Replacing a Bathtub

Many “Do It Yourselfers” replace bathtubs on their own.  However, replacing a bathtub requires a lot of planning. With a bathtub project, there are many points to consider and many things that could go wrong. We will list some of the project considerations below:

  • Removing your old tub means that you will need a route to carry it out of your home. You may have to remove other bathroom fixtures such as a sink or toilet, remove entry doors, and you may even need to consider whether you can remove your old tub in one piece.
  • Removing your old tub could cause damage to your floors and walls. It can be difficult to remove a bathtub and often times wall surfaces and tiles are damaged when the old tub and the caulking are removed.
  • Check your local plumbing code. Many municipalities require an inspection by the local plumbing inspector. NRH Plumbing guarantees our work and we will check all municipal codes to ensure your home stays in compliance.
  • Check the dimensions of your old tub. This is not only important for planning the exit route, it also lets you know how it compares to your new tub.  There are two sizes you’ll be choosing from when you select your new tub: standard sized tubs and larger tubs. The available space in your bathroom will help you choose between the two. Standard tubs can hold about 50 gallons of water and are 60 inches long and 30 inches wide. Since they have a standard size, they can easily fit through doors or up a flight of stairs. If you have your heart set on soaking tubs, whirlpool, or combination tub, they will be larger in size and heavier than standard-size tubs. They may be hard to transport and maneuver through doorways and stairwells.
  • Speaking of weight, double check the material of your old tub and compare it to your new tub. Oversized whirlpool and soaking tubs will be heavier than standard tubs. Material can also increase the weight of a tub. Fiberglass tubs will be lighter than metal or ceramic tubs. Double check that the floor joists are built to accommodate the weight of your new tub.
  • Compare the connections of the new tub to the old one to make sure it fits properly. The waste and overflow need to be attached perfectly to guard against leaks and damage to your plumbing system. Supply lines also need to be properly sized for efficiency
  • Finally make sure your water heater can handle the capacity if you choose a larger bathtub.
