Hello,

Some context to consider : The basement was already roughed-in (plumbing and electrical) for including a bedroom and bathroom. The bathroom is 96" x 64" and can't be made bigger. It is limited on all 4 sides : the exterior wall, the plumbing stack, access to the bedroom door, the bedroom wall. The bedroom door can't be relocated as the bedroom is in the basement corner between the utility room and bathroom. The house was built in 1993.

Question A : When ontario electrical code (or canadian code?) requires an outlet near the sink, can I use a combination switch/plug ? Or do I need a regular duplex receptacle ?
Question B : when you count 12 lights and/or outlets per circuit (for the general whole basement) the duplex receptacle counts as 1 outlet ?


I was planning the following 3-gang configuration located between the toilet and pedestal sink :
- fan control that came with the fan (automatic on humidity sensor and a manual switch that activate pre-set timer)
- 3-way dimmer to control the ceiling lights (other switch is outside the bathroom, it has to be next to the door but far from the shower)
- "Leviton Decora 15A Switch and GFCI Receptacle" with the GFCI receptacle for the shaver/iron/etc and the GFCI switch will control the vanity lights.

As for circuits, what I gather is that there will be a 20-amp circuit for
- the ceiling 3-way dimmable lights (the other ceiling light switch is outside the door because the door is directly next to the shower)
- the fan (it is in the shower because the middle of the bathroom already have the heat register. moving the register would require a HVAC contractor and permit. having the fan right next to the register might pull in the air from the register.)

And a second circuit of 20 amp for
- the single GFCI vanity plug (I read because of the hair iron/hair dryer it needs to be 20-amp instead of 15amp ?)
- the outlets on the wall next to the toilet (no idea why the previous owner placed a non-GFCI outlet there, but i'll keep the oulet location to plug in the bidet seat on a GFCI receptacle.)
- the vanity light switch (it could have gone with either circuit but is simpler to keep with the plug as it is part of a combo)

Also, I gather that the light switch (dimmer and combo) must be GFCI if located between 0.5m and 1m from the shower. Which is the case here; I have it at 27" (0.68m) from the shower. In order to have it at 40" away it would need to be located on top of the toilet which would look odd while still conform with the standard of having it within 36" of the sink.

In the current set-up, there is an outlet next to the toilet. An outlet between the toilet and sink. A vanity light with a pull-chain switch. A ceiling light with a switch outside the bathroom.

I know this is a lot of text for only two questions. But i was thinking with more details someone might spot something that I missed.

Oh I forgot question C : How do you GFCI protect the bathroom fan ? Do I install a GFCI blank face ? If so, is there code on where to situate it (anywhere inside bathroom, near electrical panel, outside face of the bathroom wall) ?

a - yes. needs to be GFCI though.
b - yes. duplex counts as one.

As for circuits, what I gather is that there will be a 20-amp circuit for
- the ceiling 3-way dimmable lights (
Can't do that. Lighting must be on 15 amp circuits.

And a second circuit of 20 amp for
- the single GFCI vanity plug
20 amp circuit will require the receptacle be a T slot 20 amp type.

c - Connect the switch power from the LOAD side of the GFCI receptacle. It's not a light so I think it is OK on the 20 amp circuit. If the fan has a light then it must be on 15 amp circuit. You could use a GFCI breaker.

You can get many of your answers from the ESASAFE FAQ site.

Thank you. I read* what i understood as it was 15 amp if lights alone and 20 amp if you have lights and vent fan on same circuit. If you add a heater, then heater fan on 20 amp, and a seperate lights circuits.

i did more research on how many amps you need for a vent and i think i just need a 15 amp. the fan instruction doesn't specify 15 or 20 amp circuit, but does list the unit as taking 25 watts. So, i could have the lights and fan on the same circuit at 15 amp ?

While I can put almost all of my basement lights on one circuit, I don't want to have 3 circuits come in the same 3-gang box.

I tried to edit my post but it looks like the edit button is time-limited.

*from thespruce (based on NEC which is not for Ontario Canada) :
General lighting/fan circuit required: Each bathroom should have a circuit for lighting and an exhaust fan. According to the Code, this circuit may be a 15-amp circuit if it serves just lighting, but it should be a 20-amp circuit if it is also serving a vent fan. If the vent fan includes a heat lamp, then a separate 20-amp circuit, in addition to the lighting circuit, should power the vent-fan/ heat lamp combination.

As I can't edit. Here is my revised circuits following the 15-amp max on lights.

As for circuits, what I gather is that there will be a GFCI 15-amp circuit for
- the ceiling 3-way dimmable lights (the other ceiling light switch is outside the door because the door is directly next to the shower)
- the fan (it is in the shower because the middle of the bathroom already have the heat register. moving the register would require a HVAC contractor and permit. having the fan right next to the register might pull in the air from the register.)


And a second circuit of 15 amp for
- the single GFCI vanity plug (I read because of the hair iron/hair dryer it needs to be 20-amp instead of 15amp ? *edit:does not need to be 20 amp if using a single device at a time)
- the outlets on the wall next to the toilet (no idea why the previous owner placed a non-GFCI outlet there, but i'll keep the oulet location to plug in the bidet seat on a GFCI receptacle.)
- the vanity light switch half of the leviton combo.

good thing i didn't buy the 15A switch and receptacle combo from home depot yet. I thought we could use 15amp outlet on a 20A but as you say in Canada the outlet and circuit must match. I'll have to hunt for a store that sells the leviton 20amp GFCI and switch combo (https://www.leviton.com/en/products/5636-w)


*it is not GFCI but i can make the whole circuit GFCI at the breaker or in this case of outlets i can have a the duplex GFCI feed the vanity outlet. Is it code in Canada to have a GFCI feed protection for a non-GFCI outlet downstream ?
