The room has very little color and no pattern--you need to think about that first. Then mount the tv higher and in the corner use a floor lamp if you need the light or just some framed artwork--maybe 2 pieces of art one above the other. Also you might want floor length curtains.

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

Maybe look beyond the footprint of existing bathroom. We renovated a bathroom where we were able to have a seperate large shower and keep the bath by incorporating a built in cupboard in a bedroom room adjacent to the bathroom. New Free standing storage in that room has resolved any issue with the loss of the built in.

This two stage renovation included opening up the back of the villa for a large new living areas, and renovating the front of the house for a garage and more formal landscaping to the street. The villa needed some TLC, so bedrooms and other existing villa spaces were refurbished using traditional villa details. A pavilion style extension was added to the rear of the villa, to house a new kitchen, dining and living area, media room and study. A large deck flows out from the living areas and connects the house with a generous, private outdoor play area. A separate laundry/scullery and new bathroom were inserted into the villa where it meets the addition, and an ensuite/walk-in wardrobe was added to the master bedroom. BEFORE AFTER!
