Honestly , I would prefer a larger shower 3.5 x3 is tight... Can you sacrifice some closet or have an open toilet area?

Most of this bathroom is too small for comfort:

- You must have 30" in front of the toilet; you have about 20". If you can close the door, your knees will touch it.

- The shower will meet code ... barely. It won't be comfortable.

- Where'd all the space go? To the sinks! Two separate vanities require a good bit of space, and with space at a premium, I'd say you can't afford that empty foot of space between two vanities ... also, the two separate vanities will break up the space and make it look small (which it IS, but streamlining things will help). Note that although these vanities are extra-deep at 24", they'll have no drawer storage. My suggestion:

- The toilet now has the required clearance space in front. I put it behind a pony wall, which will provide a bit of privacy -- honestly, this is the space you can afford in this small space. You can make the pony wall hollow so you'll be able to store toilet paper in it and keep candles or a basket of toiletries on top of the pony wall.

- The vanity is about 48" wide and a standard 18-19" deep. It will comfortably hold one sink with drawer storage on each side. Again, this is what you can afford in this space.

- The closet is bigger now and the door is bumped to the left ... meaning it can have storage on three sides, and you'll have a 36" walkway down the middle ... not luxurious, but comfortable. I'd go with a pocket door on the closet to avoid the door swing.

Final thought: Look at how much space is not being used /is only empty walking space in each of these plans ... the more streamlined plan allots more space to your functional items. In my plan you have an extra 12" of space to stand in at the sink, and you're not wasting extra space on both sides of the shower /between sinks.

Do you NEED a walk-in closet? If you were willing to do a standard closet, you could run it along the top, 10ft wall, and then see if that allows you more space as the bathroom?

Taking backyardfeast's suggestion for a standard closet along the top wall (but, I do see there in a window there), here's my idea. With the reach in closet along the top wall, you would create a hall with the closet on one side and the bathroom on the other. You could enter the bathroom at the end of the hall with a pocket door. Entering the bathroom, the vanity would be on your right and the shower and toilet on your left.

I love Mrs Pete's floorplan, though I'm not sure there's room for a pocket door in the wall between the shower & the closet, the way she has it drawn. I'm not a fan of two small vanities - no room to put toiletries, hair dryers, etc., while getting ready, nor to display something pretty on the countertop, for personality. We downsized from a master bath with a separate water closet (toilet room), to one "out in the open" in our new bathroom, and frankly, we're just never in there at the same time, so it became a moot point.

MrsPete I appreciate your feedback and suggestions. I like your layout but I dont think it will allow us to comfortably use bathroom and closet at the same time especially with the closet being across from the toilet.

The toilet room in my layout is 3' by 5' which will give 32" in front of the toilet. The dimensions in my layout were not exact. The vanities would also only be 20" deep.

I also have room to increase the size of the shower if needed.

I would rather not cover up the window with a closet. I like being able to see into the backyard.

Guideline 21: Toilet Compartment

If both a bidet and toilet or toilet and wall urinal are built into one compartment, the arrangement of fixtures within the compartment must conform to Guideline 20. This usually results in a compartment between 62” and 65” wide, depending on the width of the fixtures selected.Recommendation: The size for a separate toilet compartment should be at least 36" by 66" with a swing-out or pocket door.

Building Code Requirement: The minimum size for a separate toilet compartment is 30" by 60". (IPC 405.3.1)
Comments:

1. The Guideline implies that a toilet compartment must have a door. Actually more toilet compartments are built without doors than with.
2. An inswing door can be used if the width of the door is added to the depth of the compartment. For example, if the compartment has a 24" door, add 24" to the 66" length of the compartment. The new 90" depth accommodates the inswing of the door.
3. This guideline also applies to a bidet compartment.
4. If both a bidet and toilet or toilet and wall urinal are built into one compartment, the arrangement of fixtures within the compartment must conform to Guideline 20. This usually results in a minimum compartment width of between 62" and 65", depending on the width of the fixtures selected.
5. If the compartment needs to be wheelchair accessible, the minimum width is 60".

Do
you NEED a walk-in closet?

This makes sense.

You're probably right about this.

I would rather not cover up the window with a closet. I like being able to see into the backyard.

The window isn't covered up ... that's a pony wall, not a toilet closet ... you'd have the window.

None of these are big enough for comfort -- and I'm a small person! This is essentially relegating yourself to using something the size of the public bathrooms at the mall. Seriously, drop a measuring tape into your purse and measure stalls the next time you're out somewhere -- I'm sure you don't like using these minimal stalls. Difficult to clean too.

I have a similar size space to house the master bath and additional clothes storage. We ended up doing two well organized reach in wardrobes and choose a spacious bathroom and shower room over a walk in closet and separate WC and am so happy I did!

everyone's priorities are different. But you are going to have to chose priorities for this size area is not conducive to having it all. Either large closet and tiny shower and a closed, not to even minimium recommended sized toilet room or reach in closets, nice size shower and a pony wall WC. If resale is not a concern do as you will but what you have planned will not be desirable to more than half the population I feel.

This is nicely said.

BSSharpe, here's an idea: Put these items in order of importance ... that is, the one that you value most highly, move it to the top of the list, move the least important to the bottom of the list. Now, are you allotting space in accordance to what matters most?

- Closet

- Toilet

- Sink

- Shower
