Which towns do we cover in South Glamorgan?
Water across much of South Glamorgan is moderately hard. Taps and wastes will need an occasional descale, and chrome or brushed finishes are easier to keep clean than polished brass. Hardness varies street by street, so check the figure for your postcode with your water supplier. If you are in Cardiff and considering a freestanding bath, the survey includes a check of the floor and joists before you choose.
What the job includes
- Leak testing at the waste, overflow and taps, taking the old bath away and a final clean
- New flexible connectors or pipework, with isolation valves on the hot and cold supplies
- Levelling the bath on adjustable feet or a cradle, with timber battens fixed to the walls under the rim
- Tile repairs or re-tiling around the bath, and a fixed screen where there is a shower over it
- Filling the bath before sealing, so the silicone cures with the bath at its heaviest
- Removal of the old bath, including breaking up a cast-iron bath in place where it will not come out whole
Decisions to make first
Bath panel
Acrylic panels are cheap and easy to clean; wood-effect panels match fitted furniture; a tiled panel on a frame looks built-in but needs an access hatch for the waste.
Size
Most UK baths are 1700 × 700 mm. Going longer or wider than the old bath means re-tiling and checking that the new one fits up the stairs.
Taps or filler
Deck taps on the rim are the simplest swap. Wall-mounted taps or a bath filler look cleaner but mean opening the wall, and an overflow filler hides the spout altogether.
Acrylic or steel
Acrylic is warm to the touch, light and the usual choice; thicker, reinforced acrylic flexes less. Enamelled steel is rigid and hard-wearing but feels colder, and needs sound-deadening pads to stop it drumming.
Rules that apply in Wales
Replacing a bath in an existing bathroom does not need planning permission, and a straight swap is not normally building regulations work. New taps or a filler must meet the water fittings rules where you live, including backflow protection. If the new bath is much heavier than the old one, such as a cast-iron or stone resin freestanding bath, the floor needs checking, and strengthening joists is structural work that may need building control approval.
Wales sets its own building regulations, including a Part P with a wider list of notifiable electrical work than England. A like-for-like bath swap is not usually building regulations work, but speak to building control before strengthening a floor for a heavy bath.
