Before Installing Your Freestanding Bath Tap

Take note of the following as you prepare to set up that floor-standing mixer:

  • The floor-mounted mixer must be installed by a licensed plumber.

  • Be aware of the mixer’s maximum water temperature and the ideal operating pressure.

  • When cleaning, just wash with soapy water then dry with a soft cloth. Never use solvents, alcohol, chemicals or abrasives that may ruin its surface beyond repair.

Steps in Installing a Floor-Standing Bath Mixer & Tap

After preparing the tools and materials that you will need, unpack the mixer set and make sure that all the parts are complete. Now shut off the water supply valves to avoid getting wet and sprayed all over.

A floor-mounted bath spout can be installed with either the concealed under-floor box method or the above-floor connection method. The concealed box method is advisable before the flooring is installed, and has the benefit of a lower profile floor plate, which is preferred. The above-floor method may be done where the first approach is not possible.

Method 1: Concealed Box Installation

Let's do this!

Step A: Attach the inlet tube to the faucet by twisting firmly. Twist the straight tube on to the top faucet and make sure it's tight enough to avoid leaks and loosening.

Step B: Place the concealed box on the ground and use the level to make sure that it is perfectly level with the ground. Screw the concealed box on the ground.

Step C: Unscrew and remove the plate. Knock out the level from the back of the plate.

Step D: Your licensed plumber installer should connect the source of the hot water and the cold water to the inlet of the concealed box. Wrap the threads on one end of the pipe with pipe tape or Teflon tape, then screw the adapters into the female fittings.


Step E: Screw the plate on the bottom of the faucet base with hex screws, then insert the whole faucet body to the concealed box. Insert the inlet pipe to the hot and cold outlet tubs of the concealed box.
