Electrical for Steam Shower Install
I've got a 7.5 KW Amerec unit that is 130 feet from the panel to the unit. I wanted to check some things: is 6/3 thhn correct? Is the recommended 30 amp breaker correct, and should it be a GFCI? Amerec says it doesn't need to be GFCI, but not sure that is correct.

My steam generator is not on a GFCI breaker. My steam generator is located in a different room than the bathroom which might make a difference.
Does your steam generator have an automatic drain? If not make sure you install it so it is easy and convenient to manually drain it. I'm on a well and have a lot of minerals in my water so frequent draining is important.

Welcome to the forums.
If you are running conduit...... then you use THHN wire.
If you are running cable then it's NM-b w/ground.
Your 7.5kw heater requires #8 wiring and a 2P40 breaker or equivalent.
That would mean if your heater is 240v only..... you would use 8-2 NM-b w/gr as neutral is not required. If your heater is 120/240v then you will need 8-3 NM-b w/gr.
Since your heater draws just over 30A..... a 30A breaker is not sufficient. You would need to use the next step up based on panel manufacturer and breaker size availability.
