What size pipe should a shower drain be?

2-inch
Keep in mind that shower drain assemblies are generally made to fit a 2-inch drainpipe, not the 1 1/2-inch pipe usually found on tubs. A 2-inch pipe is the recommended size because showers have a low threshold for flooding, and a 2-inch pipe helps the water drain faster than does a 1 1/2-inch pipe.

What size pipe runs to a toilet?
