New install design help

So I have a new 3 bedroom 2nd floor I'm looking to install radiant in I'm going to go with the staple up method with aluminum transfer plates. My question with 1/2 pex and and 8 inch spacing will this be sufficient enough for the bathroom with a tile floor I was thinking to install a back up base board for the really cold days

    What is the heat load of the space? All calculations for any heating system start with the heat loss. Get that calculated then the experts will be along to help you out.
