What does a new bathroom design cost in Weymouth?
Design comes with the job: the survey, layout and itemised quote are free. In Weymouth, 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 Weymouth
In Weymouth we cover DT3 and DT4; we also cover Dorchester, 7.2 miles away, and Poole.
In Weymouth, as anywhere, the age of the house decides a lot: pipe sizes, floor construction and where the soil stack runs. For loft rooms and sloping ceilings in Weymouth homes, the design checks head height where you stand, not just the floor area. A design survey in Weymouth covers drainage, supplies, electrics and ventilation, so nothing on the drawing is guesswork.
Supplies across most of Dorset 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 measured survey of the room, including ceiling heights, slopes, window and door positions and any boxing
- 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
Storage
Fitted furniture, a vanity with a tall cupboard, or recessed niches and a mirror cabinet. Recessed storage costs no floor space but needs a stud wall or deep boxing to sit in.
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.
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.
