What does a new bathroom design cost in Hayes?
Design comes with the job: the survey, layout and itemised quote are free. In Hayes, a complete designed, supplied and fitted bathroom typically costs £8,100–£15,000 including VAT. We adjust the national guide for London, where prices are typically about 25% above the UK average. The figure depends on the size of the room, whether anything moves, and the products you pick.

Working in Hayes
In Hayes we cover UB3, UB4 and UB11; we also cover Southall, 2.3 miles away, and Heston.
London homes in Hayes often mean stairs, permits and neighbours below; we plan the logistics as carefully as the bathroom. If you are in Hayes and weighing a bath against a walk-in shower, the layout options show both with their prices. If your Hayes 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 Greater London is 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
- Checks on the soil stack, waste routes, joist direction, water pressure, hot water system and existing electrics
- Layout options drawn to scale, showing the bath or shower, WC, basin, storage and towel rail
- Elevations and tile layouts on a design, supply and fit project, so the setting-out is agreed before tiling starts
- A clear view of which changes are cheap and which mean moving drainage or opening floors
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.
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.
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.
