Which towns do we cover in Dyfed?
Supplies across most of Dyfed are soft. 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. If you are in Llanelli and weighing a bath against a walk-in shower, the layout options show both with their prices.
What the job includes
- A lighting and electrical plan showing switches, fittings, shaver socket and extractor fan
- 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 written, itemised quote, with the price fixed in writing once the layout and products are agreed
- 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
Decisions to make first
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.
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.
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 Wales
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.
Wales has its own Parts F, H and P. Extract rates are similar to England, but more electrical work is notifiable, so the design should allow for a registered electrician to notify it.
