It would be quite the ordeal to do it at this point. We basically left the drywall 6" off the floor and then when the floor was installed we put the 6" piece in and taped everything. If you were to do it now you would have to cut the drywall and install the 6" piece. You would lose the tape Join so there would be a lot more mud involved. To be honest it looks amazing on the pics but the practicality behind it isn't that great. You end up hitting it with your vacuum and denting the drywall.

Thank you never thought of the drywall getting damaged. Aluminum might fix that but likely an expensive option. Thanks anyway!!

Hi Dena,. Another option would be to use standard flat stock Mdf base. Much more economical than metal. Instead of the 6" piece of drywall use a 6" base. They sell a channel to make the gap between the two materials look finished.

hope this helps
