What does a new bathroom design cost in Welling?
Design comes with the job: the survey, layout and itemised quote are free. In Welling, a complete designed, supplied and fitted bathroom typically costs £8,100–£15,000 including VAT. Prices in London run at about 25% above the national guide, mainly because of labour rates. The figure depends on the size of the room, whether anything moves, and the products you pick.

Working in Welling
We cover every part of Welling, including DA6, DA15 and DA16, and nearby Bexley (2.3 miles) and Eltham (2.5 miles).
London homes in Welling often mean stairs, permits and neighbours below; we plan the logistics as carefully as the bathroom. We measure Welling bathrooms on site before drawing anything, so layouts are based on your walls rather than a standard plan. A design survey in Welling covers drainage, supplies, electrics and ventilation, so nothing on the drawing is guesswork.
Supplies across most of Greater London are very hard. We plan easy-clean glass, rimless toilets and finishes that do not show limescale. Hardness varies street by street, so check the figure for your postcode with your water supplier.
What the job includes
- Elevations and tile layouts on a design, supply and fit project, so the setting-out is agreed before tiling starts
- A clear view of which changes are cheap and which mean moving drainage or opening floors
- A conversation about who uses the room, when, and what does not work about the current one
- Layout options drawn to scale, showing the bath or shower, WC, basin, storage and towel rail
Decisions to make first
Keep or change the layout
Keeping the WC and shower where they are saves on plumbing. The WC is the costly one to move, because it is tied to the soil stack.
Where the shower goes
A shower on an outside wall is easier to ventilate; one under a sloping ceiling needs full head height where you stand, not just at the high side.
Rules that apply in England
In England, a new connection to the soil stack or new drainage can be building regulations work under Part H, and new circuits or alterations to circuits in the bathroom are notifiable under Part P. Where a new bathroom is formed, Approved Document F asks for extract at 15 l/s intermittent or 8 l/s continuous.
