In Sunbury-on-Thames, as anywhere, the age of the house decides a lot: pipe sizes, floor construction and where the soil stack runs. A design survey in Sunbury-on-Thames covers drainage, supplies, electrics and ventilation, so nothing on the drawing is guesswork. Whether you are in Sunbury-on-Thames or elsewhere in Surrey, layout options come with an itemised written quote.
Supplies across most of Surrey 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 lighting and electrical plan showing switches, fittings, shaver socket and extractor fan
- Elevations and tile layouts on a design, supply and fit project, so the setting-out is agreed before tiling starts
- A measured survey of the room, including ceiling heights, slopes, window and door positions and any boxing
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.
