Which towns do we cover in Devon?
Most of Devon 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. We measure Plymouth bathrooms on site before drawing anything, so layouts are based on your walls rather than a standard plan.
What the job includes
- 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
- A conversation about who uses the room, when, and what does not work about the current one
- Layout options drawn to scale, showing the bath or shower, WC, basin, storage and towel rail
- A measured survey of the room, including ceiling heights, slopes, window and door positions and any boxing
Decisions to make first
The door
Re-hanging the door on the other side, fitting a sliding pocket door or moving the opening can free up a whole wall in a small room.
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.
Where the shower goes
A shower on an outside wall is easier to ventilate; one under a sloping ceiling needs full head height where you stand, not just at the high side.
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
Changing the layout inside an existing bathroom does not need planning permission. The design does have to respect the electrical zones around the bath and shower under BS 7671, the water fittings rules for new WCs and taps, including a maximum 6-litre flush, and adequate extract ventilation. Listed buildings need listed building consent for alterations affecting their character, including new soil or vent pipes through walls, and in a flat the lease often requires freeholder consent for moving the WC or adding a new vent.
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.
