Shampoo sinks are useful if you run a beauty business out of your home. These sinks require special manufacturing as they allow a neck space for users to lean back into for hair washing. Installing a shampoo sink is similar to installing a standard bathroom sink. The major difference is that some shampoo sinks might have just one faucet connection for cold water, instead of the normal hot and cold connections.
Attach the mounting bracket to the wall. Follow the manufacturer's instructions to measure out the proper height for the bracket. Some instructions will include a pattern that you can place on the wall to aid in measuring.
Mark the drill holes as needed and drill anchor holes. Insert the anchors into the wall, ensuring that they are flush. Position the mounting bracket and secure it to the wall with screws.
Attach the shampoo sink to the mounting brackets. Install any legs, if they are included.
Install the faucet(s). Roll out a bead of plumber's putty and press it into place on the underside of the faucets. Insert the faucets into position on the shampoo sink. Hold each faucet in your hand or have an assistant hold it while you position yourself underneath the sink.
Secure the faucet to the sink with plastic wing nuts from underneath. Wrap the inlets on the faucet and the water supply valve with plumber's tape. Connect the metal coupling on one end of the water supply hose to the water supply valve. Tighten with a wrench. Connect the other end of the supply hose to the inlet on the underside of the faucet.
Insert the tail piece into the underside of the sink drain. Twist counterclockwise to secure it. Slide the rubber washer and jamb nut over the end of the tail piece and secure them to the bottom of the sink.
Wrap the threads on the sewer inlet pipe and the tail piece with plumber's tape. Insert the p-trap into place between these pipes. Secure it with the couplings.
The above steps are just a guideline. Always follow the instructions included with your shampoo sink.
