Product review (5 stars): Cost effective laundry fixture box
Already had another one of these, but wanted a separate connector for dryer (steam).  So added a third faucet to the other one and used this one just for the drain, which I wanted to leave on the other side of a stud. It all worked out OK.  Using it that way doesn't provide a drip catcher for the valves, but it was what I needed.  This one was very inexpensive because it didn't include any plumbing, but that was just fine for what I wanted to do with it.
