Which towns do we cover in South Glamorgan?
Most of South Glamorgan has moderately hard water. 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. Where a Cardiff shower room doubles as the guest bathroom, we plan storage so it stays clear of clutter.
What the job includes
- Tanking to the shower area, then wall and floor tiling
- A survey of water pressure and flow, the hot-water system and the floor where the tray or former will sit
- Extractor fan, lighting and towel rail wired by a qualified electrician, tested and certified
- A thermostatic shower valve, exposed or concealed, with a fixed head, a handset or both
- Removal of the old bath and suite, waste removal, testing and handover
- A low-profile tray or a tiled level floor, with the waste positioned for a good fall
Decisions to make first
Drain
A centre waste in a tray is the norm. A linear drain along one wall lets a tiled floor fall one way, so large tiles can run through.
Tray size
A 1200 by 800 mm or 1400 by 900 mm tray with a single panel makes a comfortable walk-in. Go as long as the room allows; length does more than width to keep spray inside.
Valve and heads
A bar valve is simple and easy to service. A concealed valve with a ceiling head looks cleaner but needs good flow to perform.
Glass
8 mm toughened glass is the usual standard for a walk-in panel. An easy-clean coating helps a great deal in hard-water areas.
Rules that apply in Wales
Turning a bathroom into a shower room does not need planning permission. The electrics must meet BS 7671: 30 mA RCD protection on every circuit, at least IPX4 fittings in zone 1 above the tray up to 2.25 m, or IPX5 where water jets are used, and no ordinary sockets within 3 m of zone 1. A shower pump can only be used on a gravity system with a cold tank, never connected directly to the mains.
Wales has its own Part P and Part F. More electrical work is notifiable there than in England, and the extract rates are similar.
