This is one of our first DIY projects, thank you in advance for your help!

We removed an old baseboard of the heating system in the bathroom and were left with a horizontal gap in the tiles. As you can see, the gap between the tiles and the drywood gets up to about 1 3/4" at its widest point.

We heard about grout, epoxy grout, acrylic grout, silicone and other options.

Which one should be best for this case?

    That gap is much to large for grout or caulking. The baseboard trim was the best solution for the improperly installed tile.

    Why do a half-way job? Remove a tile (e.g. slow prying), take it to a store that sells tile, get some matching pieces and a tile-cutter, and do it right. If you plan on keeping the house, you'll live with sloppy work for years, and if you plan to sell, it would reduce the value. May 25, 2020 at 20:20

    @AlaskaMan thank you, I forgot to mention that the (ugly) baseboard was of an old heating system which we no longer use. That's why we removed it.

    I agree with @AlaskaMan, that gap needs to be filled with a baseboard molding. May 25, 2020 at 21:52

    Fat base (3/4") and a big quarter round will probably make that disappear. Grout the last 1/4" at the wide end. May 25, 2020 at 21:58

Grey, sanded. 'black' is easy: #60 charcoal.

I'd grout it first though. I've had luck with a grout line that wide, and it was a wood-to-tile threshold nonetheless. A 1/2"-plus deep and ~2" wide? I'd go for it; that will seal the gap better too. Then base and quarter round.

I'm an all-or-nothing type of guy, but that's way too much all to get excited about what will end up being a slightly too wide grout line along the trim, of an otherwise serviceable tile job. - When you gut the bathroom though....
