This is a complete overhaul u2014 tearing out the old toilet and starting fresh with new walls, flooring, and the toilet unit itself. Renovating the toilet in an older apartment is one of the highest-value improvements you can make. ^ ^

Toilet Repair Kits
Keep a repair kit stocked u2014 toilet calls come without warning at midnight.
- Vol.1: Demolition (remove toilet, strip wall material, pull up flooring)
- Vol.2: Entrance, wall & floor substrate framing (plywood & drywall)
- Vol.3: Wall putty work & wood frame painting
- Vol.4: Ceiling paint, wall wallpaper & cushion floor
- Vol.5: Combined toilet unit installation
- Vol.6: Silicone caulking & final inspection
By doing the full renovation myself, I brought the cost to roughly one-tenth of contractor pricing. m(_ _)m
Why Wall Putty Work Is Critical
Key points for substrate prep:
- Use compact materials suited to a small space
- Apply thorough moisture and waterproofing (it’s a humid environment)
- Map pipe locations before framing
- Repair or replace the door frame at this stage
Working in a tight space puts strain on your body. Take frequent breaks. ^ ^
Hello, I’m DIY Dad. ^ ^
Picking up where we left off with the wall and floor substrate. The wall has plywood overlaid on the existing tiles, with plasterboard above that, so I’m filling the gaps with putty compound. For putty tools and materials, see “Tools & Materials Vol.3: Wall Surface Prep u2014 5) Plywood & Plasterboard.”
