We changed our 2nd bathroom into a walk in closet because we needed storage more than a 2nd toilet. Had a professional plumber and contractor take everything out and cap things so it could be converted back to a bathroom if we sold and someone wanted that.

The plumber sealed the toilet drain with something like this at Home Depot, “4 in. Flexible PVC Standard Test Cap for Cast Iron and Plastic Pipe”. A cap that’s sealed by turning the screw on the wire tighter.

It doesn’t smell bad in the closet, but it smells different and I am obsessing that maybe the toilet cap isn’t fitted correctly.

What are the considerations around this type of project. Do you have to cap the shower drain too? What might be the cause of a smell faintly of ripe bananas?

The shower drained should be capped too because the trapp will not be refilled with water and will dry up allowing the smell to come up

All of it should’ve been cut off below the floor and below the traps in straight run areas of pipe and capped not with something like you’re describing but something much more rugged

He capped all the things, I just think the toilet cap is not totally sealed. I taped a piece of thick plastic sheeting over it and then put something flat and heavy over that. The smell is gone. So that tells me the cap wasn’t seated all the way down or something.

It’s meant to be reversible some day. Are you supposed to use a sealant with a cap like this?

No sealant. I did know what you meant. It’s more a temp fitting not for long term use really. I was thinking cut the pipe below the floor and install a screw terminal/clean out. These pipes shouldn’t really just be capped poking up through or even flush with the floor that’s not great if they are.

Never heard of anyone getting rid of a bathroom to make more storage space. Yes, cap every drain, too late to consider what the loss in resale value will be.

The shower drain and the toilet drain are connected also the sinks drain for that matter all three should be capped off. If you plumber didn’t cap them I would get him back out there too or better yet get a better plumber too do the work right
