What does a new bathroom design cost in Northolt?
Design comes with the job: the survey, layout and itemised quote are free. In Northolt, 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 Northolt
We work right across Northolt — HA2, UB5 and UB6 — and in neighbouring Greenford and Harrow.
London homes in Northolt often mean stairs, permits and neighbours below; we plan the logistics as carefully as the bathroom. A design survey in Northolt covers drainage, supplies, electrics and ventilation, so nothing on the drawing is guesswork. We measure Northolt bathrooms on site before drawing anything, so layouts are based on your walls rather than a standard plan.
Most of Greater London 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
- Elevations and tile layouts on a design, supply and fit project, so the setting-out is agreed before tiling starts
- A product list covering the suite, brassware, furniture, tiles, lighting and ventilation
- A lighting and electrical plan showing switches, fittings, shaver socket and extractor fan
- Checks on the soil stack, waste routes, joist direction, water pressure, hot water system and existing electrics
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.
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.
