ᐅ Wide silicone joint – can I replace it with grout?

Hello everyone,

A rather wide joint next to the shower has failed after only 4 years (it’s cracked and has some mold). What would be the best way to fix this?

I want to avoid silicone again because it probably won’t last long, and the joint is simply very wide. How about using tile grout? Or is there something better, like joint compound, etc.?

Thanks and best regards,

Stop! Once you use silicone, nothing else will stick. Also, silicone doesn’t have to be inferior; PU can mold too, as can MS polymer—the problem in bathrooms always remains. Such a wide joint requires silicone with low shrinkage. I would use Elch Pro tile silicone from Henkel. Elch silicones are quite expensive, but the types used in shipbuilding are all top quality, durable, and dimensionally stable, even under UV exposure. That’s why I trust Henkel to produce a premium product for bathroom use as well.
Where can I get this? I searched online but couldn’t find it anywhere.

Me neither. I can’t find it on the market. But it does exist or did exist? Maybe it is now sold under Pattex Bad Perfect?
