Dries 2 loads overnight in our large bathroom. Super cheap as we're on E7. 

Advising anyone to use a portable electrical appliance in a bathroom, especially one with loads a wet/ damp laundry is quite simply bad advice.

This is how we use it. 

What's the safety risk versus a kitchen, if the bathroom is otherwise dry and not being used?

Different regulations apply for kitchens and bathrooms.
But the most obvious answer is most bathrooms do not have a electric socket, I know I have never seen one.

I've sent lots of bathrooms with electrical sockets. But you don't need a socket in the room.

You've not actually answered Emma's question, though.

Quite a common thread on DIY board is about high humidity levels in bathrooms and how to mitigate it.

Most people when they come out the bath or shower are dripping wet, luckily I do not see much of that in our kitchen.

I think we can agree it is unwise to be trailing any powered extension leads into the bathroom while bathing.

Not only while bathing but at anytime,must say I am quite surprised that on a energy board in the year 2025 that there are so many posters who think it is acceptable.

And some of them must have strong bladders if they can guarantee not to use the bathroom for the purpose it is intended for overnight.

Some of us have more than one "throne".

That could prove the old adage right, "toffs are careless"

If I were you I would go with a compressor type, the Meaco ones are great. I have the older version of this one, it draws about 140w in laundry mode which is maximum extraction power.

Thanks! Do you find that 12Litres is sufficeint?

The tank capacity you need will depend on how long you want to run it for unattended,  I run mine for 7 hours overnight and 12 litres would not be sufficient.

Wow, a 12L dehumidifier tank filing up overnight? What's the capacity of your tank? 

I'm guessing 12L

What's more surprising is that amount of moisture being pulled out of the air of a house.

At 20C, air saturated with moisture would contain 17 mL water per cubic metre. Pulling it down to 50% RH would condense half of that moisture. Meaning it would be turning over a minimum volume of 1,400 m^3. This would in practice be a smaller volume where there is damp in the fabric of the home. Insensible water loss (breathing and perspiration) could contribute about 800 mL per day per occupant. The rest would come from activities and external sources. It seems quite a lot.

For me, drying a full load of laundry in a small room about half fills my 12L tank. For normal usage mine will run for about 48-72 h between empties if holding RH at 50%. But this is for a relatively small home with single occupant.

Again is device rated 12l or  tank actually 12l - its important not to confuse the 2.

They are not one and tge same.

And the 12l extraction only applies at 30C and 80% RH - you are virtually never going to see that in most uk homes.

For instance the Maeco 10 and 12l models only have 2.5l tanks.

That's still a lot of moisture - more than a large 2l bottle of pop when full.

My 10l model similar tank size, and that will last several 2 hour timed sessions focused around heavy cottons (towels, sheets etc) on  laundry days.

Not a toff, just someone in a flat with two bathrooms.

Mine is 10L rated, and in the specs it had "Tank volume: 2.6 Gallons" which would be around 12L. But I should have checked the actual tank as it clearly isn't that big. In the printed manual that came with it it says 2.6 L rather than 2.6 Gallons. So looks like there was a unit mismatch somewhere along the line.

So... 48-72 h of normal use to collect 2.6 L in my case.

I've got a 30 litre pro breeze compressor one that I use mostly for drying clothes in the winter. It's fairly noisy and power hungry at 500 Wh but will dry 3 x 9KG loads in our bathroom in about 5 hours filling it's 4 litre tank.

If you read through the replies again I think you will get the gist of why it is inadvisable and in one off my replies I mentioned that having laundry in the bathroom and the dehumidifier out in the hallway with the door open would be a more sensible approach than the one you advocate.

@Reed_Richards are you saying that you're dehumidifying a space (I'm assuming not a home) where you are pulling more than 12 litres of water from the air in a seven hour period?

That's huge.

From the Meaco table that Scot_39 shared, you'd need to be running nine of their "12 litre" dehumidifiers in a 30C, 60%RH environment to achieve that.

Are you trying to dehumidify an indoor heated swimming pool?

I see absolutely no issue running an extension lead to the bathroom for the dehumidifier personally.  Provided you aren't in the bath or shower at the same time whats the issue?

The UK is pretty much alone with not allowing sockers in (average sized) bathrooms.

If you shut the door you focus the dehumidifier effects, I don't usually want to dehumidfy the entire flat, plus it's in the way in the hallway outside the bathroom.

it seems that you're the only one with an issue, but you still can't explain how a dehumidifier in a dry bathroom that is not being used for showers/bathing or going to the loo, is more dangerous than drying washing in any other room.

We've got a Meaco Arete 25l unit with a 4.8 litre tank which can suck a lot of water out of the air when we first start using in November. It easily fills the tank around three times in two days until the humidity settles down and then its around half a tank a week.
It sits in the hallway of our 140m2 bungalow and keeps the average R/H down to around 60% at a temp of 20 degrees (i've got temp/humidity monitors in most of the rooms). I dont bother monitoring the consumption
