What does a new bathroom design cost in Harpenden?
Design comes with the job: the survey, layout and itemised quote are free. In Harpenden, a complete designed, supplied and fitted bathroom typically costs £6,900–£12,750 including VAT. Prices in East of England run at about 6% 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 Harpenden
We work right across Harpenden — AL5 — and in neighbouring St Albans and Luton.
Homes in and around Harpenden vary, so we look at the floor, the walls and the water system before we price anything. Whether you are in Harpenden or elsewhere in Hertfordshire, layout options come with an itemised written quote. If you are in Harpenden and weighing a bath against a walk-in shower, the layout options show both with their prices.
Most of Hertfordshire 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
- A conversation about who uses the room, when, and what does not work about the current one
- Elevations and tile layouts on a design, supply and fit project, so the setting-out is agreed before tiling starts
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.
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.
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.
