130 m² bungalow for 2 people

If you don't have many overnight guests per year, I would place the guest/office room instead of the bathroom, move the bathroom to the current utility room, and the utility room to where the guest/office room is now. Then you can also properly hang laundry there.

The second Du-WC is for guests or elderly parents in need of care.

Oh man, the information that the questionnaire could clarify is missing again. I would use the long corridor for a 3-meter wardrobe and cleaning closet. On the subject of needing care and 4 sqm, I won't say anything more because it's too unrealistic.

Switching the rooms would mean having the HTR in the southwest and the study in the north, but the study is used as such too often for that. I have tried to change the hallway and kitchen area... however, I am still not really convinced myself.

Never without furniture in scale

Your question was specifically about the bathroom. I wouldn’t like the shower right next to the door. If you can still change the windows and depending on what kind of shower you want, I would place it more towards the outer wall. A shower attached to the bathtub doesn’t appeal to me. Basically, I really like the floor plan or the variants from , those look really great. I wouldn’t mind the access to the utility room from the bathroom compared to the gain on the other side; depending on user behavior, that can be an advantage. You could divide the room in the middle and make the technical room accessible from outside. In any case, I would eliminate that long corridor to the guest bathroom, maybe make it bigger and go from there into the utility room. You are two people, so it’s all manageable. That would make the dining/kitchen area much more spacious and nicer. There, I might anyway go for two rows or one row and an island opposite with a counter. Maybe that will also be enough for 1-2 sqm of pantry; that’s all you need. I like the current bedroom windows, I only like corner windows if they are really large. It looks good as it is, and with the solution from , you also have space in the dining room. Folding doors are stylish and if you have space for them, certainly an idea. Generally, I prefer a “normal” door rather than a sliding door. Maybe a door would be an option and the second leaf foldable 180 degrees if needed; I find that quite practical.

Building on the proposed ideas, I have created a version with access to the HTR through both bathrooms, in order to see the effect on the bathrooms in one image. One consideration is/was to have only a large shower in the main bathroom and to place the bathtub in the guest bathroom. For this, the main bathroom with 12.5 m² would be "somewhat" oversized, and the secondary bathroom currently does not seem to be sufficient for a 180/80.

The entrance and hallway are shifted to the south, the kitchen about 50 cm to the west. Around the table, there is approximately 90 cm of space with chairs placed as shown. To brighten up the kitchen, a window in the hallway could help; a simple glass pane should suffice. I find a cooking island very appealing, and the kitchen planner might have a solution for the pantry.
