Hi folks. I just checked after drawing a component and rotating it at 45° from the red and green axes and if I flip this component along the component's red or green axis, I get the correct result. Of course the component's axis must be oriented correctly to start with. Normally, for a bathtub, the red and green shall be lying on the ground and the blue shall be pointing up. Just ideas.

When it comes time to build, you get catalogs and pick what you want. For the model of the house you might want to go with something that looks like a toilet but is low-poly (small cost in edges and faces).
