I need information about how to deal with the doorway from oneroom to another when the floor levels are about 1/2 - 1 inch different in heights. This is between my kitchen and bathroom, so an indoor issue. Is there a doorsill that can compensate for this change? Like a slanted one? I would prefer wood... I also don't really want to redo the floor in the bathroom as it is fairly new (its the 'low' floor)..the kitchen can't be reduced...to costly.
