I'm a painter by trade, and I tried posting in paint talk but they said my question would be better asked over here.

I know someone who has a bathroom with a wood floor and she wants me to put a stand up shower in. I'm going to use those wood looking tiles and liquid nail them to the floor for where the shower goes. I was thinking I'd do that and then use a hole saw to drill a drain in and seal it all up with silicone. For the walls I want to use FRP. The lady is on fixed income so we have to do this cheap, but we want it to look good.

I'm not sure if the FRP panels will be fully waterproof or not. If I paint them with some exterior paint I have left over from another job will that be good?

The floor will need a slope to drain, so a properly packed in preslope, liner, and slope will be needed. OR a precast shower pan (cheaper). FRP panels have their place, but it will need backing such as concrete backer or greenboard. FRP panels can be used in a wet area if the proper joining pieces on the flat and corners are used. I'm just not a fan of them. Figure the cost of the backer board and the FRP panels, then compare it to the cost of the backer and 12 x 12 tile. Easy to do and we can walk you through it.

None of what you mentioned sounds like a great idea to me!
Pictures of what's there now would sure help.
#1, What do you really mean by a "wooden floor" ?
Hardwood, plywood?
#2, Those panels are water proof but all the seams are not and it will look like poop.
#3, Why not a one piece shower unit?
#4, Before ever considering using that type tile I'd want to know how flat the floor is, what the spans, and width of the floor joist are and for sure would never consider using constrution adhesive!
Using Strip LVT flooring would eliminate most of the issues.

I'm not sure what kind of wood it is. Probably some kind of fir or oak. It's planks.

The house has a really narrow staircase that we can't fit a one piece unit up. I have some plywood and 2 x 4s out back I was going to build the enclosure with. And I saw on craigslist someone has a bunch of FRP for cheap.

If I use that paintable silicone caulk and paint the FRP panels that should be waterproof right?

If you're going to tile a shower floor you can't use liquid nails. I would get a cheap preformed shower pan and forget the tile floor. I've used FRP working for a contractor building walk in refrigerators. It seems like a convenient solution, but I don't think it would look very nice. Painting the FRP would be a horrible idea IMO. Water would only get through the seams and after having handled those FRP moldings I wouldn't trust them to be waterproof, and if you tried to silicone them in place it would probably leave a residue all over the surface. FRP glue is a nightmare too. You could use a shower pan and tile the walls. From how you described this project, you may need to watch some youtube videos on this sort of installation.

The surface of FRP is really glossy and slick. I don't know a lot about paint, but I don't think it would adhere and doubt it would last in a shower.

I appreciate everyone's advice.

But what I'm going to do is use polyurethane sealant instead of liquid nails to adhere the tiles down for the shower floor. Because that's what I got in the back of the truck.

You are setting up a disaster, so please do it right or get someone else to do it. Laying tile flat on the floor provides absolutely no water proofing and absolutely no draining ability. You won't be doing her a favor.

Yeah, that makes sense that the tiles can't be too flat or the water won't go into the drain and it might get all over the floor. I have some leftover asphalt roofing shingles in the basement that I can use to raise up the edge of the tile so it all has the proper slope. Do you think that would be alright?

You are joking, right? Is this Candid Camera? Where's Allen Funt?
Folks, I think we have a troll here...
