Working in Melksham
In Melksham we cover SN12; we also cover Trowbridge, 4.8 miles away, and Chippenham.
Melksham gets the same process as anywhere else: a free survey at your home and a written, itemised quote. We measure Melksham bathrooms on site before drawing anything, so layouts are based on your walls rather than a standard plan. For loft rooms and sloping ceilings in Melksham 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
- Layout options drawn to scale, showing the bath or shower, WC, basin, storage and towel rail
- A lighting and electrical plan showing switches, fittings, shaver socket and extractor fan
- A measured survey of the room, including ceiling heights, slopes, window and door positions and any boxing
- Elevations and tile layouts on a design, supply and fit project, so the setting-out is agreed before tiling starts
Decisions to make first
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.
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.
