Hi Folks-
This is the first of two posts concerning the installation of a new whirpool tub, an American Standard Williamsburg Elite 5' with integra apron. I'm splitting up the posts because they are on different subject areas.
This is my first tub installation. Demolition and removal of the old one (a plain steel tub) took much of the weekend. Quite a learning experience.
Anyway, here's my first question: How exactly do I set up the mortar bedding?
The installation instructions for the new tub say:
"This bath is not self-supporting and must be supported along it's [sic] entire bottom. Support with mortar or grout. ... We recoommedn the use of mortar as bedding material (sand is not recommended. Apply enough bedding to support the complete bottom of the bath. After the bedding has been poured, and before it sets, position whirlpool or bath within recess... allow the bedding material to completely harden before applying weight to the rim or bottom of the bath."
There is a diagram, that just shows an amorphous area representing the bedding.
What do I do, just mix up a bunch of mortar and slop it onto the rough floor? The instructions give no indication about how much is needed, or how to contain it in the area needed, or even the dimensions showing exactly where the mortar needs to be.
Should I put a plastic sheet down directly on the rough floor to make it easier for the next guy to pull this tub some years from now, rather than having to rip the tub out of the mortar?
I'm a little freaked out by this mortar thing. Any advice would be much appreciated.
Thanks
Marc
