Bathroom Caulk

Basil48192

I have a 2021, 320S.  I am having trouble with the caulk joint where the horizontal toilet platform meets the wall.  The first time I repaired it, I used a silicon caulk...which did not adhere to the plastic components very well.  Next, I used a more conventional DAP kitchen and bath seal (non-silicon).  That adhered well but was not flexible enough and the bead split after just a year.  
Does anyone have any suggestions?  I was considering a 3M Marine Adhesive Caulk...but thought I would check here first.  Thank you in advance!

I'm interested in this thread. My 2022 TAB320 BD has a similar issue. The caulking joint between the wall and the toilet "separated" on our first year of use. We're not using the shower so less of a concern but I still want to fix it at some point.

I'm assuming that the toilet platform is polystyrene...and silicon will not adhere to it.  After doing a lot of searching on-line, I'm going to try the Loctite 2 in 1 adhesive caulk.  One posting stated that this is one of the only products that remains flexible and will adhere to polystyrene.

@Basil48192 Looks like you got the right one!  I found that discussion about all kind of caulking:  https://tab-rv.vanillacommunity.com/discussion/16031/caulking-and-sealants-what-nucamp-uses

@Dame_plume, thank-you!  I did a number of searches before posting and never found that!
