How to Wax a Fiberglass Tub or Shower

Yep, you read that right – How to Wax a Fiberglass Tub or Shower. Believe it or not, it is a very good idea to wax a fiberglass tub or shower (even a sink) at least once a year. It is the same principle as waxing a car – it protects the finish and mainly keeps dirt from sticking to it. I am all for less cleaning!


I know I don’t necessarily have to mention this but I will anyway… DO NOT wax the floor of the tub or shower, for obvious reasons! You wouldn’t use Armor-All on the steering wheel of your car, right? Wax on the floor of a tub or shower is dangerous!!

For the example, Matt and I are cleaning out a shower (brand new) that has been sitting outside. We plan on using it in the bathroom of the Rebel house.


Start by giving the tub or shower a thorough cleaning. I normally use a handled sponge filled with Dawn dishwashing liquid and vinegar. It does a fabulous job! Thoroughly dry the surface using a cotton towel or chamois.

A special wax does not have to be used for the tub or shower! Plain old Turtle Wax does an excellent job and in fact, one of it’s recommended uses is for the shower or tub walls! Apply the wax according to the instructions – generously and with a soft cloth.
