​Showers are a daily habit for most of us, meaning that the shower in our bathroom gets a lot of use. ​When you add in the fact that, a lot of the time, the shower gets used by multiple family members each day, its not hard to see why your shower floor might show signs of wear as the years go by.

We've put together a guide for how to repair your shower floor. Often, your repairs will be simple and painless.

Once in awhile, it might be time to move on and replace it. We'll walk through each of the steps.  

​How to Repair a Fiberglass Shower Floor

​​While fiberglass showers and bases are a more affordable and highly durable option, sometimes cracks and holes occur.  Unlike shower heads that need replacing when in need of repair, you can ​often fix the area instead of having to purchase a brand-new shower.

This fix can be relatively easy. It may just take extra steps depending on how much damage there is. Consult your local home store and speak with a DIY specialist to figure out what type of epoxy kit you will need when you are fixing a shower floor. Make sure all of your sinks, faucets, and even your fancy rain shower heads are turned off and arenn't leaking before you begin the process.

When it comes to repairing a shower pan, follow the steps on your epoxy kit. This general overview of the steps required will give you an idea of what this not-so-difficult DIY project entails.

​Tools

  • ​Protective gear (gloves, respiratory safety glasses)
  • ​Sand paper
  • ​Fiberglass Repair Kit

​Steps to Repair

  • 1
    First, clean and prepare the area. Use one of ​methods we've outlined to clean the shower pan or tub. Follow up by rubbing the entire afflicted area with acetone or rubbing alcohol to remove any leftover oils.
  • 2
    Make sure you put on your gloves and other safety equipment before you begin the next step. Keep your ​shower doors open as well and​ make sure your bathroom fan is on to help ventilate the area so you don’t inhale strong concentrated fumes.
  • 3
    For minor crack or holes, use the included resin putty mix to pour in and seal over the crack as you would chipped tile. If your bathtub or shower pan is not white, you will need to add in a colorant, which can be purchased along with the kit, to match it.
  • 4
    As soon as it is mixed, pour the filler onto the area. Contain the mix to the area, but don’t worry about piling the mixture into the hole. You will be sanding it down later.
  • 5
    If you are using fiberglass mesh, lay it down before you begin pouring. The mesh works as a bonding tape to hold the area together while also creating a strong barrier.
  • 6
    After you finish pouring, allow the mixture to set for 2-3 hours. This will allow the resin putty mixture to dry on the surface and below in the crack. Similar to wall paint, the outside may dry faster. But, you do not want to disturb the area until the inside has had time to bond and completely dry.
  • 7
    Next, begin to sand the area. This step allows you to smooth over the surface. It also brings the shower bottom back to the same level as the rest of the bottom of the shower pan. Depending on how large of a pile you have, it can take a little time and elbow grease to get the repaired area to not be as obvious.
  • 8
    Finally, follow up with a finishing polish to seal the patch and allow the area to blend into the rest of the shower base.

These steps are best for minor cracks. If you are dealing with a good-sized hole or a structural weakness in your shower floor, it will take a few more steps. Instead of pulling out the full shower flooring to replace it, take a drill and create eight small holes around the weakened area.

Inside those holes inject a two-component foam. This foam will create a new and stronger base for your shower floor without you having to rip it up and rebuild a support system.

Then, follow the above steps to cover and fill the crack with the epoxy resin putty and sand it down once it fully dries. This has practically the same methods you would go for when grouting tile for your bathroom and home.

When it comes to repairing a shower base, it can take about a day’s worth of work. Much of the time will be spent waiting for the materials to dry between applications.

You can also do this job from anywhere between $25 - $250 dollars depending on the severity of the damage.

​How to Maintain Your Shower Floor

Now that you know how to clean a textured fiberglass shower floor, the next step is to maintain it from getting scum buildup. Learning more about how to soften water in the shower can help you prevent any mineral or rust buildup.

Put into action these easy tips when you want to keep your shower clean from daily buildup.

  • ​Quickly wipe the shower done after each use.
  • ​Keep the shower well ventilated so it dries between uses.
  • Opt for liquid soap instead of bar soap. Bar soap contains talc which aids in the development of soap scum buildup.

​If you have a shower floor made of tile, then you'll need to go through different steps to maintain it. The biggest risk with this kind of floor is the grout wearing away over time. 

Make sure to occasionally use one of the best tile floor steam cleaners to work the dirt and grime out of your grout. These types of cleaners are specifically designed to work with tile and grout, and will you maintain your shower floor over time.
