Thanks for your reply. Yes, weight is also a concern. I calculate the tub + water + 1 person will weigh around 3500 pounds. The building is a commercial loft building, it's not being built on a loft. Joists are 3" x 12"s 16"oc. running from an adjacent, outside brick wall to a steel I beam around 16 feet away. We may put in some steel between the two outside brick walls in the corner into which this tub will be placed. However, waterproofing vis a vis the rebar and structure of the concrete in the tub are my main concerns at this point. |
