A straightforward tap replacement, where you’re swapping an old tap for a new one of a similar type, usually takes 20–40 minutes for a professional plumber, assuming the shut-off valve is working and there’s no unusual corrosion. They’ll turn off the water, loosen the old fittings, clean the threads or surface, fit the new tap with proper sealing material, and then test for leaks.
It can stretch longer if the old tap is rusted solid, the access is awkward (like under a cramped sink), or the valve that shuts water off is stuck and needs attention first. For a homeowner trying it for the first time, expect it to take more than an hour, including watching tutorials, getting the right tools and cleaning up.
The good news is that it’s one of the simpler plumbing jobs. If your house has decent plumbing and valves, replacing a dripping, ugly tap with a fresh one is a small job with a big daily impact. Just make sure you buy the correct size and type before you start.
