Poor workmanship

Sorry to hear about the leak. A shower leaking a few months after install almost always points to the waterproofing, not anything you did. Common causes: a membrane or pan that wasn't sloped/sealed properly, grout used where flexible silicone should be (corners, wall-to-floor joints), a clogged or poorly seated drain, or an improperly waterproofed niche/bench. Note where the water shows up and when — it helps narrow the source. A proper diagnosis usually needs a flood test and a moisture read, not a guess from photos. Since the installer's gone quiet, put your requests in writing so there's a record, and keep your receipts. Most reputable installers carry a workmanship warranty.

Hello, I saw your HomeStars request regarding the leaking shower. A shower that was installed only a few months ago and is already leaking badly enough for you to notice is a serious concern. Something has clearly failed — it could be a plumbing or drain connection, or it could be related to the shower base, liner or waterproofing system. The best-case scenario would be an accessible plumbing issue that can be repaired without disturbing the shower. However, if the leak is coming from the waterproofing system or shower base, a substantial portion of the shower may need to be removed and rebuilt properly. Since this installation was completed only a few months ago, I would first recommend pursuing the original installer for warranty or correction of the work, particularly if you have a written contract or warranty. If that is no longer an option, please keep in mind that properly correcting this type of problem can involve significant work and additional cost. I understand that you have already recently paid for the shower, so if you are prepared to invest again to have an experienced contractor properly investigate and correct the problem, I would be happy to discuss it with you.

Could you please explain which part of shower is leaking?

Question is your shower leaking from the door or drainage or elsewhere? If is the door make sure that you have silicon between the walls and shower door profile.

The first step is to identify exactly where the water is coming from. Common causes include a failed drain connection, a plumbing leak, improper waterproofing behind the tile, failed grout or caulking, or an issue with the shower enclosure. If the leak appears to be coming from the plumbing or drain, a plumber should take a look at it. However, if the source isn’t clear or you need a more holistic assessment of the shower installation, a general contractor can inspect the entire assembly, identify the likely cause, and recommend the proper repair.
