The pictures show this splash guard installed both ways on my kitchen sink. By that, I mean the long side on the outside of the the sink and then also on the inside of the sink. If you look at the web page, the pictures show it both ways, but I think the long side should be draped over the inside edge of the sink. I guess which ever way suit your needs the best. The 2nd picture show the long side towards the inside of the sink. It doesn't work the best for my sink. The 4th picture, show the short side toward the sink, and the longer side is on the outside of the counter. But honestly, I planning on using this splash guard along the sink in my to be completed new laundry room. That sink will not have a center divider so I think it will work better. Either way, it really helps to control the amount of water my shirt ends up absorbing. The current price is about $27. This seems a little expensive but since it helps to keep me dry, it is will worth the money. It would be nice if some type of picture showing what the "correct position" of installation should be.
