I recently remodeled a bathroom. The shower was tiled in seafoam green glass tile, with a  niche tiled in 3-dimensnional bubble glass. My idea was to have candles in the niche to make the shower experience more ethereal. They needed to be the right size, right cost and fairly water resistant. many candle sets came in varying sizes, which would not work. After searching several websites, I found these, and immediately ordered them. I am extremely pleased. When I don't want them in the niche, they work beautifully on the window sill or vanity top as well. I believe I ordered eight so that I would have extras if needed.
