Which towns do we cover in West Glamorgan?
Water across much of West Glamorgan is 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 Swansea and weighing a bath against a walk-in shower, the layout options show both with their prices.
What the job includes
- 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
- 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 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
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.
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.
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.
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.
