Greetings and welcome, good to see another B+.
The previous owner of our 29TB let a large leak ruin all the trim.
Like all cardboard, setting in water will swell like a sponge
After spending hours online/lowes/homedepot looking for trim good ol Amazon
I took all the trim off the living area, cut about a foot of good material off and put in the bedroom.
This is what we used.
Didn't try to match the color, went with a darker color.
Took a few hours and $$.
