2026 DIY Dad’s Note: Wainscoting Finish to Toilet Installation

The most demanding phase of the toilet renovation. Once the wainscoting is finished, it’s on to setting the new toilet bowl u2014 and at that point the end is clearly in sight. ^ ^

Attaching the Tank

Hi, this is DIY Dad. ^ ^ Last night’s snack was pork tenderloin cutlet u2014 sliced straight from the loin and deep-fried. Tender and delicious! I learned a tip: mix the egg and flour together before dipping, instead of doing them separately. The breadcrumbs stick much better. A revelation u2014 though maybe everyone else already knew that? (Laughs.)

Continuing the first-floor toilet renovation. Today: attaching the tank.

Tools and materials: tank body, gasket, nuts, wrench.

1. Set the gasket (rubber seal) between the tank and the toilet body
2. Lower the tank onto the toilet body
3. From underneath the toilet, tighten the nuts to secure the tank

4. Fit the flush lever and the chain inside the tank

5. Attach the hand-rinse nozzle to the tank lid

Waiting for the Drain Joint to Cure

Once the tank is assembled, there’s a waiting period. I used silicone caulk instead of the manufacturer’s recommended PVC cement to join the drain connector u2014 which means the joint needs time to cure before water can be held in the bowl.

Normal cure time for silicone is 10u201315 minutes, but I applied it generously, so I decided to leave it for a full day to be safe. In the meantime, I sealed the drain opening with masking tape to stand in for the water trap.

Even just replacing the toilet bowl makes a dramatic difference to the feel of the room. Upgrading to a modern toilet with a built-in washlet is a change DIY Dad has applied to every property in his portfolio. ^ ^
