Cistern and Sink Combo

Question

I cannot find a toilet and sink combination with a right side waste, so was thinking of buying a regular toilet with right side waste and a toilet/sink combination and then combining the toilet with right side waste wtih the the cistern/sink from the other toilet. I know it's a more expensive option but would this work?

Phil · Accepted Answer

I would think this was possible but would need to look or send picture to confim

Dan · Answer

Yes, it shouldn’t be a problem. You can order the pipework to suit the appliance.

Lawrence · Answer

Possibly, but are you sure that the waste is only available on one side? Have you checked with suppliers

Stanley · Answer

It should work yes. Both will need to be close coupled

Peter · Answer

Hello i just fitted atop of every basin and ttoilet combination 
the waste runs in to the cistern and will overfiow into the toilet itself

Victor · Answer

Yes, combining a regular toilet with a right-side waste outlet and a cistern/sink from a toilet/sink combination unit can work, provided the components are compatible and the modifications are carefully executed. However, there are some important considerations to ensure functionality and a seamless appearance:

Key Considerations for Combining Components

1. Compatibility of the Cistern and Base:

Ensure the cistern from the combination unit fits securely onto the toilet base with the right-side waste.

Check the connection points (screw holes, flush mechanism, and water inlet) are aligned.

Some cisterns and toilet bases have proprietary designs, so mixing brands may require adjustments.

2. Sink Integration:

The sink unit on the toilet/sink combination will rely on the cistern design for drainage and water flow.

Confirm that the cistern from the toilet/sink combo has the correct water inlet and outlet positions to work with the sink.

3. Right-Side Waste Alignment:

Verify that the waste pipe configuration of the new toilet base aligns properly with your plumbing setup.

Measure the offset carefully to avoid mismatched pipe angles, which could require additional pipework or connectors.

4. Modifications:

You may need a plumber or fitter to make adjustments, such as:

Customizing the fit between the toilet and cistern.

Ensuring watertight seals between the components.

Adjusting the sink’s drainage connection.

5. Aesthetic Considerations:

Mixing and matching components from different units may result in slight differences in design or color, which could affect the appearance.

If possible, choose components from the same brand or product line for a consistent look.

6. Cost Implications:

While this approach is more expensive than buying a pre-designed unit, it might still be more affordable than bespoke solutions.

Factor in the cost of plumbing adjustments if required.
