I think it depends on so many factors we're not privy too. For instance, do you and your spouse use the bathroom at the same time? We only have one sink in our bathroom but we've never found it to be an issue because we just don't use the bathroom simultaneously. Do you have another linen storage area somewhere in the house?

I really prefer the first option because the separate shower and tub are so nice. Even if you have to built a wall in the shower area for the plumbing, I think you could do something very cool there, perhaps adding some shelves on that wall for additional storage.

I would change the swing of the door though, so you don't open it up into a person standing at the vanity.

In terms of resale, if that is a consideration, I would think option A would be better as a separate tub and shower, I think, are much more desirable.

I'd pick plan B, but I am a shower and vanity person. That 36" vanity would drive me nuts. In plan B I could rip the Tub/Shower out and put in a big shower.

Plan A makes it look like you have tried to fit too much into a space that can't handle it and thus have a 36" vanity in the master bath.

I don't have a lot to add about which plan, just a couple things I thought of - I would hate that small vanity, even with only a single sink because I need more counter space. I now have a separate shower and tub in my downstairs main bathroom and I'm planning on taking out the shower and adding one to the tub. Think about how you'd enclose a tub/shower combo. I don't really like glass shower doors on a tub because it is too claustrophobic when bathing, so think about if you would mind that or a shower curtain on the combo. Also, your plumbing controls should be to the side, not in the back of the shower so you can turn them on without getting drenched before you get into the shower, or spray toward the opening. Hope some folks here have some brilliant solutions!

Thanks for all input! My husband likes the 2nd plan, as he is a shower person. I hate small vanity but I don't like enclosed bath, unless I could find an appealing design, which I could not find anywhere. Almost all magazines show separate bath/shower, or, for a small space like ours, suggest only a shower. :( Does anyone has some nice picture on tub/shower combo for inspiration?

For plan A, I am thinking: would it be fine if to build the shower in neo-angle shape, with 34x42"? And at position A (in plan A), build a 24" wall and install the shower plumbing on this wall. Then use glass door/wall on the other 2 sides. Then build a slightly bigger vanity (42") till the 24" shower wall.

And is our space for tub in plan A too small for deck? Anyone has opinion how many inches mininum for a deck?

Thanks!

Here are a few inspiration photos from Houzz. I think I could live with any of these baths!

Hi olychick -- Thank you for the pictures! They look very nice! I would think and discuss with contractors.

I don't think there's any way you're going to fit a tub with a deck on the wall with the door. 36" is not much space to work with (I know; we have the same problem!). How about putting a tub/shower combo where the toilet is (on the window wall), toilet where the shower is (with back on window wall), and a longer (but still one-sink) vanity where the tub is? You could have a storage unit where the vanity is (all references are to Plan A). Or you could put a shower in that corner, although it would be small.

My kids' bathroom is about the same size and it has a separate shower (smaller than 3x3) and tub with a pedestal sink. It's really claustrophobic, even though the tub is narrow (29", which I don't think you can even find anymore, at least with a decent length). When we remodel it I'm going to put in a tub/shower combo, even though I do prefer a dedicated tub (our master only has a shower, but I like a bath every so often). Our master bath has two sinks, and while it's kind of nice every few months when we want to brush our teeth at the same time, I definitely think one sink would fit better in your bathroom.
