The bathroom should be equipped with a bathtub, washbasin, toilet, and washing machine

If you have time, you can wash it again, but if you don't have time, you can just care. What's so uncomfortable about this?

First of all, you must determine the size of the above products, generally single bathtub specifications length 1700X width 750 shower room 1000X1000 toilet width 470 length 750 height 670 bathroom cabinet single basin generally length 800X width 600 Sometimes you have to look at the layout, the layout is good, the width and length need to be a little less, unless you can do a big bathroom.

It is okay to make a washbasin outside the bathroom door, which is the kind of isolation, and it is more convenient, but it may not be good to ask, and it is a basin in the past, which is not beautiful, and it will not be done under normal circumstances.

There is nothing inappropriate, many of them do this nowadays, there are benefits, at least to maintain the independence of the bathroom.

I don't know if the red cabinet matches the overall color of your bathroom, it is recommended to put the cabinet with the overall color, so that the overall feeling will be better. If the overall color is darker, a dark red cabinet is also a good choice.
