Tap back nut removal

[Serval]

I want to replace the taps in a bathroom sink but im having trouble finding a tap wrench of the correct size:
1 - to fit the back nut.
2 - to get access under the sink behind the tails

The back nut measures 37 AF and the tap tails are the fixed copper type which look fixed to the tap body....

side note:
I recently replaced my downstairs cloak room which had the same sink and tap arrangement which i kept and chopped
up to experiment on with out having to worry about destroying anything.

Heres a couple of pics showing what the old one looks like.




out of interest how would you even get the back nut off from the tails with out having to bend them? ( the new tap has flexi tails but im just curios as to how you would do it if say you just wanted to temporarily remove the existing tap)

The taps that i need to remove have got very limited clearance under the sink with no way to get an adjustable spanner or set of jaws around.
ive done a search for 37mm basin wrenches and can seem to find anything of that size either... the all seem to be 15/22
Any suggestions on how to remove this without chopping up my sink!?

Or, hammer and chisel to get it moving

Thanks rpm,

Ive looked into the 2nd option but ended up returning it as it didn't fit the back nut

Opps, my bad, think there is a larger version.

You wouldn't get the back nut off without bending the tails and removing the fittings.
This will fit practically all and has a thinner jaw than some.

Steel handle with hexagonal end and removable tommy bar. Fits 15mm and 22mm (1/2" and 3/4") nuts.

If the whole thing is very tight see if by holding the back nut with one hand and rotate the tap body instead this often works Centralheatking
