What does a new bathroom design cost in Isleworth?
Design comes with the job: the survey, layout and itemised quote are free. In Isleworth, 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 Isleworth
As well as Isleworth itself (TW3, TW5 and TW7), we survey in Hounslow, Heston and Southall.
London homes in Isleworth often mean stairs, permits and neighbours below; we plan the logistics as carefully as the bathroom. If you are in Isleworth and weighing a bath against a walk-in shower, the layout options show both with their prices. We measure Isleworth bathrooms on site before drawing anything, so layouts are based on your walls rather than a standard plan.
Supplies across most of Greater London are 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
- Elevations and tile layouts on a design, supply and fit project, so the setting-out is agreed before tiling starts
- Layout options drawn to scale, showing the bath or shower, WC, basin, storage and towel rail
- A conversation about who uses the room, when, and what does not work about the current one
- A written, itemised quote, with the price fixed in writing once the layout and products are agreed
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.
