriate to their position.
