Planning of the main bathroom for a single-family house

Hello everyone,

we will soon be building a single-family house (with general contractor) and are slowly starting to work on the planning. At the moment, we are focusing intensively on the main bathroom. Since we don’t have the ultimate idea yet, we wanted to ask here in the forum if anyone can help us.

Here are the floor plans for the ground floor and the attic.

Ground floor:


Attic:


The knee wall in the attic is 90 cm, the maximum room height at the gable is 3.50 m.

We don’t particularly like the following things about the bathroom layout in the attic:

- The shower is quite small for the main bathroom (80 x 80 cm)
- The bathtub is also fairly small (I am almost 1.90 m tall)
- The toilet is directly “in sight” when entering the bathroom
- Due to the alcove (storage room), the bathroom overall is quite small. Since we will have a fairly large basement, we don’t need the storage room.

To mitigate these disadvantages, I made 2 drafts, both of which have certain drawbacks. In both versions, by the way, I hinged the door outwards because the hallway is no longer a “through hallway” after removing the storage room.

Version 1:


The disadvantage here is that the space by the window could become tight due to the shower (100 x 100 cm). The window might possibly be moved closer to the bathtub. However, this could entail costs for an additional building permit.

Version 2:


This version is basically identical to Version 1, except that the double sink and the shower have swapped places. The problem here could be that the toilet ends up too far under the sloping roof (as I said, I am almost 1.90 m tall).

What do you think of the two planning versions? Does anyone have another idea that I haven’t considered yet?

Thanks a lot in advance for your help!

Best regards,
Seb.

To shift one or two windows by a few centimeters, no new building permit is needed.

How should the shower enclosure be designed? Wall or glass?

Where is the 2-meter line? That is usually decisive!!!

For your two alternatives, enlarging the room is not necessary - you have squeezed everything to the door ;)

Edit: I found the line [emoji15]

Yes, if it is only a few centimeters, no building permit should be necessary.

The shower enclosure should be made of glass. This way, in variant 1, there would be as much natural light as possible at the double washbasin.

If a completely different idea would allow a wall as a partition, we could also live with that.

I roughly sketched this out for myself... I once had such a bathroom, the dimensions of 2.50 x 2.20 were common in the 70s/80s. Whether a person over 190 cm squeezed into a tub, I doubt that ;) That’s probably why the hype in the 90s was to generally do without a tub, at least in renovations. For how many people is the bathroom supposed to be? Nowadays, I consider it a planning mistake for more than 3. The extension hardly brings anything, mainly just to pull the tub into the slant. What about the hallway? Possibly allocate some of it to the bathroom?

I would leave out the bathtub. With 6.5sqm, the main bathroom was planned way too small if you want to fit "everything" from the large shower to the double washbasin there. The additional space gained by removing the walk-through area doesn't help much in the bathroom due to the lack of height. Your drawing also still misses the pre-wall installation.

Thank you for your feedback.

For your two alternatives, enlarging the room is not necessary - you have squeezed everything to the door anyway ;)

Where else should I place it then? There is definitely too little space for a partition wall.

I roughly sketched it out...

Did you forget to attach the sketch or did I misunderstand you?

The extension hardly helps, only really to pull the tub into the slope. What about the hallway? Maybe steal some space from it for the bathroom?

I had already considered that before. However, you only gain space there under the sloped ceiling. How would you arrange the bathroom if the hallway were sacrificed?
