Things You'll Need
Drill bit the same size as smaller pipes
Jigsaw for larger holes such as drains
Safety glasses or goggles
When installing beadboard paneling in a bathroom, it will likely be necessary to cut holes for pipes to fit through the paneling. There may be pipes for the toilet, sink or tub that go through the wall and will require a special round cut to create the hole for the pipes. With commonly available tools and careful measuring, you can create a neat and professional-looking hole in beadboard paneling around bathroom pipes.
Turn off the water supply and disconnect the pipe from the fixture as close to the wall as possible.

Measure the distance from the floor to the bottom of the pipe. Subtract 1/8 inch from that measurement then measure and mark with a horizontal line about as wide as the pipe the same distance from the bottom edge of the beadboard paneling.
Measure the distance from the last piece of installed paneling to the edge of the pipe. Subtract 1/8 inch from that measurement then measure and mark with a vertical line about as wide as the pipe the same distance from the edge of the piece to be installed. This vertical line should slightly overlap the horizontal line.
Measure the width of the bathroom pipe. Divide the width of the pipe by half and add 1/8 inch. Using this measurement, draw a second horizontal line above the horizontal line already on the beadboard. Use this measurement to draw a second vertical line that crosses the second horizontal line. This intersection is where you will locate the point of the compass.
Set the point of the compass where the second horizontal and vertical lines meet. While holding the point on the intersection, move the pencil side of the compass to the original bottom line. Rotate the compass to draw a circle that will be cut out for the pipe. The circle made with the compass should touch both the original bottom and side lines. If it does not touch both lines, check the original measurements.
Drill the hole with a drill bit slightly larger than the bathroom pipe if available. If the hole is for a large drain and a drill bit is not available, cut the hole with a jig saw. Use a drill to create a hole in the area to be removed for the pipe. Place the jigsaw blade in the hole and cut at an angle towards the circle drawn with the compass. Continue cutting on the circle until the area for the pipe is cut out.
Place the bathroom beadboard over the pipe and fasten to the wall. Reconnect the pipe and turn on the water supply.
Use the pencil lightly and remove remaining lines with sandpaper before painting or staining.
Always wear goggles or safety glasses while working with power tools.
