Custom Natural Stone Window Sills in Kyiv
We fabricate interior window sills from marble, granite, quartzite, travertine and quartz composite to the measured window opening. Depth, projection, edge profile, junctions and installation are coordinated as one system.

REAL PROJECTS
RoyalStone window sills in completed interiors
Only published projects with confirmed imagery, material and delivered scope are shown.
MATERIALS
Stone is selected for light, interior character and use
We consider daylight, frame colour, opening depth, moisture, radiator position and the desired maintenance level.
Marble
Expressive veining and a broad palette for refined residential interiors.
Requires suitable protection from acids, pigments and prolonged moisture.→Granite
Durable natural stone for active use, deep sills and areas with plants.
A practical choice when resistance and straightforward care matter.→Quartzite
Premium natural movement and high strength for statement sills and wide openings.
Vein layout is approved on the selected slab before cutting.→Travertine
Warm natural texture for calm, tactile and architectural interiors.
Pore filling and finish are selected for the specific project.→Quartz composite
Engineered material with consistent colour for contemporary interiors and repeated sill sets.
Not natural stone; brand, collection and technical limits are confirmed separately.→MEASURED GEOMETRY AND JUNCTIONS
The sill is designed as part of the complete window detail
We record opening geometry, frame position, reveals, substrate, radiator, curtains and installation access. Visible faces and joints are approved before production.
Depth and projection
Depth from the frame, side returns and the safe projection over the wall or radiator are defined.
Thickness and edge profile
Nominal thickness, built-up edge, bevel, radius, straight or shaped profile are coordinated.
Opening geometry
We check non-parallel walls, angles, substrate irregularities and whether a template is required.
Frame and reveal junctions
Installation gaps, sealing and transitions to plaster, timber, tile or panels are planned.
Radiator and convection
The intended warm-air movement is preserved; depth and ventilation details are resolved on site.
Substrate and installation
Rigidity, level, fixing method, access, interior protection and final fit are verified.
ESTIMATE
What determines the cost of a stone window sill
The estimate follows the measured length, depth, number of pieces, selected material, edge profile, cut-outs, delivery and installation conditions.
Material and slab yield
Slab value, blank format, pattern direction and the number of parts determine material use.
Dimensions and geometry
Length, depth, returns, radii, angles, templates and irregular openings affect labour.
Edge and finishing
Built-up edges, bevels, radii, shaped profiles, polished ends and cut-outs are itemised.
Delivery and installation
Floor, lifting, piece length, window access, substrate readiness and visits form part of the proposal.

How RoyalStone window sills are delivered
Consultation
We receive opening photos, approximate dimensions, window count and material or edge preferences.
Site survey
Opening geometry, frame, reveals, substrate, radiator, projection and access are checked.
Stone selection
Available slabs or collections are reviewed and tone, pattern and finish are approved.
Drawing and layout
Dimensions, profiles, joints, side returns and pattern direction are fixed for production.
Fabrication
Pieces are cut, edges and ends finished, built-up details completed and geometry checked.
Delivery and installation
The interior is protected, pieces installed, junctions sealed and final fit verified.
SITE READINESS
What should be ready before final measurement
Final measurement is taken when the window position and surrounding construction decisions will no longer change.
Window frame installed
The frame must be permanently fixed, level and not scheduled for further movement.
Reveal finish defined
The thickness of plaster, panels, tile or other finish around the sill must be known.
Substrate accessible
The sill base should be open for level, rigidity and fixing-method checks.
Radiator and grilles defined
Radiator, convection grilles, curtains and nearby elements are recorded.
Windows counted and labelled
For multiple sills, a clear room plan and opening identification are prepared.
Delivery access confirmed
Route, floor, lift, stairs, floor protection and safe handling of long pieces are checked.
KYIV AND KYIV REGION
We survey and install window sills on site
We work in apartments, houses, offices, hotels and commercial interiors across Kyiv and the region. A preliminary estimate can be prepared remotely from photos, opening count and approximate sizes.

FREQUENT QUESTIONS
What to know before ordering stone window sills
How much does a natural-stone window sill cost?
The final amount follows dimensions, number of pieces, material, edge profile, delivery and installation conditions.
Which stone is best for a window sill?
Granite or quartzite are often selected for practicality; marble or travertine for a more expressive interior. Moisture, plants and maintenance expectations matter.
When should the final survey be taken?
After the frame is permanently installed and the reveal thickness, radiator position and substrate construction are known.
How far can the sill project?
Projection depends on thickness, length, support, radiator location and load. The safe solution is determined from the actual detail.
Can the sill have a thick built-up edge?
Yes. Visual thickness is often created with a laminated edge; the joint, pattern direction and profile are approved before fabrication.
Can plants stand on a stone sill?
Yes, although trays and prompt removal of water and soil pigments are recommended, especially for marble and travertine.
Does RoyalStone install the sills?
Yes. We coordinate the substrate, deliver, fit, fix and seal the junctions.
How long does fabrication take?
Timing depends on material availability, opening count, profile complexity and installation schedule, and is fixed after drawings are approved.
Do you work outside Kyiv?
Yes. Survey, delivery and installation are available throughout Kyiv and the Kyiv region.
