Bathroom accessible from 2 sides - What kind of locking system?

We also have two doors in the regular bathroom. You simply lock and unlock both. It takes one second longer, not worth mentioning. I wouldn't want a technical solution there.

I also wanted to suggest the pragmatism of . How much money do you want to invest to prevent an inattentive person from being exposed to the embarrassment of being disturbed while using the toilet? And then you invest thousands and jump up from the pool lounge chair because a loud scream from a person exposed to a situation as described above shakes the neighborhood. No technology could prevent forgetting to lock the perfect double-door system.

I like the idea of the bathroom accessible from the outside. Especially when children use the pool, they often need to go to the toilet and are not very careful about drying off. I would also install a patio door that you can simply open when it's pool time. It will happen that some people or children forget to unlock the inner door again. To avoid this, you could also just plan a small lockable toilet in the bathroom. Something like a T-shaped or L-shaped solution with a door in front. Then you only lock the toilet when you need to.

I don’t think the idea of accessing the terrace directly from the ground floor bathroom is crazy at all, as was written above. But I do think you’re overcomplicating it. Think about separate pool houses that are also used for changing. In that respect, I agree with on the optimal planning: plan a terrace door. If you plan a pool day, you go through the bathroom, change, and use this terrace door. If you want to use the toilet or take a shower, you go back into the house through this door. After an extensive pool day, you close the door from the inside. However, I would also plan the bathroom or the ground floor afterward – I find the sketch a bit meaningless now. Since you probably aren’t a six-person family that is embarrassed by each other going to the toilet, there doesn’t have to be a locking system. There can be arrangements.

Thank God at least 2 people don’t find the idea so reprehensible :)... If it should come to that, I would probably actually lock both doors manually. It’s a pity that there is no possibility.

I also think the idea is good, but I would not invest in technology to prevent both doors from opening. If the pool is being used outside, the interior access is simply locked. If nothing is going on outside, the terrace door to the outside is just closed. Quite simple.
