I have this one. It's pricey (now! It wasn't way back when) for a bucket, but the gasketed screw-on lid does a good job of sealing in odors if you have to transport the used wag bag (gel powder type) back to civilization
inside your vehicle (I camp in a minivan.) I keep a couple spare wag bags in the bottom, put a heavy-duty garbage bag inside as a liner, wag bag inside that. Ziploc the used wag, twist- seal and twist-tie the trashbag, throw TP roll & flushable wipes on top, tuck the foam seat inside, twist seal the bucket. All contained, and pretty dang odor-tight. I find snap-on lids that are tight enough to seal can be a real pain to take off, especially with hands frozen from cold weather fishing. The design of this one makes it easy to seal/remove. The foam seat is comfy, and the bucket is extra sturdy.
I think you can just buy a gamma-seal lid on Amzn for like $20 if you have a bucket and don't care about the seat fitting inside for storage.
