This is a waterfront home and the fireplace seems dated to me. I will be replacing the furniture in this room to be more coastal - light, natural, airy. The bookshelves are not built-in and will be taken out as well.I am design-challenged, however. I definitely want to replace the fireplace door, but am also wondering if I should do one of the following:

1) rip out the entire mantel and use tile and reclaimed wood for a mantel, like this: https://www.houzz.com/hznb/photos/sunrose-beach-style-living-room-san-diego-phvw-vp~139292278

2) paint the mantel white and use tile, like this: https://www.houzz.com/photos/my-houzz-calm-crisp-neutrals-in-a-renovated-1887-chicago-house-beach-style-living-room-chicago-phvw-vp~131483479

3) Leave the wood as-is (since there is some other natural wood in the room, such as the high shelf and the railing on the "bridge") but still use tile where the black part of the fireplace is and the hearth (assuming that is possible).

I would love opinions and suggestions. Thank you!
