If you are not a plumber, and tackling a bath renovation yourself, be aware of three things:
1) This is not a shower drain.  It is a grid for a shower drain.  You need be make sure you have a shower drain that fits this item already in the spot you want it, or you need to obtain one yourself; and
2) You need to make sure this grid will fit the shower basin in your shower- and is adjustable enough so the top of the grid is even with the top of the tile.  Check with you plumber.
3) While very attractive, I'm uncomfortable about the instability of the grid (as it is just barely staying attached to the frame) when I start actually standing on it in the shower.
