Tap removal

That's the tool to use if you don't want to re-do the pipework (though you'll probably need a new fibre washer for the tap connector) but it's a PITA to use - I usually cut off the pipe tails and use a box spanner. Monument do one specifically for bath and basin taps. Then you can refit the taps with flexible tails.

I might disconnect at the isolating valve - then I don't need to concern myself with the fibre washer.

Do I assume you have no concerns about the chunkiness of the tool?

=============================== This one is easier to use:

You'll need to disconnect at the tap connector to remove the tap - or do you just want to loosen the backnut without removing the tap?

Can't say for sure without seeing the clearance around the taps underneath your basin - only you can tell that

I have a similar one, but I used this one last month for a similar job.

Basin wrenches are much too bulky for most tap backnuts.

Backnut box spanner available from plumbers merchants is the tool you need.

You may still need the adjustable wrench to dis/connect the tap connector though.

I've tried several and prefer this one

Backnut box spanner is the tool to use for basin taps ,no swearing or cursing and the tap will stay where you put it ,there are cheap ones out there but Monument is the best,and yes the adjustable can be to bulky for some basins

I have the Screwfix-type one too and agree wholeheartedly about the PITA bit! Hadn't heard of the Monument one - I shall look out for that. Does it fit the nut which holds the tap against the basin, rather than the pipework-tap connector?
