Sorry to hear that. Why do you hate them? Are they the Bellawood matte finished from LL? We are considering installing that same material.

Prefinished could mean solid or engineered...the type of finish (oil/hardwax; polyurethane; urethane; Aluminum Oxide; etc) will tell us HOW to change them.

What is upsetting you? The colour, the species or the gloss level?

Technically it is possible to change out the colour and the gloss level so long as you have a solid hardwood or an engineered hardwood with enough "meat" on them to have them fully sanded and refinished. Please be aware this has some heavy costs involved.

If you like the species and the colour, it is possible to change the gloss level...if the manufacturer makes a "polish". BE WARNED that working with a polish to change the gloss level is a LIFE LONG PRISON SENTENCE. Once you start with a polish you must ALWAYS POLISH. There is no going back. It is like turning to the "Dark Side".

Please tell us more about your floors, what it is you hate about them, etc. Manufacturer and details (engineered, solid, finish on top) are needed to know what are the best options for your situation.

As an aside, please turn of your caps lock...it always makes for difficult reading when everything is in caps...Thanks.
