How to Install a Bidet
Installing a bidet requires rough-in plumbing lines for hot and cold water and a drain, just like a vanity sink. Placement of a bidet is traditionally next to a toilet, so determine the location when designing the bathroom floor plan. To install a bidet, first determine the location for the bidet and make sure that the wall and floor are square and plumb to ensure a proper installation. Have a plumber run lines for hot and cold water and a drain to meet the rough-in specifications for the bidet.
Most toilet manufacturers offer bidets in styles and colors that complement their toilets. The most typical bidet features a single or two-handle faucet and vertical and horizontal sprays. Although many bidets are open, others incorporate a cover in their design.
Carefully read the installation instructions packaged with the bidet and identify the parts. To install a bidet, you need the following:
Bidet and its mounting nuts and bolts
Hot and cold riser tubes
Follow these steps to install a bidet:
Attach the faucet and drain fittings to the body of the bidet.
Move the bidet to its location and check the alignment with the drain and water supply pipes.
Draw a contour of the bidet on the floor and mark the location of the hold-down bolts on the floor.
Remove the bidet and drill pilot holes for the hold-down bolts.
You may have to use a carbide-tipped drill to bore through floor tile.
Use the contour drawn on the floor and reposition the bidet.
Insert the hold-down bolts and tighten them.
Use a carpenter's level to assure that the bidet is level.
Place the caps over the heads of the bolts.
Apply silicone sealant around the base of the bidet.
Connect the hot and cold riser (supply) tubes, shut -off valve, and drain.
Connect the water supply and drain and turn on the water to check for leaks.
If the bidet water supply doesn’t have a shut-off valve, add one with hot and cold flexible tubes with preattached fittings that connect the coupling nut to the bidet fitting and the compression fitting to the shut-off valve.
