Extract within footprint of shower cubicle?

[Post and beam]

Is it acceptable to have the bathroom extract within the footprint of the shower cubicle?  The side panels will not go all the way to the ceiling so i cannot imagine its a major problem.

Two of three of ours are in shower footprint at ceiling level. Zero issues.

 

The other one would have been above shower, but we changed the layout and it ended up above the bath instead.

 

You will get plenty of contributions to this question, including you should never ever do it. Good luck!

For the same reason we now have this issue. The bath was going to be across the end wall that you see.

Acceptable and desireable subject to it meeting the correct IP rating

Does an MVHR extract have an IP rating or have I missed the point?

Zehnder's recommendation is that it should be close to, but not directly over, the shower. No reason given, but my guess is that it's not about the functioning of the MVHR unit, but rather that the air being drawn past the person showering could, in some circumstances, feel uncomfortably cool. For example if you don't have a good shower screen & door in place.

I think they’ve confused an electrical

extract fan vs MVHR outlet.

If under a warm / hot shower I doubt MVHR on boost would give you any discomfort in an open room.

 

Cant really understand any other rationale for positioning MVHR vents, other than to be as far (diagonally) opposite the door as is possible; to move the most amount of air through the room.

 

Maybe avoid steel vents and go for a powder coated aluminium if in the shower / steam zone, but I’ve not seen these affected by rust tbf as the constant airflow seems to rid the system

of moisture anyways.

Apologies, my fault for not being clear. Yes MVHR extract

The WC will be at that far end of the bathroom and is the opposite end to the door so thats settled. grill is going in that airtight box above.

Thanks guys

There's scope for some consumer testing here - just don't post the photos :)

You know you’ve got problems with cold draughts when your ‘outy’ turns to an ‘inny’
