What does a new bathroom design cost in Dartford?
Design comes with the job: the survey, layout and itemised quote are free. In Dartford, a complete designed, supplied and fitted bathroom typically costs £7,300–£13,500 including VAT. Labour costs in South East England put local prices at about 12% above the UK guide figure. The figure depends on the size of the room, whether anything moves, and the products you pick.

Working in Dartford
We cover every part of Dartford, including DA1, and nearby Bexley (2.8 miles) and Swanley (3.8 miles).
In Dartford, as anywhere, the age of the house decides a lot: pipe sizes, floor construction and where the soil stack runs. A design survey in Dartford covers drainage, supplies, electrics and ventilation, so nothing on the drawing is guesswork. If your Dartford bathroom has a soil stack in an awkward corner, the design starts there, because it is the one point that is costly to move.
Supplies across most of Kent 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
- A measured survey of the room, including ceiling heights, slopes, window and door positions and any boxing
- A product list covering the suite, brassware, furniture, tiles, lighting and ventilation
- A written, itemised quote, with the price fixed in writing once the layout and products are agreed
- Checks on the soil stack, waste routes, joist direction, water pressure, hot water system and existing electrics
Decisions to make first
Storage
Fitted furniture, a vanity with a tall cupboard, or recessed niches and a mirror cabinet. Recessed storage costs no floor space but needs a stud wall or deep boxing to sit in.
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.
