What does a new bathroom design cost in Hounslow?
Design comes with the job: the survey, layout and itemised quote are free. In Hounslow, 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.
Survey and layout

Detailed design
- Elevations and tile layouts

Working in Hounslow
As well as Hounslow itself (TW3, TW4, TW5 and 5 more postcode districts), we survey in Isleworth, Heston and Feltham.
In Hounslow, many bathrooms are in flats or converted houses, so we check lease consents, access and the floor below before we price. We measure Hounslow bathrooms on site before drawing anything, so layouts are based on your walls rather than a standard plan. A design survey in Hounslow covers drainage, supplies, electrics and ventilation, so nothing on the drawing is guesswork.
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
- A written, itemised quote, with the price fixed in writing once the layout and products are agreed
- 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 lighting and electrical plan showing switches, fittings, shaver socket and extractor fan
Decisions to make first
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.
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.
