Wallpaper Tips for Laundry Rooms (Vol.5)
Wallpapering in a laundry/changing room demands more moisture-resistance than a typical room:
- Choose wallpaper with anti-mold properties (essential)
- Apply caulk behind the vanity and around the bathroom door frame
- Breathable wallpaper is preferable u2014 it lets moisture escape
- White and light tones are popular for a clean, fresh look
This room gets hit with humidity every single day at bath time. Taking moisture-resistance seriously keeps the interior looking great for years.
Cushion Floor Tips (Vol.6)
The cushion floor in a laundry room must handle wet conditions:
- Choose a water-resistant CF rated for bathrooms and laundry areas
- Install base molding at wall joints to prevent water from seeping underneath
- Caulk around the vanity legs for waterproofing
- Minimize seams in the CF u2014 each seam is a potential entry point for water
Vanity Installation Tips (Vol.7)
Replacing a bathroom vanity is genuinely DIY-friendly:
- Remove the old vanity
- Set the new vanity in position and secure it to the wall
- Connect supply and drain lines
- Open the shut-off valve and check for leaks
- Caulk around the vanity perimeter

On the opposite wall, I used the same pattern as the other rooms. In rental properties, keeping wallpaper patterns consistent across units makes maintenance much easier u2014 though DIY Dad usually forgets the model number anyway and ends up scrambling at move-out time!
