Have one made at your local glass shop. Look in the Yellow Pages for the closest one to you.

That is good advice. They can do it very quickly. I think they cut the glass and then temper it for you.

Be sure to get a nice thick piece of glass, it makes a world of difference in the end result. I'm getting new glass for two wicker chests, which came with glass toppers way too thin to be used as bedside stands. You can specify the type of edge you want when you place your order.

Thank you so much for your replies. I will check those out this weekend..

moccasinlading, can you recommend a good thickness?

Bumping this up since I am now thinking of doing this to a new nightstand I may get since I spill water sometimes when reaching for my glass at night.

Peir One has all kind of different sizes although I don't know if they have 23".

Lynn,

Not sure if your night stand is round or has another form but a local glass shop can cut glass to any size or shape you need. If it's not round, either you make can a template or take it to the shop for them to do.

Be sure you have the edges polished.
