Bathroom Renovation Dartford

GS Renovation fits bathrooms in Dartford, including the work behind the tiles: the drainage, the first fix, the waterproofing and the making good. A bathroom put in a new position, or added to a house that is going to be let, raises questions a straight replacement does not. Abdelaaziz Saaid brings over 30 years of hands-on experience, and quotations are free and carry no obligation.

For Dartford, on London-derived ranges a full bathroom refit typically costs £6,000 to £20,000 or more; Kent work generally runs below that. GS Renovation Ltd, a building contractor based in Potters Bar, does the work in Dartford: 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 Dartford 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.

Adding bathrooms for a Dartford HMO now needs planning permission

The permitted development right has been withdrawn north of the A2. Dartford Borough Council resolved at full Council on 8 December 2025 to bring into force immediately an Article 4 direction for houses in multiple occupation covering that area. The direction was confirmed by full Council on 23 February 2026. Adding en suites to a house there in order to let it as an HMO now sits behind a planning application.

South of the A2 the date is later. That direction was confirmed on 23 February 2026 and takes effect on 10 December 2026. From then, planning permission is required to convert a house into a house in multiple occupation for up to six occupants. If that is the plan for the property, the consent question comes before the bathroom specification.

Housing in Dartford

Count the homes in Dartford and you get about 26,860: 60% built since 1945, 24% between the wars and 15% before 1919, with flats at 27% and houses at 73%. 37% of homes here are terraced; a terrace bathroom in Dartford vents front, back or up, never into a party wall.

Drainage in Dartford is treated as a flood risk question

The council's own evidence base treats it that way. The Dartford Strategic Flood Risk Assessment identifies surface water, groundwater and sewer flooding as potential sources of flood risk in the borough, alongside fluvial and tidal flooding. A new bathroom adds fixtures to a drainage system that was sized for fewer of them, so where it connects matters as much as what it connects to.

We look at the run before agreeing the layout. Falls, vent positions, the route to the existing stack and whether a pump is needed all decide where a shower or a WC can sensibly go. Moving a soil connection is the expensive part of a bathroom. It is better priced honestly at the survey than discovered under the floor once the room is stripped.

Owner occupied and rented bathrooms are specified differently

The difference is in what the room has to survive. The Dartford Plan to 2037 records 2021 census data on tenure in the borough. Owner occupied and mortgaged properties make up approximately two thirds of the housing stock, with private rented at 18.1 per cent and social rented at 13.8 per cent. What lasts in a family bathroom is not the same as what lasts in one used by a succession of tenants.

Waterproofing is where we would not economise either way. Tanking behind a shower, correct falls to the waste and a properly sealed junction between tray and wall are what stop a leak reaching the ceiling below. Tiles and taps are visible and easy to change later. The layer behind them is neither, so it gets specified first and it stays specified.

• Tanking membranes and waterproof boards behind tiles
• Notifiable bathroom electrics certified by a registered electrician under Part P
