Waterproofing Plywood Shower Walls in a V-Nose Trailer

[S. Heisley]

One more tip: When you cut your fiberglass, spray yourself generously with hairspray. Spray your clothes, arms, chest, etc. and yes, even your hair. When you're done cutting, take a shower and all those little pieces stuck in the hairspray will wash right down the drain. (My niece used to work in a fiberglass factory.)

Maybe consider MDO(Medium Density Overlay) plywood. It has a resin-impregnated paper overlay that's water resistant. Think marine grade plywood with a resin sealed surface. It's super easy to work with and has a smooth paintable surface.

My carpenter cousin turned me on to it a few years ago. He uses it for outside cabinets.

I built my entire trailer out of the stuff. No fiberglass, PMF or aluminum siding. Just make sure that all edges and screws are completely sealed. I used bondo. Then painted the whole thing with rattle can white gloss Rustoleum.

I'm sure others will have difference of opinion on MDO, but so far I have no complaints.

I am building a shower in the v nose. I have walls framed in and sheeted with 1/4" plywood. What can I seal the wood with to make waterproof? Not doing any tile. Was going to use aura defense but the tub says not for use on plywood. Any advice? Thank you

I happen to be working on the same thing right now for my foamie. I have a harbor freight trailer. I wanna build a platform that will extend it out another 6 inches that I can raise up full height, but then collapse down for driving down the road. I found a nice 40 L gray water tank on Amazon, which I think I’m going to put underneath the shower floor and put a composting toilet in that can be removed when it’s time to take a shower. I have an Amazon portable shower thing that just uses a 5 gallon bucket. It has a hot water heater and the water heats up in about four minutes enough to take a shower with 2 gallons of water, which seems to be plenty.

Of course since I’m a foamy guy I’m going to build mine all out of 2 inch pink foam from Menards and it’ll be a separate room that can be removed off of the front hitch. As I’m sure you’re aware it’ll also make great storage for travel.
I’m still working out the door which I have several options between a canvas or net door or door made out of foam or something that I purchase but with the rise up type construction, the door is a little more complicated.

The height inside the shower/bathroom will be 6 feet which is enough for my wife and I are 5’6’ max

It’s interesting to see that you’re doing this. I did not see any pictures. Do you have any? I would just be curious.

Why double sided tape?

It was easy to use, no special skills or tools required and if I ever need to remove and replace it makes it simple.
