Mold-Resistant Bathroom Caulk
Re-caulk every 3u20135 years. Black mold on caulk is the #1 tenant complaint in Japan.
The bathroom/laundry room is one of the more challenging DIY projects because of its wet-area nature u2014 but with the right approach, it’s absolutely doable.
Floor Work in the Bathroom/Laundry Room
The biggest challenge in this series was the full floor replacement: checking for joist rot u2192 repairs u2192 plywood subfloor u2192 cushion floor finish. This is among the more difficult DIY tasks in wet-area renovation.
What to Check Before Laying the Subfloor
- Measure joist spacing (typically 303mm = 1 shaku)
- Check joists are level with a spirit level
- Visually inspect and press-test for rot or termite damage
- Lay plywood sheets in a staggered pattern so seams don’t line up
Without staggering, all seams fall in a straight line and the floor clunks when walked on. DIY Dad caught this on the very first sheet and fixed it.
Tips for Laying Cushion Floor
- Make a paper template (trace the floor shape using roll paper or cardboard)
- Cut cushion floor 5u201310mm oversize, then trim to final fit on site
- Cut wall edges straight down with a utility knife (not at an angle)
- Spread adhesive evenly with a notched trowel, then press down while rolling out air
- Reinforce seams with seam-specific adhesive if the floor has joints
The bathroom/laundry room has a complex shape u2014 taking a careful paper template is the key to success.
Installing the Washing Machine Stand
Always confirm the floor is level before setting the waterproof pan. If it’s off-level, the washing machine will vibrate and wander during use. Also verify that the drain hole in the pan aligns with the existing drain location.
What DIY Dad Prioritizes as a Landlord
- Use seamless sheet cushion floor for easy maintenance
- Choose a washing machine pan shape that’s easy to clean
- Always verify the ventilation fan is working u2014 essential for mold prevention
- Caulk carefully at all vanity, pan, and wall joints
The cleanliness of the bathroom/laundry room directly affects occupancy rates. Cutting corners here always causes problems at move-out.

Hi, this is DIY Dad! Continuing the first-floor bathroom/laundry room renovation series.
Next up: fitting the washing machine stand. Tools and materials used: PVC pipe, PVC pipe adhesive, impact driver, jigsaw, and handsaw.
First, the drain connection for the washing machine stand must be created. The cushion floor was just laid u2014 and now a hole has to be cut in it. It’s a strange feeling to punch a hole in something you just finished cleaning up.
The stand is placed temporarily and the drain center point is marked.
