Yeah, I used one of those small plastic raw water/pump strainers with the fairly fine screen in it. Most of the hair ends up at the shower sump
outlet "strainer", then the raw water
strainer gets the rest.
The other system I liked (to avoid a sump/float switch system, or when no room below the shower pan) is to just install a pump with the same small raw water
strainer direct to the shower pan and have a switch in the shower area. When the shower pan starts to accumulate water you turn the switch on, the exit fitting can be above waterline and very small....like 3/8 or 1/2.
