A: Hello Boo,
Thank you for your question about our Tub Door. This door will fit any opening from 50 1/8" to 59 3/8". A standard tub is usually around 60", but some space will be taken up by your wall (drywall, tile, etc.) The important thing to do is measure your opening from wall to wall and make sure it is in this measurement.
If you have any other questions, please call us at 1-800-964-4850.
John,
