lol! I wish. Just curious to get other architects' opinions. I actually used to work in Japan and they had lots of shared bathrooms due to lack of space and cultural leanings (they really emphasized the bathtub location). But working in the US, complete opposite, they really love their own bathroom spaces, not even a separate toilet closet.

Is it really a bathroom if there is no bath?

Shitter room.

I visited Villa Savoie earlier this year and it was... a strange setup. Toilets were in their own tiny rooms, complete with door handles (but no way to wash your hands?). Then the bidets were basically exposed in the washrooms / bedrooms, without a door separating anything. As much as you can tell that hygiene played a huge role in the design, it's mostly figurative hygiene, not the kind that deals with bacteria and viruses, apparently. It felt very, very odd.

The WC absolutely has to include a place to wash your hands!

That’s what the tank if for Donna. Very few people know of this life hack. On that note, a friend of mine lived in Lyon, France, and their toilet was in a tiny closet across the hall from a large bathroom. Sure, plenty of space in the other room for a throne and there was no sink with the toilet, but who’s going to argue with the French? The place also had orange carpet on the walls.

paired showers for kids? seems more adult... or is it just two showers for a single?

yes, it was a weird request, didn't dig further.

Good effort, anyway. ;-)

Also note, related to this, that standard American cultural practice is for doors to always swing IN to the more private space from the less private space. The rest of the world doesn't really do that (e.g. in Europe and many parts of Asia, front entry doors swing out, while in the USA they always swing in). That has a significant effect on bathroom layouts for residences in the US.

For us, an en suite for every sleeping room is the goal when space and budget permit. Some additional spaces like a home office or game room may also have their own adjacent baths with a w/c and sink. Very few people in the US will say "my house has too many bathrooms".

We have done a couple of primary bedroom suites with His and Hers bathrooms, make up vanity and soaking tub, like this one

We also have individual laundry rooms in addition to ensuite washrooms in most bedrooms.

You guys are designing for a wealthier clientele than I am. Most of my projects are under 2400 sf; a large house for me is 3200 sf, with construction costs around $400-500/sf. We can't afford the space or cost of all those extraneous bathrooms and bathtubs that don't get used.

WG, that's true, we are at 1000-1200/sq.ft. and over 5500 sq ft often. Just got a call from a client cancelling today's meeting because he couldn't land his plane with the weather.

Yeah. I should have qualified that. Our typical homes range from 3600 to 4500 sq. ft. But we build them all the way up to around 8000-9000 sq. ft.

Wood Guy - your budget for a single family residence is often greater than the budget for my commercial work.

Well bless your heart.

Care to show us some of your drafting so we can learn the good way? 

Sorry - I can't compromise my clients' privacy; but it doesn't take a lot to determine that the above image shows a snip from what appears to be a construction document plan with too much information on it that is both a disaster in terms of graphics and organization / hierarchy of content. Looks like someone sitting in their basement banging out a drawing for some exorbitantly low fee who took no pride in the work they do.

You could post up a 'snip' of a drawing and show us how it's supposed to be done without compromising your clients privacy.

Try and behave like an adult.

Here's an example, snipped so it's anonymized.

Not sure what the yelling is about... but this is the most info I'll put in a drawing.  Screen shot for in-progress washroom plan.

my take on a washroom layout

Much better!

Now this is helpful and productive!
