How to convert toilet to bidet

Updated April 17, 2017

For many years bidets have been popular in Europe and the Middle East. Over the past several years, bidets have started to become more popular in the United States. Most bathrooms do not have space for a bidet, however. Some manufacturers now sell conversion kits that allow a homeowner to convert their toilet to a toilet/bidet. These products are inexpensive and easy to install with ordinary household tools.

Close the valve that supplies water to the water tank on the toilet. Flush the toilet to remove water from the tank. Use shop towels to absorb the rest of the water in the water tank. Remove the water supply hose extending from the water supply valve to the toilet water tank

Use a screwdriver to remove the toilet seat. Move the toilet seat to a level work area. The bathroom sink area should work well for this. Clean and dry the bottom of the toilet seat.

Attach the spray apparatus to the base of the toilet seat according to manufacturer's instructions. Each bidet will be slightly different. The spray nozzle should be directly at the back underside of the toilet seat facing up.

Attach the two-way valve that was supplied with the bidet to the toilet water supply valve. Use Teflon tape on the threads of the valve where it attaches to the water supply.

Attach the toilet water connection to one outlet of the two-way valve and to the base of the toilet water tank. Attach one end of the bidet water hose to the other outlet on the two-way valve and the other end of the bidet water hose to the bidet. Use Teflon tape on all connections.

Turn on the water valve and check for leaks. Check the operation of the bidet.
