For bathrooms, the design team should consider slip requirements, joints, edge details, substrate preparation and cleaning conditions in addition to the visual finish.
Choose by real project conditions
Use full-size samples and approved technical data rather than judging only from a small screen image. For project decisions, confirm dimensions, thickness, finish, fabrication, installation and stock with the ALTARA team.
Why visit the Jakarta gallery?
Large-format stone surfaces are highly visual materials. Seeing the actual slab helps buyers compare colour, veining, reflectivity and scale more accurately.
Frequently Asked Questions
Can sintered stone be used on bathroom walls?
Yes. The surface is non-porous with water absorption below 0.2 percent and stain resistance grade 5, which suits wet areas. For wall cladding the specified thickness is 6 mm, while 9 mm is used for general interior surfaces.
What should be considered for wet-area installation?
Three things matter: a flat, waterproof substrate, sealed joints at corners and penetrations, and slip resistance for floors. A polished Bright finish is normally chosen for walls, while a Matte finish is the safer starting point for wet floors. Confirm the project requirement with the technical team.
Can I compare light and dark surfaces in the showroom?
Yes. Full-size slabs are displayed at the Jakarta gallery in Kapuk, Jakarta Barat, so light and dark surfaces can be compared on the same lighting conditions instead of from screen images.
Ketebalan berapa untuk kamar mandi?
9 mm atau 12 mm untuk dinding dan lantai; 6 mm biasanya untuk panel dekoratif.
Apakah perlu lapisan anti air tambahan?
Ya. Lapisan kedap air di bawah material tetap diperlukan; sifat tidak berpori pada permukaan tidak menggantikan waterproofing.
Bagaimana merawat nat dan sambungan?
Bersihkan secara berkala dan gunakan sealant yang sesuai; sambungan adalah titik yang paling perlu diperiksa.

Area basah: yang menentukan bukan hanya material
Kamar mandi menggabungkan air, sabun dan pembersih. Permukaan sintered stone tidak berpori dengan penyerapan air di bawah 0,2 persen, sehingga cairan tidak meresap dan noda lebih mudah dibersihkan.
Namun kebocoran pada area basah umumnya berasal dari sambungan dan detail, bukan dari material. Lapisan kedap air, kemiringan lantai, dan jenis sealant di sudut perlu ditetapkan pelaksana sebelum pemasangan. Ketebalan 9 mm atau 12 mm paling sering dipakai pada dinding dan lantai kamar mandi.
