I am in the process of re-doing two bathrooms. I needed to quickly get
at least one shower working so I installed an acrylic tub and a tub
surround. I caulked the thing once using ployseamseal tub & tile
caulk, but it failed. I figured I hadn't given the caulk enough time
to cure, so I took everything apart, cleand everything with bleach and
alcohol. Then I put it all back together, re-caluked, let cure for 48
hours, and it's failing again. There is six people in my family so I
am now thinking that that many showers in the morning is killing the
caulk job. Any recommendations on better brands of caulk?

I am amazed that you're having a problem with PolySeamSeal.

I've been using this stuff for over 20 years & I've never had it fail.

here is the link for the TDS

http://www.polyseamseal.com/products/tech-TUBTILE1.pdf

if you look at the limitations section

there are some words about "below the water line" & "constant water
imersion"

if the six showers in the morning do not allow caulk to dry out maybe
that is the problem

or if the shower / tub configuration is such that water can pool or sit
on the caulk?

DAP DynaFlex 230 is also another possibility

or just bite the bullet & go with a silicone.
