In MA plumbing code, is there something called the "barrel test" for shower interior?
Hi, I have tried to Google "barrel test" and "shower", and not finding anything to back up this salesperson's statement.
I live in MA, which I think is under the UPC. I'm trying to see if my idea for a shower is valid under the code. I am a homeowner and not a plumber. I have an existing 36 inch by 32 inch space that I would like to fit a shower into (for various reasons).
I checked the code at mass.gov, and it says "900 square inches" for the shower interior.
That implies (to me) that an allowable interior is 30 inches by 30 inches (= 900 sq. inches), and allowing 2 inches for curbing, that a 32 inch by 32 inch pan would be allowable under the code.
However, I was in a bath supply shop and the salesperson told me that the minimum allowable was 36 inch by 36 inch by MA state plumbing code. She said they have the "barrel test" and try to fit a barrel into the shower.
So, I guess I have these questions:
- Has anyone heard of something called the "barrel test" with respect to the UPC or MA plumbing code? Is it the same as this salesperson said?
- Does the UPC allow a minimum shower interior of 30 inch by 30 inch, or must it be 36 in. by 36 in.?
Thanks for reading, and thanks in advance for any insight into this.
