The best trowel for penny tile is a 3/16-inch-by-5/32-inch V-notch trowel. Because of the small size of the penny tile, you want a trowel with small notches that can lay a thin layer of mortar on the surface you’re tiling. If the notches are too wide, you risk applying too thick of a layer of mortar, and it can squeeze out between the penny tiles.

To make a bathroom look bigger, choose light-colored, medium- to large-format tiles. Light colors such as white, cream, or light gray make a space feel more open, while dark colors, busy patterns, and small tiles can make a bathroom feel smaller. It may seem counterintuitive, but small tiles can shrink a room visually due to the increased number of grout lines. Using medium- to large-format tiles creates a more seamless look. For the best effect, pair your light-colored tiles with a matching or similarly colored grout. This minimizes the grid-like pattern and gives the floor and walls a more continuous, uninterrupted appearance, helping the room feel significantly larger.

Tile countertops can be an excellent and budget-friendly option for a kitchen, provided they are installed correctly. It's important to choose tiles, such as ceramic, that are heat-, water-, and scratch-resistant. When the grout is properly sealed, it will resist stains, making the surface easy to clean. Tile is also considered a sustainable material. For a cohesive kitchen design and added protection, you can pair a tile countertop with a matching tile backsplash.

Mortar and thinset both serve the same purpose—tile adhesion—but have different compositions and use-cases. Thinset is heatproof and presents a wide range of possibilities due to the added polymers. Mortar is typically used for bonding stones and brick. Thinset is rarely used outside, while mortar is rarely used inside.
