What does a new bathroom design cost in Chesham?
Design comes with the job: the survey, layout and itemised quote are free. In Chesham, a complete designed, supplied and fitted bathroom typically costs £7,300–£13,500 including VAT. Prices in South East England run at about 12% 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 Chesham
We work right across Chesham — HP5 — and in neighbouring Amersham on the Hill and Amersham.
Chesham gets the same process as anywhere else: a free survey at your home and a written, itemised quote. If you are in Chesham and weighing a bath against a walk-in shower, the layout options show both with their prices. If your Chesham bathroom has a soil stack in an awkward corner, the design starts there, because it is the one point that is costly to move.
Water across much of Buckinghamshire is 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 clear view of which changes are cheap and which mean moving drainage or opening floors
- A lighting and electrical plan showing switches, fittings, shaver socket and extractor fan
- A measured survey of the room, including ceiling heights, slopes, window and door positions and any boxing
- Checks on the soil stack, waste routes, joist direction, water pressure, hot water system and existing electrics
Decisions to make first
The door
Re-hanging the door on the other side, fitting a sliding pocket door or moving the opening can free up a whole wall in a small room.
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.
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.
