All i could find was a version converted for TS4.

Here's a picture of it:

Hah! Found it. I had it in my game, but could not track down where I got it from. It's here (medieval bathroom). http://www.sims2graveyard.com/index...-mobel?start=80

This is not by Tarox, but it's extremely similar: http://modthesims.info/download.php?t=70326
This is by Tarox (recolors by StephSim, meshes included), but thanks to the angle of the pictures, I'm not sure if it's the one you're looking for. The washstand is not the same, but the toilet looks like it might be: http://www.medievalsims.com/forums/...hp?f=113&t=6909

Thank you esmeiolanthe and Charity!

It is no longer downloadable, not even through wayback machine.
I looked at google images to find others like this and I have found recolours but this is also unavailable, though I'd like to get those too. This is the link for the recolours of the mesh mentioned above: http://www.medievalsims.com/forums/...hp?f=113&t=6909 ( image on google images: https://i.pinimg.com/originals/0d/4...82b513ed596.jpg )
So I can not have the mesh nor the recolours. Can someone who has it upload it inside this forum thread?

^ The graveyard address changed to: https://www.simsgraveyard.com

And how am I supposed to find it there? There were the list of creators and I haven't found the original creator's name.

There's a link to it here. https://gardenofshadows.org.uk/gard...p?topic=30522.0
