What does a new bathroom design cost in Southampton?
Design comes with the job: the survey, layout and itemised quote are free. In Southampton, 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 Southampton
As well as Southampton itself (SO14, SO15, SO16 and 3 more postcode districts), we survey in Hythe, Totton and Hedge End.
In a city the size of Southampton, parking and access for a skip are worth sorting before the start date — we will ask at the survey. We measure Southampton bathrooms on site before drawing anything, so layouts are based on your walls rather than a standard plan. If your Southampton 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 Hampshire is 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 lighting and electrical plan showing switches, fittings, shaver socket and extractor fan
- A product list covering the suite, brassware, furniture, tiles, lighting and ventilation
- Layout options drawn to scale, showing the bath or shower, WC, basin, storage and towel rail
- A clear view of which changes are cheap and which mean moving drainage or opening floors
Decisions to make first
Keep or change the layout
Keeping the WC and shower where they are saves on plumbing. The WC is the costly one to move, because it is tied to the soil stack.
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.
