I own a backpacker's hostel and currently use plastic/chrome shower heads atached to a hose and slide-rail in the handicapped bathrooms.
They tend to break very easily when they are dropped (which is all the time at my place!) so I've been looking for something more durable.
Initially I looked for stainless steel but I don't think you can get them because of the dangers of dropping them on a head or a foot so can anyone think of an alternative? I'd probably still try s/s ones if they're available.
