Post and beam Posted March 30 Posted March 30 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.
JohnMo Posted March 30 Posted March 30 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!

Mike Posted March 30 Posted March 30 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.

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.
