Oval design bathtub – can it be moved slightly due to dirt behind it?

haha. That was not meant as a joke at all, because the processes are now also available in a nice format:

I have another idea. Put a floor drain in the middle of the room, then you can simply spray everything out behind the bathtub with the shower.

This saves the drainage of the shower with good planning and also, with a slightly larger bathtub (at least 1.8 m), wiping up the overflow water when used by two people.

You should only put such a Schöner-Wohnen-Victim accessory in the spa palace if you also have the chambermaid who diligently wipes it down. On business, I often stay overnight in hotel rooms with such freestanding pieces, and some of my buddies have put something like that in their palaces. Unfortunately, no one has such a central drain, and accordingly, the tub is practically unusable because of the flooding that immediately requires calling the chambermaid. Of course, she could discreetly roll you into the adjacent room while she cleans the main bathroom. Seriously: if you absolutely want a freestanding tub, then buy it. But please keep it in appropriate conditions, i.e., in a bathroom the size of the corresponding Schöner-Wohnen article. However, after that, please neither move nor weigh it down.

I fully agree with the addendum. However, emptying the tub precedes spraying it out, and the drain choked quite badly on this surge. That would basically be adding insult to injury.

I wouldn’t have done it any nicer ... Mr. Kapellmeister, a drumroll!

You mean, when he pulls the plug, it comes out of the floor drain? I think with adequately sized ventilation or in the worst case a separate downpipe routing (to the washbasin side), it’s not a problem. The plumber should just calculate it...
