Bathroom extractor
Discussion
Hi all,
I have a small extractor in my bathroom which doesn't work that brilliantly.
It is mounted in the old standard vent position so on the outside wall is a brick grill, an oblong block full of cutout squares.
When I run the extractor I seem to get more cavitation than extraction and the steam which comes out of it seems to fall out as apposed to push out, like my kitchen extractor.
Are there many options for a new grill on the outer wall?
I know there are better extractors which would go above the shower but I don't want to have to cut holes and then re-tile the wall with the hole in.
Dave!

I have two and looks fine 
as they are just grills rather than sticking out like wall fans. One is a grill over the external air brick and second is a grill in ceiling.
It means I do not need to leave a gap under the bathroom door to get air in , so minimal noise leakage. Plus no need to have window open.
But your mind seems set on the wall ones, so is it a case of it never having worked or just recently? If latter then have you removed the fan and checked that nothing is clogged e.g. dust buildup.
If former then try the fan size calculator here to see how powerful your replacement needs to be: fan size calculator
I had left the shower running and had to attend to the little one and when I went back in there was a lot of steam and i'd forgotten to turn the extractor on. When I did I didn't notice much draw through it so opened the window and looked at the vent and it wasn't coming out with much flow. as they are just grills rather than sticking out like wall fans.

The unit jusst sits in the cavity with a cover and it draws in around the edges. It's mounted flush so that is correct but there is no ducting between the fan and outside vent, so I think it's just cavitating as apposed to drawing.
We have a large towel radiator and electric underfloor heating so the bathroom has always been dry but now I know the extractor isn't working as it should it's bugging me
