Not to be rude, but I usually dislike these types of videos. Testing the product and simply reviewing it are entirely different things. I find it hard to trust this video.
I've got the barrel tub. It fits in my shower. I've had it years. Nice and warm, lovely. Cost me 35pounds from ebay. Downsides, I'd like a bath I could stretch out in but we only have a small space so it's the next best thing. I think they are about 48 pounds now, or thereabouts. That's only the barrel ones. The long ones like the inflatable tumble is 100pounds or 80 $😊
