1Natural Stone Farmhouse Sink Installation Instructions
INSTRUCTIONS
Unpack and inspect the sink for any shipping 
damages and ensure that none of the required 
pieces are missing. If you find any damages, do 
not install. Contact Customer Service at 
1-866-855-2284. If you need assistance while 
installing your new farmhouse sink, call our 
Customer Service number.
Due to the manufacturing process, each sink will 
vary slightly dimensionally. Farmhouse sinks may 
require custom cabinetry. We recommend 
consulting an experienced cabinet maker for 
assistance. Providing the cabinet maker with the 
actual sink to be installed will ensure a custom fit.
Please use assistance when lifting the sink in 
order to avoid personal injury. 
We recommend consulting a professional if you 
are unfamiliar with installing kitchen fixtures and 
plumbing. Signature Hardware accepts no liability 
for any damages to the floor, walls, plumbing or 
personal injury during installation.

CRAFTSMANSHIP
Stone sinks are individual works of art, carved from a single block of 
stone. Each block of stone has its own characteristics including color 
variation, veining, minor pits, non-structural fracture lines and flecks of 
minerals such as copper, silver or gold. Your sink is a one-of-a-kind 
creation that you can cherish for years to come.
INSTALLATION
Because most stone is porous, it is important to take special care of 
your sink to protect against harmful substances.
Upon receiving your sink, seal with a product such as StoneTech Heavy 
Duty Sealer. To retain your sink’s natural shine,
reseal your sink once or twice a year.
When installing your sink, carefully use silicone to seal the drain and use 
extra caution to keep the silicone away from the exposed sink area. 
Oil-based sealers or plumber’s putty should never be used on your 
sink. These products will stain the stone if applied near the surface of 
the polished basin. If staining does occur, use a standard stone and tile 
stain remover. For more difficult stains, apply a poultice product from 
StoneTech directly to the stain.
