Replacing a toilet seat on a back to wall toilet

[amatos]

Hi,

One of my toilet seats broke and I'm trying to replace it. I thought it would be an easy thing to do but this toilet is a back to wall toilet, like in this picture (not exactly the same but very close):

The only thing it got are two holes on top where the screws from the old seat were attached, i.e. it doesn't have the standard fixings with wing nuts to attach a regular toilet seat.

Would I need to get a seat from the pan manufacturer? Would standard seats work?

Thanks.

You need a 'top-fixing' seat or kit

Thanks, I wasn't aware.
