u270fufe0f 2026 Update from DIY Dad: Key Points for the Finishing Stage

Washlet Toilet Seats (Bidet)
A washlet seat is the single upgrade that impresses every tenant in Japan.
We’re now at the finishing phase of the toilet renovation. Once all the accessories are removed, it’s time for the floor and wall finish work. Because a toilet is such a small, compact space, the quality of the finish is immediately obvious. ^ ^
Removing Toilet Accessories (Paper Holder, Towel Ring, etc.)

Toilet Repair Kits
Keep a repair kit stocked u2014 toilet calls come without warning at midnight.
Before applying wallpaper or diatomite plaster, remove everything attached to the walls.
What to Remove
- Toilet paper holder
- Towel ring / storage shelf
- Outlet cover plate
- Light fixture (if needed)
- Ventilation fan cover
If you try to work around these items, your finish will look sloppy. It’s a rule: no matter how tedious it is, remove everything first. m(_ _)m
Floor Repair and Cushion Floor Replacement
After removing the toilet bowl, you’ll be left with anchor bolt holes in the floor. If the new toilet’s drain flange aligns with the existing holes, you can go straight to laying the new cushion floor (CF) and installing the new toilet.
The hardest part of cutting CF is cutting out the hole for the drain flange. Make a paper template and cut carefully.
DIY Dad’s tip: Make the template for the drain area slightly smaller than the actual opening, then gradually expand it on-site for a better fit without over-cutting. ^ ^
Why I Chose Diatomite for the Toilet Walls

Toilet Accessories Sets
Matching accessories cost u00a52,000 and make a small toilet feel designed.
For this toilet renovation I applied diatomite plaster to the walls instead of wallpaper. My reasons:
- It absorbs moisture and odors (diatomite’s natural humidity-control and deodorizing properties)
- I’d already used it in the Japanese-style room with great results, so I continued with it
- It creates a more distinctive, premium look than wallpaper
Diatomite does take some practice to apply well, but in a small space like a toilet it’s also a great opportunity to build your technique. DIY Dad’s trowel skills improved considerably working in this tight space. (Lol) u0669( u141b )u0648
Diatomite Application Tips (Toilet Edition)
- Thoroughly mask around the toilet bowl and tank with masking tape
- Protect the water supply pipe and shutoff valve with plastic wrap
- Mask around the ventilation opening and outlet
- Peel off masking tape immediately after applying u2014 before it dries
If you wait until the diatomite dries before peeling the tape, it will tear the surface with it. The rule is: peel the moment you finish applying. m(_ _)m
As a Landlord: Cleanliness u00d7 Functionality Changes Your Occupancy Rate
A toilet with diatomite walls, brand-new cushion flooring, and a fresh washlet-equipped bowl u2014 the reaction from prospective tenants was noticeably different. I heard “Wow, this bathroom is so clean!” again and again. ^ ^
Total material cost for the DIY toilet renovation: around u00a580,000. A contractor would charge u00a5300,000u2013500,000 for the same work. Huge savings through DIY.
ud83dudebd For Anyone Considering a Toilet Renovation
Even just replacing the toilet bowl can dramatically change the feel of the space. Going from a tank-type to a tankless toilet in this property gave the room a completely different sense of spaciousness. ^ ^
Water leaks and clogs get worse if ignored u2014 call a professional right away when trouble strikes.

Hi there, it’s DIY Dad. ^ ^
Happy Friday! Coming right off the New Year break and already another long weekend is coming up. Going to be hard to avoid overdoing it again. u266a(*^^)ou2200*u2200o(^^*)u266a
Continuing on with the 1st-floor toilet renovation. Next up: removing the outlet panel, towel bar, paper holder, and ventilation fan. Tools and materials: impact driver, screwdriver, masking tape.
First, removing the outlet next to the toilet. I opened the outlet cover u2014 and the outlet bracket was completely corroded! (-_-;) Rust all over, crumbling apart. The back of the outlet where the wiring connects was covered with a greenish solid residue. (-uff61-; I’d just seen the deeply stained floor left by the old toilet bowl, so at this point I was barely surprised. d(uffe3 uffe3) Impressive that it hadn’t shorted out. ^^; The outlet bracket was so disgusting I just tossed it u2014 unfortunately missed getting a photo. (._.)
Next, removing the ventilation fan. The cover is a clip-on type. I popped it off:
