[Stick-man]

Piss outside?

Well yeah, but if ya gotta drop a deuce...........
I don't want to have to go to the house and track dirt/grease.

I think I am going to go with this. Only $26 per 4'x8'x1/16" panel.

Whatever you do, be sure to roll on a coat of waterproof membrane on the cement board and seams before you cover it.

I have used this (kydex brand) and FRP in commercial kitchens and baths (general contractor). Since it is thinner and less “reinforced” it will show all the uneveness in mastic application (or wall finish) on the wall. If you just “squiggle” on panel adhesive from tubes, all your squiggles telegraph through. Proper instructions probably indicate full mastic with v groove trowel.. and it will likely still look “wavy” (oil canning). Still a good idea, just setting expectations.. you get Less of this issue with FRP (but more itchy cutting it!)

Now that I think about it, a fully tiled bathroom with a floor drain and a powerful exhaust fan would be a perfect design for its ability to be cleaned in about one minute using a pressure washer.

Try pointing a reasonably powerful PW at the grout and tell me how it goes.

Thank you! I wasn't thinking of that.

If that's the case I guess I either go with the FRP or might as well just caulk between the seems of the cement board, paint it, and be done! This is a small shop, and it's a WORK shop! NOT anything of a show piece. Most of the small shops around me have plywood walls and door for the bathroom's. LOL I was going to do it a bit nicer, but I am function over aesthetics in the end. The next shop I can do it up. Decision's, decision's, decision's! I could have sworn there was a panel that was basically masonite, with a tile looking finish on one side for just this purpose. I can't seem to find it online, or I'm using the wrong search terms.

...I want to be able to use a hose for cleaning...

...I could have sworn there was a panel that was basically masonite, ...

I can't think of a worse combination!

I said this is a temporary shop, until I build my forever home and shop. That is why I am looking for the cheapest possible solution.

Then why even fret about it. Leave what's there, there. If it gets dirty worry about it then. Ask you wife how often she wipes the wall done next to the toilet.

Yeah, tile is not waterproof at all.

The poster above who mentioned what most of the world does skipped over that most of the work doesn't build like we do in the US...those bathrooms are probably mostly concrete block walls

It had a coating on it, and it looked like 4" square shower tile on one side. Not sure what material, but it was thicker like masonite. Yeah, I guess that was a bad description. LOL I am well aware of masonite getting wet.

If you really want cheap, Amazon has a ton of "Shower Tents" for under a hundred.

How about using a roll on bed liner material, I just used some durabak & it seems indestructible. Durabak is a little pricey but there are cheaper ones & this stuff will cover joints & corners nicely.
