Yes you can use a normal dye tub.
Btw, how do you get it to stay above the teleporter? I've tried one, it dropped under the teleporter. I tried another one raised twice and that fell under too. So i tried both together and they still fell under it
Oh, and if you're playing in the EC then don't be surprised if bits of carpet vanish now and then. Mouse over the area and they are still there...
