Due to a "design issue" (AKA Cock Up!) I've ended up with a MHRV extract plenum in the shower area. From what I've read this is against best advise. Assume this is due to the levels of humidity in the ducting??
Is it an absolute "no" or in reality is it not too much of an issue.
Moving it is not an option now but I could change the bathroom design but it would be a considerable compromise.
TIA
