Customer Reviews
Good for our caravan
I ordered the Solbio 1.6 litre pouch for our caravan. It got here pretty fast, like 4 days, which was nice since we were heading out soon. I was a bit unsure about switching from our usual stuff, but this worked out great. No weird smells and it felt much better knowing it's all organic. Used it in the waste tank and it handled everything well. Definitely felt good about the purchase.
Works well, quick delivery
Bought the 5 litre container. It arrived in 3 days. Used it in the motorhome. Effective at controlling odor. No issues.
Worth the money, good deal
I was looking for a more eco-friendly option for our portable toilet but didn't want to overspend. I saw the multi-buy savings on the 10 litre bulk pack and it seemed like a good deal per litre compared to smaller sizes. Plus, I got free shipping because of the total. It arrived promptly, maybe 5 days to reach us, and I've been using it for a few weeks now. It's definitely holding up to its claims, no strong odors and it feels good to use something biodegradable. The upfront cost for the bulk pack was a bit more, but the savings per use make it totally worth it in the long run. Glad I went for the bigger size.

Share tips, ask questions & help fellow shoppers save more
Hey guys, thinking about grabbing some Solbio for our campervan trip this summer. How long does a pouch usually last? Trying to figure out how much to order.
Quick question on delivery, does Solbio ship to the US? Specifically New York. Saw it on a few UK camping blogs and it sounds awesome but not sure if it's a UK-only thing.
