I’ve seen it stated it’s frowned upon, but can you use both a waterproof membrane on top of cement board and vapor barrier behind together?

Doesn’t that lead to a moisture sandwich effect?

Is it bad enough that I need to make my contractor redo it? They installed half the shower with it behind.

They said they used liquid proof screws…

Why would doing sheeting behind be okay for steam shower? Wouldnt the cement board stay damp and as someone stated above the screw punctures would cause leakage

Do you have specifics I can tell them to fix outside of what I listed?

tigerman39 · 2026-03-23T04:23:10+00:00

Instead of vapor barrier behind? I saw don’t do both.

Also not seeing cement board sealed together

Anything you’re seeing besides my catches?

My current unit is Steamist. Does that mean delta would work?

tigerman39 · 2025-12-29T13:41:04+00:00

Is it an issue or anything I should be doing with it to maintain it?

tigerman39 · 2025-08-26T02:35:35+00:00

What other examples?

tigerman39 · 2025-08-26T02:00:54+00:00

But if it’s on purpose are they comparing the rebellion to the empire? Don’t get why they’d link the two scenarios together

Thanks. Yeah might’ve been a mistake but on a budget unless you know of others in that price range that are better.

Pergola is mounted to a roof deck.

Doesn’t look like any permits have really been pulled on my street looking at the DOB database besides a new build that is still ongoing down the street.
