Do you plan to stay in this home? Because how you all use the bathrooms now, will absolutely change as your kids get older. Particularly with a son and a daughter.
I would want 3.5 baths, but at the absolute very least I'd add a half bath, preferably a full. What do the other houses in your area have? Considering comparables for resale purposes is never a bad idea. You don't want to be the outlier. |
This is exactly what we have except our kids bed/bath is on the main floor and it's perfect. |
It won't cost much more to add a full bath rather than a half bath, so, might as well go for the full. |
This. We have 4 BR and 2.5 Baths. It is workable (but not perfect) only until the grandparents visit, and then we really wish we had a 3rd full bath (which lets grandparents share one and kids share a different one). |
If space is an issue, go for a 3/4 bath (shower only, no tub) in the addition. Be forewarned this will save a little space, but it will not significantly change the construction cost compared with a full bath. |
