Inside and outside corners are the most common obstacle in any tile layout. When a tile needs to wrap around a corner, a doorframe, or a cabinet edge, you're making what's called an L-cut, essentially removing a rectangular notch from one corner of the tile so the remaining piece slides into place.

The cleanest way to make an L-cut is with a wet tile saw. Mark your cut lines on the tile face, then make two straight plunge cuts that meet at the inside corner of the notch. Because a standard blade is round, it won't cut a perfect inside corner on its own; you'll finish the last bit of material with tile nippers or a quick pass with a grinder fitted with a diamond blade. A 10in wet tile saw with a 21in cut capacity gives enough table space to control larger tiles through both cuts without the piece wobbling.

For small notches around baseboard returns or cabinet toe-kicks, a compact 8in wet tile saw is easier to maneuver on a job site table and still handles most residential tile thicknesses.

Cutting tile around plumbing, whether it's a shower valve, a toilet flange, or a supply line sticking through a wall, comes down to getting an accurate hole in the right spot. Measure twice from two fixed reference points (like the tile edge and the floor line) to find the exact center of the pipe, then transfer that mark to the tile.

For round cutouts, a diamond hole saw is the right tool. These come in graduated sizes, and matching the hole saw diameter closely to the pipe diameter keeps the cutout tight enough that a flange or escutcheon plate will fully cover any gap. Rntr providers carry a full range, including a 1-inch diamond hole saw, 1 1/2-inch, 2-inch, and up to 3-inch for larger drain and vent pipes.

If a pipe sits near the edge of a tile rather than in the middle, you may need to combine a hole saw cut with a straight cut on a wet saw, essentially cutting the tile in half through the hole. If you're removing an old shower valve or supply line to get better access before tiling, a heavy-duty 14-inch pipe wrench makes quick work of stubborn fittings without renting a full plumbing tool kit.

Cutting tile around electrical outlets, especially on a backsplash, is one of the more common obstacle cuts homeowners run into. Outlet boxes are rectangular, so unlike a pipe cutout, you're combining straight plunge cuts with a corner notch, similar to an L-cut but on all four sides.

Mark the outline of the outlet box directly on the tile using the box itself as a template, then score and cut each side on a wet tile saw, stopping short of the corners so you don't overcut into the visible face. Clean up the corners with tile nippers or a small grinder pass. On porcelain backsplash tile, take it slow. Porcelain is dense and brittle at the same time, so a rushed plunge cut is the most common cause of a cracked tile right before installation.

Always cut power to the outlet and pull the cover plate before you start measuring, and never rely on a wet saw near a live electrical box; for general guidance on staying safe around water and electrical components on a job site, see this guide on operating equipment safely around water and power. A saw core wet tile saw gives a stable table setup that makes these smaller precision cuts easier to control than a handheld cutter.

A single wet tile saw handles most straight cuts, notches, and L-cuts. For the specialty cuts, plan on having a few additional tools on hand:

Tile nippers for cleaning up small corners and irregular edges where a blade can't reach.

A diamond hole saw set for round cutouts around pipes, valves, and shower arms.

A spare diamond blade if you're cutting a mix of ceramic and porcelain, since porcelain wears blades faster.

A tape measure and marker for transferring obstacle locations accurately, since most cutting mistakes come from a bad measurement, not a bad cut.

Most providers list the 10in wet tile saw with a 31in cut capacity for larger format tile jobs where you need extra table length to support the full piece during a corner notch cut.
