IP,

Since you mentioned that it's a 5 bedroom home, with one of those bedrooms converted to a laundry, having "only" a 4 bedroom should not hurt marketablity. Personally I see benefit in a having a large laundry room. Others who look at the home would also be able to easily that if they needed a fifth bedroom they could convert the space. I would be more concerned with the "link" to the master bedroom. Would prefer that this laundry area have it's own access, so older children would be able to do their own laundry without having to gain access to the laundry room thru the master bedroom. Or if there is seperate access, that the link to the master be sealed, for privacy.

Your idea of putting washer and dryer in the master bathroom would be an issue for me as a potential homebuyer. When my children were in high school, they started having to do their own laundry.
