Caulk around toilet?

Hi,
I just traded in my older t@b for a 2021, and noticed that there is not caulking around the lateral sides of the toilet tank. Is there any reason NOT to caulk this?  Wanted to caulk the interior of the bathroom before I take a shower.

    Yes, the reason is that this panel is removable, for maintenance access, like checking the Alde glycol level.  Don't caulk it.

    Ok, I was wondering about that. I’ll stop caulking everything.

    If you are really worried about infiltration, you could install a gasket of compressible foam weather-strip between the panel and the wall. That's what I did when I had to make a new access hatch behind my toilet.

    I'm not sure if it's necessary, or if the panel doesn't already have a gasket.

    That’s a great idea. Maybe I’ll try that. Just seems like mold and water will quickly get back there.

    If you remove the panel, there should be caulk on the panel that's underneath to keep water from getting where it shouldn't.  Any water that gets in the edges of the access panel will just run down and exit the bottom.  There's a thread with pictures showing this - I'll try and find it and paste in here.

    Here's the comments on caulking the panel underneath.  I caulked mine myself.  My T@B was #8 off the 2021 line and I don't know if they added this caulk procedure to there process but from the picture, hopefully you can see where the caulk should be on the sides that keeps water out of the interior spaces behind the toilet.

      Sharon_is_SAM,  I was referring to the panel in the picture below that has the large oval cut out of it.  Notice the crack along the far left side edge, there's one on the right to.  The access panel screws into place and leaves a similar crack.  Now if water goes past the crack in the access panel, it will head right for the crack in the panel that you see below and water will sit on the plys of the plywood.  But if the crack you see below is caulked, the water drains down to the toilet that has a seal that will let the water come out onto the toilet and be wiped up.  So when I looked at it, I figured the thing to do was caulk the sides of the inside panel you see below.  Granted, unless you use the shower a lot, and actively spray all around, its probably not a big problem but I was just being thorough.  It would be interesting to know if NuCamp's manufacturing process actually has them caulk things this way.  When I studied the shower stall, I noted that they did take the time to caulk everything else which tells me they are interested in stopping water exposure to the edges of the wall material.

      Now I see.  The surround should be sealed/caulked and the panel should float.  I will pass this on.
