What does a new bathroom design cost in Horsham?
Design comes with the job: the survey, layout and itemised quote are free. In Horsham, a complete designed, supplied and fitted bathroom typically costs £7,300–£13,500 including VAT. We adjust the national guide for South East England, where prices are typically about 12% above the UK average. The figure depends on the size of the room, whether anything moves, and the products you pick.

Working in Horsham
In Horsham we cover RH12; we also cover Crawley, 7.2 miles away, and Horley.
Homes in and around Horsham vary, so we look at the floor, the walls and the water system before we price anything. For loft rooms and sloping ceilings in Horsham homes, the design checks head height where you stand, not just the floor area. If your Horsham 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 West Sussex 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
- Layout options drawn to scale, showing the bath or shower, WC, basin, storage and towel rail
- Checks on the soil stack, waste routes, joist direction, water pressure, hot water system and existing electrics
- A clear view of which changes are cheap and which mean moving drainage or opening floors
- A conversation about who uses the room, when, and what does not work about the current one
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.
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.
