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

Working in Longfield
We cover every part of Longfield, including DA3, DA4 and DA13, and nearby Hartley (0.7 miles) and Swanscombe (3.5 miles).
Longfield gets the same process as anywhere else: a free survey at your home and a written, itemised quote. If you are in Longfield and weighing a bath against a walk-in shower, the layout options show both with their prices. If your Longfield bathroom has a soil stack in an awkward corner, the design starts there, because it is the one point that is costly to move.
Most of Kent has very hard water. 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 lighting and electrical plan showing switches, fittings, shaver socket and extractor fan
- A clear view of which changes are cheap and which mean moving drainage or opening floors
- Checks on the soil stack, waste routes, joist direction, water pressure, hot water system and existing electrics
- Elevations and tile layouts on a design, supply and fit project, so the setting-out is agreed before tiling starts
Decisions to make first
Tile setting-out
Centring tiles on the window, basin or niche avoids thin slivers at the edges. Large tiles mean fewer joints but need flatter walls.
Planning for later
Timber noggins in the walls for future grab rails, a wider door or a level shower floor cost far less to build in now than to add later.
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.
