Hi,
What is the correct height for Wainscoting for 8 foot tall walls?

Is there any difference between buying name brand bathroom fixtures (i.e.
kohler bath and toilet) from a plumbing supply store vs. a Lowes, or Home Depot
Store? The prices at Lowes and/or Home Depot are a little lower for the same
model fixtures. Are the models truly not the same?

Thanks in advance,
Regards,
Donna
