Pre-fab shower requires mortar underneath - what type?

Hi All,

I bought the "Jono Hudson 38-in. Neo-round Corner Shower" from Costco and will be installing it in the next couple of weeks. Page 9 of the instructions says:

"A bed of mortar must be applied underneath the tray of the shower base. Apply a sufficient amount to support the base when it will be leveled and fixed."

Any recommendations on what type of mortar to use?

Thanks for any help!

It's pretty forgiving. I generally use whatever I have on hand; premade mix, type S or N. If you have to go buy something I would get a bag of mortar mix that already includes the sand so all you have to do is add water.

Thinset is a good product. I use about 4 or 5 dollops spaced across the pressure area, so when I set the unit down, it will have room to squish out.

Thanks for the guidance - that should be enough to get me set up!

A follow-up question - I'm running the water supply lines using pex pipes (the whole house is run with pex). They'll be in an exterior wall - not ideal, but it's not really all that "exterior" anyways - it's a foundation wall we share with our neighbours (we're in a townhome). Not sure why, but it has insulation and vapour barrier on it. I plan to run the pipe on the drywall side of the vapour barrier, but behind the drywall (of course).

My question is - will the hot water line be too hot to rest directly against the vapour barrier? i.e., could it melt the plastic?

Domestic hot water is not hot enough to damage insulation or vapor barrier plastic. It's probably only 120-140f (49-60c).
