Small bathroom good. it will work with regular hinging shower door. just make sure not too much air going out. shower door must go all the way up to the celling. and the celling must be waterproof.
that depends on alot of factors and is something that will need to be planned, not just added or else you could have water damage. First and foremost It will need 240v electric run to it and a water source. You will need a drain pan as well. An adjacent closet to house the unit or unfinished side of the basement if on a lower level is helpful. It is a must to have a fully tiled room or tiled and sealed enclosed shower.
