hope this layout helps

Trust me, 42 x 48 for a shower, is plenty fine. Every fixture/element needs clearance

Dhanashree, of the two layouts you drew, which would you prefer? Is it awkward to have the big shower right to the right of door when you walk in? And will it kill the light coming in from the window? Also, if the vanity is along the door wall, is it awkward to walk into the side of the vanity? Should I consider putting a pony wall up at the end of the vanity?

Jan, thank you for the sketch, I love it... but my wife is adamant on a 42x60 inch shower. I was also recommended by contractor to not use a half wall for shower.

Beth, thank you! awesome pictures and advice. We do have a vanity, tile, and lighting all picked out. we are not doing a tub. I would like to add a linen closet, my wife doesn't think it is necessary. I can't figure out how to work in a closet with the 72 inch vanity... if we moved down to a 60 inch I can see it. But, 72 inch vanity is already bought and in our garage! BTW, I looked at your bathroom and that is awesome. nice work!

It's right here. Next to the vanity. Twenty four inches wide, approximately.

Note. When you stand in a lowly tub shower, which you may be doing? You stand in 20 inches width. Baths are about inches. The contractor "didn't recommend a half wall. WHY? Glass on top of that knee wall gives you all the light from the window within the shower. It doesn't "leak".. Maybe have the brilliant contractor design your bath, as he apparently can not do, : )

You can leave the door and do as suggested above by another poster. Either can work as she posted. But a bath with no linen consideration is one I would try to AVOID. The bath is "adamant" about its INCHES. The inches are the dictators.

I can assure you a 42 x 48 shower is very generous in daily use. Having no place for supplies and towels and etc at hand is not fun in a master bath, Which is why you plan first, buy vanities and tile etc..........after. I assume you now have a vanity with two finished sides, and in almost any scenario ......you don't want or need two finished sides.

@ Teague. Reply to questions you asked

you won't feel awkward as still you are left with 4' space and if u have glass shower your eyes would run till the end feel like a large space.

your window is not block in any of my options so will be getting natural light don't worry about that.

if u see the second one vanity counter to your right then you should not have tall cabinets just as you enter. counter and a tall cabinet at corner still would do

pony wall not needed

and

Which one would i prefer is the first one as i would like to see vanity counter as soon as i enter even shower is not bad till i don't get to see a toilet in front any thing would do. but its up to you. i have save 2 image below for you to get a better understanding. i don't know your style but i have kept it simple.

option 1 - as you enter from door

option 2 - from the wall opposite window

Thanks Jan. I will talk to my wife about the different layout options with either a smaller vanity or smaller shower.

Don't shrink the vanity. She will NOT miss that 12 inces ( one direction only ) in the shower. Going to have to trust me on that : ) Sharing a vanity means at least 72 inches. Less is NOT good.

Chalk off any layout on the SUB FLOOR. The genius contactor can do it,

Dhanashree, thanks so much for the pictures. Thats exactly what I needed to see!
