What is the process for replacing a bathtub?

If your Phoenix home has a bathtub that seems to date back to the 1800s, you’re probably considering getting a bathtub replacement. By upgrading your bathtub, you can enjoy everything that 21st century bathtubs offer–including multi-speed jet settings, digital controls, and even resonant speaker panels for music. Needless to say, there are plenty of reasons why you should install a new tub. That means only one questions remains: how do you replace a bathtub?

Do It Yourself?

An enameled steel bathtub can weigh 75 pounds; cast iron can weigh over 300 pounds. Because many tubs are very wide, tubs are often installed before the door is cased out. To take a tub out, you may need to break it into parts or remove the door and doorframe.

Due to the difficult steps that are involved, most Phoenix homeowners opt to have professionals remove the old tub and install a new one. If you insist on doing the job yourself, the steps are straightforward and will likely take a full weekend to accomplish.
