Which towns do we cover in South Glamorgan?
Supplies across most of South Glamorgan are moderately hard. A quick wipe of the glass and an easy-clean coating are worth having on a new shower in Cardiff. Hardness varies street by street, so check the figure for your postcode with your water supplier. For Cardiff houses with only one bath, we talk through whether to keep it before you decide.
What the job includes
- A thermostatic shower valve, with the pipework moved for the new head position
- Silicone, a full-flow test and a tidy finish where the new tiling meets the old
- A low-profile tray, or a former and tanking for a level-access floor
- Removal of the bath, panel and taps, and disposal of the waste
- Grab rails and a fold-down seat if you want them
- Boarding, tanking and re-tiling of the shower walls
Decisions to make first
How much to re-tile
Re-tile just the shower walls, or take the chance to re-tile the whole room so new and old tiles never have to match.
Mixer or electric shower
A thermostatic mixer draws on your hot-water system. An electric shower heats cold mains water as it flows and needs its own circuit.
Your only bath?
If this is the only bath in the house, think about whether you, or a future buyer, will want one before you commit.
Safety extras
A fold-down seat, grab rails and a slip-resistant tray cost little at the time of fitting and are much harder to add later.
Rules that apply in Wales
Converting a bath to a shower does not need planning permission. The shower area is a special location under BS 7671, with 30 mA RCD protection on every circuit and at least IPX4 fittings in zone 1 above the tray up to 2.25 m. A shower pump can only be used on a gravity system with a cold tank, never on the mains. Where the conversion adapts the home for a disabled person, the work can be zero-rated for VAT under HMRC VAT Notice 701/7.
In Wales, the Welsh Part P covers more electrical work than in England, and a new electric shower circuit must be notified. Disabled Facilities Grants in Wales can be up to £36,000, approved by the council before work begins.
