Cowboy, can I just say that you won’t be the first one to hop in the bath tub because they miss diving? It may need to be a big tub with all of that gear but you can do it! haha. With Greg being an instructor, he’s tested gear out in our bath tub many times. (actually, he probably wasn’t testing it, just using that as an excuse to put it on.. ) Anyways, go for it! ;O)
