I'm redoing my shower caulking and this door threshold part got unglued. The photo shows it from underneath, and we can see a groove that was filled with what looks like silicone. Should I just use my silicone caulking as glue for putting it back in place? It's a Maax shower.

Thanks!

Clean all off all the old caulking, then reinstall with silicone or siliconized caulk?

Use anti bacterial Silicone. I am recaulking my shower for the 3rd time after mold got into the silica.

3rd time in 3 years?

This is an unpopular idea but the reason the caulk between a tile wall and the tub gets moldy/fails prematurely is because the tile grout is porous and the water travels down [osmosis] until it is trapped by caulk at the tub. The constant wet spot allows mold to colonize.

It has become "common sense" to caulk that interface but if you were to remove the caulk the mold would not form.

OTOH to use nothing there requires careful waterproofing at the level behind the tile. A properly constructed shower should be functional/waterproof before any tile is installed

That's what I thought but I wasn't sure, thanks a lot!

He is right. Just make sure you clean the tub area that's your gluing too really really. Also wipe it with alcohol to make sure no residue remains for other cleaners before reglueing.

Glue it using a continuous bead of a silicone caulk. Also run a bead on the sides inside of the shower where the track meets the shower. Let dry for 24 hours before use. A bunch says you can go sooner, but if it gets touched or anything you can disform the beads you've run or even bump the track back out of place as it's not fully cured.

Clean it well, use a high quality silicone , and apply the silicone liberally so water can't get under it and produce mold.

Typically these enclosures only get caulked on the outside of the frame. I just spent way too much time over the last year looking into these enclosures.

This. There are drain holes on the bottom that need to be able to flow to the inside.

Thanks for identifying this part for me! I knew I needed to replace mine but could never find the right words to google…

It’s a shower door threshold. TYSM! Good luck with the install.

I think most shower doors thresholds like that are in fact just meant to be stuck down with silicone caulk. So yeah, just get all the old caulk off both sides and stick it back on there.

Probably pay special attention to looking for potential leaks at the ends, and make sure to get the silicone in there such that it seals it up the sides a bit too.
