I'm looking into sliding shower doors and all the doors I see assume that you are installing to space which is the width of the tub. In my case, the end of my tub has a little shelf extending beyond the tub, around 4 inches length and 1 inch higher than the tub. Has anyone seen examples of installs with this?

  • If you install a 60" door into a space that is 56" then your doors will overlap 4" more than they typically do. A picture of the shelf would help. Jul 26, 2019 at 16:16
  • Yiu will need to add a short wing wall made of some water proof material on the left side, leaving an opening proper size for pre made doors. Or add a lip of water proof material to tub curb top making a plane even with shelf top, then order custom width doors.

Make a 2” return on each end or 4” one end to support the sliding units which takes up the extra space.

Now you have added the picture I would go for the 4” - designed to match the shelf or just completely box-in that end... but that shelf area could be useful....

Some shower screens don’t go the full length of the bath anyway - I fitted one that is 2/3 of the bath length which works fine for the shower.

  • I think he means the door is wider than the tub opening. Jul 26, 2019 at 16:16
  • @PlatinumGoose I think the OP means tub length plus shelf ie X + 4” ...

  • How does the OP do that ? I also think the question is that the opening is wider then the tub. I.E. wider then 60 inches.

    @Michael as I put in the comment above "these “returns” are small wall extensions", so, a small wall to take up the 4" space and provide a secure solid mounting for the sliding panel...
