What Parts Do I Need for a New Toilet?
A practical toilet replacement checklist covering the toilet, seat, pan connector and fitting parts.
Quick checklist
- Choose the toilet type: close-coupled, back-to-wall or wall-hung.
- Check waste outlet direction and available projection from the wall.
- Confirm whether the seat, cistern fittings and fixings are included.
- Add pan connector, isolation valve and any concealed frame or flush plate if needed.
Before you buy
Bathroom products need to match the room, the pipework and the other visible fittings. The main mistake customers make is buying the headline product but forgetting small parts like wastes, traps, valves, fixings or connectors.
For the best result, measure the finished space, check the product specification, and make a short list of every related part needed before you order.
Common extras to check
- Waste fittings and traps
- Valves, connectors and fixings
- Matching finish accessories
- Delivery access for large items
- Professional installation requirements for plumbing, heating or electrical products
