Minimum Residential Bathroom Size

Minimum Residential Bathroom Size

• #1

Hello,

I have a hallway and closet that I'm thinking of converting to a half bath. It's a little awkward and I'm not sure I can meet the 24 in. space in front of the shower.

What do you think?

Try using a by-fold type door or shower curtain!

What do you think?

I think your right, your measurement is at an angle and does not meet the IRC figure R307.1, like Rick sez "need to measure straight from the shower to the WC.

I mistakenly took the 2'0" as a shower door swing.

The shower department

access

is 22-inches (opening into shower?)

The

clearance in front of the shower

is 24-inches. See figure R307.1

Isn't this two different requirements?

Thanks all for your replies. I've drawn up new plans based on the feedback. Could you please take a look?

Where did the 24" code come from? What are the finished dimensions of the shower stall?

I'm using the 2016 California Residential Code and 2016 California Plumbing Code. As some members have noted the CPC seems to omit any shower clearance requirement:

My R307.1 sends me to the CPC. I can't find anything about it in the CPC.

tiger there is nothing in the CPC regarding this These are the closest sections

Although I don't imagine they would go less than the IRC. Usually they are stricter than the IRX: like requiring 24 inches in front of the toilet, instead of 21 in.

The shower dimensions are 32x32.

Why do you want the shower

I really need a second shower for the morning school/work rush..

1. Is this on the first or second floor?
2. Is corridor door existing? If not consider using a sliding barn door as I have done on a similar sized bathroom.
3. Can toilet location be swapped with the sink? If so then you could use a corner sink just as I just did in a similar sized space..

1. First floor.
2. Corridor door is not existing. Barn door is a good idea. But I'd prefer an inswing if possible. (I know, I'm asking too much.)
3. Good idea! I've drawn up a new plan (below). But I tried to fit in a standard 24x19 vanity.

The clear space in front of the toilet is 24 inches but not for the entire 30 inches. There is a corner overlapping the vanity. Would that matter?
Thanks again! You all are really helpful.

Please verify with your building department as the the minimum interior dimensions required for a shower. I thought CPC 408.6 requires a minimum finished interior of 1024 square inches, and capable of encompassing a 30 inch circle.
