Do you have the dimensions of the room? Does the 89 sq ft include the shower and toilet area? Where is the entrance door?
Thanks.

It does seem a bit crowded, with the angle of the tub. If it was directly across one side of the wall, that could potentially save some space.

Umm, how do you get into the bathroom? I don't see a door! But yes, it looks crowded to me. It especially looks tight trying to get into the shower and possibly the point where the tub an sink are closest.

You must enter the bath from the top of the diagram which I'm assuming is the master bedroom. I don't necessarily think it's too crowded but we do need the dimensions. If you have a double sink at the vanity and your husband spends less time in front of the mirror/uses fewer toiletry products, make him take the "squishy" side closer to the tub. :-)
