Interior ideas

I just did an estimate for a wonderful couple who were looking to remodel 2 bathrooms. I think the bathrooms remodels are a good idea as the house is 40 years old. But what I suggested that cost a fraction of that, that I believe would dramatically improve and update the interior look, would be to replace the interior doors. They have old stained doors. I said lets try some 6 panel doors and paint everything white. They loved the idea. This will cost with labor under $150 per door.
