3-13-2013: Per suggestion by TheNinthWave, I updated the sink. It can be used with the 1/4 tile cheat AND an OMSP and be used on an angle. You can also use boolprop snapobjectstogrid false along with an OMSP. It will still work as it should unless: it's placed to close the the edge of the surface.
If you want the updated sink, please redownload and let the mesh replace the one in your folder. You'll have to rebuy it in game for the changes to take effect if you've already placed one somewhere. :)
The download has 15 files and they may seem un-needed/redundant. There was a method to my madness however:
*8 files are- the mesh and 7 recolors of the sink only. (Mesh has textures for the taps and the sink)
*4 files are invisible recolors for half of the faucet/taps mesh- the bottom pipes and knobs. (Since you can put this sink on a table in the middle of a room, those would look kind of funny!)
*3 files are recolors of the whole taps mesh.
As mentioned above, when you put the sink on a table in the middle of a room- the pipes and knobs that are under the sink are hanging in mid air, doing nothing more than hanging around looking pretty. But that looks silly! With the invisible recolors, you can banish those lingering bits.
The animations are a bit off if you put the sink on a counter and pretty close to perfect on table/end table height surfaces. If you put it on a narrow surface- the sink might not be usable. I tried that in game but it might have been the shelf I used since there were multiple shelves and I had deco on some of them.
No cheats are needed to place the sink, it can be found just where you'd expect it to be (Plumbing>Sinks), costs 470 Simoleons and is roughly 1800 polys.
