I see a possible few problems.
1) To stand in front of the right hand sink it looks like the corner of the tub frame will it be in the way?
2) Also, does the right hand vanity have a door or draws on the very far right. A door it will bang into the tub frame and may not open all the way.
3) If there are draws, will they be able to be opened enough?
4) Where is the door for the shower? It should be facing the vanity.
Been away for a bit, actually in sunny florida..lol..need to get back focused.
1,2,& 3 I'm aware of and may end up going with a 6'. And for right now I have the shower door (slider), facing the toilet. ? - why should it be facing the vanity? Tks...
