What does a new bathroom design cost in Windsor?
Design comes with the job: the survey, layout and itemised quote are free. In Windsor, a complete designed, supplied and fitted bathroom typically costs £7,300–£13,500 including VAT. Prices in South East England run at about 12% 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 Windsor
In Windsor we cover SL4; we also cover Slough, 1.8 miles away, and Egham.
Homes in and around Windsor vary, so we look at the floor, the walls and the water system before we price anything. A design survey in Windsor covers drainage, supplies, electrics and ventilation, so nothing on the drawing is guesswork. Whether you are in Windsor or elsewhere in Berkshire, layout options come with an itemised written quote.
Supplies across most of Berkshire are 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 clear view of which changes are cheap and which mean moving drainage or opening floors
- A written, itemised quote, with the price fixed in writing once the layout and products are agreed
- 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
Decisions to make first
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.
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.
