Wall vent in ensuite

Hi.

We had an ordinary wall vent in an ensuite and no condensation/mould issues.

The room was renovated and the bathroom company tiled over the vent for a better finish.

There is a window in the bathroom which we open regularly but that has not been enough to clear condensation after a shower and this has resulted in mould.

We are currently using a dehumidifier which is grand but we've decided to knock through the tile and put our air vent back where it was.

Question, how big does the hole need to be to be effective? The outside vent is still there. We know exactly where to put the hole in the tile but just not sure how big it needs to be.

Thank you.
 
Thank you. The problem is the whole room is tiled so the condensation is ceiling to floor all over. I'd need a ladder!

Yes, but only wipe down the shower area where water gathered from the shower itself. Also not a squeegee as such but a window wiper that the window cleaners use, and they have a long handle for extra height. I actually use a Karcher as it also sucks the water up and you can empty it in the sink. It also keeps your tiles cleaner for longer.
But I have digressed from your original question. Have you old pictures of the bathroom which might help you pinpont the old position ?

Pretty stupid thing to do.

I open the window, leave the door open and use the yoke in the attached link on the window, the mirror over the wash-hand basin,
and the shower door. My house was a new build and the rule of thumb apparently is not to have a vent in bathrooms with a window. En-suite and downstairs jacks have extractor fans.

Mine is older in Karcher yellow. Handy yoke
 
A vent is typically used to allow fresh air into a room, you should also have an extractor fan to remove moist air.

When showering etc you need to consider 1 - how you are expelling moist air and 2 - how you are allowing fresh air in. One doesn't work without the other.

If you have an extractor fan, it will work fine if you open a window (even a small bit) during showering and leave the bathroom door open after the shower. The fan should stay on for 15minutes or so after showering or you can get a humidity controlled fan that will turn on and off as needed.

The advice above about cleaning up condensation will help for sure but your issue won't be adddressed without fixing the ventilation strategy.
 
Thank you all. No pipe in the gap behind the tile. The house was built circa 25 years ago and I don't think there is a pipe behind any of the vent covers. Looks like vent cover inside, gap in brickwork, outside vent cover.

We have a small hole in the tile now and we can see the outside vent. We are going to make the tile hole bigger, around the 4" as mentioned above. Put on an internal vent cover and see how that works.

Seem to be working ok in other bathrooms in the house.

We appreciate all the replies.
