Mike the “Standard tub” is 5 feet long.
Now before you allow any foreign crap to come across the border I would strongly suggest that the product in question is made to ASTM specifications with ASSE approval.
You certainly don’t need the finish peeling or the opening for the over flow and tub waste to be non conforming to local codes.
Being imported do you have any idea of the quality of the finish?
These things should be made to at least be the same high quality that American companies have to deal with.
There should also be some accountability if a problem does arise (product liability)
How much lead content in the finish of this imported stuff?
Under what testing procedures was it made?
The length is not the key the materials used in manufacturer I would be more concerned about. NAIL THESE GUYS thank you. Have a great week end.
