cement-ish shower floor
 

this might be a stupid question, but from what i've read on this board
all the mortar shower pans finish with a final layer of tile. sloped
mortar membrane final mortar tile.

what if i just want the cement look? kinda loft-industrial look. no
tile.

anyone know how this is done? or is a matter of just not tiling. anyone
have a link?

much thanks
