Which bathroom sealer for removable plinths?

[velodocuk]

I've got two removable tiled sections in my new shower room - one for access to underneath the front of the shower tray and one caps the boxed in soil pipe (air admittance valve type).

I'd like to seal the joins but preferably with a sealer which would be relatively easy to remove if I need to remove the sections.

Silicone bathroom sealer can be difficult to remove tidily. Can anyone suggest an alternative for this particular use - decorator's caulk?

Thanks, Paul

No, it doesn't look good unless painted. Silicone is usually easy enough to cut off with a sharp knife and if it's going to be re-sealed after access it'll look neat enough.
