Bathroom Renovation Havering

GS Renovation fits bathrooms and en-suites across Havering, working in the post-war houses and 1930s semis that fill RM1 to RM14. Across Romford and Upminster, drawing on our founder's 30+ years on the tools, we handle the full job, from stripping out and tanking through drainage, ventilation, tiling and underfloor heating to a finished, watertight bathroom or wet room.

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

How the job runs

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.

Wet rooms and en-suites in Havering

The 1930s semis of Havering were built with a single family bathroom, often over the hallway or above the kitchen, so adding an en-suite or a second bathroom is a frequent request. In these homes we carve space from a large main bedroom or the landing, and we design compact, well-planned layouts that fit without feeling cramped. Every wet area is properly tanked and waterproofed before tiling, so moisture never reaches the timber floors of an interwar house.

Walk-in showers and full wet rooms are popular in RM11 and RM12 homes, whether for a sleek modern finish or to make a bathroom easier to use over time. A wet room needs the floor tanked, the gradient formed correctly to the drain, and reliable extraction to manage humidity, all of which we build in from the start. We upgrade the drainage and soil connections where the original interwar pipework is undersized or in the wrong place.

Housing in Havering

Around 108,680 homes make up Havering on the valuation list; 26% are flats and 74% houses, and 5% date from before 1919, 36% from between the wars and 59% from after 1945. Semi-detached houses make up 29% of homes here, and a semi in Havering can vent its bathroom through the flank.

En-suites for shared houses and newer Havering homes

Adding en-suites so that a Havering house can be let room by room can be a planning question before it is a plumbing one. Havering's two Article 4 Directions on houses in multiple occupation were made on 3 November 2015 and came into force on 13 July 2016. Notice 1 covers the Brooklands, Romford Town, Heaton and Gooshays wards, and outside those wards a second direction means turning a flat, terraced house or semi-detached house into a house in multiple occupation needs planning permission. Settle the planning position before the bathrooms are designed, because the use, the fire separation and the number of rooms are decided together.

13% of Havering homes were built in 2000 or later, and a new bathroom in one of those meets a different floor. Upstairs joists in newer houses may be engineered timber joists with a thin web, which can be drilled only in the zones the manufacturer allows and never notched. Others are metal web joists, whose open webs let a pipe pass through but whose timber top and bottom must not be cut. A waste pipe for a new shower or basin therefore follows the routes the joist allows, or drops into a boxed route below. Find the joist type and direction before choosing where the shower tray goes, because that decides whether the waste can reach the stack at all in this Havering house.

Waterproofing and comfort across Havering

Getting a bathroom right in an older Havering home is as much about what sits behind the tiles as the tiles themselves. We tank showers and wet areas thoroughly, seal around trays and junctions, and detail the waterproofing so leaks never start. Ventilation matters just as much in these interwar houses, so we fit effective extraction to clear steam and protect the plaster and paintwork, keeping the room fresh and free of damp.

Underfloor heating under tiled or stone floors takes the chill off a north-facing Havering bathroom and frees up wall space by removing the radiator. We can pair it with heated towel rails, thermostatic showers and quality brassware to suit your budget. New circuits and changes around the bath or shower are notifiable under Building Regulations, so the wiring, extraction and any electric underfloor heating are installed correctly and the electrics certified under Part P by a registered electrician. From a family bathroom in RM1 to an en-suite in RM14, we finish the whole room to a high standard.
