Too small for a curbless shower unless you make the whole bath a wet room, which is a fine option, I believe. It is too small for a wheel chair so why not do a shallow curb and frameless glass door? My shower going from curbless to small curb, it is on a second floor so if I can not get over a two inch curb I am most likely not getting upstairs either, saved me thousands( closer to ten than to five) of dollars...

The only advantage I can see, if not handicap accessible, to the curbless is being able to use the same flooring throughout the whole room. Why have a change of tile if you are doing curbless? Save the money, otherwise.

I have to second what Roarah says: This room isn't big enough for a curbless shower. I'm not sure I remember the numbers right, but I think you're required to have a 1/2" drop for every foot, and the lowest point in the shower (the drain) must be 2" lower than the door ... which means you must have 4' each direction for a curbless shower. Again, my numbers might not be perfect, but the concept is something like that.

It's better to use a curb than to have curbless-done-wrong.

Another problem to consider ... the pocket door won't work for two reasons: 1) pocket doors work great for doors that are rarely closed (closet, toilet closet, laundry room), but bathroom doors are heavily used, and a pocket door will break ... and then you have to open up the wall to fix the door. 2) you're going to need plumb lines in the same wall where you're planning to place this pocket door. You really need to go with a swing door.

Finally, 27" wide and a 22" wide door are small for a shower.

Is there no room to expand into to make a large enough bathroom?

I showered all my life,until last year, in bathtub's some narrower than 27 inches I think it will be fine. The 22 door I am not sure about but a lot of tub/shower combos have sliding glass doors so I imagine it works.

Minimum dimension (building code) for is shower is 30" if that matters to you. There is some leeway if the shower is long as yours is. It needs to be sized/shaped so a disc 30" in diameter can lay flat on the shower floor.

Mongo is that at least one direction needs to be 30"? A very common shower base size is 27" x54"...

Could you possibly push the shower to the other end and use a wall hung toilet? Then the floor could be sloped near the toilet without affecting its level. And at that end it may be okay to use a curtain rather than glass which would give a bit more elbow room.

I think the shower compartment exception has to be in place for alcove bathtub shower combinations, because a standard bathtub with glass door will not end up 30" on the interior.

I think this is one of those things that may be open to interpretation and may also have more stringent local requirements such as: a locale or inspector allowing this exception for a bath alcove installation or the direct replacement of an alcove bath with a shower receptor but not as a separate freestanding shower compartment.

"Mongo is that at least on direction needs to be 30"? A very common shower base size is 27" x54"..."

The 27" x 54" meets the 1300sqin exception, just make sure the exception applies in your area. The town I live in does not allow it, but when I was working in NYC and SFO it was allowed in both places.

was wondering about the 30" code requirement for the shower stall. But what is the point, considering the existing door way opening to the bathroom is only 24".

palimpsest - Interesting concept. Will seem to be picking up a little more width for the shower. Have to pass this along to the boss (wife) for discussion.

24" for a doorway into a room is very narrow. With Pal's version you could at least widen the doorway

I'm afraid adding a curb would make the shower narrower. To contain the spray, is it possible to put the entrance to the shower at the back instead of the side? For example, going from palimpsest's proposal, could you have a curbless shower, putting the plumbing on the wall where the window is (if it's allowed where you live) and walking in from the back of the shower (close to the closet)?

OR

Could you reduce the length of the vanity a little and move the toilet so you can put a curbed shower across the back (you may have to waterproof the window)?

okay - have been busy rearranging a few things based on the great suggestions received. Lasted layout, below. The vanity is a little smaller but gave up length for a large shower. Sorta following this photo

I think that's a more functional layout.

You still need more than a 24" door to get into the bathroom Make it a 30" door at minimum!

Also realize that 22" for a shower door is the absolute minimum. It will be tight for anyone who is slightly larger than average.

Also what is the distance from the edge of the toilet to the edge of the linen closet?

Jirpel , My bathroom is exactly the same size, only my door is 28” swing door and window is in the middle of the the wall. What did you do?
