I am building a new master addition to my house. It is not possible to extend ducting of existing hvac to the addition so we are going to go minisplit. The addition is 480 square ft, 280 for the bedroom, 90 for bathroom and the rest for his and her closets. I am worried that a single point mini split will not provide adequate hvac to the bathroom area. I also think that adding a 2nd zone to the bathroom may be overkill, not to mention a big increase in price.
I had an idea of installing a room to room in wall fan to circulate the conditioned air into the bathroom. Has anyone done anything like this? But the other part of the equation becomes if I do that, how would that affect the sizing of the bath exhaust fan. Should it be sized the same size or should it be sized larger to maintain a negative pressure to move air outside?
