Question:

Current set up on 14/3 wire + ground with two switches. One switch
controls the fan, the other switch controls the light:

Believe it is this combination:
Switch 1: Black - controls Fan
Switch 2: Red - controls Light

I would like to move fan/light above the shower but need GFCI (per
Nutone 744NT instructions). Can I somehow install two "inline" GFCI's
after the switchs but before the light and fan. One GFCI for the
black, one for the red. I would put GFCIs in a closet behind the bath
so they are accessible.

To do this I think I would have to wire the GFCIs with just one wire
(i.e. the black or red) or split the white? Otherwise what would I do
with the white (i.e. bypass it on the GFCI or split it so each GFCI
gets a white)?

To further complicate things, I would also probably put additional
recessed lights after the fan/light combo, if this matters.

(thinking of using those blank GFCI w/o the outlets)

Thanks

Anything preventing you from just changing the breaker servicing that
line to a GFCI type?

This circuit also powers a master bedroom in addition to the bath.
Would that present any issues for a GFCI. Doesn't seem like it?

I don't understand whey when the previous owners remodled a about 7
years ago why they didn't just install a GFCI breaker.

Thx

Doesn't seem like it would to me either. You might want to look into
using an "arc fault" CGCI for a bit mores safety if you decide to
change the breaker.

Should be OK.

Because they are expensive compared to a GFCI receptacle. You may be
able to install a GFCI receptacle in the switch box then feed a stack
switch off the load side of the GFCI receptacle for the light/fan.
