Hi, I'm new on here. My friend has been diagnosed with cancer and I'm trying to help him. He attends Penny Brohn. He's looking for a water feature that can go in his bedroom. Ideally, the pump wouldn't be noisy. Preferably some kind of stone pebble trickling, tinkly kind of thing that would be soothing and therapeutic. We've both looked online but not seeing anything at the moment that captures exactly what he's looking for. Any ideas?
