Hey There...that's totally right. Just a glass panel will not do the work. I went thru this myself with a new shower and I had to add a glass door at the end...you can also try to go with a sliding door - this leaves you the flexibility of closing or not...Good Luck

Agree that you will need a door.

Rimless glass enclosure with door will still give you the feel you are liking for.

I personally love the simplicity of not having a shower door. It keeps the look clean + modern. If you have the appropriate amount of tile / waterproof surfaces throughout your bathroom, splashes will happen, but won't be a practical issue, especially if the shower itself is sloped properly. The image I am using here has a chainmaille shower curtain that was installed as a back-up in case the water splashing was an issue, but ended up never being used.
