Toilet Installation in Whitby

A new toilet should flush well, sit solid on the floor and stay sealed for years. Getting there hinges on the rough-in, the flange and the care taken setting it.

Kit on the van, and the method

  1. Basin wrench and seat wrench
  2. Wax rings, closet bolts and flange repair rings
  3. Cartridges, stems and seats for common valve makers
  4. Toilet auger and closet plunger

Before we leave: Cycle the fixture hot and cold, check every joint dry with a paper towel.

Choosing a model

The first measurement is the rough-in: the span between finished wall and the middle of the closet bolts. A 12 inch rough-in is standard locally, though certain older homes and some basement bathrooms have 10 or 14. Buying the wrong size means the toilet either will not fit or sits awkwardly far from the wall. We measure before you shop.

After that, the choices are about comfort and flushing:

  • Standard or comfort height bowl.
  • Round or elongated bowl, which matters in small powder rooms.
  • Single flush or dual flush.
  • Two-piece or one-piece, and whether the trapway is skirted for easier cleaning.

High-efficiency toilets are rated near 4.8 L a flush or lower, and the better models clear waste well. Some municipalities and utilities have offered rebates for replacing older high-volume toilets; check what is currently available before buying.

Field note. Older toilets in Whitby houses can use 13 litres or more per flush. In a family home that adds up on the water bill.

Installation steps

  1. Isolate, empty and lift out the existing bowl, then stuff a rag in the opening against sewer gas.
  2. Inspect the flange: height, condition and how firmly it is anchored.
  3. Check the subfloor for soft spots from old leaks.
  4. Install new closet bolts, seal, and set the bowl level.
  5. Bolt the tank on, fit a fresh braided connector and swap a tired stop.
  6. Test flush repeatedly and check for leaks at every joint.
  7. Caulk around the base where appropriate, with the rear left unsealed so any later leak reveals itself.

Removal of the old toilet

The old bowl leaves on our truck; the garbage crew will not take it from the curb.
