Would re-doing the stairs and handrail be prohibitively expensive?

Q: I have oak parquet in living/dining and kitchen, and oak stair treads and handrail. Everything is stained dark ebony. I want to refinish, and would like to have a lighter, taupe/grey, high-gloss look.

Questions – (1) Is this possible?

(2) Would re-doing the stairs and handrail be prohibitively expensive- enough to make me consider keeping the ebony?

A: One thing that needs to be kept in mind with stains is that it is about impossible to remove all trace of stain from heavy grain. So, if you go from ebony to a pastel like taupe, you will still have some trace in the heavy grain and it will show. It is impossible to predict how significant that would be. It also works the other way when going from, say a white stain to ebony.

Your case would be even more expensive because a non yellowing water borne finish would have to be used with a pastel colour. They are always more costly. About a third more.
