I want to know if anyone has made part of the garage into a fish room? and cost of it? and problems there might be? I need to get the garage door insulated enough so it does not get to hot or cold. I believe that won't be enough so i would then need to make another "room" inside the garage i am not sure how to do this. Should i get very thick tarp and make a room with that? or should i make legit walls? what do you think the average cost would be? I also would need a utility sink. Cost of that? I just need to find a way to make the room so it will not get to hot or cold. Also i would need to put about 6 more outlets in the area of the room. Cost of that? I am very serious about attempting this so please help me out here and give me some input thx everyone!!!!!!
