Thanks so much for this post sheilapillai . I didn't think of that when considering adding sliding doors in living room. Didn't do that yet, hence is why i thank you. This is a tricky question. On one hand i want sliding glass doors to accept as much natural light as possible (solar heat), but not too big as too lose our furnace heat after the Sun sets

Are they closet doors? What about the louvers don't you like? Replacement costs are probably cheaper... http://www.lowes.com/pd_201659-32998-41065_1z13eny__?productId=3040848&pl=1&Ntt=sliding+closet+door

I think a different look between the two rooms would be a conversation starter! Try not to be nervous if you can.

I have a similar sized ensuite in my own house and would definitely not put two doors in it. You will probably find that a fixed glass panel to half the width and a glass door the other half would work fine. Alternatively you can get a sliding glass door (again 50/50) if you like the look of them as they do save on space.
