@SQUEEKY2: That means either the guests (who are downstairs) will have to go upstairs to use the bathroom, which means they’re looking at the bedrooms when they go to the bathroom. If the bathroom is downstairs, people who are in bed and need to go to the bathroom will have to go downstairs. It makes no sense to have it that way. it would be hard enough if it were a ranch house.
@Dutchess_lll: En suite helps with resale value as it means privacy for the people in the bedroom with the en suite. Come out of the shower, you go right into the bedroom without having to put clothes on because you’re in the hallway. If you’re half dressed in the bedroom and want to go to the bathroom, you don’t have to worry about putting on clothes to go in the hallway to the bathroom.
It will probably be so much cheaper if the friend puts the bathroom in during construction, rather than deal with it after. Plus with the mess, if the house is being built now, better to do it now than to cause disruption when they’re living in the house and everyone is busy with their lives.
I just redid my one bathroom a few months ago, and it means we had to stay in a hotel for a week. It was kind of fun but it meant over 700 dollars just for the hotel for the week, which is added on to the cost of the bathroom.
