How To Repair A Cracked Bathtub

Most people will have to deal with a cracked bathtub at some point during their lives. Maybe the kids get carried away and drop a massive toy from a great height? Perhaps you manage to break it by standing up because the item has seen better days? Whatever the reason, you’ll need to perform repair work as soon as possible. Failure to do that could mean your tub begins to leak the next time someone uses your bathroom. Thankfully, the process is simple, but there are always professionals just waiting to help. So, don’t stress too much if you’re not the type of person who’s ever going to win awards for your DIY skills.

  • Locate the crack and clean

Before you do anything else, you need to make sure you can see the full split. Take the front panel off your bath and let the taps run for a moment. You should notice a drip of water coming from under the tub. Identify the affected area and mark it with a pen. You when need to clean the crack removing any grease or residue before moving onto the next step. It’s the most common home repair people make in the bathroom, and so we’re confident you can handle it without specialist assistance. However, you can always contact an expert if you’re concerned.

  • Use resin and hardener to plug the gap

Next up, you need to visit your local DIY store and ask for some resin and hardener. Explain your situation to the people working in that shop, and they should point you in the right direction. It’s important you purchase the right products because some resin is known to damage acrylic. So, it could make your bathroom issue even worse. When you have the right solutions, head home and apply the resin generously. Make sure you keep any pets out of the way because the substance is toxic. You then need to follow the manufacturer’s instructions when adding the hardener. Once that’s done, use a small brush to ensure the mixture covers the entire crack.

  • Sand the resin leaving a smooth finish

After twelve hours, the resin should dry, and your bath should become watertight again. You should now use some soft sandpaper to remove any lumps. Rub the paper over the area that contained the crack for ten minutes or so. That should reduce any swelling and leave you with a smooth finish. Some people like to apply more resin and repeat the process. However, you only need to do that if you’ve failed to cover the crack. Whatever you decide, always use the resin sparingly if you want to avoid issues.



That simple three-step guide should be enough for all readers to repair cracks in their bathtubs. So, I hope I’ve managed to save you some money today. Professionals will charge a callout fee, and they’ll also add a high hourly rate. That is why I don’t think you need expert help with easy jobs like this. Even the least skilled DIY enthusiasts would struggle to get this process wrong. If you require more advice or guidance, just look for some instructional videos on YouTube.
