We have limited space in the second bathroom, as far as the tub/shower enclosure is concerned. No shelves of any sort and nowhere to sit any bottles. We had a small shelf unit that hung on the shower head. When my husband purchased a new hand-held shower unit, it didn't allow that shelf unit to work there. The hose to the handheld shower fixture was too rigid and the shelf wouldn't fit. That left us with a small corner of the tub top edge to perch a tension caddy. There's precious little extra space there. It just fits. Plus we have high ceilings, so we had few choices. It works for us.
