Where is the flip button? I can't find it.

I have downloaded a bathtub, but I want to use it in more than one place, and in the other place I need it to be inverted. Is there a way to do that?

Thank you.

Where is the 3D warehouse? That would be awesome. I wasn't really looking forward to have to do all that.

So, I'm using Sketchup to create my ideal house, and I want to create furniture and stuff like that, but I'm not quite sure how to do it. I would really like to create a toilet, and tub, but I'm not sure how to do rounded edges, or a bowl. Anyone have any tips?
