Bathroom Renovation Southgate

GS Renovation fits bathrooms, en-suites and wet rooms across Southgate's 1930s semis, post-war houses and flats, where the original bathroom is often small and awkwardly placed. We handle the waterproofing, drainage, tiling and heating so your new bathroom is built to last, not just made to look good.

In Southgate, 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 Southgate: 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 Southgate 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 Southgate

A bathroom fails from the inside out, so we start with proper tanking. Before a single tile goes on, we waterproof the walls and floor of the wet zones, which matters in a Southgate semi where the bathroom often sits above a habitable room. For walk-in showers and full wet rooms we form the falls, lay the tanking membrane and test it, so water reaches the drain and nowhere else.

Drainage and ventilation are the parts nobody sees but everybody notices when they go wrong. In these interwar houses the soil pipe and vent runs are often original, so we upgrade them to cope with a modern shower and extract moist air properly to prevent damp and mould. Underfloor heating, warmed towel rails and quality tiling then turn a cold 1930s bathroom into a genuinely comfortable room.

Housing in Southgate

On the valuation list Southgate counts about 7,360 homes, 48% flats and 53% houses; 18% predate 1919, 42% are interwar and 41% post-war. A semi in Southgate can vent its bathroom through the flank, and 28% of homes here are semi-detached.

Joining the bathroom and separate toilet in a Southgate semi

In a Southgate home built between 1919 and 1939, as 42% were, the bath and basin often sit in one small room and the toilet in another beside it. Taking out the dividing partition gives one usable bathroom, but check it first. The partition can be a thin brick or stud wall carrying ceiling joists or the bearers of the cold water tank above, and the soil pipe that served the toilet fixes where the new one can go. The two rooms may also have floors at slightly different levels and two small windows, one of which may be better blocked or reglazed.

Losing the separate toilet has a cost of its own. A family with one bathroom and no second toilet will queue every morning, so the sensible order in a Southgate semi is often a downstairs cloakroom first, under the stair or in the old larder, and the upstairs merge second. A cloakroom needs its own soil connection and mechanical extraction if it has no window, and a space under the stair must still leave enough headroom to use it. Plan both rooms together so the drainage for each is laid once.

En-suites and small bathrooms in N14

The bedrooms in an N14 interwar semi are usually generous enough to carve out an en-suite, particularly the main bedroom over the bay. We plan the layout carefully so the new drainage can reach the existing stack without ugly boxing, and choose space-saving fittings that give a usable shower, basin and WC without crowding the bedroom. Careful setting out is what makes a small en-suite feel considered rather than squeezed.

The family bathroom in these houses is often a tight, single space, so clever planning earns its keep. A walk-in shower in place of a bath, a wall-hung WC and basin, and a well-placed mirror can change how big the room feels. Notifiable electrical work, from the shower to the lighting and heating, is certified by a registered electrician under Part P, so your Southgate bathroom is safe as well as smart.
