In this video

To provide a solid fixing point for the shower wall lining, install a row of timber noggins (or blocking) between the wall studs. Measure the distance between the studs, just above the upstand of the shower base. Cut pieces of framing timber to this length using a circular saw. Fit the noggins horizontally between the studs and secure them in place with a nail gun or hammer and nails. Repeat this for all sides of the shower enclosure.

Goal: Provide support for the shower wall lining

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.

cleaned up all the excess mortar mix. I need to put a row of nogs around the bottom of the shower tray to hold the lining of the shower. We're now measuring our nog 423. We're now cutting our nogs and now on to position. We're now going to install our nog just above the shower tray and now it off with our nogum. All our nogs have been put in in the correct position and now the base is finished. All we need is for the plumber to come and fit us pipes.
