Roman Bathtub

What is the size of a standard tub? And not a Roman bath, important?
No standard bathroom. Tubs vary – Some are shallow, some are deep. And the tubs in various lengths from 48 "to 72" Roman baths. Would not really rules. Their tubs were nothing mason happened. If you need a bath volume of about 60 "(the majority of people) and very shallow …. probably 12" deep x 54 "long x 28" inches wide = 18,144 cubic feet or 10.5 cubic. Eureka!
