2.Trial Fit
i.Check to be sure that the vanity base cabinet is level and properly secured to the wall. Buy Stones Online recommends using shims in areas where there is not a solid point of contact or where the top is not level on the cabinet

ii.Wipe cabinet frame with a damp cloth to remove dust particles

iii. Trial fit vanity top, back & side splashes to ensure correct size and fit. Use care when handling vanity top to prevent damage to stone or cabinet

ii.Clean dust and foreign particles from underside of granite vanity top

iii.Unpack under mount bowl (to be purchased separately) and place it next to granite vanity top

iv.Align under mount bowl on bottom of granite vanity top with pre-cut hole

ii.Use damp sponge to wipe away excess silicone caulk and smooth the finish line

iii.Install the faucet and the drain assembly according to the manufacturer’s instructions

iv.Wipe off the top of the vanity cabinet with a damp cloth to remove any dirt. Apply a generous (1/2”) bead of silicone around the top edges of the vanity cabinet

v.Carefully lower the top onto the vanity cabinet with a ½ inch extra on each side. In addition make sure that the shims stay in place

vi.Wipe away excess caulk and allow to dry according to the caulk’s manufacturer instructions

vii.Attach the drain pipe to the drain assembly. Attach the water supply lines to the faucet

5. Install Back & Side splashes

i.If back splash is to be installed, do so at this time. Test fit the back splash to determine proper fit, and which side will face out and which side will face the wall

ii.Wipe the bottom of the back splash and the top of the vanity with a damp cloth to remove any dust or dirt

iv.Place a 3/8-inch bead of clear silicone caulk on granite vanity top edge where back splash is to be located

v. Place unpolished edge of back splash on caulk and press gently against wall and down on to the granite vanity top. Move side to side to spread the adhesive evenly

vi.Bottom of the back splash should lay flat or be flush with the top of the granite vanity top

vii.Remove all excess caulk and clean with a soft cloth or sponge. Allow caulk to dry according to the manufacturer’s recommendations

viii. If side splashes are to be installed, follow steps (i-vii)

ix.Apply a thin bead of caulk around all of the joints, such as the one between the top of the back splash and the wall, the side splash and the wall, the vanity top and the back splash, and the vanity top and the side splash
a)Note: Walls may be uneven and create a slight gap between the wall and the back or end splash. Do not force or pressure the stone to straighten the wall. Fill gap with caulk
