Plumbing and fixture installation covers the pipework and hardware that make a bathroom function: running or rerouting supply and waste pipes, fitting baths, showers, toilets, basins and taps, connecting extractor fans and underfloor heating manifolds, and making sure everything is sealed, pressure-tested and compliant with Water Regulations. It's usually the stage that sits between first-fix carpentry and tiling, so timing and coordination with other trades matter as much as the plumbing itself.
What to look for before you hire
Check that the plumber holds Gas Safe registration if they're also touching a combi boiler or gas connections, and confirm they're registered with a competent person scheme (or will notify Building Control) for any work that falls under Part P or Part G rules. Ask whether quotes include waste removal, making good after chasing walls, and a written guarantee on workmanship separate from the fixture manufacturer's warranty. Bristol's older terraces and conversions often have lead or outdated waste stacks, so a fitter who's dealt with period plumbing locally is worth more than one working from a generic price list.
