Working in Trowbridge
We work right across Trowbridge — BA14 — and in neighbouring Westbury and Melksham.
Homes in and around Trowbridge vary, so we look at the floor, the walls and the water system before we price anything. If you are in Trowbridge and weighing a bath against a walk-in shower, the layout options show both with their prices. For loft rooms and sloping ceilings in Trowbridge 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 clear view of which changes are cheap and which mean moving drainage or opening floors
- A written, itemised quote, with the price fixed in writing once the layout and products are agreed
- 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.
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.
