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?
