door is 32" wide, and opening is only 30" after pocket door installation. I am thinking contractor needs to make the opening larger closer to 32" which is the width of the door, and would correct the uneven look on the right side of the door.

Door stiles cannot be made to look even if a standard off the shelf door is used. The stiles need to be sized accordingly as a custom door for them to be the same. The one side sits in the pocket slightly while the other side hits the jamb. The exact dimension escapes me but the door will be off about 1 1/2" if I remeber correctly. Or just like you have shown in your pic.

Looks right to me. I have 2 pocket doors left out of the 3 I had. Part of the door does sit in the pocket.

why all that space under the door? a cat can go through it

This is why flush doors are the best choice for pocket frames. If you choose a paneled door, there are tweaks, but they might not completely work and depend on the particular door, the particular frame, the type of door pull used, the skill of the carpenter and your wallet. The latch side of the door might be able to be planed off an inch or so. Depending on the pull, the latch side might be able to slide between stops applied to the jamb. The split jamb on pocket side might be able to be slimmed a bit.

I hadnt enlarged the picture before, and I just did after reading dyliane's post. It does look like the door was trimmed too much, or ordered shorter than it should be, thats a whole lot of space. I would not like that.

No personal experience with pocket doors, but it occurs to me ... .

If it's the visual symmetry that disturbs you, you might ask your contractor if changing the vertical trim on the left side to use a wider board would interfere with the operation of the door in any way. Otherwise, the only visual fix might be vertical stripes on this wall or in this hallway as camouflage.

thanks for your comment, and you are correct. Hopefully the gap that has been left is sufficient for floor sill and air.

Thanks to everyone who took the time share comments. BTW...Upon closer inspection of the door, we also noticed the door jam on the left is not completely straight either. The dimensions from trim to trim on the outside vs. the one on the inside of the bathroom do not have the same measurement either. I believe it needs to be redone, hopefully the trim on the right can be moved back to enlarge the opening to almost 32" which is the width of the door minimizing the uneven look.

a tile on the floor won't cover all that gap. for me the door is too short
