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. ^ ^

Setting the Toilet Bowl

Hi, this is DIY Dad. ^ ^ It’s looking like another cold week ahead u2014 stay warm everyone. My throat is a bit sore today.

Continuing the first-floor toilet renovation. Today we get into the actual bowl installation.

Tools and materials: toilet bowl, silicone caulk, impact driver, hex wrench.

For this installation, the distance from the wall to the drain centre matched the new toilet’s specifications, so no major floor modifications were needed. ^ ^

Installation Steps

1. Adjust the height of the drain pipe connection u2014 this doesn’t need to be precise
2. Tape the included layout sheet to the floor and mark the anchor bolt hole positions
3. Fix the mounting bracket to the floor with screws
4. Attach the drain connector to the toilet’s drain outlet

The manufacturer’s instructions call for PVC solvent cement to glue the drain connector in place. However, if you use PVC cement and something goes wrong, there’s no going back u2014 the joint is permanent. I was a little nervous about that, so I tried silicone caulk as a substitute. If there’s a problem, the joint can be cut apart and redone without touching the existing drain pipe.

Note: this method carries a risk of leakage. Follow the manufacturer’s recommended installation method for a reliable result.

5. Apply a generous bead of silicone caulk to the drain connector and press it down over the drain pipe

DIY Dad’s Toilet Selection Criteria

For a rental property, the key considerations when choosing a toilet:

• Integrated washlet vs. separate bidet seat: integrated looks sleeker but requires replacing the entire unit if the electronics fail; a separate seat can be swapped out on its own u2014 better value in the long run
• Tank-type vs. tankless: tankless creates more space but is expensive and requires adequate water pressure; tank-type is more cost-effective
• Water-saving model (5 L or less per flush): reduces water bills over time

DIY Dad’s choice: a water-saving tank-type toilet body with a separately fitted washlet seat u2014 the best balance of cost and practicality. ^ ^
