Shower completed: but water is standing in the drain

Hello everyone,

The building inspection was in December. Our daughter has now removed the drain/plug from our shower, which has never been used for showering because the shower walls are still missing. I was very surprised: There is water inside. It is the same in the guest bathroom. Is that supposed to be like that? I would have thought that the water in the shower should always drain?! It is only the drain. The shower tray is dry. I would be very happy to receive an answer.

Best regards!

If there were no water under the cover, it would stink. The siphon is virtually integrated into the drain.

Ah, great, thank you very much!
