If you are worried about protecting the sub-floor using a membrane
material (shower pan liner) would probably be easier.

The OLD bathtub was cast iron.
It was 60"x30"x16" and an estimated weight of about 250 pounds (dry).

I'm going to be installing a jetted tub within this 3-Wall
nitch/cove of about the same size (60x30x20). This new tub will be
acrylic/fiberglass, which weighs less than the old cast iron tub I
removed.

My question is... Would installing ceramic tile UNDER this new tub
HELP with protecting against water damage to the sub-flooring... or, am
I asking for future trouble by ending up with a bunch of cracked tiles?

I don't really know the weight of the jetted tub... but I will
get back to you if needed. (I'm looking at the Jacuzzi Luxura 530,
#N790). Thanks in advance!

God bless,
