Toilet Replacement Cost Calculator

Rough-in is the distance from the wall behind the toilet to the centre of the hold-down bolts at the base. It's almost always 12 inches, but 10 and 14 inch rough-ins exist — particularly in older homes. Buying a 12 inch toilet for a 10 inch rough-in is the single most common reason a new toilet won't fit, and it's not returnable once it's been installed. Measure from the wall to the bolt caps before you buy anything, and bring the measurement with you.

Most toilet problems are a serviceable part: a flapper or fill valve fixes running and phantom flushing, a handle is a two-minute swap, and a rocking toilet is fixed by resetting it with a new seal. Replacement only makes sense when the tank or bowl is cracked (porcelain can't be reliably repaired), the glaze is etched and permanently stained, parts are discontinued on an old model, or you want comfort height or a water-saving upgrade. We'll tell you honestly which side of that line you're on rather than selling you a toilet a flapper would fix.

Water at the floor after flushing almost always means the wax seal has failed — either through age or because the toilet has been rocking on an uneven floor. The fix is pulling the toilet, inspecting the flange, fitting a new seal and resetting it level. It's worth doing promptly: that water is dirty, it wicks into the subfloor, and a long-running leak at the base is one of the most common causes of soft bathroom floors.

For most adults, yes. Comfort height seats sit 17 to 19 inches from the floor rather than the traditional 15, which is noticeably easier on knees, hips and backs — and it's the standard in accessible design. Taller household members and anyone with mobility concerns tend to prefer it immediately. The one caveat is very young children or very short users, who sometimes find it too high. It's the most common reason people replace a toilet that hasn't actually failed.

Almost certainly not. A phantom flush — where the toilet refills by itself every few minutes — is a worn flapper letting water seep from tank to bowl. A constantly running tank is a fill valve out of adjustment or a flapper not seating. Both are inexpensive parts fitted in a single visit. The reason it's worth fixing promptly is water: a running toilet can waste hundreds of gallons a day, and it's one of the fastest ways to run up a bill.

Yes. Every replacement includes disconnecting and removing the old toilet, taking it away and disposing of it properly — you're not left with a porcelain tank in the hallway. We also protect the floor while working, clean the area and wipe down the new unit before we leave.
