Because from your diagram and previous comment, it looks like you've got:
- shower (two lights)
- vanity overhead
- vanity on wall (two sconces, alongside, I'm assuming?).
That's a lot of single-gang switches to have at one position. There's also the question as to whether you're over-lighting the space. Ceiling AND ceiling over the vanity sink? Is a separate light over the toilet necessary? That's a lot of light for a small space and controlling them separately complicates both the wiring and how you'll use the space over time. Maybe lose the lights over the sink and the toilet and just have the ceiling? We have a ceiling light and about the only time it gets used is to clean the space. For daily use it's the vanities and shower (and toilet WC, of course).
We have our controls spread around the room, adjacent to their activity. Attached is the electrical circuit diagram (more or less, there's a few positional changes that happened during rough-in). There's a single-gang at the entrance with a keypad that has a dimmer for the ceiling. The other buttons are toggle for the vanities, the shower and the toilet WC along with a toggle to the nearby master closet.
Electrical code is particular about how close you can put a wall switch to water. That's why I asked if the shower was going to be glass. You could potentially do as I've done and have a 2-gang box on the exterior wall. That would allow reducing the number of devices over by the door.
There are things like the GrafikEye and wallbox dimmers
, that can concentrate several dimmers into a separate box (up to five, if I remember correctly). That could potentially reduce the wall clutter, somewhat, but then you introduce a level of "extra thinking" that has to go into using the space. As in, little buttons on the keypad vs separate paddle dimmers placed 'near' activities). I'm a big fan of not trying to be overly clever. For places like a home theater, a wallbox or grafikeye makes a lot of sense. But for a bath, where guests might be likely using it, you're want to avoid making it tedious to use when it ought to be simple.
Perhaps a wallbox tucked away somewhere nearby (is that a closet in the lower right?). And then a 3-gang on the wall. A paddle, keypad and paddle. The 1st paddle dimmer for the 'main lighting' for the room (could be the vanity sconces, not the ceiling). A keypad labeled for the others (ceiling, toilet, shower, all off) and then the fan. This way someone coming into the room is going to see/feel the first paddle and get lighting. Then see the keypad and be able to read for more and then find the fan. Pretty simple. The trick would being finding a place for the other load controls ceiling, toilet, vanity overhead and shower). The keypad itself can be a dimmer, but then you'd still have the rest.
I am NOT a fan of playing games like putting a bunch of single-gang dimmers hidden in a closet somewhere else. That's just ugly and presents a whole range of potential hassles later). Best to have as much wiring in the room as possible. Yours is one situation where having a wallbox gang dimmer would be worth considering. The downside to a wallbox is price and versatility, as their dimmers are built-in, not separate units. Which could present LED compatibility issues in the future. For a multi-purpose lighting scenario like this one I could see where hiding a 3-gang in a nearby location might not be a heinous offense.
Also understand that a downside to using a keypad for control is it complicates having manual dimmer adjustment. The keypads do have a raise/lower button set, and that will change the last pressed load. Which could be annoying if you want different manual dimming levels all the time. I like having the shower dimmer control near it because I don't usually like it BRIGHT AS THE SUN in there. My wife, however, does (along with it nearly hot enough to boil your skin off). So having it controlled by a keypad all the way over at the door would be annoying.
