Shower – Grout recommendation and how to get at corners

groutshower

I have a shower where some grout has fallen out at the corners, where the walls meet the floor. I went to home depot and they sell a few types of sanded grout (the gaps are 1/8" or more).

I saw a brand named "fusion pro" which does not require any sealer, so it's just one application. Has anyone used this kind? link Or would you recommend sticking with more traditional types?

And lastly, can anyone recommend how to get the grout into these corners? All the videos I've watched are on the flat wall faces and use a float.

Thanks

That grout looks like it should work, the problem is that most grout require you to take out most of the previous grout. Certain groups, such as Mapei flexcolor, is built so you can add more to previous grout jobs, but it might have to be the same type.

As for the corners, you should use a colour matched caulking rather then grout. This allows for contraction/expansion. Most brands of grout have caulking in the same colours to make it easy to match.
