All jokes aside , if you going to do this, you know at some point when you all done , you will like to share it with your friends /guests ( like most of us would like to do) and than taking them to your bathroom would be kind of strange - I think it would be strange to me , but I know we all different - so I'm not judging
This isn't a tank I would show off, I want to try my hand at breeding clowns. Its just that space is unused and I figure if there is ever a leak it was just go down the drain. Plus I can connect my RODI right next to it also. Landlord isn't an issue. My only concern is the weight on the tub. Essentially I want to do like what Tunicata suggested. I would build a 2x4 frame on the ledge of the tub to help distribute the weight. Thats really my only concern.
What kind of tub is it? Porcelain over metal or resin....forgive me the real term is on the tip of my tongue but I cant remember the name of it....it's what corvettes are made of.
Faucets, drain anything metal around the tub ... Listen this is something you do not want to do. Or something i would never do, I love my home clean organized and no saltwater fish in my bathrooms. (i have 2 full bathrooms with tubs and 1 half bathroom).... plus my wife would prob. beat me to death :lol2:
