Piano Monitor Shelf

I've read about the ready to hang shelves and so far find multiple complaints about brackets breaking shortly after arrival. I also fear that hanging a shelf with 4 screws on sheet rock will over-stress the sheet rock resulting in the shelf breaking off.

For that reason, I'm curious if the best way to go is to mount wood on the wall and then mount the shelf on that wood.

 

 

Referrals I'll need unless Hartwell now does this too:

  1. Wooden Stairs: It's been 17 years. Soil builds up. Even clean hands and feet leave oil that turns black. I can catch up on laundry, move potentially needed items out of the basement and move into one of the ground floor bedrooms for a week or two. Can the stairs be sanded down and refinished? Should I put that off until I'm ready to put this house on the market?
    (new: added 9/17/17):   I forgot to add that besides the stairs, there is also the small wooden floor which serves as the landing between the up and down stairs but also is the wooden area that I call the "media center".
  2. Basement cement floor:   the flooring in the exercise room and office were finished with an epoxy finish a few years ago and look great (or would if I used the electric floor washer). The laundry and boiler room are grimy. I don't know what options are available besides epoxy. I'd appreciate any thoughts.
  3. Tile: There's been a crack in bathroom shower tile. I don't recall the name of the tile guy who did this bathroom and the greenhouse 17 years ago. Do you have a new tile guy? There's also some re-grouting needed in the greenhouse.

This is all I can think of now. I'm sure I'll think of something else 5 minutes after you look at this and close it. Hurricane Irma has me stuck here but, as I said, work isn't as stressful as it used to be.
