Wall hung WC dimentions

[DIY_Disasters]

Hi,

I'm looking to install a wall hung WC in a bathroom refit. Does anyone know if the frames and WC's are universal? I can see on some frame designs that the centres from the waste pipe to the flush pipe are 135mm, and the odd WC diagram also shows the same measurement, but some WC diagrams don't show the centres measurement at all. I presume the hanging bolts should typically be the same distance apart on WC's too, so that they match all frames that are manufactured?

Thanks.

My experience is limited to buying a Jacuzzi (brand) (off floor) pan, to attach to a Oki concealed frame. The fitting bolt distances were seemingly "universal".

The height of the waste pipe was however adjustable. From memory there was threaded bolt with a collar (that holds the female waste pipe connector) that could be adjusted up and down.

My frame is fixed in terms of soil and flush pipe but has two separate pairs of threaded holes for the mounting bolts, it's a different make to the WC but I'm confident they'll work together.

Thanks both. Well I will order the frame and WC Im after and go from there.
