I’ve got eleven pull cord switches sitting in a coffee can in my garage right now. Not installed anywhere. Not waiting for a project. Just sitting there, ceramic and bakelite and one weirdly heavy chrome one, because every time I’ve ripped out a bathroom over the last however many years I’ve pulled the old switch, thought “that’s still good,” and dropped it in the can instead of the skip. My wife asked me last month what the plan was for eleven light switches and I genuinely didn’t have an answer. The honest answer is there is no plan.
I just can’t throw out a piece of hardware that still works.
That coffee can is basically a physical record of every version of this argument I’ve had on a job site, because the bathroom light switch question comes up constantly, and it’s one of those things where everybody’s got a strong opinion and about half the people are working from outdated information. Can you have a light switch inside a bathroom at all? Short answer, yes, in most places, if it’s the right kind of switch installed the right way. Longer answer, it depends what’s already in the wall, what the room’s laid out like, and honestly what you’re used to, because I’ve fitted plenty of homeowners who insisted on outside switches purely because that’s what they grew up with, no other reason.
I’m not an electrician and I want to say that up front, clearly, because this whole topic sits right on the line between joinery and something I’m not licensed to touch. I’ll build the wall, box out for the switch, run the conduit route if it’s needed, but the actual connection, the testing, whether the circuit’s protected properly, that’s a qualified electrician’s job every single time, no exceptions, and anyone telling you otherwise on a forum somewhere is not someone whose bathroom I’d want to be standing in. What I can tell you is what I’ve seen work, what I’ve seen fail, and which option I’d actually pick if it was my own bathroom, which it has been, twice.

Pull Cord Switches
This is the classic inside option and it’s the one most people over forty grew up with, ceiling mounted, insulated cord hanging down, you give it a tug and the light comes on. The logic’s sound. Keep the actual switch mechanism up high, away from the sink, away from anyone’s wet hands reaching for a wall plate at eye level. I’ve fitted these into ceiling roses that were older than me, and taken a few down where the joist blocking behind them had gone soft from decades of steam, which tells you something about longevity in that environment even when the switch itself is fine.
The cord’s the weak point, not the switch. I’ve replaced more snapped pull cords than actual failed mechanisms, because people yank them wrong, or a towel gets caught in one, or a kid uses it as a rope swing, don’t ask. My dad always said the ceiling rose install matters more than the switch you’re hanging off it, and he’s not wrong, if that rose isn’t screwed into something solid you’ll feel it wobble every time you pull the cord, and a wobbly fixture two feet above a bathtub is not a feeling I want in my house.
The upside is real though. No wall plate at hand height means no wet fingers on live contacts, no kids flicking it on and off forty times a night, and honestly there’s a satisfying click to a good cord switch that a flat plastic rocker just doesn’t have. If you’re keeping an older bathroom’s character, or you’ve got a low ceiling situation where the cord’s actually reachable without a step stool, this is still a legitimate choice, not just a relic.

Switches Outside the Door
This is what most modern new builds default to, and if I’m honest it’s usually my first recommendation, purely because it removes the whole conversation. No wet zone, no rating to worry about, no cord to snap, just a standard switch on the hallway wall like every other room in the house. Simpler wiring run in a lot of cases too, since you’re not threading cable through a wall that’s also dealing with a shower feed or a vent fan circuit.
The complaint I hear most, and it’s a fair one, is the fumble in the dark. Someone gets up at 2am, doesn’t know the house yet, hits the wrong switch, and now the hallway light’s blazing and everyone’s awake. I fitted a rental property a while back where the previous owner had put the bathroom switch and the hall closet switch about four inches apart at the exact same height, no logic to which was which, and the tenant complained for a full year before anyone fixed the labeling. That’s not the switch’s fault, that’s a layout mistake, but it’s the kind of thing that gives outside switches a bad reputation they don’t fully deserve.
The other real issue is kids and guests leaving the door open because the light’s outside and closing the door means fumbling for a switch they can’t see yet. Small thing. Adds up over a family of five. But from a pure “what’s actually going to last and cause the fewest headaches” standpoint, an outside switch on a normal circuit, properly labeled, is about as low maintenance as this gets, and that counts for something.

