The most forgiving and widely available. Porcelain (fired at higher temperature, less porous) is the better choice for outdoor and wet areas. Ceramic is fine for interior walls and dry indoor floors. For outdoor use: always specify minimum R9 or R10 slip resistance. Many showroom tiles look beautiful but are rated for dry indoor use only.
Volcanic basalt — dark grey, dense, naturally anti-slip, extremely common in Bali. Right choice for outdoor pool decks, garden paths and terrace areas. Resistant to rain, sun and moss when properly sealed. Must be sealed annually.
Softer, more porous than andesite, warmer look. Both must be sealed before use and regularly maintained. Not ideal for outdoor use in Bali unless you are committed to maintenance — they absorb water and stain easily.
Looks stunning but requires the most maintenance. Scratches, stains and etches from acids. Fine for feature walls and decorative applications. For bathroom floors: use honed (matte) marble, not polished — polished marble becomes dangerously slippery when wet.
Any tile going outside or in a wet area needs: outdoor-rated adhesive, slip resistance rating for wet conditions, and proper waterproofing beneath it. The tile itself is often less important than whether those three things were done correctly.
The single most common mistake we see in Bali is choosing a tile because it looked good under showroom lighting, then installing it somewhere it was never rated for. A beautiful matte porcelain meant for a dry living room ends up on an exposed pool deck, where it has no anti-slip rating and no UV stability. Within a season it is slippery when wet and the colour has shifted. Before you fall for a tile, ask one question: what is its slip rating and is it rated for exterior use? In Bali, that matters more than the pattern.
For living rooms, bedrooms and other dry indoor spaces you have the most freedom. Ceramic and porcelain both work, polished or matte, and softer natural stones like travertine and limestone are fine here provided they are sealed. This is the one place marble truly belongs in a Bali home — as a feature floor or wall away from constant water.
Slip resistance becomes non-negotiable. Use honed (matte) finishes, never polished, on any floor that gets wet, and specify a tile rated for wet underfoot use. Porcelain is the safe default. Whatever the tile, the waterproofing membrane beneath it matters more than the tile choice — a stunning tile over no membrane still fails.
Whatever natural stone you choose, factor in sealing — not just once, but on a schedule. Andesite, travertine, limestone and terracotta all absorb water, and in Bali's climate an unsealed surface stains and grows algae fast. A penetrating sealer applied on install and re-applied roughly once a year keeps stone looking right and shedding water. Porcelain and glazed ceramic do not need this, which is part of why they are the low-maintenance default for owners who do not want ongoing upkeep.
