Black Beauty Granite Slab – Polished Kitchen Countertop in Nairobi
Black Beauty Granite – Polished Countertop Slabs in Nairobi
A deep black natural stone flecked with silver-grey and bronze crystals that sparkle under a mirror-polished finish. Hard-wearing, stain-resistant and timeless — the go-to choice for kitchen countertops, vanities, staircases and window sills across Nairobi and Kajiado.
Product Overview
Black Beauty granite is an igneous stone formed from slowly cooled molten magma, giving it a dense crystalline structure and outstanding durability. Its dark base with scattered grey and bronze crystals hides crumbs, water marks and everyday wear far better than light-coloured surfaces — ideal for busy family kitchens.
At Shabbiri Hardware Kenya, serving builders, fundis, kitchen fabricators and homeowners since 1990, we stock factory-polished Black Beauty slabs ready to be cut to your kitchen, vanity or staircase layout. Pair it with our cabinetry boards, edge banding, sinks, taps and construction chemicals for a complete one-stop solution.

How to Use & Install
Measure the area
Measure cabinet runs, walls and corners. Mark the sink, hob, taps and sockets, and allow a 20–30 mm front overhang.
Choose your slab in store
View the actual slabs at our branch and pick pieces with consistent tone for the whole job.
Prepare a level, rigid base
Cabinets must be solid and perfectly level. Add a board sub-top or battens on long spans so the stone is fully supported.
Cut and fabricate
A granite fabricator cuts the slab with a wet diamond blade, makes sink and hob cut-outs, and polishes the edges.
Handle with care
Carry slabs upright on edge, never flat, with at least two people. Support cut-out areas — they are the weakest points.
Fix in place
Apply stone adhesive, epoxy or neutral-cure silicone on the base, lower the top, check level and bond joints with black epoxy.
Seal joints
Run neutral-cure silicone along wall joints and around sinks, wiping off excess before it cures.
Seal the surface
Once dry, apply a penetrating granite sealer for extra stain protection. Re-seal about once a year in kitchens.

Frequently Asked Questions
Is Black Beauty granite good for kitchen countertops?
Yes. It is dense, has very low water absorption and resists scratches and heat — one of the most practical countertop materials for busy Kenyan kitchens.
Does Shabbiri Hardware cut and install granite?
We supply the slabs only, and can share contacts of independent fabricators who cut, edge-polish and fit the tops on site.
Does black granite need sealing?
It absorbs very little water, but a penetrating sealer after installation and roughly once a year adds protection against oil and stains.
Will every slab look exactly the same?
No. Granite is natural, so crystal size and pattern vary slightly — that is why we recommend choosing your slab in person.
Can it be used outdoors?
Yes. It is colour-stable and weather-resistant. Note that a polished face can be slippery on wet steps and floors.
