Working in St Austell
In St Austell we cover PL25; we also cover Bodmin, 9.2 miles away, and Truro.
St Austell gets the same process as anywhere else: a free survey at your home and a written, itemised quote. Whether you are in St Austell or elsewhere in Cornwall, layout options come with an itemised written quote. If your St Austell bathroom has a soil stack in an awkward corner, the design starts there, because it is the one point that is costly to move.
Most of Cornwall 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
- Checks on the soil stack, waste routes, joist direction, water pressure, hot water system and existing electrics
- Elevations and tile layouts on a design, supply and fit project, so the setting-out is agreed before tiling starts
- A clear view of which changes are cheap and which mean moving drainage or opening floors
- A product list covering the suite, brassware, furniture, tiles, lighting and ventilation
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.
