GFCI protection of bathroom


I have a bathroom circuit I need to GFCI protect.

Power comes from the panel to a receptacle just outside the bathroom. From the receptacle to two switch boxes - one which controls a light outside the bathroom door - and one to a switch box in the bathroom. From the switch box in the bathroom to a light, a fan, and a receptacle beside the sink.

The switch in the bathroom is within 1 m of the shower stall so needs class A GFCI protection and the receptacle beside the sink needs GFCI protection.

Two questions:

1. Is it allowed to protect the whole circuit by replacing the first receptacle with a GFCI receptacle and connecting lines an loads appropriately?
2. This first receptacle supplied two other enclosures. Can I bring power in, tie it into the line screws, and pigtail the two loads before connecting to the load screws?

The box is 18 cu.

A $20 GFCI receptacle is much more attractive than an $85 GFCI breaker

The switch, outside the shower does not need protection, unless it switches a fan in the shower. The receptacle does need to be GFCI

Local rules vary, I would assume no ... but you know what they say about assuming, check with local building division.

By him using 1 m of the shower makes me think he may be in Canada, so US rules would not apply.

Yepp. I'm in Canada. According to the CEC, all switches within 1 m of a shower stall must be GFCI class A protected.

From ESA FAQ:

Question
Is a separate circuit required to supply a receptacle in a bathroom?
Answer

The code does not require a separate circuit for bathroom receptacles. Bathroom receptacles can be supplied by a general purpose circuit that supplies other general purpose receptacle and lighting outlets. Multiple bath and washrooms are permitted to be supplied by the same circuit.
