9 Tips to Install a Bathtub You Must Know

Mar 06,2023 | CASAINC

The bathtub is an extremely common appliance in modern life, and homeowners who need quality of life need to install the bathtub, but how should the bathtub be installed, and what are the precautions to be taken?


Before Installing:


  • Check the Tiles: The tiles should be placed after the bathtub has been installed. After the walls are done and then the bathtub is installed, knock off the tank below the mouth during installation to facilitate the insertion of the top of the bathtub, and finally trim it, which will prevent the bathtub from leaking water at the top when it is in use.
  • Choose the Right Bathtub Size: According to the specifications of the bathroom. According to the size of the bathroom in your own home, choose the right size of the bathtub in the pre-installation; first, compare the bathtub size and the space reserved for the bathroom.
  • Remember to Buy a Matching Bracket For It: Don't save money on the original brackets. Some tilers say, “We don't need to buy brackets! It's better to put sand under the bathtub than legs; the sand can support the bathtub and provide more heat insulation.” But the reality is that dry sand is fluid and less stable than the original feet.

While Installing:


  • Ensure the floor is Level: Move the bathtub to the desired location and mark it along its bottom. Set the bathtub upside down on a nonabrasive surface. Loosen the nuts and washers from the metal fame. Adjust  feet to align with the bathtub's bottom, as well as level the tub with the floor and then tighten the washers and nuts

(Note: Place the bath upside down on a dust sheet or soft cloth to not scratch the surface. Level the feet on the base of the bath and lock them into place.)


  • Choose the Right Pipe: Turn the bath upside down and fit either a P trap or an S trap (not supplied) to the bath waste, depending on the household waste pipe configuration. After extending the bathtub drain into the floor outlet, do a drainage test and do not leak the wastewater check.

  • Prolong the bathtub life:  For the stability of the bathtub and to prolong the service life of the bathtub, it is recommended to put glass glue on the contact area between the bathtub and the skirt and the wall, which will effectively keep the bottom of the bathtub dry and prolong the service life.


After Installing:

  • Clean Up: Use a soft cloth or sponge for cleaning. Do not use scouring pads like pot cleaners, which will dull the surface. Use mild soap and water for everyday use. Do not use abrasive cleaning materials. Do not use any disinfectants, aerosol cleaners, ammonia concentrates, etc. Give your bath a light polish with LIBRA acrylic polish every few months to restore the original sheen.


  • Last but not least: After the bathtub has been installed, it is important to consider what will happen later, so the bathtub underdrain system is usually checked and repaired. Underdrain systems for bathtubs are generally divided into concealed and open systems. Modern bathtub underdrain systems are prone to wear and tear and are difficult to replace when damaged if no access ports are created. The open type has a direct wall tile edge, and the concealed type is equipped with an access panel similar to the access panel for central air conditioning. The access panel can be used as a drainage outlet and does not require a separate drainage outlet. It can also be set up separately.
