Yeah, you should simply be able to read properly and not argue with false facts..
Says the one for whom 61 cm is a bit more than 74 cm and about the same as 168 cm. So the sketch is of little use for realistically imagining the situation.
And last but not least, this is my personal opinion: the tub just looks cramped and lost in that small bathroom. Like something attempted but not achieved. A freestanding tub needs space. The word "freestanding" already implies that. Or does the catalog say "tub model that should be squeezed into a corner"? To work, it really has to stand free. Free, without being placed directly against walls. But that is actually a matter of taste.
Yes, but the intended everyday use of a designer bathtub as a laundry collector seems almost perversely borderline to me. Pushing a freestanding tub into a storage corner doesn’t work, it stifles it (my opinion). Besides, the original poster makes the significant error of thought that the tub before emptying is still literally heavy and that when shifting it, forces will act on it under which the rollers will have to give up. Apart from that, this construction is not suitable to carry and transfer the weight of the full tub (opinion of physics).
