2 by 6 framing for shower stall

spring3100

Going to build a raised platform of 2 by 6's on end,with a 3/4 plywood base for a basement stall shower insert.

All of this will sit on concrete,any 2 by 6 would have a sill sealer attached to it.

My question is,should I use pressure treated 2 by 6's,or regular wood,or does it matter at all.

Thanks for the input and hope everyone had a safe holiday.

Location is the New England area.

if I was to do what you are going to do ...which i would not.....i would use pressure treated where it came into contact with concrete.....again only if i was to do it..

If it's on concrete then it has to be pressure treated.
What do you mean by a sill seal? Sill seal is foam that sets on a foundation before the mud sill goes down.
Use Advantec subflooring not plywood or OSB. Far more resistant to moisture.

Have to raise base in order to get clearance for the P trap.Doing a Saniflo installation and have plenty of overhead clearance.

Unfortunately,several factors prevent me from breaking up the concrete for a sewage pump.

Joe,

I'm putting the 2 by 6's on end,they will be sitting on the concrete floor.

Then I will attach a 3/4 inch base to that.

Then I will put the shower insert floor on that,and nail flanges to the wall studs.

I will set the shower base in a thinset mortar.

The sill sealer is going to be attached to the edges of the 2 by 6's where it meets the concrete as a capillary break.

Are you saying to use the Advantec in leiu of the 3/4 inch plywood?

Can you raise the floor not only in the shower but the whole bath and go outside as well so the step is outside the door with a landing. Have seen it done and looked like it was planned and belonged. Had same floor covering outside the bath door as rest of basement.

Yes I would use ceramic coated deck screws and Advantec not plywood. Plywood would delaminate if it got wet. Advatec holds up far better in contact with moisture and does not tend to mold up as bad. It's got a waxy coating on it.

Sounds good Joe,Thanks !!!!

(They will be on edge, not on end.)

I second Mae-ling's idea.

I cannot add a step up outside the bathroom.The threshold goes under a laminate beam (not moving that baby!).

And doing one inside would look rather silly.

As the shower is in a recessed nook,the step up shouldn't be an issue.
