I need information on how to get things for a hospital I'm designing.

I'm new to LibreCad design, and I need the following:

wc (water closet), hwb (hand water basin), bath (a place where one takes a bath) and a shower reel.

I need that for the bathroom I'm designing for the hospital and anything else. Thank you.

You should search online for that type of content. There are sites with lots of CAD blocks for that type of thing.