IP-Rated Switches Inside the Bathroom
If you actually want a wall switch inside the room, at a normal height, this is the category that makes it legitimate rather than a fire hazard, and it’s the bit I want to be really clear about, because it’s changed a lot in the last decade or two and plenty of homeowners are still working off what their parents had. Modern bathroom rated switches carry an IP rating, usually something like IP44 or higher depending on how close it sits to a water source, and that number refers to how sealed the unit is against moisture and dust, not a suggestion, an actual tested standard.

I took one of these apart once out of curiosity on a switch I was replacing anyway, not live obviously, fully isolated first, and the gasket around the plate was a proper molded silicone seal, not a bit of foam stuck on as an afterthought. That’s the difference between a switch that’s rated for a bathroom and one that just looks similar on a shelf at the hardware store. Cheap knockoffs exist here too, same as everywhere, and the tell is usually a plate that doesn’t sit flush or a gasket that’s clearly been trimmed down from a bigger sheet rather than molded to size.
Here’s the bit I won’t budge on. Where that switch goes, how far from the sink or the shower zone, what circuit protection sits behind it, that’s all governed by electrical code that varies depending on where you live, and it’s genuinely not something to guess at or copy off a video online. Get a licensed electrician to spec it and install it. I’ll happily build the wall around it and make sure the box sits square and solid, but the electrical decision itself isn’t mine to make and it shouldn’t be yours either.

Two-Way Switching
This is the option I actually recommend most when someone’s doing a full renovation and the walls are already open, because it sidesteps the whole either-or debate. You get a switch outside for the normal flick on your way past, and a second switch inside, properly rated, for when you’re already in there and don’t want to walk back out into a dark hallway. Wired as a two-way circuit, either one turns the light on or off regardless of the other’s position.
The catch is cost and access. This needs two runs of cable and a slightly more involved wiring job than a single switch either location, so it’s a much easier add during a gut renovation than a retrofit into finished walls, unless you’ve got an electrician willing to fish cable through existing cavities, which some will and some flatly won’t depending on how the house is built. I’ve opened up plaster and lath walls where fishing a second cable run meant basically redoing a section of wall anyway, so the timing matters as much as the idea.
When it’s done right though, it’s the setup that gets zero complaints. Nobody’s fumbling for the switch on the wrong wall, nobody’s leaving a bathroom light on all night because they couldn’t find the switch on the way out, and if the interior one fails or needs replacing eventually the outside one’s still there as a backup while you sort it. It’s more work up front. I still think it’s worth it if the walls are already open and you’re not trying to save every last dollar on the electrical line item.

Sensor and Smart Switches
The newer entrant to this whole argument, and one I was skeptical of for longer than I probably should have been, is the motion sensor or touchless switch, usually mounted at a normal wall height but designed so you never actually make contact with it, wave your hand near it or just walk in and it triggers. For a bathroom specifically that’s a genuinely sensible pitch. No wet fingers touching anything electrical at all, sensor or standard wall height, doesn’t matter.
I fitted one of these for a client with young kids who kept leaving the bathroom light on for hours, and it solved that problem completely, timer cuts the light after the room’s empty for a set period.
The install itself still needs the same rated backing box and the same electrician sign off as any other bathroom switch, sensor or not, so it’s not a shortcut around the wiring conversation, just a different front end on it.
Where I’d push back a little is reliability over time. I’ve seen a couple of these develop false triggers a few years in, lights flicking on at 3am for no obvious reason, which the client found funny for about a week and then not funny at all. Nothing that couldn’t be fixed by swapping the sensor unit, but it’s a moving part that a plain mechanical switch just doesn’t have, and moving parts are always the first thing I check when something’s acting up on a job.

Final Thoughts
So which one would I actually pick. If I’m building from scratch and the walls are open, two way switching, no contest, it’s more work but it’s the version that makes every future 2am bathroom trip slightly less annoying. If I’m working with an existing layout and don’t want to touch the walls, outside switch every time, it’s the lowest maintenance option and it sidesteps the whole rated hardware conversation entirely.
If someone’s set on a switch inside the room itself, for looks or for habit, that’s fine, plenty of good options exist, but it has to be properly rated hardware installed by someone qualified to make that call, not a standard switch moved somewhere it was never meant to live. That’s the one place in this whole debate I won’t soften, because it’s the one place a shortcut actually matters. Everything else here is preference. That part isn’t.
