When creating a tile shower, pan installation before you begin your project is one thing you should definitely consider carefully. Chances are the existing pan will not be proper for the new shower you are creating and replacing the pan will give you an opportunity to properly inspect all the things below the surface of your shower floor before going to all the hard work of tiling your shower. The important thing is it will give you a chance to identify problems or potential problems before making a huge investment of time and money in your project.
Even if you aren’t working with tile, shower pan installation is the best place to start when installing a new shower. If you’ve elected to buy the pre formed showers you will still need the foundation of a good shower pan along with a good understanding of the condition of the sub floor and drain below.
It is always best to take the time to identify problems or potential problems before beginning a new project of any kind, especially when dealing with plumbing however as small problems can lead to big and sometimes costly (financially and health wise) results.
Once you remove the existing shower pan you should thoroughly inspect the sub floor beneath the shower pan for signs of damage due to water, age, or anything else. If the grout was damaged in the existing shower pan chances are that there will be some degree of water damage that will need to be repaired before moving on with your tile–shower pan installation project.
Proper Pan Procedure
When it comes to tile shower pan installation you should start by applying a layer of roofing felt to your floor. Then you will want to create a mixture that is five parts sand and one part cement. Lay the mixture over the felt; it should be sloped downwards in the middle towards the drain.
Once you have created the desired slope you should then smooth the pan over the concrete that has been sloped and up the wall for around 10 inches. This pan should also be wrapped over the ledge that exists for the doorstep. Doing this will maximize the area of protection from damage or weaknesses that can be caused by excessive exposure to water.
After this has been accomplished you should make sure that the corners are not leaking in any way. The next step is to surround your drain with crushed stones (in order to allow any water to flow into the weep holes), which you will then cover with a mortar bed that slopes toward the drain.
Then you can begin to lay the actual flooring of your tile shower and will be able to have some major bragging rights for surviving the somewhat complicated process of a tile shower pan installation. Once you’ve completed the tile shower pan installation you can begin to finish the installation of your entire shower.
While the process may seem a little difficult you will more often than not find plumbing instructions when you purchase the parts required to create the shower pan. If there are ever any questions you should never hesitate to ask.
You should also inquire when you purchase your parts as to whether there are any special or unusual requirements you should be aware of when you perform the actual tile shower pan installation. The good news is that while there are several steps, they are generally fairly easy to follow.
