I need to install a clothes washing machine in the bathroom and I have a problem to solve.
The drain hose of the washing machine is 25 mm in diameter on the exterior, made from a soft rubber material – see image A, while the drain is 32 mm in diameter internally made from hard plastic – see image B.
How do I connect them? Is there some piece that goes in between I can buy? Do I need to cut the head of the drain hose and replace it with something else?
I'm going to assume that there's not a trap inside the wall, but if I'm wrong please correct me.
You're going to want to build a standpipe. Start by installing a P-trap into that pipe in the wall. It's hard to tell from the picture what type of pipe it is, but you'll want to use something compatible to make the connection between pipe and trap.
From the other end of the P-trap, you'll want a 2" diameter pipe going straight up 18"-42" long.
You'll then put the washer drain into the top of the standpipe, as described in the manufacturer's installation instructions.
When you're done, it should look something like this.
Replace this hose with a single long hose.
Remove the hose that came with the unit and measure the size of the fitting it was attached to. Go to a good hardware or plumbing shop and buy a single length of heavy duty reinforced rubber hose and a hose clamp to fit. This is the only correct way to do it IMO.

32mm equals 1.25" USA. Standard 1.25" drain pieces can be obtained at any hardware,Home Depot, Walmart, etc. You could buy another 1-1/4" desanco fitting x 1-1/2" abs or pvc piping. Use the 2 desanco pieces with their washers and jamb nuts back to back and convert to a stand pipe with the 1-1/2" abs or pvc and dump the washing machine drain hose into the stand pipe.
