Hello. We have been living in the house since June 1st. Since the bathroom upstairs was only completed about 4 weeks ago, we have been using the toilet there regularly only since then. For about 2 weeks, we have occasionally noticed a gurgling noise in the upstairs toilet. This means that so much water flows out of the toilet that the seal with the drain no longer closes completely, causing the noise. This happens only briefly because then so much water drains out that the toilet is almost empty. This does not occur in the downstairs toilet, although in my opinion more water could remain in the bowl there as well.
Yesterday, we experienced the following issue: the water in both the upstairs and downstairs toilets drained somewhat slowly. After flushing, water pooled in the bowl and then drained away, but with a slight delay. It took about 3 seconds for the water to disappear. Since then, a gurgling noise can also be heard from the downstairs shower when flushing. Immediately after showering, air bubbles were visible coming from the drain there. The water also drained poorly in the shower yesterday. I have just cleaned the shower thoroughly. Result: the water drains perfectly, but the gurgling noise when flushing continues to be audible.
What could be causing this problem?

I'm happy for you that the issue has been resolved after all. The problem, of course, could be that a poorly planned wastewater pipe from the guest bathroom keeps getting clogged. You can’t really ask every guest to only use the toilet in a certain way.
I would definitely take a closer look to see if there is a bottleneck somewhere. In theory, you can check the plumbing plans for this—for example, a bend or the supply line directly behind the downpipe or something similar.
