Chisel Out Wall Recesses — Plan and Mark Location
Part of project
How to Install a Waterproof Foam Shower Niche · Step 1 of 6
In this video
With the shower tray removed, use a hammer and a sharp chisel to carefully remove the timber inside the marked lines on the studs and bottom plate. The goal is to create a 10mm deep recess. For the bottom plate, mark a 10mm line from the front edge and chisel back to that line. This ensures the shower tray can sit snugly into the framing. A hand saw can also be used to make vertical cuts into the studs to make chiseling easier.
Goal: Create a 10mm recess in the framing for the shower tray
- Be careful when chiseling not to remove too much wood or damage the surrounding framing.

FAQs
The project is listed as 'beginner' difficulty, but 8 hours seems like a long time. What makes this project take so long, and is it truly suitable for a first-timer?
While the individual steps are straightforward, the 8-hour estimate accounts for careful measuring, precise framing, allowing sealant to cure, and meticulous waterproofing. Rushing these critical steps can lead to leaks, so taking your time to ensure everything is perfect makes it beginner-friendly by emphasizing accuracy over speed.
The required tools list several different drills. Do I need multiple drill/drivers, or will one standard cordless drill suffice for this project?
You only need one capable cordless drill/driver, such as the RYOBI ONE+ 18V Cordless 1/2 in. Drill/Driver, to complete this project. The multiple listings provide options for suitable tools. Ensure your chosen drill has enough power to drive screws into wood studs and backer board efficiently.
What is the most critical step to ensure the shower niche is completely waterproof and won't leak?
The most critical step is the meticulous waterproofing of all seams, especially where the niche meets the backer board. Apply a continuous bead of high-quality waterproof sealant like DAP Ultra Clear, and then properly embed waterproofing banding over all seams and fasteners. This creates a monolithic, leak-proof barrier essential for preventing water damage.
What if my existing wall studs aren't perfectly spaced for the pre-fabricated niche? Do I need to modify the framing?
Yes, you will likely need to modify your wall framing using 2x4 lumber to create a precise, sturdy opening for the niche. This often involves cutting existing studs and installing horizontal blocking to perfectly frame the niche's dimensions, ensuring a flush and stable installation. Accurate framing is crucial for long-term stability and waterproofing.
