Hello, I just purchased a Morgan Monaco tub. I am wanting to put it on the back porch which is 21 ft X 12 ft wide. The porch is covered, concrete flatwork with Mexican Satillo tile squares. My questions are. How far from the walls do you want it? Will the tile and flatwork be adequate for the weight of the tub? What about loose water coming over the side? Do I need to raise the tub or build a deck around it??? How far from the spa does the breaker box need to be??? Thanks in advance. Al
