In the 2009 Commentary, it is noted as being an absolute measurement, not a min or max.The code says a transfer-type shower shall have a clear inside dimension of 36" x 36". I am assuming that is just the minimum size and you can have it larger than that but the code does not say the shower shall have a "minimum" clear inside dimension of 36" x 36". Am I wrong to assume this?
