Cracked grout in centre of bathroom


Hi,

The grout keeps cracking in the centre of our bathroom floor. We will soon be regrouting for the 4th time in just a few months.

One of the tiles near the centre has a slight bit of flex in it.

Is an easy solution just to caulk the area with a matching colour? Would this last for a considerable length of time?

If not what is a long term solution?

Any advice appreciated

P.S. - My DIY skills are just above negligible, but I had enlisted the help of my dad to grout on one occasion in case I was doing it incorrectly!

Cracked grout in centre of bathroom


Well 99% of grout cracking is caused by movement. That being said what consists of the floor under the tile?... So how was the floor built?
There is not quick fix sounds like you have a bad subfloor.
Don't bother re-grouting its going to keep happening. Might want to start pulling tiles up for a redo.

Cracked grout in centre of bathroom


A picture of the area would help. As Jet's suggested, if it's moving then the grout will crack again, and again, and again. Tile and grout are hard materials, they do not flex. So tile put over a surface that flexes WILL crack. There's no practical way to eliminate the flexing of the subfloor once tile has been laid over it.

What is causing the flex? Is there a way to see the frame under the bathroom? Like look up from below? There might be some sort of structural issue that *might* be fixable in a way that could reduce or eliminate the flex. Doubtful (very), but possible. Could be a joist that was improperly cut for plumbing or something. There might be a way to fix it from below, but probably not.

Just running caulk in the gap will look like hell, collect dirt, look like more hell, and still not eliminate the flexing. The surround tile will likely start cracking eventually.

The solution is remove the tile, find out what's causing the flex, FIX THAT and then put a new floor over it. Putting down a proper subfloor and using proper tiling materials (schluter or hardibacker, etc).
