Welcome BTH.
How long is your bubbling sound? And what program are you using to create your wave file?
I use Sony Sound Forge to create my seamless loops but I know there are some freeware programs that should do the same thing.
Here's a link to a 1 minute 39 second loop that I've used before. It's a 3mb download (256kbps bitrate).

If you string multiple copies of the file into a single long file by copying and pasting, you should be able to get the length you need without the gaps.
