There is a risk people will hesitate to reply as requirements outside the US may differ and I for one would not want to lead you astray. Here building authorities are very strict and unforgiving if you make a mistake. As for the layout you will find drawings with a general image search for ada+compliant+bathroom which might serve as a starting point (Import background image).

When it comes to fixtures, it depends what you are looking for. Maybe the discussion in thread 5717: Disabled adaptions can be of help, but note that wet_room.sh3d in SF 346 is not HC specified - even if it has a floor shower drain and indicates (local) dimensions for a wheel-chair. In addition you will probably need a higher toilet, special sink - and lots of railings.

Some of the Free 3D models can possibly be adjusted to HC compliance, but elsewhere online, I guess you shall find quite a few ADA compliant models. Searching 3D Warehouse for ADA compliant (or something) could be a good place to start.

Good luck.
