Generally speaking, tiles are for indoor use, while pavers are for outdoor use. The main difference between travertine tiles and pavers is their thickness. Tiles are around 1/2 inch thick, and pavers are 1 1/4 inches to 2 inches thick.

Pavers are more rugged and can handle different weather. The extra thickness on pavers also makes them ideal for high-traffic areas.

Outdoor kitchens get wet and are sometimes next to pools. To avoid accidents, go with a non-slip material like concrete, brick, or rubber. Avoid materials like ceramic and porcelain, as they are known to be quite slippery. Wood and composite flooring can be slippery if untreated, so make sure to stain or finish these materials.

Asphalt and tarmac are not the same thing. Traditional tarmac, short for tarmacadam, uses tar as a binder to hold crushed stone together. Asphalt uses bitumen—a byproduct of crude oil—to bind aggregate. Though tarmac was once a go-to for roads, asphalt has become the modern standard. And these days, most surfaces referred to as “tarmac” are actually asphalt. So, while the names may overlap, the key distinction lies in the binder—tar for tarmac and bitumen for asphalt.

The ideal distance between stepping stones depends on your design preference. A general rule is to place them about 24 inches apart from center to center to match an average person's stride. Another common approach is to leave about 6 inches of space between the edges of each stone; this can be adjusted to fit the path's total length without cutting pavers. If you plan to plant between the stones, leave at least 6 to 8 inches of space to give the plants room to grow.
