What does a new bathroom design cost in Warminster?
Design comes with the job: the survey, layout and itemised quote are free. In Warminster, a complete designed, supplied and fitted bathroom typically costs £6,600–£12,250 including VAT. The figure depends on the size of the room, whether anything moves, and the products you pick.

Working in Warminster
As well as Warminster itself (BA12), we survey in Westbury, Frome and Trowbridge.
Warminster gets the same process as anywhere else: a free survey at your home and a written, itemised quote. If your Warminster bathroom has a soil stack in an awkward corner, the design starts there, because it is the one point that is costly to move. For loft rooms and sloping ceilings in Warminster homes, the design checks head height where you stand, not just the floor area.
Supplies across most of Wiltshire 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 conversation about who uses the room, when, and what does not work about the current one
- A product list covering the suite, brassware, furniture, tiles, lighting and ventilation
- Checks on the soil stack, waste routes, joist direction, water pressure, hot water system and existing electrics
- A measured survey of the room, including ceiling heights, slopes, window and door positions and any boxing
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.
