Question: what is the average size of a 3/4 bathroom?
Answer: Average 3/4 bathroom is about 6' x 6', but larger sizes might be a good option for convenience. Full size bathroom with separate 36 x 36 inches shower, standard 5 feet wall to wall bathtub, 60”W x 21”D x 36”H vanity and regular toilet has to be at least 50 ft² big.
