Before we go further, let’s learn about shower pans and shower bases. 

Shower Pan Vs Shower Base

While a shower pan and a shower base both channel water into a drain, there’s one key difference: “Shower pan” is the shower floor that you step on, whereas “shower base” refers to the structure underneath the shower itself.

Shower Pan Vs Shower Base

While these two terms are interchangeable, it is crucial to know the difference. 

What Is A Shower Pan?

A shower pan, also known as a shower bed, is a separate area in a walk-in shower for example, that directs and maintains water flow to the drain. The pans come with a drain hole and a slow floor that helps guide water in the direction it’s meant to travel on your shower floor.

Shower pans are easy to install. They come with installation kits in a variety of sizes. But a shower base will require more time to install versus a shower pan that can easily fit in place.  

What Is A Shower Base?

A shower base is a structural base that sits underneath a shower pan. This references the layer of mortar and liner sitting on top of your subfloor beneath the shower pan. Shower floors range between 32 inches x 36 inches

Having a liner or sealant put down before the mortar will ensure your subfloor doesn’t get wet. If you’re replacing an old one with a new shower pan that’s standard size, you’ll also need to use liner or sealant.

6 Easy Steps For A New Shower Base

  1. Tack a waterproof pan liner down: after removing your old pan, make sure there is a clean, make sure the surface is dust-free before you begin.
  2. Dry fit the new pan so it is level. Place two levelers on both sides of the pan. If one side is lower, add shims until the pan levels out and tack those in place.
  3. Use Plumber’s putty to secure the drain to the pan. 
  4. Your mixed mortar should be a peanut butter consistency; apply about an inch layer to the liner. Do not get it in the drain hole.
  5. Place the new pan into the mortar on the shower floor.
  6. The mortar will expand while it dries. Add temporary strapping to hold it in place.

NOTE: Allow one day for the mortar to dry.
