Building the Bathroom: Enclosing the Walls

I’m finally back! It’s been almost 2.5 months – the longest I’ve been away from London and the flat for quite some time. I’m gearing up for a busy couple of weeks, because we’re on a tight schedule – “Aglaya” booked a tiler to start work in the bathroom on February 20th, so I have exactly 7 days to finish all of the build-out, waterproofing and prep work before he can start. We had originally thought about just tiling the shower for now, but we soon realized that 4/5 of the work (and the cost) would be the shower. At that point we realized that it made sense to give it just a little more time and money and simply get the whole room done as part of our Big Push. It’s going to be tight – there’s a lot work to be done, but I think 5 days should be enough…

In December, I had completed most of the shower’s build-out and installed most of the Marmox tile backer board on the walls. What remained was completing the shower’s base, and building out the ledge and walls of the bathroom (outside the shower), which will be soon covered in limestone tiles. The only work done on these surrounding walls (so far) was the basic stud framing, so they would have to be covered in plywood, waterproofing and Marmox backer board. For the ledge, it would have to be framed out, and then covered in the plywood, waterproofing, etc.
February 13 - the exposed wall studs
The most exciting part of this will be closing up our temporary door, removing the blue tarp and building out the real door we will eventually be using every day. The real door will be on the opposite side of the room from where the current, temporary one is. In the final layout, the bathroom will be en-suite, accessed from the bedroom.
Before starting - looking the other way towards the temporary door (shower on the left)
I started by laying out the ledge – the idea here is that it wraps almost completely around the bathroom and into the shower, so we can put thing on it while providing a place to transition from stone to mirror. I framed out the ledge using short studs fastened to the full-height wall studs. This ledge also had to hide the cistern of our new toilet, so had to take it into consideration with the dimensions and layout.

Using a string line to framed-out the ledge & keep the studs aligned
End of the day - ready for plywood in the morning
Once the studs were in, I used a string line to find the level and started attaching sheets of waterproof/boil-proof plywood (WPBP) that would act as the substrate for the waterproofing and tile backer boards. The plywood also helps tie everything together structurally, while minimizing any movement that might cause the tile or grout to crack in the future. In doing this, the larger the piece of plywood, the better job it does tying everything together, so this required some rather intricate cutting.
Morning of Feb 14th - first piece of plywood
Second piece had lots of intricate cuts

Installing the second piece behind the toilet
Lower part of the wall/ledge completed
Once the long wall (where the toilet is located) was finished, I moved on to the shorter wall (where the sink will eventually go). This is where our temporary door is located, so for the time being I’ll finish everything but a narrow opening. If we weren’t living on site while doing the work, I wouldn’t have to worry about this (and just close up the temporary door now), but I’d prefer to minimize having to going in and out through “The Box” – particularly once the tiler starts his work which can be quite messy. So in the meantime, we have this workaround…
