This explains what a symbol represents on a drawing. Conventions vary between firms and standards, and a drawing's own legend takes precedence.

How to read it

The Army's print-reading manual names shower stalls among the fixtures shown on plans by pictorial or block symbols, and has separate symbols for a single shower head and gang shower heads. The Navy's Utilitiesman course lists tubs, showers, tub-and-shower combinations and gang showers, a large room with no partitions.

Also searched as: shower pan, shower stall.

Look-alikes

A bathtub is longer, with the drain at one end. A floor drain on its own is a small circle with FD.
