What the job includes
- A clear view of which changes are cheap and which mean moving drainage or opening floors
- Layout options drawn to scale, showing the bath or shower, WC, basin, storage and towel rail
- Elevations and tile layouts on a design, supply and fit project, so the setting-out is agreed before tiling starts
- A written, itemised quote, with the price fixed in writing once the layout and products are agreed
- A conversation about who uses the room, when, and what does not work about the current one
- A lighting and electrical plan showing switches, fittings, shaver socket and extractor fan
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.
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.
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.
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.
