What size bottle trap for bathroom basin with a O/D 36mm waste pipe?

Can anyone tell me what size bottle trap for the basin in the bathroom for a 36mm O/D waste pipe? Most bottle traps seem to be listed as 32mm or 40mm?

32mm, or ask for 1 1/4” if in a plumber’s merchant.

Oh, but how would a 36mm pipe go into a 32mm bottle trap?

The trap is designed to be universal, the 32mm relates to the internal diameter of both push fit and solvent weld pipe, the outer diameter is the difference between push fit and solvent weld sizes. The trap will accept the 2mm discrepancy between the 2 pipes outside diameters.
