I do, but not by choice. Mornings suck.

Wrong grasshopper. Particle board was the preferred underlayment in virtually every home in the south built between 1970 and the mid '90's. I see it in every job I do. You just rip it all out and start over. Two drops of water and it swells up like a sponge.

On a bathroom remodel, we have pulled the tub, vanity and existing tile. The existing floor is two layers of subfloor, but both are particle board.

My current plan is to remove the top layer and replace it all with hardy board... and then here starts my questions.

1) I have only heard one person say that they glue the hardy board to the lower sub-floor later, this sounds crazy, I would use many screws to make sure there is no squeeking.

2) The most important question I have, for the shower stall, I am planning a curbless entry with a forward slope to the shower doors. I am using the QuickdrainUSA product which so far seems like a good way to go. I am using their 58" linear drain and their quickslope product and the kit they supply for waterproofing.
Their instructions report to put thin-set directly to the plywood, then lay backerboard (I assume hardy) , then right onto the hardy a layer of thinset and then their quickslope material.

I have in the past been under the impression that you should always place tar-paper with mesh on top of the plywood, and then any cement / thin-set or mortar or anything like that otherwise the wood just draws all the moisture from the thin-set.

Does anyone here have any view on these questions?

Thanks
WOW... there is so much about this thread that tells me that your clients' lawyer will be contacting you in about three years wanting his money back and his bathroom rebuilt.

I glue the cement board down Hardie board or ideally Bond it with thinset and screw it. And then my favorite top-of-the-line product Red Guard! Anywhere there could be a moisture issue.
