Large-format tile can give a shower a calm, open look with fewer grout joints to clean. It can work on shower walls and, with the right tile and layout, on the floor too. The larger pieces leave less room to hide uneven surfaces or poor planning, though. Before choosing a tile, consider the shower’s dimensions, the floor slope, the drain location, and the installer’s preparation plan. These details determine whether the finished surface looks polished and directs water where it belongs.
Choose Tile for Each Surface
Large-format tile often suits shower walls because fewer joints create a continuous visual surface. Check the tile manufacturer’s guidance for wet-area use, and consider the tile’s weight, thickness, and finish. A polished surface may show water spots more readily than a textured one. Sample the tile in the actual room if possible, since lighting and nearby finishes can change how its color and pattern appear.
Shower floors require extra care. The floor must slope toward the drain, and a large, rigid tile may not follow that slope without lippage or awkward cuts. Smaller mosaics can adapt more easily to the pitch and provide more grout joints for traction. If you want large-format floor tile, ask the installer whether the shower design, tile size, and drain type can accommodate it safely.
Prepare a Flat, Sound Base
Large tiles make bumps and dips more noticeable. Before installation, the wall or floor needs to be stable, clean, and sufficiently flat for the tile being used. The installer should check the surface with a straightedge, correct irregularities, and confirm that the framing and backing can support the planned materials. Trying to compensate for an uneven wall with thick or inconsistent mortar can lead to poor coverage and uneven tile edges.
A tile surface alone does not make a shower waterproof. The shower needs a correctly installed waterproofing system behind or beneath the tile, with seams, corners, penetrations, and transitions treated according to the system’s instructions. Confirm how the waterproofing connects to the drain and how it will be inspected before tile covers it. Good preparation is difficult to see in the finished shower, but it is essential to its performance.
Plan Slope and Drainage
Water must flow across the shower floor to the drain without pooling. That requires a consistent slope in the base, not just careful tile placement. The drain type and position affect how the floor can be shaped: a point drain usually creates several sloping planes, while a linear drain may allow a simpler plane when the shower is designed for it. Coordinate the tile format, drain, and floor layout before construction begins.
Large pieces can bridge changes in slope, leaving corners unsupported or edges raised. The installer may need to use smaller cuts, adjust the layout, or choose a different floor tile to follow the pitch. After installation, water should move toward the drain rather than collect along walls or around the drain cover. Discuss how the installer will verify drainage before settling on a floor design.
Set Layout and Grout Joints
A larger tile does not mean grout-free tile. Grout joints accommodate small differences in tile size and help create a finished, cleanable surface. Joint width should follow the tile manufacturer’s guidance and account for tile variation; narrow joints may not suit every product. Ask to review a layout plan that shows where full tiles, cuts, niches, corners, and plumbing openings will land.
Tile pattern and joint placement affect both appearance and installation quality. A running-bond layout can create alignment challenges with some long tiles, so the manufacturer may recommend limiting the offset. Keep changes of plane, such as wall-to-wall corners, as flexible joints rather than filling them with grout. For a cohesive result, choose grout color with a sample and confirm how joints will be maintained over time.
Large-format tile can work beautifully in a shower when the tile suits each surface and the base, waterproofing, slope, and layout are planned together. Review the proposed tile and drain details with an experienced installer before work starts. Red River Tile can help you assess options for a Fargo shower project and plan the details with care.
