What does a new bathroom design cost in St Helens?
Design comes with the job: the survey, layout and itemised quote are free. In St Helens, a complete designed, supplied and fitted bathroom typically costs £6,100–£11,250 including VAT. Prices in North West England run at about 6% below 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 St Helens
As well as St Helens itself (WA9, WA10, WA11 and 1 more postcode districts), we survey in Prescot, Ashton in Makerfield and Huyton.
St Helens has a wide mix of house ages, so the survey is where we spot old lead pipework, weak joists or a tight soil stack. If you are in St Helens and weighing a bath against a walk-in shower, the layout options show both with their prices. For loft rooms and sloping ceilings in St Helens homes, the design checks head height where you stand, not just the floor area.
Most of Merseyside is supplied with soft water. That leaves you free to choose matt black, brushed brass or clear glass without worrying much about 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
- Layout options drawn to scale, showing the bath or shower, WC, basin, storage and towel rail
- A conversation about who uses the room, when, and what does not work about the current one
- Checks on the soil stack, waste routes, joist direction, water pressure, hot water system and existing electrics
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.
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.
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.
