Supplies across most of Greater London are very 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. If your Brent bathroom has a soil stack in an awkward corner, the design starts there, because it is the one point that is costly to move.
What the job includes
- A measured survey of the room, including ceiling heights, slopes, window and door positions and any boxing
- Layout options drawn to scale, showing the bath or shower, WC, basin, storage and towel rail
- Checks on the soil stack, waste routes, joist direction, water pressure, hot water system and existing electrics
- A lighting and electrical plan showing switches, fittings, shaver socket and extractor fan
- A product list covering the suite, brassware, furniture, tiles, lighting and ventilation
- Elevations and tile layouts on a design, supply and fit project, so the setting-out is agreed before tiling starts
Decisions to make first
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.
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.
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.
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.
