dp, I thank you very much for your comments, and I'm right with you. If I was in a $300k house, I'd go with higher quality doors. Unfortunately, the market value on my house is right at $120k and I'm not going to put $100 doors all through the house.
The house (1/2 duplex, actually) was built in 1978...on a concrete slab in the state of Kansas where winters are cold and humidity is HIGH. It is 1500 sq. ft., 3 bdrm, 3 bathroom, large kitchen, living room, and utility room.
All three bathroom sinks were made of PLASTIC. I've replaced one of them, and the bathroom vanity downstairs I had to demolish due to frozen/broken water supply pipe last January. I need to have the entire vanity replaced and this is going to be tricky because of the fact that the water supply pipes for the sink come out of the concrete slab to the FAR RIGHT of center, and then run horizontally about 3 inches above the concrete, THEN there is an elbow running them upwards. If they came out of the wall, fine, I could replace the vanity as MOST don't have backs. This is a job I'll tackle another time.
But you get the picture. I have a half duplex that was built with crap; the six panel woodgrain hollow doors are a huge upgrade. I don't plan to be here the rest of my life....
Thanks, really, for your comments, I agree wholeheartedly, but can't put that kind of money into a place that will never sell at a price to recoup that kind of improvement.
